Answer:
The options including the genotypes are not included. On a general note, three genotypes that are possible for this trait including their phenotype is:
WW- Wide wings
Ww- Wide wings
ww- thin wings
Explanation:
This question involves a single gene coding for wings width in a certain bird. The allele for wide wings (W) is dominant over the allele for thin wings (w). This means that allele 'W' will always mask the expression of allele 'w' in a heterozygous state.
There are three possible genotypes considering this trait.
WW- homozygous dominant genotype which wings will be phenotypically wide because it contains a combination of same dominant alleles.
Ww- heterozygous dominant genotype which wings will be phenotypically wide because I this combination of alleles, the W allele will always express itself phenotypically over allele 'w' considering the dominance of W.
ww- homozygous recessive genotype which wings will be phenotype thin because it contains a combination of same recessive alleles.
N.B: a recessive trait will only be expressed in a homozygous condition.
Answer:
The Thalamus relays sensory signals, regulation of consciousness, sleep and alertness. While the pons of the human brain act as message senders and receivers. It also connects the upper and lower part of the brain.

Invasive Species ( just took the test its right)
Answer:
B
Explanation:
Both processes involve cell division as it can either be in meiosis (gamete formation) or mitosis (cell division into identical cells)
The kidneys are the main osmoregulatory organs in mammalian systems; they function to filter blood and maintain the dissolved ion concentrations of body fluids. They are made up internally of three distinct regions—the cortex, medulla, and pelvis.
