Explanation:
The animal kingdom has a great diversity in morphology and conduct, but they have different properties with the other kingdoms like sexual reproduction and autonomous movility. Also most of the living things of this kingdom are multicelulars.
Meiosis I produces two cells, both of which are haploid. This means each cell has half the number of chromosomes as the parent cell. This is a crucial step in sexual reproduction, promoting genetic diversity.
Meiosis I produces two cells, each of which is haploid.
During the process of meiosis, a cell initially has two copies of each chromosome, one from the mother and one from the father (46 in humans). This is called a diploid state. However, after meiosis I, it splits into two cells each containing half the number of chromosomes (23 in humans). These cells are said to be haploid because they only possess one copy of each chromosome. The division which occurs during meiosis I is a fundamental part of the sexual reproduction process, as it leads to genetic diversity in offspring.

how do organisms with many cell types develop from a single cell
Answer:
A multicellular organism develops from a single cell (the zygote) into a collection of many different cell types, organized into tissues and organs.During development, cells use both intrinsic, or inherited, information and extrinsic signals from neighbors to "decide on" their behavior and identity.
B. slowly degrading chemicals
C. coastal mining booms
D. improperly disposed trash
