Nitrogenous bases basically pairs with bases that are complementary. The correct option is B.
What are nitrogenous bases?Nucleobases, also referred to as nitrogenous bases or purely bases, are nitrogen-containing biological molecules that form nucleosides, which are then constituents of nucleotides, all of which are the basic building boxes of nucleic acids.
A set of 5 nitrogenous bases is used to build nucleotides, which then in results nucleic acids such as DNA and RNA.
These bases are critical because their sequencing in DNA and RNA is how information is stored.
A base pair in DNA are complementary to each other. Under normal conditions, the nitrogen-containing bases adenine (A) and thymine (T) pair, whilst also cytosine (C) and guanine (G) pair.
The structure of DNA is formed by the binding of these base pairs.
Thus, the correct option is B.

In 2019, Iceland recorded 7890 births and 123 deaths per week. What was the Population Growth Rate for Iceland?
Answer:
The Population Growth Rate was 403884 in 2019
Explanation:
Lets first calculate how many total new lives per week iceland had.
Births - Deaths = New Lives
7890 - 123
=
7767
So we have 7767 lives that are new every week.
So like a 7767 growth.
But I think the growth rate is yearly.
So with 52 weeks in a year lets multiply the amount of weeks with the new lives weekly.
7767 x 52
=
403884
The Population Growth Rate was 403884 in 2019.
I hope this helps.

In the scenario above, Red hair (R) is dominant to blonde hair (r). If two parents are
heterozygous for red hair, what percentage of their offspring will have red hair and what
percentage will have blonde?
Answer:
75% of the offspring will have red hair and 25% will have blonde hair.
Explanation:
Since red is dominent but heterozygous it will be represented like Rr. Since both parents have that put it on a punnet square to get 75% red and 25% white.

Negative feedback: If the body temperature is high, the rate of perspiration (sweat) should
A. increase
B. decrease
Answer:
I believe it would decrease
Explanation:
The high temperature will be detected by sensors—primarily nerve cells with endings in your skin and brain—and relayed to a temperature-regulatory control center in your brain. The control center will process the information and activate effectors—such as the sweat glands—whose job is to oppose the stimulus by bringing body temperature down.
