If the parent is a carrier of lung disease then the child may have that chance of getting it.
Answer:
A.
Explanation:
Older fossils tend to lay in the lower levels of the ground. The further up the fossils are, the more likely you are to find something that looks like today. Think of it as stacking papers with different drawings on them from different ages. Oldest goes on the bottom, newest goes on the top. The older layer stands as more of a foundation point while newer layers are around where we are now.
Answer:
Environmental temperature and humidity, altitude, volume of air inspired, air currents, clothing, blood circulation through skin, and water content of the body
Answer:
Cb>Cy>Co>Cr
Explanation:
First of al we need to do the Punnett square. As a result we get the genotypes:
CyCb
CyCr
CoCb
CoCr
Because there are no red frogs, red is the least dominant as it isn't expressed in any genotype.
Half of the progeny are blue and half of the possible genotypes contain the blue allele meaning that blue is expressed in all genotypes. This means that blue is the most dominant.
The only alleles left are yellow and orange. We can deduce that yellow is more dominant than orange because one of the parent frogs is yellow and contains the genes for yellow and orange.
As a result blue is the most dominant, yellow is the second most dominant, orange is the third most dominant and red is the least dominant.
