Answer:
abt 24 contraction per min is needed to maintain a relatively stable internal solute conc.
paramecium maintain its volume by preventing itself from shrinking by holding in as much water as it can.
When the water solute concentration is reduced, the number of vacuole contractions will increase. But when the water solute concentrations rise, the number of vacuole contraction will decrease.
When the number of vacuole contractions will increase, the water solute concentration is reduced. But when the water solute concentrations rise, the number of vacuole contraction will decrease. So it is cetris paribus, means when the one is increase the other one will decrease.
Answer: The question is is incomplete, here are the options.
A.Loonand O Charles Darwin named them Geospiza leodarwini in honor of his son Leonard.
B. They come from the Darwin archipelago off the coast of Ecuador C. C. Charles Darwin collected the first scientific specimens.
D.John Gould placed them in the genus Darwinospiza
Correct option is C.
Explanation:
Charles Darwin collected the first scientific specimens.
Darwin's finches play vital role in the development of Darwin's theory of evolution and natural selection. This is because the birds called Darwin's finished have variable size and shape making them important for the development of the theory.
Theory of natural selection and evolution which was developed by Darwin states that organisms changes over time as a result in variation in it's characteristics or behavioral traits to survive , adapt and reproduce in it's environment.
In a particular context, “epoch” can refer to a particular point of time characterized by a particular event/series of events.
While “era” refers to a period of time characterized by events in a chronological order.
Thus, an “era” can encompass more than one “epoch”.
“Period” can refer to a short interval of time or a very long interval of time.
For example:
<span>“My period of happiness….”“The period of Four Horsemen…”</span>
<span>“Eon” </span>refers to an indefinitely long time. <span>Eon is presumed to consist of at least 2 eras.</span>
I think, Lipogenesis is a common for organic molecules because the intermediate Acetyl-CoA is formed in most metabolic processes. Lipogenesis involves the formation of fatty acids from Acetyl-CoA. Acetyl-CoA is an intermediate stage in metabolism of simple sugars, such as glucose, which is the preferred source of energy for most living organisms.
