Answer:
A, G2.
Explanation:
G2, the second gap, occurs directly after S phase, the synthesis of new DNA.
The remaining ratio of alleles is about 3:1
<h3>What about alleles?</h3>
- The term "allele" is employed to refer to a gene's alternate form or variants.
- For each autosomal gene, one allele is inherited from each parent, and that we often group the alleles into groups.
- Usually, we ask them as normal, wild-type, aberrant, or mutant alleles.
- For instance, a dominant allele can overcome the characteristics of other recessive alleles;
- These features are what determine an individual's eye and hair color, for instance .
- In this instance, the dominant brown eye alleles outnumber the recessive blue eye alleles.
- Any of two or more genes that may alternately appear at a certain location (locus) on a chromosome is referred to as an allele, also referred to as an allelomorph.
- Alleles may exist in pairs or there could also be many alleles influencing how a certain trait is expressed (phenotype).
- Each gene during a human has two copies (or alleles), one from each parent.
- Alleles significantly contribute to the event of each person's unique traits.
- Alleles are variants of the identical gene with a minor difference in the DNA base sequence.
- An allele may be a gene's variable form.
- Some genes exist during a number of forms, all of which share the identical genetic locus on a chromosome.
- Because each genetic locus in humans has two alleles—one acquired from each parent—they are referred to as diploid creatures.

None; sharks don't have bones, instead, they have strong cartilage, much like what our noses are made up of
Answer:
Red blood cells and blood plasma do not contain DNA. Red blood cells don't have the DNA containing nucleus and mitochondria. Only white blood cells in blood contain DNA. With blood donation, usually most of the white blood cells are filtered out.
Explanation:
because red blood cells don't have the DNA containing nucleus and mitochondria
Answer:
The presence of small amounts of heat-trapping greenhouse gases in the atmosphere warms Earth's surface, resulting in a planet that sustains liquid water and life. c. Changes in climate conditions can affect the health and function of ecosystems and the survival of entire species.Earth and its atmosphere are continuously altered. Plate tectonics shift the continents, raise mountains and move the ocean floor while processes not fully understood alter the climate. Such constant change has characterized Earth since its beginning some 4.5 billion years ago.
