The answer is d. mitosis.
The cells in the meristematic region of the root are
embryonic cells. Thus, these undifferentiated cells have the capacity to
undergo continuous mitotic divisions and divide into new cells. The meristematic region of the root contains meristem cells for the root growth.

Answer:
B
Explanation:
A niche refers to the way in which an organism fits into an ecological community or ecosystem. Through the process of natural selection, a niche is the evolutionary result of a species morphological (morphology refers to an organisms physical structure), physiological, and behavioral adaptations to its surroundings.
<span>A mature sporophyte produces spores by meiosis, a process which reduces the number of chromosomes to half, from 2n to n. Because meiosis is a key step in the alternation of generations, it is likely that meiosis has a fundamental adaptive function. The nature of this function is still unresolved (see Meiosis), but the two main ideas are that meiosis is adaptive because it facilitates repair of DNA damages and/or that it generates genetic variation.
The haploid spores germinate and grow into a haploid gametophyte. At maturity, the gametophyte produces gametes by mitosis, which does not alter the number of chromosomes. Two gametes (originating from different organisms of the same species or from the same organism) fuse to produce a zygote, which develops into a diploid sporophyte.</span>
For the answer to the question above, I believe the answer to the question is Antidiuretic Hormone (ADH). <span>It is a relatively small peptide molecule that is released by the pituitary gland at the base of the brain after being made nearby the hypothalamus. ADH has an antidiuretic action that prevents the production of dilute urine and it is also antidiuretic.</span>
