6 0

Answer: The correct answer is -

It prevents harmful substances from entering a cell.

Explanation:

Cell membrane is a selectively permeable, protective layer that is present surrounding the cytoplasm of all cells of living organisms. It allows the entry and exit of only certain substances

It does not allow the harmful substances to enter inside the cell and at the same time, the useful substances to exit the cell. Due to this, it is also known as selectively permeable membrane.

Thus, last option is the right answer.

You cross two red griffins with blue eyes and produce offspring that are: red with blue eyes, red with green eyes, white with bl
sergejj [24]

Answer:

The reason for the offspring to present these genotypes is that during the formation of the gametes, the alleles separate and are inherited independently, therefore they can generate several different phenotypic combinations.

Explanation:

In order for an offspring to present very different phenotypes, as shown in the question above, it is necessary that the two red griffins with blue eyes that were crossed are heterozygous. Thus it will be possible for the offspring to present a wide variety of phenotype, according to Mendel's second law.

Mendel's second law is called the Law of segregation. This law explains that the alleles (which determine the characteristics of individuals) are separated in the formation of gametes and inherited by the offspring of a cross independently, and can generate different combinations of phenotypes, when the parents of a cross are heterozygous.

Why does diversity increase as height above land increases​
wolverine [178]

Biodiversity rises with altitude initially before falling with height beyond that. Up until it reaches a diversity peak at about 1 300 to 1 800 m.

  • The biodiversity increases at higher geographical locations because There are more hiding locations. They are better for crop growth. They frequently include more than one kind of habitat.
  • As latitude or altitude change, so does biodiversity. As we descend from high to low elevations, the diversity increases (i.e., from poles to equator).
  • While the environment is harsh and plants have a brief growing season in the temperate region, tropical rain forests provide year-round growth-friendly circumstances.
  • This enables the emergence and expansion of several species. On a mountain, there is an initial increase in species diversity after which there is a decline in species variety as you go up in elevation.
  • At higher elevations, temperature drops and seasonal variations increase, which significantly diminishes.
