Answer:

0%

Explanation:

This is a typical monohybrid cross involving a single gene B.

Both parents are purebreeding or homozygous i.e. have identical alleles for the specified trait. Hence, in a cross between the two, all the offsprings will be heterozygous (Bb) i.e. possess different alleles for the trait (See attached image).

N.B: A genotype is the genetical make up of an organism.

Since the genotypes of all the possible offsprings will be Bb, there is none that will possess the same genotype as any of the parent. Hence, the percentage is 0% i.e. 0/4 × 100

How can point and frameshift mutations contribute to biodiversity of Earth? Explain your<br> answer.
Blizzard [7]

Answer:

<u><em>These mutations form new alleles that increase genetic variation in a population. This variation may lead to new species which increases biodiversity.</em></u>

Explanation:

Mutations are randomly occurring modifications that exist within the genetic code, leading to replication errors in DNA. DNA molecules are long-chain, helical macromolecules that store genetic material. They consist of different monomer sequences called nucleotides. In a reading frame, which contains instructions for protein production, they shape base pairs and codon sequences.

Single nucleotide polymorphisms are normal, as silent mutations, which sometimes result in no changes in amino acids. Some mistakes add a random nucleotide (SNP) in point mutations resulting in new alleles.

Frameshift mutations occur from nucleotide insertions or deletions that are not divisible by 3. This results in the codon requiring more or fewer nucleotides which disrupt the reading frame, resulting in a separate protein translation.

Explain in your own words what caused Pangea to separate and why we don't worry about earthquakes in Florida.
frozen [14]
There are no plate boundaries under Florida. The plate movement that caused Pangea to separate is due to convection currents that roll over in the upper zone of the mantle.

How will the level of carbon in the atmosphere change if humans do nothing to
snow_lady [41]

Answer:

Option B.

The level of carbon in the atmosphere will decrease if humans do nothing to cycle.

Explanation:

  • The carbon cycle which is also known as the bio Geo chemical cycle is the process that involves the exchange of carbon between the layers: biosphere, geosphere, hydrosphere, and atmosphere of the Earth.
  • In this cycle process, the carbon dioxide is eliminated from the atmosphere primarily by the process called as the photosynthesis process (which occurs in green plants) and get into the terrestrial and oceanic biospheres by dissolving into rainwater.
