Answer:

<u>the bottleneck effect</u>

<u />

Explanation:

Genetic drift has an important impact on the small populations. mutations, which are spontaneous heritable changes in the genetic code, made up of DNA. Here, mutations accumulate over time in a group, modifying the distribution of alleles or various forms of a gene. Natural selection may result in a loss of diversity in a population called genetic drift; one trait's allelic frequency rises while others become less prevalent. Typically such differences exist because of occurrences of mutation and recombination.

Some mutations or alleles may become extinct from the population.

<u />

Variants of a gene accumulate and are transmitted across generations; the frequencies of these occurrences are altered and become more stable in genetic drift- they become genetically distinct and may eventually form a new species after isolation. This may be further compounded through other  phenomena such as the founder effect where a group separates and genetic diversity decreases; and the bottleneck effect where barriers to reproduction or the die-off a population increases genetic drift.

Why are groups of small cells better than one large cell at moving material in
quester [9]

Answer:

C. They have a greater surface-to-volume ratio.

Explanation:

Because these smaller cells can access and pass through the membranes of the other cell membranes and permeable coverings easily and voluntarily unlike larger cells. It is also efficient for these smaller cells to penetrate and travel, delivering and transporting goods and materials such as nutrients, oxygen and waste throughout the body without consuming enough energy and conserving lesser space.

For simple reasons, they are faster, more efficient and consumes little space, and most especially depletes lesser energy. So, many small cells have more surface area than one large cell.

The filtrate formed by the nephrons in the kidney is NOT urine. The filtrate is first refined and concentrated by the processes
dexar [7]

The filtrate is first refined and concentrated by the processes of <u>reabsorption and secretion</u>, which form the urine that leaves the body.

<h3>Process of filtration in kidney:</h3>

The glomerulus filters your blood, and the tubule restores necessary substances to your blood while removing waste. The glomerulus is nestled within a region of the kidney called the Bowman's Capsule. This is where filtration occurs. The high pressure causes some substances to pass through the capillary walls when blood is forced through the tiny capillaries. The walls serve as a filter or sieve. This is how the function of the nephron. A glomerulus filters your blood, while a tubule restores necessary substances to your circulation while removing extra waste. Each nephron has both of these functions.
