Which of these is a function of the blood? a) carry oxygen to the cells b) carry wastes to be removed c) both are functions of b
damaskus [11]

Answer:

c) Both are functions of blood, that is, to carry oxygen to  the cells and also remove wastes from the body.

Explanation:

Blood is a form  of connective  tissue and is made up of red blood cells,  white blood cells, platelets and blood plasma. The red blood cells contains a metallo-protein structure known as hemoglobin. This hemoglobin binds to the oxygen and carry them to the cells and the tissues for proper functioning of them. The waste products like carbon dioxide is carried by the blood from the body tissues to expel it out from the body.

Will earth run out of water?
Kazeer [188]

<u>While our globe may never run out of water as a whole</u>, it's crucial to realize that pure freshwater isn't always available where and when humans require it. In fact, only six countries contain half of the world's freshwater. Over a billion people do not have access to adequate safe, clean water. Water scarcity will afflict the entire planet by 2040 unless water use is significantly decreased. "If we keep doing what we're doing now, there will be no water by 2040."

Which of the following statements about renewable energy resources is true?
Brilliant_brown [7]

The statement that is true about renewable energy resources is that there are endless supplies of all renewable energy resources (option B).

<h3>What is renewable energy resource?</h3>

Renewable energy is the energy that is collected from renewable resources such as;

  • wind power
  • hydropower
  • solar energy

A renewable resource is that natural resource that is replenished by natural processes at a rate comparable to its rate of consumption by humans or other users.

This suggests that renewable resources have an unlimited supply and will likely not be exhausted. This is unlike the non-renewable counterparts like crude oil, gas etc.

Therefore, the statement that is true about renewable energy resources is that there are endless supplies of all renewable energy resources.

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.

  • <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.
