Let us look at the what, why and how of studying extreme places like the deep earth and the deep space. Scientists need to figure out as to 'what' they want to look at such places, be it a new exotic creature or bio-genesis (birth of life). Unless there are several testable hypothesis constructed, such a study cannot begin. The 'why' aspect deals with the purpose of such research and expeditions. Is it of any use to the humans, or will it improve our current understanding of a phenomenon? The 'how' aspect deals with the technology and the economic assistance that can help in undertaking such a research. All these are the challenges that needed to be thoroughly considered to make such a research or expedition possible.
Answer:
D 2 million years is the answer
Explanation:
Answer:
An unconditioned response.
Explanation:
Pavlov was the process of studying salivation in dogs as a part of a research program on chewing and digestion. This is known as a normal reflex that is under personal choice or control and also called an unlearned evolutionary response.
In terms of Pavlov's analysis of learning, Pavlov built a device that would help to accurately measure the amount of saliva produced by dogs. In the case of Pavlov dogs, the food is called as the stimulus and salivation is called as a response.
Egeria densa is an aquatic plant which has developed different means of carrying out photosynthesis under conditions of low carbon dioxide. During the process, the plant generate low pH at the leaf surface during high light intensity and this acidification shift the process equilibrium towards carbon dioxide which will then diffuse into the cell through passive diffusion.
Thus, if the student place the plant inside her fresh water tank, the plant will increase the carbon dioxide content of the water, which will lead to an increase in pH and the increase in pH will negatively affect the fish.
During the citric acid cycle, the
production of co2 is the result of the oxidation of intermediate compounds of
the citric acid cycle coupled to the production of ATP/GTP.
<span>The
citric acid cycle has an essential role in metabolism, and it consist of series
of steps. The citric acid cycle is also known as Krebs cycle. One other name of
this cycle is Tricarboxylic Acid (TCA)cycle.</span>
