Answer:
Genetic drift
Explanation:
Genetic drift describes random fluctuations in the numbers of gene variants in a population. Genetic drift takes place when the occurrence of variant forms of a gene, called alleles, increases and decreases by chance over time. These variations in the presence of alleles are measured as changes in allele frequencies.
A random change in allele frequencies over time is known as "genetic drift." Hence, due to this, the allelic frequencies alter in a population over time.
What is genetic drift?A genetic drift changes the gene pool of a particular population. It is significant in a small population. Many factors such as migration, birth, and death affect the genetic pool. Some new genes are added to the gene pool as a result of genetic drift, while others are permanently lost. Increases in one allelic frequency replace the other allele.
In a small population of 20 animals, black skin is dominant over white. 12 are homozygous for black skin, 5 are heterozygous for black skin, and 3 are recessive and show white skin. If any natural calamities happen that destroy the white animals, then this allele will disappear from the population. After many generations, only black-skinned individuals will appear.
Hence, a random change in allele frequencies over time is called "genetic drift."

what is the function of the water monitor lizards claws
Answer:
Claws. These strong, curved claws can tear flesh and inflict fearsome wounds. Water Monitors eat only meat and sometimes tackle prey nearly their own size. Claws may allow the Arboreal taxa to physically separate themselves from the larger monitors of the savannah by living in trees, eliminating them as competition and potential predators.

How many solutions does the equation 4x + 2(x-5) = 3(2x - 4) have? Write down the final form as well as if it has no solution, exactly one solution, at least two solutions, or infinitely many solutions. please help me
Answer:
0 = -2, hence no solution.
Explanation:
4x + 2(x-5) = 3(2x-4)
4x + 2x - 10 = 6x - 12
6x - 6x = -12 + 10
0 = -2

Answer: essay part
Explanation: I couldn't list eight products but here is my essay on a wool scarf. may not be the best but here:
_________________________
I chose a wool scarf.
wool is made mainly from the coat of a sheep, however, in other cases they can come from a alpacas, goats, and rabbits.
Sheep that have been domesticated and kept as livestock are frequently seen roaming around farms and other green areas. However, you can find wild sheep throughout North America, Central Europe, and the Middle East. Anywhere from mountains, deserts, or a sizable area can be home to sheep, depending on the species.
Sheep are naturally adapted to upland environments and harsh weather, which enables them to flourish where other mammals might find it difficult to survive. In the Middle East, Asia, Central Europe, and North America, where they live in steep hilly terrain, wild sheep are most frequently encountered.
Sheep are extremely reliant on their owners; they rely on them for food, protection, and health maintenance. Additionally, sheep rely on one another for safety
Wild sheep are susceptible to habitat destruction, poaching, and trophy hunting. Sheep can be found at research facilities and medical colleges where they are exploited for brutal tests. Sheep farmed for their wool, meat, and milk sometimes live in subpar conditions and lambs may even have their tails painfully "docked."

Answer:
During the Calvin cycle, carbon dioxide is reduced to drive the formation of sugars.
During the process of photosynthesis, a set of chemical reaction that occurs in the chloroplast is known as the Calvin cycle, which is light independent.
Photosynthesis reaction can be divided into two stages that are the light reaction and the Calvin cycle, in the first stage light energy converted to the chemical energy and the second stage use the products of light reaction to produce sugar.

which human organ is responsible for detoxifying the blood from toxic substances?
The human organ in charge of detoxifying the blood, in addition to a variety of other functions, is the liver.
The liver is the largest solid internal organ of the human body. It is located in the abdominal region. To be precise in the upper right-hand side of the abdomen, just below the diaphragm. The liver has a variety of functions including:
Enzymatic functionsProduction and excretion of bileExcretion of substances (eg hormones)Storage of glycogen and nutrientsDetoxification of bloodamong a few others.
The liver acts as the primary filter for the body's blood. It filters out toxins, breaks down chemicals through enzymatic processes, and removes alcohol from the blood. These processes create waste products known as urea and bile, which are excreted by the liver to be removed from the body by other organs.
