Answer:
When it stands the test of time and is supported by many experiments.
The correct option is (a) 2 → 4 → 1 → 3
A change occurs in the environment. → Poorly adapted individuals have decreased survivorship. → Well-adapted individuals leave more offspring than do poorly adapted individuals. → Genetic frequencies within the population change.
<h3>
What is genetic variation in population?</h3>
- The presence of various alleles, or different gene versions, within a population indicates genetic variety.
- If there is genetic variation, then everybody in the population will have various genotypes depending on the alleles they carry.
- Genetic loci that have many alleles are said to be polymorphic. Human characteristics like blood type and eye color, for instance, are polymorphic.

It is safe to assume that the eastern kingbird will have a <u>type 2 </u><u>functional response </u><u>to an increase in </u><u>prey abundance</u><u>.</u>
The functional response, in ecology, is a data-based description of the behavior of certain animals' consumption rates in response to a change in prey density. This can be of three kinds:
- Type 1: An increase in consumption
- Type 2: A decrease in consumption
- Type 3: Decreased consumption, followed by a quick increase.
The Eastern kingbird is likely to follow a <u>type 1 </u><u>functional response</u> to the presence of more prey. The reason for this, aside from it being the most common response, is that the eastern kingbird consumes insects, which do not provide a great amount of energy, in a way that consumes much energy. Therefore it is logical to assume that the kingbird will consume more prey to better sustain its rigorous feeding habits.

In addition to chloride, there are other negatively charged molecules in plasma. The extra sodium restores the balance of the overall negative charges.
So this is how plasma is electrically neutral.
<h3>The makeup of bodily fluids:</h3>
- High levels of sodium, chloride, bicarbonate, and protein can be found in the plasma.
- High levels of salt, chloride, and bicarbonate but a relatively low level of protein can be found in the IF.
- The ICF, on the other hand, contains higher levels of protein, phosphate, magnesium, and potassium.
<h3>What occurs when the
plasma Na+ content rises?</h3>
- Although the plasma sodium concentration does not provide any information regarding the volume of extracellular fluid, it does allow for an assumption regarding intracellular volume.
- A rise in plasma sodium (plasma osmolality) causes water to be drawn out of the cell, which causes the intracellular volume to decrease.
<h3>Why does
plasma have a
higher sodium content than
chloride?</h3>
- In plasma, sodium predominates over chloride.
- In addition to chloride, there are other negatively charged molecules in plasma.
- The extra sodium restores the balance of the overall negative charges.
