Whitepunk [10]3 years ago

<span>First we have to know what an "internal stimulus" is. An "internal stimulus" is something INSIDE of us, that makes us want to do something. Hunger is an example of an internal stimulus. It comes from within us. And it makes us want to eat. So, since hunger is the stimulus, an appropriate response would be to eat some food. Does that make sense?</span>

The analysis of a DNA molecule reveals that 30% of its nucleotides are adenine. What percentage of the same DNA molecule would b
Contact [7]

Answer: 20%

Explanation:

Recall that the sum of all nitrogenous bases is equal to 100%.

Hence: A + C + G + T = 100%

Now, since adenine nucleotides is 30%, then thymine is 30% as well (A = T). Thus, the total of both is 60%.

From 100 remains 40% which is divided equally between guanine and cytosine, so each is 20%.

Thus, the percentage of the same DNA molecule that would be expected to be guanine nucleotides is 20%

Cells with a relatively simple cell morphology that do not have a true membrane-delimited nucleus are called.
Zarrin [17]

Cells with a relatively simple cell morphology that do not have a true membrane-delimited nucleus are called prokaryotes

<h3>What is a prokaryote?</h3>

A prokaryote is a single-celled organism that lacks a nucleus, and other membrane-bound organelles.

But in the three-domain system, based upon molecular analysis, prokaryotes are divided into two domains: Bacteria (formerly Eubacteria) and Archaea (formerly Archaebacteria). Organisms with nuclei are placed in a third domain, Eukaryota. In the study of the origins of life, prokaryotes are thought to have arisen before eukaryotes

If the velocity of a sound wave remains constant and its frequency increases, which characteristics of the wave will decrease?
ANEK [815]

Answer:

Option C is correct

Explanation:

Wavelength of the sound waves varies inversely with respect to frequency which means that if frequency increases wavelength will decrease and if  frequency decreases wavelength increase.

Mathematically this relation can be represented as -

W \alpha \frac{1}{f}

Where W represents the wavelength and f represents the frequency

When frequency is constant, wavelength exhibit direct proportionality relationship with speed.
