Ans. The carbon cycle.

Carbon cycle can be defined as a series of processes through which carbon compounds are interchanged in environment. It involves uptake of carbon as carbon dioxide into living organisms by the process of photosynthesis to make carbohydrates.  

These carbohydrates are passed along the food chain to consumers. The carbon returns to the atmosphere by respiration (by all animals and plants), burning of fossil fuels, and decay of death organisms.

Thus, the correct answer is option). 'the carbon cycle.'

AleksAgata [21]

Answer:

Option A

Explanation:

Thyroid is primarily caused by lack of iodine but there are other reasons as well that lead to increased size of the thyroid gland. Some of these reason is

a) over- or underproduction of thyroid hormones

b) Nodules in the glans

Some times, due to overstimulation immune system itself attack the thyroid gland thereby producing excess thyroxine and hence causing  the thyroid to swell

Thus, Option A is correct

What kind of mutations were more beneficial ? Why ?
Alex
A mutation is a permanent change in the DNA sequence of a gene. This can be beneficial if the change gives a new function to or improves the function of that gene. 

<span>The above is a definition. But one must really define "beneficial". Some regard it as beneficial if it helps the specific individual who has it. Others would think it beneficial if it produced some survival advantage that insured more descendents for that individual. </span>

<span>It is the difference between a mutation that allowed for greater athletic ability, but a decreased desire for offspring, versus a more moderate athletic enhancement, but a greater desire for offspring. </span>

<span>The small percentage of ways to improve an organism, versus the near infinite ways of harming the organism, mean that most mutations are not going to be beneficial. At best, they will be "inconsequential" - such as a new shade of eye color, or a mole on a section of your skin. </span>

The populist notion of "powers" that can come from mutations is wildly inaccurate. Even assuming a minor power like the ability to see infra red radiation would take thousands upon thousands of mutations over vast amounts of time. A mutation for blindness is far more likely.

<span>It should also be noted that the traditional model of evolutionary theory no longer applies to man. We don't allow changes in our environment, and without such changes, there is no need for one trait more than another to predominate. After all, it is irrelevent that a mutation might allow for greater speed in running, when everyone drives a car.</span>

What is velocity? <br>the one who answer will be marked brainliest ​
bixtya [17]

Velocity is the speed of an object moving in a definite direction. The velocity of an object can be uniform or variable. When an object moving along a straight line at variable speed, we can Express the magnitude of its rate of motion in terms of average velocity.

Average velocity=Initial velocity+Final velocity/2

The SI unit of velocity is m/s.

A woman with type A blood (whose father was type O) has children with a man that has type O blood. Both individuals are heterozy
Fantom [35]

Answer:

Explanation:

A woman with type A blood (whose father was type O) meaning her genotype is AO mates with

Man that has type O blood (OO genotype)

Both are heterozygous for MN blood group and both also heterozygous for the FUT1 gene controlling the synthesis of the H substance (Hh)- which determines the expression of the A and B antigen.

Cross

A O M N H h

O AO OO M MM MN H HH Hh

O AO OO N MN NN h Hh hh

Type A- 1/2 O-1/2 type M- 1/4 MN-1/2 N- 1/4, type H- 3/4 h-1/4

Type A with M antigen:

1/2*1/4*3/4 = 3/32

Type A with M and N antigens:

1/2*1/2*3/4 = 3/16

Type A with N antigen:

1/2*1/4*3/4 = 3/32

Type O with M antigen:

1/2*1/4*3/4= 3/32

Type O with M and N antigens:

1/2*1/2*3/4 = 3/16

Type O with N antigen:

1/2*1/4*3/4 = 3/32.

The 3/4 value comes from the expression of Hh-3/4 (this determines if the A and B Angie will be expressed).
