Answer:
Controlled burns can minimize insects and disease and improve the habitat for threatened and endangered animal species. Prescribed burns provide key nutrients to soil, which help trees and vegetation flourish. These controlled forest fires also open up the tree canopy to allow sunlight into the forest
Explanation:
Diffusion is important to the cell because it is the process by which useful molecules enter the cell and waste products removed from the cell.
Without diffusion, cells and tissues of the body can not get important nutrients and gases for survival and would die.
An example is the eye. The eyes lack a great number of blood vessels (which carry oxygen that diffuses into cells) and must have an extra supply of oxygen. The atmosphere provides the extra needed oxygen which is taken up into the cells of the eye by diffusing through the cornea and thus the eye is kept functioning. If this does not happen , the eye would dry out.

"In humans, the allele for dimples (D) is dominant to
the allele for no dimples (d). at another gene locus, the allele for broad
eyebrows (B) is dominant to the allele for broad eyebrows (b)."
Man: Heterozygous for both genes means DdBb
Woman: no dimples, and heterozygous for slender eye-brows
means ddBb

Interpretation: anywhere that has a capital letter has the
dominant trait.
Dimples+Broad eyebrows : 6 cases out of 16 (3/8=37.5%)
Dimples+slender eyebrows: 2 cases out of 16 (1/8=12.5%)
No dimples+Broad eyebrows: 6 cases out of 16 (3/8=37.5%)
No dimples+slender eyebrows: 2 cases out of 16 (1/8=12.5%)
Answer:
B
Explanation:
They can be dominant or recessive.
