<span>The answer is letter D. Annual rings in woody stems are caused by an increase in rings of the secondary xylem. During the fall, the secondary xylem develops dense woods. Thin woods are develop during the spring which marks the formation of ring on its annual growth.</span>
Answer: Using H as the allele,
Father - Hh or hh
Mother - Hh
Explanation:
Both parents must have at least one recessive gene to pass down to the hemophiliac woman. The mother does not have the disorder, so she must be heterozygous. No information is given on the father, but he must have passed down at least one recessive allele, so he cannot be homozygous dominant.
This individual is heterozygous dominant for that height trait.
Explanation:
In Mendelian Genetics the letters in uppercase are for dominant traits and those in lower case are for recessive trait.
An individual has 2 alleles for a gene one from either parent. The dominant allele express the phenotype according to the law of dominance. Individual could be either heterozygous that is both the dominant and recessive traits' allele are present in its gene or homozygous dominant in which both the alleles are dominant.
eg: GG (dominant homozygous)
Gg (Heterozygous dominant)
The individual with genotype Gg for a height will have dominant allele expressed which will mask the effect of recessive gene. The phenotype will be of dominant trait.

Answer:
c) succession
Explanation:
Succession, in Ecology, refers to the series of changes that occurs to the structure of a biological community. Succession is of two types namely: primary and secondary succession. Primary succession is the colonization of an area for the first time by organisms called PIONEER SPECIES.
Secondary succession involves the recolonization of an area that has already been affected by environmental disturbances like hurricane, earthquake, wildfire etc. The already present SOIL makes it possible for certain organisms to colonize the affected area.
Therefore, succession (specifically secondary succession) is what must occur for a forest ecosystem to recover after a wildlife.
