Part A: Briefly, explain the current hypotheses about how brown algae, red algae, chlorophytes and charophytes (couple of groups of green algae), and land plants are related. What are the characteristics of the land plants that distinguish it from the most closely related algal group, and (if applicable) how do each of these characteristics benefit plants in a terrestrial environment? Part B: What are the differences between plant cells, animal cells, and bacterial cells. And what are the characteristics of different plant cell types. Solution (1)Evolution of plants has facilitated the survival of life on earth and these land plants has their monophyletic lineage embedded with that of green algae and these green algae are believed to be the oldest eukaryotic lineages. Hypothesis states that land plants are related to brown algae, red algae, chlorophytes and charophytes. There are so many evidences to prove that these land plants share similar characteristics with that of brown algae, red algae, chlorophytes and charophytes. Plants and algae are eukaryotic and both posses the chlorophyll, which allows them to make their own food, both plants and algae have similar cell walls, stores energy in the form of starch, follows two stage life cycle. Sporopollenin, chlorophyll a, cellulose, chlorophyll b are common to both charophytes and land plants, but plants has lignin and is absent in case of charophytes. Some green algae exhibit alternation of generations like plants. All land plants exhibit alternation of generations. But no charophytes exhibit alternation of generations. Charophytes are very similar to plants as they both have homologous chloroplasts (chlorophyll b, beta carotene is present, thylakoid are arranged as grana, DNA as genetic material), with respect to biochemical similarity, both has cellulose cell wall, similar enzymes in peroxisomes, when it comes to mitosis and cytokinesis, follow similar mechanisms like disappearance of nuclear envelope and till cytokinesis the spindle will remain. Based on the above features the Charophytes are considered as the closest living algal relatives of land plants Most of the varieties of algal species live in extremely damp terrestrial environment, whereas most of the plants live on land and some plants can live in water also, but algae cannot survive on dry soil and they are very adapted to it. In case of alga, the surrounding water supports it and the whole alga is involved in helping it in the process of photosynthesis, absorption of water and minerals, holdfast will provides the anchoring. But in case of plants, each and every organ is specialized for different functions, like leaves for photosynthesis, cuticle to prevent water loss, stomata for gaseous exchange, stem to support, root to provide anchorage. But alternation of generation is absent in charophytes, but it is found in all plants providing them extra benefit to survive. 2) Animal Cell Plant cell Bacteria These are eukaryotes These ar.

Monomeric single pass trans-membrane proteins generally span the bilayer membrane with an alphahelical domain. Which of the three sequences below is most likely to be a trans-membrane segment. A. I T L I Y F G N M S S V T Q T I L L I S B. I L L I F F G V M A L V I V V I L L I A C. L L K K F F R D M A A V H E T I L E E S EXPLAIN YOUR ANSWER DO NOT JUST ANSWER THE QUESTION!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! Solution A Trans-membrane Protein (TP) is a type of integral membrane protein. A Trans-membrane Protein is called so because the polypeptide chain is exposed on both sides of the biological membrane. It spans the entire biological membrane or plasma membrane and is attached to it permanently. They function as gateways to permit the transport of specific substances across the plasma membrane. For this, these proteins (TP) undergo a conformational change that is a temporary change in their structure. Trans-membrane Segment: It usually denotes a single trans membrane alpha helix of a trans membrane protein, also known as an integral protein. This segment is thermodynamically stable in the membrane. We all know that the secondary structure of proteins refers to the spirally coiled polypeptide chain called alpha helical form or alpha helix. Of the three 20 amino acid trans membrane sequences; Sequence B is most likely to be a trans- membrane segment because it is composed primarily of hydrophobic amino acids, therefore can be stably integrated into lipid bilayer. Sequence A: It contains many polar amino acids therefore it cannot be integrated into the hydrophobic interior of lipid bilayer of plasma membrane. Sequence C: It contains many charged amino acids which again is disfavored into the hydrophobic interior of lipid bilayer..

Indicate all persons/investigators participating in the Program and explain the role of each participant in the Program. To test the mir-22 function of cancer patients (blood sampling). Note that the type of study is basic research Solution Answer: The participants/investigators participating in a program includes the PI (Principal Investigator), Co-PI (Co-Principal Investigator), faculty participants and human participants. Role of each of them have been discussed below: 1. PI-The primary person to conduct a public service project or sponsored project in accordance with the laws and regulations of the institution concerned. 2. Co-PI- They have responsibilities similar to the PI and has obligations to monitor as to whether the projects are conducted in compliance with the rules and regulations. 3. Faculty participant- They are not directly involved in the research projects, but may act as a key personnel with lesser responsibilities than the PI and Co-PI. 4. Human participant- These are individuals upon whom the investigators conduct research to obtain data either through direct intervention or obtaining individual information about the participant which are not to be made public. Before collecting blood for sampling to study mir-22 function in cancer patients, the human participants should be fully informed (by the investigators) about the facts, benefits, risks and discomforts they might face during the program. These factors are part of the ethical and legal aspects as these might change the participants willingness to participate in the program. The research protocols includes diet, survey, experimental drug intervention and exercise studies. For children (below 18 years), prior consent of the parents are standard requirements. Consents in most cases are to be documented, although it might be waived in special cases..

In the context of materials science & engineering, what is the difference between Curie temperature and Debye temperature? Solution Curie temperature (TC), or Curie point, is the temperature at which certain materials lose theirpermanent magnetic properties, to be replaced by induced magnetism. The Curie temperature is named after Pierre Curie, who showed that magnetism was lost at a critical temperature. Debye temperature is thetemperature of a crystal\'s highest normal mode of vibration, i.e., the highest temperature that can be achieved due to a single normal vibration.

How does the shape of cellulose make possible its function? Note the arrangement of individual cellulose molecules and bonds as part of your answer and mention something about both covalent and noncovalent bonds. If you really want to see the H bonds, right click on the jsmol figure, choose \"style\" \"hydrogen bonds\" and then set their diameter to 30 Angstroms. You can also choose \"color\" and make them some other color to make them easier to see! Solution Cellulose is the most abundant organic compound on earth. It is a major component of tough cell walls that surround plant cells, and is what makes plant stems, leaves, and branches so strong. Its unique, rigid structure serves an important function in plants. Its molecules are joined together using hydrogen bonds and are arranged parallel to one another, forming a long, cable-like structure that merges with other cellulose molecules. This creates the strong support structure that allows plants to stand upright. Note: Image is missing in the question.

First year students: Mean 125, SD?, size 350 Third year students: Mean 112, SD?, size 150 Significance level = 0.02 Solution Let group 1 = first year group 2 = third year Formulating the hypotheses Ho: p1^ - p2^ >= 0 Ha: p1^ - p2^ < 0 Here, we see that pdo = 0 , the hypothesized population proportion difference. Getting p1^ and p2^, p1^ = x1/n1 = 0.357142857 p2 = x2/n2 = 0.746666667 Also, the standard error of the difference is sd = sqrt[ p1 (1 - p1) / n1 + p2 (1 - p2) / n2] = 0.043783715 Thus, z = [p1 - p2 - pdo]/sd = -8.896545395 As significance level = 0.02 , then the critical z is zcrit = -2.053748911 Also, the p value is P = 2.8806E-19 Thus comparing z and zcrit (or p and significance level), then we REJECT THE NULL HYPOTHESIS. Thus, there is significant evidence that the proportion of third year students who buy used textbooks is greater than the proportion of first year student who buy used textbooks. [CONCLUSION].

Explain clearly how pseudonyms become credentials in VANETs? Explain clearly how pseudonyms become credentials in VANETs? Solution Each vehicle is equipped with a set of short-term certificates, termed pseudonyms, each with a corresponding short-term private key to sign outgoing messages. Example: Vehicle A digitally signs outgoing messages (time- and geo-stamped) with the private key, kiv , corresponding to the pseudonym Piv({Piv}(PCA) represents the pseudonym signed by the pseudonym issuer) and is attached to messages to facilitate verification on the receiver side. Receiving vehicles B and C verify the pseudonym {Piv}(P CA) and validate the signature (assuming they trust the pseudonym issuer discussed below). This process ensures the authenticity and integrity of the message and enables further validation based on its content. At the same time, transmissions by vehicle A do not reveal its identity (as the short-term certificates are anonymised), and messages signed under different pseudonyms (with different private keys) are, in principle, unlinkable. Vehicles switch from one pseudonym to another (not previously used) to achieve unlinkability of authorities with distinct roles: the Root Certification Author- ity (RCA), the Long Term Certification Authority (LTCA), the Pseudonym Certification Authority (PCA), and the Resolution Authority (RA). Different proposals may refer to these entities with various names, e.g., CAMP refers to the LTCA as the Enrollment Certification Authority (ECA). The RCAs are the highest-level authorities certifying LTCAs, PCAs, and RAs. An LTCA is responsible for registering vehicles and issuing Long Term Certificates (LTCs). A PCA issues sets of pseudonyms for the registered vehicles. An RA can initiate a process to resolve a pseudonym, i.e., identify the long-term identity of the vehicle that used (in a nonrepudiable manner) its short-term keys and credentials..

Explain the use and importance of the scientific name, genus and species. Explain the use and importance of the scientific name, genus and species. Solution Scientific Names(May be called Binomial Nomenclature) is the system of nomenclature in which two terms (mostly Latin forms,sometimes others are also used)are used to denote a species of living organism(The 1 st one is for Genus and the 2nd one is for species). e.g-Escherichia coli, Lactobacillus acidophilus IMPORTANCE- 1.Universal- Everyone in the world use the specific name to identify the specific organism. 2.organisms are easily categorized. 3.The chance of nomenclature is reduced. IMPORTANCE OF GENUS- The genus name forms the first part of the binomial nomenclature for each species. In the hierarchy of biological classification genus comes above species and below family. IMPORTANCE OF SPECIES- Basic unit of biological hierarchy It forms the second part of the biological binomial nomenclature. there are many species under a common genus..
