according to island biogeography theory, the highest numbers of species would be found on islands that:
Answers
According to island biogeography theory, the highest numbers of species would be found on islands that are large and close to the mainland.
Island biogeography theory is a theory that explains the relationship between island size and distance from the mainland to the number of species found on an island. It was developed by Robert MacArthur and Edward O. Wilson in the 1960s. The theory suggests that larger islands have higher species richness than smaller islands, and islands closer to the mainland also have higher species richness than islands that are farther away.
The explanation behind the theory is that larger islands have more habitat diversity, which can support more species. Also, islands closer to the mainland are more likely to receive immigrant species from the mainland and have lower extinction rates than those that are farther away.Therefore, according to the island biogeography theory, the highest numbers of species would be found on islands that are large and close to the mainland.

In generation 1 one parent is affected by the gene mutation and one parent isn't. In generation 2 all three children are affected by the Gene mutation what can conclude about this gene mutation
Answers
Answer:
An autosomal dominant mutation
Explanation:
A situation where only one parent is affected by the gene mutation and the offspring also gets affected means the offspring only need to inherit one copy of the mutation in a dominant form to become affected unlike the autosomal recessive form where 2 copies (1 each from both parents are needed to become affected)
Thus, the gene mutation is said to be dominant. It is also autosomal because it affects both male and female offspring. Thus, the gene mysterious is said to be autosomal dominant.
Another characteristic is that it does not skip generations. Once a generation is skipped, that is the end.

Short-chain triglycerides found in foods such as butterfat molecules in milk are split by a specific enzyme in preparation for absorption. Which of the following enzymes is responsible?
A. chymotrypsin
B. lipase
C. amylase
D. pepsin
Answers
The enzyme responsible for splitting short-chain triglycerides found in foods such as butterfat molecules in milk is lipase. So the correct answer is option B.
Lipase is an enzyme that is produced by the pancreas and secreted into the small intestine where it helps to break down dietary fats into smaller molecules that can be absorbed by the body. Lipase works by hydrolyzing the ester bonds that hold the fatty acids in the triglyceride molecule. This process releases the fatty acids, which can then be transported across the intestinal lining and into the bloodstream, where they can be used as an energy source by the body's cells. While lipase is responsible for breaking down most dietary fats, other enzymes such as amylase, pepsin, and chymotrypsin are involved in the digestion of carbohydrates, proteins, and other nutrients.

In an animal, which part of the cell is responsible for keeping viruses out?
Answers
Answer:
here's your answer
Explanation:
Once attached to a host cell, animal viruses may enter in a variety of ways: by endocytosis, where the membrane folds in; by making channels in the host membrane (through which DNA or RNA can be injected); or, for enveloped viruses, by fusing with the membrane and releasing the capsid inside of the cell.In an animal cell, the lysosome is an organelle of the cell that is responsible for destroying the virus. The virus can enter the cell via endocytosis, but the lysosome can degrade and destroy it to protect the cell.
What is the function of the immune cell?Immune cells such as neutrophils, macrophages, and others play a role in protecting the body from foreign harmful pathogens. They have specific structures for doing so.
Because not all body cells have MHC II or toll-like receptors, cells have different organelles to protect themselves. Cells have lysosomes within them. Lysosomes have an acidic environment that can degrade viral proteins.
When the virus is phagocytosed by the cell, it combines with the lysosome. The lysosome degrades the virus with the help of hydrolyzing enzymes and throws it out of the cells. These are collected by other cells.
Hence, the lysosome of the cell degrades the virus and keeps it out.

The allele that causes an altered form of hemoglobin (Hb) occurs in all human populations as a result of mutation.

Which process of evolution is likely responsible for the allele being in such high numbers in these populations?
Answers
The allele that causes an altered form of hemoglobin (Hb) occurs in all human populations as a result of mutation. In some populations, this allele has increased in frequency because it confers some resistance to malaria.
Which process of evolution is likely responsible for the allele being in such high numbers in these populations?The natural selection process of evolution is responsible for the allele being in such high numbers in these populations. The evolution of human populations has been greatly influenced by various factors, one of which is the increased frequency of the allele that causes an altered form of hemoglobin in populations with malaria prevalence.The allele that causes an altered form of hemoglobin is a mutation that confers some resistance to malaria. In areas where malaria is prevalent, individuals with this allele have a selective advantage over those without it. This selective advantage results in the increased frequency of the allele in populations that have malaria as compared to those that do not have malaria.In areas where malaria is not prevalent, the selective advantage of the allele is lost, and the frequency of the allele is lower.
Therefore, the frequency of the allele is not uniform across all populations. This is because the natural selection process favors the survival and reproduction of individuals with certain traits that are advantageous for survival and reproduction in specific environments.The natural selection process favors traits that allow individuals to survive and reproduce in their environment. In this case, individuals with the allele that causes an altered form of hemoglobin are better adapted to malaria-prone environments. As a result, the allele is likely to be in high numbers in these populations. Therefore, natural selection is responsible for the allele being in such high numbers in populations with a prevalence of malaria.

A 10.0 cm3 sample of copper has a mass of 89.6 g. What is the density of copper?
Answers
Answer:
\(\boxed {\boxed {\sf d=8.96 \ g/cm^3}}\)
Explanation:
Density can be found by dividing the mass by the volume.
\(d=\frac{m}{v}\)
The mass of the copper is 89.6 grams.
The volume is 10 cubic centimeters.
\(m=89.6 \ g\\v= 10 \ cm^3\)
Substitute the values into the formula.
\(d=\frac{89.6 \ g }{10 \ cm^3}\)
Divide.
\(d=8.96 \ g/cm^3\)
The density of copper is 8.96 grams per cubic centimeter.
