This daily lesson log outlines a science teacher's weekly lesson plan covering light reflection in mirrors. The lessons are designed to: 1) determine the characteristics of images formed by plane mirrors; 2) compare the angles of incidence and reflection; 3) demonstrate mirror reversal effects; and 4) introduce the differences between concave and convex mirrors. Students will participate in hands-on activities and view educational videos. The teacher aims to assess student understanding through formative assessments and identify those needing remediation.
this presentation will hepl you in studying and reviewing to cope up with your lessons. Because mirrors reflect light, they create an illusion of open space by doubling whatever is in a room. Interior decorators use mirrors to make rooms feel larger and more inviting than they truly may be. Certain styles of mirrors may give a room a certain atmosphere based on their appearance. Additionally, decorators may use lenses to reflect light or add color. They may place candles on mirrors to magnify the shimmering effect or use a series of prisms to create rainbows in a white room.

A brief information about the SCOP protein database used in bioinformatics.
The Structural Classification of Proteins (SCOP) database is a comprehensive and authoritative resource for the structural and evolutionary relationships of proteins. It provides a detailed and curated classification of protein structures, grouping them into families, superfamilies, and folds based on their structural and sequence similarities.
Cancer cell metabolism: special Reference to Lactate PathwayAADYARAJPANDEY1
Normal Cell Metabolism:
Cellular respiration describes the series of steps that cells use to break down sugar and other chemicals to get the energy we need to function.
Energy is stored in the bonds of glucose and when glucose is broken down, much of that energy is released.
Cell utilize energy in the form of ATP.
The first step of respiration is called glycolysis. In a series of steps, glycolysis breaks glucose into two smaller molecules - a chemical called pyruvate. A small amount of ATP is formed during this process.
Most healthy cells continue the breakdown in a second process, called the Kreb's cycle. The Kreb's cycle allows cells to “burn” the pyruvates made in glycolysis to get more ATP.
The last step in the breakdown of glucose is called oxidative phosphorylation (Ox-Phos).
It takes place in specialized cell structures called mitochondria. This process produces a large amount of ATP. Importantly, cells need oxygen to complete oxidative phosphorylation.
If a cell completes only glycolysis, only 2 molecules of ATP are made per glucose. However, if the cell completes the entire respiration process (glycolysis - Kreb's - oxidative phosphorylation), about 36 molecules of ATP are created, giving it much more energy to use.
IN CANCER CELL:
Unlike healthy cells that "burn" the entire molecule of sugar to capture a large amount of energy as ATP, cancer cells are wasteful.
Cancer cells only partially break down sugar molecules. They overuse the first step of respiration, glycolysis. They frequently do not complete the second step, oxidative phosphorylation.
This results in only 2 molecules of ATP per each glucose molecule instead of the 36 or so ATPs healthy cells gain. As a result, cancer cells need to use a lot more sugar molecules to get enough energy to survive.

introduction to WARBERG PHENOMENA:
WARBURG EFFECT Usually, cancer cells are highly glycolytic (glucose addiction) and take up more glucose than do normal cells from outside.
Otto Heinrich Warburg (; 8 October 1883 – 1 August 1970) In 1931 was awarded the Nobel Prize in Physiology for his "discovery of the nature and mode of action of the respiratory enzyme.
WARNBURG EFFECT : cancer cells under aerobic (well-oxygenated) conditions to metabolize glucose to lactate (aerobic glycolysis) is known as the Warburg effect. Warburg made the observation that tumor slices consume glucose and secrete lactate at a higher rate than normal tissues.
Slide 1: Title Slide
Extrachromosomal Inheritance
Slide 2: Introduction to Extrachromosomal Inheritance
Definition: Extrachromosomal inheritance refers to the transmission of genetic material that is not found within the nucleus.
Key Components: Involves genes located in mitochondria, chloroplasts, and plasmids.
Slide 3: Mitochondrial Inheritance
Mitochondria: Organelles responsible for energy production.
Mitochondrial DNA (mtDNA): Circular DNA molecule found in mitochondria.
Inheritance Pattern: Maternally inherited, meaning it is passed from mothers to all their offspring.
Diseases: Examples include Leber’s hereditary optic neuropathy (LHON) and mitochondrial myopathy.
Slide 4: Chloroplast Inheritance
Chloroplasts: Organelles responsible for photosynthesis in plants.
Chloroplast DNA (cpDNA): Circular DNA molecule found in chloroplasts.
Inheritance Pattern: Often maternally inherited in most plants, but can vary in some species.
Examples: Variegation in plants, where leaf color patterns are determined by chloroplast DNA.
Slide 5: Plasmid Inheritance
Plasmids: Small, circular DNA molecules found in bacteria and some eukaryotes.
Features: Can carry antibiotic resistance genes and can be transferred between cells through processes like conjugation.
Significance: Important in biotechnology for gene cloning and genetic engineering.
Slide 6: Mechanisms of Extrachromosomal Inheritance
Non-Mendelian Patterns: Do not follow Mendel’s laws of inheritance.
Cytoplasmic Segregation: During cell division, organelles like mitochondria and chloroplasts are randomly distributed to daughter cells.
Heteroplasmy: Presence of more than one type of organellar genome within a cell, leading to variation in expression.
Slide 7: Examples of Extrachromosomal Inheritance
Four O’clock Plant (Mirabilis jalapa): Shows variegated leaves due to different cpDNA in leaf cells.
Petite Mutants in Yeast: Result from mutations in mitochondrial DNA affecting respiration.
Slide 8: Importance of Extrachromosomal Inheritance
Evolution: Provides insight into the evolution of eukaryotic cells.
Medicine: Understanding mitochondrial inheritance helps in diagnosing and treating mitochondrial diseases.
Agriculture: Chloroplast inheritance can be used in plant breeding and genetic modification.
Slide 9: Recent Research and Advances
Gene Editing: Techniques like CRISPR-Cas9 are being used to edit mitochondrial and chloroplast DNA.
Therapies: Development of mitochondrial replacement therapy (MRT) for preventing mitochondrial diseases.
Slide 10: Conclusion
Summary: Extrachromosomal inheritance involves the transmission of genetic material outside the nucleus and plays a crucial role in genetics, medicine, and biotechnology.
Future Directions: Continued research and technological advancements hold promise for new treatments and applications.
Slide 11: Questions and Discussion
Invite Audience: Open the floor for any questions or further discussion on the topic.

Ultraviolet-visible spectroscopy is an analytical method that can measure the amount of light received by the analyte.
THE IMPORTANCE OF MARTIAN ATMOSPHERE SAMPLE RETURN.Sérgio Sacani
The return of a sample of near-surface atmosphere from Mars would facilitate answers to several first-order science questions surrounding the formation and evolution of the planet. One of the important aspects of terrestrial planet formation in general is the role that primary atmospheres played in influencing the chemistry and structure of the planets and their antecedents. Studies of the martian atmosphere can be used to investigate the role of a primary atmosphere in its history. Atmosphere samples would also inform our understanding of the near-surface chemistry of the planet, and ultimately the prospects for life. High-precision isotopic analyses of constituent gases are needed to address these questions, requiring that the analyses are made on returned samples rather than in situ.
Richard's aventures in two entangled wonderlandsRichard Gill
Since the loophole-free Bell experiments of 2020 and the Nobel prizes in physics of 2022, critics of Bell's work have retreated to the fortress of super-determinism. Now, super-determinism is a derogatory word - it just means "determinism". Palmer, Hance and Hossenfelder argue that quantum mechanics and determinism are not incompatible, using a sophisticated mathematical construction based on a subtle thinning of allowed states and measurements in quantum mechanics, such that what is left appears to make Bell's argument fail, without altering the empirical predictions of quantum mechanics. I think however that it is a smoke screen, and the slogan "lost in math" comes to my mind. I will discuss some other recent disproofs of Bell's theorem using the language of causality based on causal graphs. Causal thinking is also central to law and justice. I will mention surprising connections to my work on serial killer nurse cases, in particular the Dutch case of Lucia de Berk and the current UK case of Lucy Letby.

The increased availability of biomedical data, particularly in the public domain, offers the opportunity to better understand human health and to develop effective therapeutics for a wide range of unmet medical needs. However, data scientists remain stymied by the fact that data remain hard to find and to productively reuse because data and their metadata i) are wholly inaccessible, ii) are in non-standard or incompatible representations, iii) do not conform to community standards, and iv) have unclear or highly restricted terms and conditions that preclude legitimate reuse. These limitations require a rethink on data can be made machine and AI-ready - the key motivation behind the FAIR Guiding Principles. Concurrently, while recent efforts have explored the use of deep learning to fuse disparate data into predictive models for a wide range of biomedical applications, these models often fail even when the correct answer is already known, and fail to explain individual predictions in terms that data scientists can appreciate. These limitations suggest that new methods to produce practical artificial intelligence are still needed.
In this talk, I will discuss our work in (1) building an integrative knowledge infrastructure to prepare FAIR and "AI-ready" data and services along with (2) neurosymbolic AI methods to improve the quality of predictions and to generate plausible explanations. Attention is given to standards, platforms, and methods to wrangle knowledge into simple, but effective semantic and latent representations, and to make these available into standards-compliant and discoverable interfaces that can be used in model building, validation, and explanation. Our work, and those of others in the field, creates a baseline for building trustworthy and easy to deploy AI models in biomedicine.

and skills in daily living
Why is the word
“AMBULANCE” written in
reversed?
A periscope is an instrument
for observation over, around or
through an obstacle. Explain
how light travels in a
periscope.
Brainstorming activity
on the application of
reflection of light in
mirrors as in hallways,
parlors, etc.
Ask the students to tell
where they can apply
the concept of concave
and convex mirrors.

R. Making generalizations
and abstractions about
the lesson
The distance of the object from
the mirror is the same as the
distance of the image from the
mirror.
The height and the width of the
object is the same as the height
and width of the image as seen
from the plane mirror.
The law of reflection states
that
“The angle of incidence is
equal to the angle of
reflection”
“ The normal line, incident
ray, and the reflected ray lie
on the same plane.”
The image formed by a
plane mirror is always
erect, virtual, laterally
reversed, same size as the
object and found to be
apparently behind the
mirror.
As the between two
mirrors decreases, the
number of images
increases. Conversely,
as the angle between
the mirrors increases,
the number of images
formed decreases.
The number of images is
inversely proportional
A concave mirror is a
curved mirror in which
the reflective surface
bulges away from the
light source.
A convex mirror in
which the reflective
surface bulges towards
the light source.
to the angle between
two mirrors.

The mirrors placed
parallel facing each
other makes an infinite
number of images.

S. Evaluating learning 1. You might have noticed
that emergency vehicles such
as ambulances are often
labeled on the front hood with
reversed lettering (e.g.,
ECNALUBMA). Explain why
this is so.
Answer: Most drivers
will view the ambulance
in their rear-view
mirrors. As such, they
will be viewing an image
of the lettering. Such
images appear
with left-right reversal
and so will be viewed
with the proper
orientation -
AMBULANCE.
2. If Suzie stands 3 feet in
front of a plane mirror, how far

Describe the image formed
by plane mirror.

students will identify
what type of curved
mirror.
the person will her image be
located?
Answer: Suzie (the
object) is located 3 feet
from the mirror. Suzie's
image will be located 3
feet behind the mirror.
Thus, the distance
between Suzie and the
image will be 6 feet.

T. Additional activities for
application or
remediation
Let the students do a
brainstorming activity on other
possible signage. Ask them to
cite the relevance to the
society.
Think of an optical instrument
that employs the concept of
reflection of light.

XI. PROCEDURES
A. Reviewing previous
lesson or presenting
the new lesson
Review the differences
between a concave and a
convex mirror.
Recall the image formed by
curved mirrors.
Recall the image formed
by curved mirrors through
ray diagram.
B. Establishing a
purpose for the
lesson
Tell the students that based on
their previous discussion that a
concave and a convex mirror
formed different images.
Tell the students that another
way of describing the image
formed by curved mirrors is
through ray diagram.
Tell the students ray
diagrams provide useful
information about the
image formed but it does
not provide the information
in quantitative form.
C. Presenting
examples/Instances
of the new lesson.
The teacher will show a video
clip of the images formed by a
concave and convex mirror.
The will present the four
principal rays in curved
mirrors that is used in ray
diagramming. (Refer to LM pp

formed on a concave and
convex mirror.
F. Developing mastery
(leads to Formative
Assessment 3)
What happens to the size and
location of the image when you
bring the object nearer to the
concave mirror? Convex
mirror?
How does the location of the
object affect the
characteristics and location of
the image formed in a
concave mirror? Convex
mirror?
Give more problem
solving.
23. 23
G. Finding practical
application of
concepts and skills in
daily living
Cite practical applications of
concave and convex mirror.
H. Making
generalizations and
abstractions about
the lesson
The size of the image increases
and the location moves farther
when you bring the object near
the concave mirror.
The images formed by a
concave mirror can be real or
virtual depending on the
location of the object.
The images formed by convex
mirrors are virtual.
To generalize the topic on
image formation through ray
diagram, the teacher may ask
the students the location,
orientation, size and type of
image formed in curved
mirrors given different object
location.
The mirror equation
applies to both concave
and convex mirror.
However, for all locations
of objects in front of the
convex mirror, the image
always appears as if it is
located behind the mirror.
The image formed by a
concave mirror may be
real or virtual depending
on the object location.
