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.

What is important in Hubble's discovery about the red shift in the spectra of galaxies? a. It proves the Big Bang theory. b. It
dedylja [7]

Answer:

c

Explanation:

Hubble's brilliant observation was that the red shift of galaxies was directly proportional to the distance of the galaxy from earth. That meant that things farther away from Earth were moving away faster. In other words, the universe must be expanding.

At what depth(km) would a rock experience temperature of 5500C?
kow [346]

Explanation:

A rock would experience a temperature of 5500°C is about the core which is at a depth of 220km.

But let us use the earth's geothermal gradient to solve this problem.

The geothermal gradient is the rate at which temperature is increasing with depth.

The geothermal gradient 25°C/km

        At 5500°C,

               5500°C x  \frac{1}{25}  \frac{k}{C}  =    220km

But this is not so in nature, there are other heat sources that contributes to increasing temperature with depth such as radioactive heat and frictional heat.

What is the order of the cell cycle
DerKrebs [107]

Answer:

A in explanation

Explanation: The cell cycle is a four-stage process in which the cell increases in size (gap 1, or G1, stage), copies its DNA (synthesis, or S, stage), prepares to divide (gap 2, or G2, stage), and divides (mitosis, or M, stage). The stages G1, S, and G2 make up interphase, which accounts for the span between cell divisions.
