ASAP PLS There are lots of big words in genetics! One way to start thinking about the process of meiosis is to ask yourself some
mihalych1998 [28]

Answer:

1) the genes and chromosomes do not double after each generations because parental sex cells are haploid and only contain one set of chromosomes. During fertilization the two cells fuse to form a diploid zygote with two copies of genes and chromosomes. For example a normal human has 46 chromosomes (2 copies of 23 chromosomes) during reproduction gametes which contain 23 chromosomes (haploid) fuse to form an offspring with the correct number of chromosomes ( 23 + 23 = 46).

2) offspring only receive one set of chromosomes from each parent so to maintain the chromosome number of humans. If this did not happen you would not be the same species.

PLS HELP!!! What best describes the relationship between
rusak2 [61]

Answer:

Interspecific competition

Explanation:

Interspecific competition occurs when two different species occupy the same environment as they coexist and depend on the same limited resources for survival. As a result of these limited resources, there's competition between the different species with each species having their different levels of fitness. Their level of fitness determines how well they will complete with other species. This will also determine if they will go extinct or thrive in such environment where there's interspecific competition.

The graph given shows the growth of the relative population size of two different species grown together.

It shows that P. aurelia, with time, outcompetes P. coudatum.

This graph clearly suggest that interspecific competition has occurred. Both species are competing for the same limited resources.

P. aurelia has a greater fitness which enables it to outcompete the other species sharing the same environment with it.

Interspecific competition beats describes the relationship between the two species in graph B.
