Answer:
Individuals with different alleles for a single trait are classified as <u>heterozygous.</u>
Explanation:
Zygosity is defined as the degree of similarity of alleles for a given trait. Alleles are the variations in the DNA sequence of a gene, that varies from one organism to another.
A diploid organism is homozygous at a gene locus, when both the alleles for a single trait are same. Whereas, a diploid organism is heterozygous at a gene locus, when both the alleles are different for a single trait.
Answer:
they give the lungs a really big surface area. they have moist, thin walls (just one cell thick) they have a lot of tiny blood vessels called capillaries.
The walls of the alveoli are only one cell thick. This makes the exchange surface very thin - shortening the diffusion distance across which gases have to move. Each alveolus is surrounded by blood capillaries which ensure a good blood supply.Adaptations of the alveoli:
Thin walls - alveolar walls are one cell thick providing gases with a short diffusion distance. Moist walls - gases dissolve in the moisture helping them to pass across the gas exchange surface. Permeable walls - allow gases to pass through.
Explanation:
Have great day
Answer:
its would be brown because it is more dominant
Answer:
it is accepted that cells contain DNA in chromosomes and RNA in the nucleus and cytoplasm, but only in the modern cell theory. the classical cell theory does not include this. but using either classical or modern theory, it is false that all cells have DNA surrounded by a nucleus.
