Answer:

The answer would be C. hydrogen

Explanation:

There is basically no hydrogen in the atmosphere as it barely makes up 0.0001 % of the atmosphere

Hope this helps ;) and if it does i would appreciate for this to be the brainliest answer =).

The correct answer is letter c. hydrogen. Hydrogen is not commonly found within the Earth's atmosphere, but it is found on parts of the water. Hydrogen's pure form is rarely to be found on Earth's atmosphere. Oxygen and Nitrogen are two gases that makes up the Earth's atmosphere.

Which of the following is not a natural cause of extinction?

dedylja [7]

Answer:

Introduction of Non-native species would be the answer. ( B )

Explanation:

Now let's break it down.

A. Competition due to overpopulation

Competition due to overpopulation, as competition of resources rises, species will fight among each other, and slowly, population will go down. But I don't see the reason of why it would cause an extinction... perhaps a decrease of population. See, once populations starts decreasing, resources will increase. And ONCE resources increase, populations starts increasing, and there goes competition. Resources decreases, populations decreases, and the whole process repeats. So I'm not quite sure whether it will cause extinction of a species.

B. Introduction of Non- native species.

So what does it mean by Non-native species?

It means that species that have no effect and doesn't exist in the ecosystem. So that will definitely not affect the population whatsoever.

C. Catastrophic Events

Well, common sense. Many people died of tsunamis, tornado and other natural disasters every year. Too many disasters can cause the population to cease.

D. Disease

This we can relate, especially the Coronavirus. Many humans died of the deadly virus. Same goes to animals. If a disease gets too deadly, population will decrease and drive the species to extinction.

So, the Answer would be B.

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.

How do bacteria maintain their internal ph despite the ph of the environment in which they grow?

ipn [44]

The answer to this question would be: by producing buffer

The pH of optimal growth of bacteria might be different. Some bacteria can grow in an acid condition called acidophile, other live in base condition called alkaliphiles and the rest live in neutral pH condition called neutrophiles. The bacteria can maintain their internal pH by producing acid, base or buffer. If the surrounding pH is too acid, the bacteria can reduce the H+ concentration by producing base. If the condition is too alkali/base, the bacteria can produce acid by doing fermentation.
