Use the diagram below to help you to choose ALLL the CORRECT answers for the question: What are the differences between Meiosis i and Meiosis II?
(MULTIPLE CHOICE)
A In Metaphase I and Metaphase II the chromosomes line up differently because there are a different number of copies
B Telophase and cytokinesis do NOT happen in Meiosis II
C After Meiosis II the 4 daughter cells undergo cell specialization to become eggs or sperm, which does not happen after Meiosis I
D In Prophase I the chromosomes crossover, in Prophase II they do not crossover
Answers
Answer:
D In Prophase I the chromosomes crossover, in Prophase II they do not crossover
Explanation:
Meiosis is a type of cell division in which four daughter cells, which are genetically different from one another, are produced. The daughter cells have their chromosomal number reduced by half. Since, the meiotic process aims at producing haploid gametes, it occurs in a series of two-division steps viz: meiosis I and meiosis II.
Meiosis I involves the separation of homologous chromosomes into two daughter cells while the meiosis II involves separation of chromatids to make four daughter cells. One major difference between meiosis I and meiosis II is that in the PROPHASE of meiosis I, a unique process called CROSSING OVER occurs but does not occur in meiosis II (as seen in the attached image).

If a specific gene code for a polypeptide is 120 amino acids long, approximately how many nucleotides long is the mRNA that codes for this polypeptide?
Answers
Answer:
360 nucleotides
Explanation:
Each amino acid corresponds to a specific codon, a sequence of three DNA or RNA nucleotides.
If there are 120 amino acids and a sequence of three nucleotides corresponds to one amino acid, then 120 × 3 = 360 nucleotides.
Hope that helps.

Answers
Answer:
B) A little cellular respiration was taking place but not enough for growth.
Explanation:
Germination is a biological process that has a high energy demand, this requirement being fulfilled by cellular respiration. Cellular respiration enables the germinating seeds to convert chemical energy from oxygen (O2) molecules and nutrients into adenosine triphosphate (ATP), the energy currency of the cells. Cellular respiration increases as seeds emerge and begin to germinate. In this case, cellular respiration was not enough to fulfill the energy requirements of the germinating soybean seeds, which can be measured by the amount of O2 consumed during this process.

describing the process of photosynthesis) The process of photosynthesis
Answers
Photosynthesis is the process through which plants obtain their food from sunlight, also,many plants take light energy and convert into chemical energy with the help of chlorophyll pigment (green pigment)......
The process through which green plants and other organisms convert light energy into chemical energy is known as photosynthesis. Light energy is gathered and utilized during photosynthesis in green plants to transform water, carbon dioxide, and minerals into oxygen and energy-rich organic substances.
During this process, water is taken from the soil by the root hairs and transported to the leaves through the xylem vessels. Carbon dioxide enters through the stomata. The chlorophyll breaks water molecules into hydrogen and oxygen by absorbing the sun's light energy.
To produce glucose, carbon dioxide from the air and hydrogen from water molecules are combined. Additionally, as a waste material, oxygen is emitted into the atmosphere through the leaves.
While the rest is stored in the roots, leaves, and fruits for further use, glucose serves as a source of nourishment for plants, giving them the energy they need for growth and development.
Other essential biological elements of photosynthesis include pigments. They are the compounds that give color and absorb light at a certain spectrum while reflecting the light that was not absorbed. Chlorophyll and carotenoids, found in the membrane of chloroplasts, are the main components of all green plants. Its main purpose of it is to absorb light energy.

Sometimes cells make mistakes in copying their genetic information, causing mutations. Mutations can be irrelevant, or they can affect the way proteins are made and genes are expressed.
Genetic mutations are _____ harmful.
Answers
Genetic mutations may or may not be harmful, because if the mutation takes place in the exons region of the gene, then it is harmful, but if the mutation takes place in the introns, then it is not harmful.
What are the impacts of the genetic mutation?The genetic mutation occurs for a variety of reasons, including environmental factors, carcinogen products, or radiation, and the mutation's transmission depends on the site of the mutation. If the mutation happens in the somatic cells, then it is not likely to pass to the next generation, but if the genetic mutation takes place in the germ line cells, then it is more likely to pass to the offspring.
Hence, genetic mutations may or may not be harmful, because if the mutation takes place in the exons region of the gene, then it is harmful, but if the mutation takes place in the introns, then it is not.
