Really, Geny? Really?
I am almost done... look...

Turtles get affected by seasonal changes because the climate is warm, more and more eggs will become female, which will then lead to less genetic diversity in sea turtle populations.
Snakes, such as the garter snake, use the changes in temperature between seasons to time their reproduction and hibernation. These snakes slither into the underground dens they have built to wait for the cold temperatures to stop. Once it gets warm again, garter snakes are done with hibernation. They come out from their little homes to court and reproduce.
Water Lily - As the summer heat rolls in, the shade that ends up being provided by the water lilies became increasingly important for keeping fish and other aquatic animals cool. The shade also causes the growth of algae to be limited, which might otherwise bloom more than it needs to, which would then lead to decreased oxygen levels in the water. It would also cause many fish to die, as well as other species.
Meiosis creates gametes (eggs and sperm) with only a single chromosome set (haploid or n) from parental cells with two chromosome sets (diploid or 2n). During fertilization, the haploid sperm (n) and egg (n) fuse, producing a diploid zygote (2n). The cells of the zygote then divide by mitosis (which does not change the ploidy level) to produce an adult organism (still 2n) of the next generation.
<span>In sexual life cycles, meiosis and fertilization keep the number of chromosomes constant from generation to generation. </span>
Answer:
A. All organisms have a common biochemical evolutionary origin.
Explanation:
Genetic code is the biological mechanism by which the DNA in our body is used to synthesize protein needed for growth and development. The genetic code comprises of all the possible 64 codons i.e. a group of three nucleotides that encode an amino acid.
One of the characteristics of the genetic code is that it is UNIVERSAL. This means that all known living organisms make use of the same genetic code and hence, this portrays that all living organisms share a common biochemical evolutionary origin.
Answer:
During anaphase 2, the chromosomes' centromeres break, and the spindle fibers pull the chromatids apart. The two split portions of the cells are officially known as "sister chromosomes" at this point.
Explanation:
