Which part of the nervous system would carry messages from a person's sore knee to alert him or her to stop running and rest?

Firstly, the message would be carried by the peripheral nervous system which is responsible to take all information from outside the central nervous system (brain and spinal cord) to it. Within this peripheral nervous system, the part of it that would be used is the somatic nervous system<span> which is</span><span> associated with voluntary control of the body through </span><span>skeletal muscles, allowing him to stop running and rest because he/she felt his/her knee was sore.</span>

B. A family of foxes arrived on the island after the rabbits were released. No

The carrying capacity is affected by dense dependent and dense independent factors. 1) During the fourth year. 2) Negative impact. K decreased from 200 to 100 rabbits.  

<h3>What is carrying capacity?</h3>

Carrying capacity -K- is the capability of the environment to support a growing population.

It is a constant that coincides with the population size at which natality and mortality rates are equal. This is the equilibrium point.

Commonly, environments have limited resources, and as the population grows, resources are consumed faster, leading to an increase in the competition rate.

Per capita growth rate decreases as population size, N, increases.

  • If the N < K, the population can still grow.

• When N approximates to K, the population's growth speed decreases.

• When N = K, the population reaches equilibrium,

• When N > K, the population must decrease in size because there are not enough resources to maintain that size.

The carrying capacity might be affected by limiting factors, which might be

  • density dependent (for example, competition, predation, etcetera)
  • density independent. This last case refers to dense-independent factors, among which we can mention human impact or natural disasters (fires, volcanic eruption, flooding).

In the exposed example, when referring to rabbit's carrying capacity, we can assume it is limmited by intraspecific competition and by predation.

  • <u>Population size </u><u>between the 1st and 2nd years</u>

At first we can see that during the first two years, the number of rabbits increased until it was a little bit over 200 individuals.

  • <u>Population size </u><u>between the years 2, 3 and 4</u>

During the second, third, and fourth year, the number of rabbits was kept around 200 individuals, which leads us to assume that K = 200 rabbits.

  • <u>Population size </u><u>the fourth year</u>

However, in the fourth year, there was a sharp decrease in the number of rabbits. Probably this event was due to the arrival of foxes (predators) on the island.

  • <u>Population size</u><u> after the fourth year</u>

In the presence of foxes, the number of rabbits varied around 100 (K = 100).

According to this information, we can assume that only intraspecific competition (related to resources) had a significant role during the first years.

But with the foxes' arrival, the rabbits' carrying capacity decreased from 200 to 100, meaning that, during the following years, predation strongly influenced the rabbits' carrying capacity.  

<em>1) During what year did the foxes most likely arrive? </em>

During the fourth year

<em>2) How did the arrival of the fox family impact the carrying capacity of the rabbit population on this island? </em>

Foxes had a negative impact on the foxes' carrying capacity. It decreased<u> from k = 200 to k = 100 </u>since the foxes arrival to the island.

What role does the MutL protein play in DNA repair? (5 POINTS) It performs a proofreading function, similar to DNA polymerase, a
Zinaida [17]

Answer:

It recognizes and binds to a pair of "mismatched" nucleotides, preventing their translation.

Explanation:

Mut L protein is involved in mismatch DNA repair. MutL protein is complexed with MutS protein and the MutL-MutS complex recognizes all the mismatched base pairs present in the newly formed DNA strand. The complex can not recognize the "C-C" pairs. MutH protein joins the complex.

The MutH protein also has a site-specific endonuclease activity and cleaves the unmethylated DNA strand towards the 5' end of the guanine base in the GATC sequence to mark the strand for DNA repair. In this way, MutL protein, along with MutS and MutH proteins mark the mismatched DNA bases for repair so that they are not translated into a faulty protein.
