The circulatory and skeletal systems work together in the following way: skeletal system produces cells in the bone marrow while the circulatory system transports cells where they need to go (option A).

<h3>What is skeletal and circulatory system?</h3>

Skeletal system is the system that works as a support structure for your body. It gives the body its shape, allows movement, makes blood cells, provides protection for organs and stores minerals.

Circulatory system, on the other hand, are parts of an animal body comprising the heart, veins, capillaries and arteries. It circulates blood and lymph through the body.

According to the above description of both systems, the skeletal system produces blood cells in the bone marrow while the circulatory system transports these cells.

How will the change in pH impact the functioning of cells? (Hint: Explain which biomolecules and what types of bonds in these bi

Effectus [21]

Answer:

A change in pH will cause many cellular processes to be disrupted because they affect the biomolecules (protein and nucleic acid) responsible for these processes.

Explanation:

pH refers to the degree of acidity or alkalinity. In a cell, the structures and processes that occur in them are impossible without the biomolecules, which are carbohydrate, protein, lipids and protein.

However, unfavorable conditions like a change in pH can cause the structure of some of these biomolecules to be affected. Proteins are made up of amino acids, which gives them their shape that is peculiar to their functioning. Also, nucleic acids such as DNA are composed of nucleotides responsible for their functioning.

A change in pH will cause the bonds of the protein to be disrupted, hence altering its shape and ultimately its functioning. Likewise, the hydrogen bonds in the DNA will be broken in the presence of a high pH causing the DNA to be dysfunctional.

When these biomolecules are affected, the vital functions that they perform in a cell, which is key to the cell's survival are disrupted) are likewise affected. Therefore, the cell is affected negatively.

TRUE or FALSE. | There is a gravitational attraction force between you and this computer.

kolbaska11 [484]

Answer:

true

Explanation:

Since gravitational force is inversely proportional to the square of the separation distance between the two interacting objects, more separation distance will result in weaker gravitational forces. So as two objects are separated from each other, the force of gravitational attraction between them also decreases.

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

Juli2301 [7.4K]

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.

Population size between the 1st and 2nd years

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.

Population size between the years 2, 3 and 4

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.

Population size the fourth year

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.

Population size after the fourth year

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.

1) During what year did the foxes most likely arrive?

During the fourth year

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

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