<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>

Xelga [282]

Don the stockings before getting out of bed in the morning.


To prevent distention of the veins, stockings should be applied before the legs are placed in a dependent position. Stockings should be used preventively before the discomfort associated with venous pressure and edema occurs. Knee-high stockings should end 2 inches (5.1 cm) below the knee to avoid popliteal pressure, which limits venous return. Stockings apply uniform pressure. Elastic bandages may slip or develop wrinkles, creating uneven pressure and constriction; edema may result.

Hello. It is not possible to access the website you are referring to, but I will try to help you in the best possible way.

Natural selection is the term created by Chales Darwin to compose a theory of biological evolution. According to this term, living beings that have characteristics favorable to their survival, in relation to the environment in which they live, are more likely to survive and pass these characteristics on to their descendants, while those that do not have these characteristics are more likely to die. .

An example of this can be seen in a population of lizards that live in environments with a lot of grass. According to natural selection, green colored lizards would have better advantages of surviving because they would be camouflaged in the grass and would not be seen by predators, unlike red lizards, which would be easily identified and captured by predators. therefore, the population of red lizards would decrease until it ceased to exist, while the population and green lizards would survive and generate other green lizards.

if a group of _____ species lived together in a small area, the carrying capacity of that area would probably collapse quickly??
alukav5142 [94]
The answer is K-selected.

The population size of K-selected species is fairly constant in time, unlike the population size of r-selected species. r-selected species are usually bellow carrying capacity and the population size is density independent. On the contrary, K-selected species are usually near or at carrying capacity and the population size is density dependent.
