erastova [34]4 years ago
4 0

Answer:

27

Explanation:

The number of protons in atom is the atomic number. For a neutral atom that has not lost or gained any electron, it is the same as the number of electrons.

The atomic number is used in perfect ordering of the periodic table and it is the basis of the periodic law.

Protons are positively charged subatomic particles that reside in the in the nucleus of an atom with the neutrons.

Section 2: HUMAN IMPACT
madreJ [45]

Human behaviors greatly impact the environment by overpopulation, pollution, burning fossil fuels, and deforestation.

<h3>How human behaviors impact the environment?</h3>

Humans impact the environment in many ways such as overpopulation, pollution, burning of fossil fuels, and deforestation. These changes triggered the climate change, soil erosion, poor air quality, and undrinkable water. So that's why we can say that human intervention in the environment is not good for our environment.

So we can conclude that human behaviors greatly impact the environment by overpopulation, pollution, burning fossil fuels, and deforestation.

A primary transcript (immature, non-processed) single-stranded RNA molecule has the following nucleotide composition: 30% A, 20%
Viefleur [7K]

Answer: The nucleotide composition of the double-stranded DNA molecule from which it was transcribed is 30% T, 20% C, 24% G, and 26% A.

Explanation: RNA is transcribed from DNA in the process of transcription. The single stranded RNA is complementary to the DNA template strand. In DNA base pairing, adenine pairs with thymine while guanine pairs with cytosine, this means that in a double-stranded DNA molecule, the total number of adenine is equal to the number of thymine while the total number of guanine is equal to the total number of cytosine.

In RNA, adenine pairs with thymine, guanine pairs with cytosine while uracil pairs with adenine. This means that the total number of thymine on the DNA template strand is equal to the total number of adenine on the RNA strand, the total number of guanine on the DNA template strand is equal to the total number of cytosine on the RNA strand, the total number of adenine on the DNA template strand is equal to the total number of uracil on the RNA strand while the total number of cytosine on the DNA template strand is equal to the total number of guanine on the RNA strand.

RNA strand = DNA strand

30% A = 30% T

20% G = 20% C

24% C = 24% G

26% U = 26% A
