How do cells get energy to perform their necessary functions

1 answer:

7 0

Cells get energy to perform their necessary functions by taking in nutrients from food. During the digestive process, nutrients from food are broken down and used to synthesize sugar, or glucose, molecules.

1. Which type of clouds can you always expect to signal fair weather: cirrus, stratus, or cumulus?

padilas [110]

The most suitable option for the first question is definitely stratus clouds which usually stratch over the sky creating overcasts.
The next one should be nimbus, as they dark and usually help to predict the storm.
And the last one cumulonimbus that point on thunderstorms and so on.

How are humans responsible for environmental pollution

Reptile [31]

Answer:

Humans are responsible for the environmental pollution in many ways . Some of the points are as follows :

1 ) People throw the wastes wherever they like instead of using dustbins .

2 ) The various types of gases from the industries which harms the nature .

3 ) Cutting off the trees . ( people can cut but also must plant a new one )

4 ) Farmers using different chemical substances in high amount in the crops .

5 ) Burning plastics , tires etc .

This was my way to answer the question , if you need then you can write in paragraph .

let me know if its incorrect . :-)

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.

DNA has two strands. If the sequence of nucleotides of one strand was known, is it possible to use that information to determine

yanalaym [24]

It is possible to use the information of the nucleotide sequence of one strand to determine the sequence of the other strand.

Deoxyribonucleic acid (DNA) is a biological molecule with two strands. Each strand is made up of a sequence of nucleotides. The DNA nucleotides are Adenine (A), Cytosine (C), Guanine (G) and Thymine (T).

In a DNA molecule, Adenine forms an hydrogen bond with Thymine i.e. A-T, while Guanine forms an hydrogen bond with Cytosine i.e. G-C.

Therefore, it is possible to use the information of the nucleotide sequence of one strand to determine the sequence of the other strand. For example, a strand with ATGCGTACGAT will form the following sequence: TACGCATGCTA
