Which best explains the importance of a selectively permeable cell

magine you are trying to determine the phenotypic ratio of hair color. Brown (B) hair color is the dominant trait and blonde (b)

skad [1K]

Answer:

1:1 (brown:blonde)

Explanation:

Brown hair color (B) is dominant over blonde hair color (b).

Heterozygous parent will have the genotype Bb

Homozygous recessive parent will have the genotype bb.

Crossing hetezygous parent with homozygous recessive parent:

Bb x bb

Progeny: Bb, Bb, bb, and bb.

2 Bb brown hair

2 bb blonde hair

Phenotypic ratio = 1:1 (brown:blonde)

The correct answer is 1:1 (brown:blonde).

During the Human Genome Project, scientists created a gene map showing the relative location of each known gene on every human c

Arlecino [84]

Answer:

Approximately 20,500 genes

Explanation:

The Human Genome Project (HGP) was a 13-year international research effort aimed at determining the entire DNA sequence of the human genome. The HGP was launched in 1990 and completed in April 2013. This project helped to identify and physically map all the genes of the human genome. The sequence obtained from the HGP has been a very useful point of reference in order to identify and characterize mutations associated with genetic disorders. The HGP predicted approximately 20,500 genes (each of them produces an average of three proteins), which are distributed in the 23 pairs of chromosomes in the cells of our body.

Adapt extinct mutation

lisabon 2012 [21]

That organism will survive in the future which adapt themselves according to the environment.

<h3>What is fitness?</h3>

Fittest is the term describes living things that are best suited to their environment.

Species that survive are the ones that adapt, make or meet changes.

Florida has a rich fossil record spanning from the Eocene to recent times. Florida fossils are often very well preserved.

Two examples of land animal fossils found in Florida are the giant sloth and the saber-tooth tiger.

Some animals unable to adapt to the changing environment became extinct .

Living things mutate over time to meet their changing environment.

This biologist, Darwin, studied evolution in the 1800s.

The glyptodont was a giant, armadillo-like animal with a spiked tail that once lived in Florida.

The Origin of Species is a book written in 1859 about natural selection.

Nature selects the fittest for survival because they have useful traits.

Changes may occur in animals due to changes in the sequence of base pairs in their DNA, and this is known as a mutation.

Oldfield mice show variation in the color of their fur.

The survival of the light-colored old field mice on Florida's Gulf Coast is an example of the process called adaptation.

Evolution is a controversial theory that has survived much criticism.
