I would have to say the second stage of life
Answer:
Option A, 3
Explanation:
Primarily all pea seeds have two colors one is yellow and other is green.
Let green color allele be represented by "G" and yellow color allele be represented by "g".
When we start working on pea seed color problem, there can be following possible genotypes -
a) Heterozygous green color - Gg
b) Homozygous yellow color - gg
c) Homozygous green color - GG
Hence, option A is correct.
DNA is made of chemical building blocks called nucleotides. These building blocks are made of three parts: a phosphate group, a sugar group and one of four types of nitrogen bases. To form a strand of DNA, nucleotides are linked into chains, with the phosphate and sugar groups alternating.
Protein kinases are located on the plasma membrane as integral or peripheral membrane protein so that they can more readily encounter and phosphorylate other membranes proteins.
These protein are embedded in the phospholipid layer to perform the function of plasma membrane that mainly include the selective transport of molecules and cell - cell recognition.
The plasma membrane perform the function to provide protection for cell. It differentiate between the outside and inside of the cell.
Phospholipid is the lipid membrane that usually consist of lipid bilayers. It act as barrier to protect the cell against environmental issues.

Analyze the human karyotype and give two examples of pairs of metacentric chromosomes, two examples of telocentric pairs, and two examples of acrocentric pairs.
Answer: The test that is conducted to evaluate and identity the shape,size and number of chromosomes in cells of organism is called the Karyotype.
Metacentic chromosomes are X - shaped chromosomes. They have centromere at the middle, which makes the arms of the chromosomes equal in length. Therefore any type of chromosomes with equal length of arms is said to be Metacentic. Thus chromosomes on position 1,13, 16 , 19 and 20 are examples.
When a pair of chromosomes showed a regular segregation at anaphase of meiosis, they are said to be telocentric. They are type of chromosomes in which the centromere are located at the terminal ends of the chromosomes, with the telemeres extending from theses ends.Hence during segregation, the ends of telocentric chromosomes are orientated towards the poles of the cells. example is the alphabets ''i'' shaped chromosomes in mice and 29 pairs autosomes in Angora goats.
When the centromere is located in such a way that one arm lenght of a chromosomes is longer than the other, then this is called acrocentric. Example is chromosome 21 of down syndrome.others are 13, 14, 15, 22, and Y-chromosomes.
