Answer:
Meiosis is the type of cell division in which a parent cell divides into four daughter cells. Meiosis generally occurs in the gamete or sex cells. The haploid cells are produced by the meiosis.
The original cell is diploid that contains the chromosome number (2X). The original is divided into the four daughter cell. The daughter cells produced by the meiosis contains the half chromosome number as compared with original cell (X). The crossing over occurs in meiosis and the daughter cells are quite different from the original cells.
Explanation:
Eukaryotes<span> include such microorganisms as fungi, protozoa, and simple algae. </span>Viruses<span> are considered neither prokaryotes nor </span>eukaryotes<span> because they lack the characteristics of living things, except the ability to replicate (which they accomplish only in living </span>cells<span>).</span>
The answer is; 3:1
This is derived by dividing the number of purple flowers with that of white flowers (or vice versa);
669/221 = 3.02714 which is approximately 3 (because we can only have whole plants). Based on this fact, it can be postulated that the Purple flower allele is dominant to that of white flower. (The purple flowers represent the Homozygous dominant and heterozygous population while the white flowers are the homozygous recessive population)
During germination of pollen grains, the pollen grains produce a tube that grows down towards the ovary.
Germination we can term it as the process by which an organism grows from a seed or a similar structure pollen grains are reproductive structures which are also known as pollen tubes that produce male gametophytes. The first step is germination is an emergence of radicle which helps in supply of water to the growing embryo. During germination of pollen grains, it produces a tube that grows down towards the ovary. The growth of a plant which founds with a seed is called germination and it results in the formation of the grain. The companionship of male and female reproductive cells is where the seed of the vascular plant produces. Developed seeds contain an embryo and, where plant species store of food reserves, and wrapped in a seed coat. Different numbers of seeds lack nuclei which are produced by some plants, and they are called dry seeds and they never germinate. Ripe seeds that do not grow are called dormant seeds, and they are subject to external environmental conditions of metabolic processes and cell growth are prevented. Embryonic tissues resume growth, and seed begins to germinate developing towards seedling when given proper conditions.
I’m gonna guess gene mutations is the answer
