Answer:
Mitochondria
Explanation:
Mitochondria is the site of cellular respiration which produces energy. A cell with few energy needs would therefore contain a small number of this organelle.
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.
It is d I’m sure though it is b pretty sure explanation
