Why aren't there many large carnivores?
Answer:
Technically, the largest ever marine predator known thus far - the blue whale - is, for now, alive and well, but I know what you mean. You’re not talking about filter-feeders, or fish-eaters, you mean macropredators.
The last truly enormous macropredator in our oceans was probably Carcharocles megalodon, which went extinct about 3.6 million years ago. Other recent examples include the terrifying sperm whale Livyatan melvillei (which disappeared 8.9 mya) and other megatoothed sharks like C. chubutensis.
So, why did the giants go away? The answer, in truth, is likely multi-faceted. Here are some major promising hypotheses, or at least contributing factors:
Whales have declined. Giant sea carnivores like C. megalodon and Livyatan relied on marine mammals - specifically baleen whales. During the Pliocene, the Americas connected and the Central American Seaway was closed. This seems to have triggered a significant decline in the diversity of tropical whales, and would thus limit food availability for huge, energy-hungry predators.
Things got too cold. The extinction of megalodon and other giant ocean predators roughly coincides with the trend of decreasing temperatures the Pliocene brought. Giant sharks in particular, not being fully warm-blooded, would suffer from this, and it would also mean a decline in food supply. You can even see a sudden cold snap just about when Carcharocles went extinct, 3.6 mya.
Smaller predators outcompeted them. The niche of Carcharocles and the macroraptorial sperm whales is arguably still filled today - by the killer whale. Many orca pods specialize in hunting whales or other marine mammals. However, killer whales and their ancestors were perhaps more opportunistic, fast, intelligent and indeed adaptable than the massive, solitary hunters.
Ironically, the largest ever marine predator owes its existence to the demise of the largest ever marine macropredators. Since the extinction of macroraptorial sperm whales and Carcharocles megalodon, baleen whales have been gradually increasing in size, for they no longer need to be as fast and agile. Because of this, we have the privilege of sharing our world with the largest animal known to have ever lived - the blue whale.

What is the central dogma, essential truth, of biology?
Answer:
The correct answer is - C.
Explanation:
The central dogma the two-process system that is an essential truth of biology as it is the basis of complete living organisms. It is a particular pattern of information that takes place in our cells by the process known as transcription and translation.
During Transcription DNA forms the basis of RNA and then in translation, the sequence of RNA forms the amino acids and the proteins are forms by these amino acids. Proteins is the structural part of the living organism.

Why are most systems in the human body negative feedback systems?
Most systems in the human body are negative feedback systems because negative feedback systems allow humans to regulate and stabilize their systems, which is the first option as a negative feedback system regulates the body's functioning.
What is the negative feedback system?Negative feedback is a regulatory mechanism in which a change in a physiological variable triggers a response that opposes the initial change, for example, in the regulation of body temperature, when the body becomes too hot, thermoreceptors in the skin and other tissues detect the change in temperature and send signals to the hypothalamus, which acts as the body's thermostat and as a feedback mechanism, hypothalamus triggers responses that cool the body, such as vasodilation to increase blood flow to the skin, sweating to release heat, etc.
Hence, most systems in the human body are negative feedback systems because negative feedback systems allow humans to regulate and stabilize their systems, which is the first option.

Which of the following would be affected when a protein is denatured?
a.) amino groups
b.) primary structure
c.) side chains
d.) tertiary structure
"b" why because primary structure needs protein and if protein denatured,primary structure will affected instantly!
#followandheartallmyquestion
When a protein is denatured by chemical, heat or other substances, the primary structure remains intact. Hence, the correct answer would be the tertiary structure.
Denaturation of proteins generally causes the breakage of weak bonds on which the folding and the entire protein structure is built. When this happens:
the peptide bonds between the component amino acids remain intact. Hence, the primary structure is conservedthe destruction of other bonds means that the secondary and tertiary structures are affected.Agents that are capable of denaturing proteins include high temperature, changes in acidity/basicity, UV radiation, high concentration of salts, and so on.
The correct answer as to which would be affected when a protein is denatured in this case would, therefore, be the tertiary structure.
