Explanation:
Answer:
Epithelial cells also line the inside of your throat, intestines, blood vessels, and all your organs. They are a barrier between the inside and outside of your body and are often the first place that is attacked by viruses as they begin their invasion deeper into the body.
Explanation:
Epithelial tissue covers the outside of the body and lines organs, vessels (blood and lymph), and cavities. Epithelial cells form the thin layer of cells known as the endothelium, which is contiguous with the inner tissue lining of organs such as the brain, lungs, skin, and heart.
C. Positive Feedback
This is because a response to a stimulus( low blood pressure) acts in the same direction as the stimulus ( even lower blood pressure).
This is opposed to negative feedback where the response would go in the operate direction of the stimulus ( I.e. blood pressure increasing in response to low blood pressure)
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.
