Answer: a. Genetic recombination (crossing over)
b. Can also be explained in terms of crossing over
c. Non disjunction of homologous chromosomes in meiosis 1
Explanation:
The process that allows for the transfer of both the paternal and maternal materials to is the crossing over process that takes at meiosis 1 changing them to secondary spermatocytes. While they are still primary spermatocytes, they are still diploid cells having both the maternal and paternal chromosomes. But since the spermatozoon is an haploid cell, it is able to retail some of both parents chromosome by the crossing over event which takes place between homologous paternal and maternal chromosomes allowing them to exchange materials. Thus the chromosomal contents of the primary spermatocyte differs from that of the spermatozoon.
C. This can occur as a result of the one of the homologous chromosome pair refusing to separate at meiosis 1 with one gamete containing 4 chromosomes/8 sister chromatids and the second having 2 chromosomes/4 sister chromatids.
Answer:
The answer is "Building artificial reefs and limiting fishing activity".
Explanation:
A variety of different methods could be used to construct an artificial island, which is most habitats are built to create a coral through using raw parts, and farming is the farming company, both "the creation of artificial reefs and restriction of fisheries" the activities are used to control environmental ecosystems throughout the region.
Oxygen is a small molecule and it's nonpolar, so it easily passes through a cell membrane. Carbon dioxide, the byproduct of cell respiration, is small enough to readily diffuse out of a cell. Small uncharged lipid molecules can pass through the lipid innards of the membrane.
When you are running at high intensity many body systems are being influenced by running and providing some responses in your body.
Running stimulates the cardio respiratory system, making your heart work harder by pumping a large amount of blood into your body, the blood flow starts to be fast and to compensate for this effort you will have to breathe more, taking more oxygen for your organs and tissues.
The muscular and bone systems are stimulated and trained providing greater resistance and strength for your muscles and lower bones.
During the run, the urinary system is also affected, because running is able to improve kidney function, allowing the expulsion of toxic substances from your body to be done more efficiently.
Finally, running stimulates the endocrine system by causing it to release hormones of well-being and relaxation that help you rest and feel good after running.
The correct answer should be D. ecological footprint
Biodiversity means having various species living together while habitat is a place of residence of species. Sustainability refers to the question whether or not something is ecologically sustainable.
