Ninth class biology mcqs ( fungi and algae)
Both fungi and algae are eukaryotes. Fungi are heterotrophs that lack chloroplasts and can be multicellular with coenocytic hyphae. They store food as glycogen and include examples like mushrooms, yeasts, and molds. Fungi are important decomposers and sources of antibiotics. Algae are classified based on pigments and can be unicellular or multicellular. They contain chloroplasts and store food as starch. Some fungi cause diseases in plants and humans while others are used to make antibiotics, alcohol, and mushrooms are eaten.

Dear Students/Parents
We at 'Apex Institute' are committed to provide our students best quality education with ethics. Moving in this direction, we have decided that unlike other expensive and 5star facility type institutes who are huge investors and advertisers, we shall not invest huge amount of money in advertisements. It shall rather be invested on the betterment, enhancement of quality and resources at our center.
We are just looking forward to have 'word-of-mouth' publicity instead. Because, there is only a satisfied student and his/her parents can judge an institute's quality and it's faculty members coaching.
Those coaching institutes, who are investing highly on advertisements, are actually, wasting their money on it, in a sense. Rather, the money should be invested on highly experienced faculty members and on teaching gears.
We all at 'Apex' are taking this initiative to improve the quality of education along-with each student's development and growth.
Committed to excellence...
With best wishes.

8- How many times does interphase occur during meiosis- A) 0 D) 3 B) 1.docx
Interphase occurs once during meiosis. S phase is when sister chromatids are replicated. The correct order of events in Prophase I is: chromosomes condense, recombine, and then synapse. The cell described is most likely a somatic cell of a male. During Metaphase I, homologues segregate from each other. During Metaphase II, chromosomes migrate to the middle of the cell. During Anaphase II, sister chromatids segregate from each other.

Prokaryotes are decomposing bacteria that can be found in air, soil, and water. They replicate their DNA through binary fission and some secrete toxins. Prokaryotes like eubacteria and archaea lack nuclei in their cells and have peptidoglycan in their cell walls. Gram-positive bacteria are generally more resistant to antibiotics than gram-negative bacteria. Prokaryotes can take different shapes and form capsules in harsh conditions.

We at 'Apex Institute' are committed to provide our students best quality education with ethics. Moving in this direction, we have decided that unlike other expensive and 5star facility type institutes who are huge investors and advertisers, we shall not invest huge amount of money in advertisements. It shall rather be invested on the betterment, enhancement of quality and resources at our center.
We are just looking forward to have 'word-of-mouth' publicity instead. Because, there is only a satisfied student and his/her parents can judge an institute's quality and it's faculty members coaching.
Those coaching institutes, who are investing highly on advertisements, are actually, wasting their money on it, in a sense. Rather, the money should be invested on highly experienced faculty members and on teaching gears.
We all at 'Apex' are taking this initiative to improve the quality of education along-with each student's development and growth.
Committed to excellence...
With best wishes.

8- How many times does interphase occur during meiosis- A) 0 D) 3 B) 1.docx
Interphase occurs once during meiosis. S phase is when sister chromatids are replicated. The correct order of events in Prophase I is: chromosomes condense, recombine, and then synapse. The cell described is most likely a somatic cell of a male. During Metaphase I, homologues segregate from each other. During Metaphase II, chromosomes migrate to the middle of the cell. During Anaphase II, sister chromatids segregate from each other.

Prokaryotes are decomposing bacteria that can be found in air, soil, and water. They replicate their DNA through binary fission and some secrete toxins. Prokaryotes like eubacteria and archaea lack nuclei in their cells and have peptidoglycan in their cell walls. Gram-positive bacteria are generally more resistant to antibiotics than gram-negative bacteria. Prokaryotes can take different shapes and form capsules in harsh conditions.

Temple of Asclepius in Thrace. Excavation results
The temple and the sanctuary around were dedicated to Asklepios Zmidrenus. This name has been known since 1875 when an inscription dedicated to him was discovered in Rome. The inscription is dated in 227 AD and was left by soldiers originating from the city of Philippopolis (modern Plovdiv).
How to Make a Field Mandatory in Odoo 17
In Odoo, making a field required can be done through both Python code and XML views. When you set the required attribute to True in Python code, it makes the field required across all views where it's used. Conversely, when you set the required attribute in XML views, it makes the field required only in the context of that particular view.

This document provides an overview of wound healing, its functions, stages, mechanisms, factors affecting it, and complications.
A wound is a break in the integrity of the skin or tissues, which may be associated with disruption of the structure and function.
Healing is the body’s response to injury in an attempt to restore normal structure and functions.
Healing can occur in two ways: Regeneration and Repair
There are 4 phases of wound healing: hemostasis, inflammation, proliferation, and remodeling. This document also describes the mechanism of wound healing. Factors that affect healing include infection, uncontrolled diabetes, poor nutrition, age, anemia, the presence of foreign bodies, etc.
Complications of wound healing like infection, hyperpigmentation of scar, contractures, and keloid formation.
