Answer:
1/2
Explanation:
This question involves a single gene coding for feather color in chickens. The black allele (B) is incompletely dominant over the white allele (W). This means that the allele B will not mask the phenotypic expression of allele W, hence, a third intermediate blue phenotype (BW) will be produced.
According to the question, if two blue chickens are crossed i.e. BW × BW, the gametes B and W will be produced by each parent. Using these gametes in a punnet square (see attached image), the following offsprings will be produced:
BB, BW and WW in the ratio 1:2:1
BB is black, BW is blue, WW is white. Hence, the probability of producing a blue chicken from this cross is 1/2.

One major reason for exploring extreme environments is to find new resources. An example of a resource is the search for a new antibiotic. Extreme environments have rare species endemic to the regions which can offer different insights from the normative environment we are used to.
No, I would not. This is because the risk of death is higher in an extreme environment. Example of these risks are deadly diseases or harsh climate. The body may be unable to adjust to the extreme environment hence may be unable to restore homoeostasis; such as in restoring body heat in extremely cold environments hence leading to hypothermia.
Answer:
B. lined up perpendicular to the long axis of the bone, in the direction of perforating canals.
Explanation:
Osteons are formations of concentric bone layers (lamellae) that tend to <em>run parallel to the long axis of a bone.</em> They sorround the Haversian canal, a canal that contains blood vessels that supply the osteocytes and are the structural unit of compact bone.
