Answer: C). A tsunami would decrease abundance by causing physical damage to the organisms and their ecosystems.
An intertidal zone is also known as littoral zone. It is the region which is covers the foreshore and seabed. This region is exposed to the affects of tides. This region is highly vulnerable to tsunamis. The tsunami will disturb the habitat of organisms living in intertidal zone. Therefore, will result in decrease in abundance of aquatic organisms.
Answer:
There are two possible answers: Deep-sea vents provided the energy needed for the first organic compounds to form OR self-replicating RNA molecules passed on genetic information.
Explanation:
The reason for the first answer is due to the hypothesis that indicates that life (organic molecules) arose from inorganic molecules synthesized from the amino acids in those energy vents. This is called the metabolism first hypothesis. The Miller-Urey Experiment provided evidence that organisms could rise from inorganic molecules (they simulated under the conditions you would see on early Earth). The second hypothesis is the RNA World hypothesis (second answer) which suggests that the formation of RNA that could replicate (possible due to mutation or evolution), led to life that could preserve its genetic integrity through replication (greater stability to the organism) and create lipid bi-layer membranes/other organelles. Some scientists support the Metabolism First Hypothesis, while others are skeptical (this goes for the RNA World Hypothesis as well). However, the RNA World Hypothesis is for more reasonable in the fact that its main point is the fact that RNA molecules were able to replicate and maintain genetic stability despite early Earth conditions. Although either hypothesis could explain why all organisms share the same genetic code, the RNA World Hypothesis better explains the universality of DNA/RNA of genes that we see today.
I think hes just wanted to know if taking breath mint could cure bad breath after eating crabby patty.
Answer:
A homologous pair of chromosomes.
This set of chromosome was inherited from the mom's and dad's gametes; each gamete donated one of the chromosomes.
A diploid set of chromosomes.

From the data, the manatee population obviously increased after the regulations went into affect and the deaths due to watercraft reduced from 25 to 8 after the regulations were put into effect. The population increased by 165% from 1980=-2010 and the drop in deaths due to watercraft decreased by
68%.So this is not a direct correlation but at least it shows that the watercraft deaths decreased significantly. Since the population increased at a greater rate then it may be that more females were spared so could mate and give birth to that many more manatees.
