Answer:
Offspring-heterozygous genotype SsEe
Explanation:
If we name the gene for the body color with S and gene for the eye color with E and if the brown body is dominant over ebony body, while red eyes are dominant over sepia eyes, than the genotypes of the parents would be: female-SSEE, male-ssee
P: SSEE x ssee
Female gametes SE, male gametes se
F1: SsEe all of the offspring would be heterozygous.
Answer:
Option A, Hormones are controlled by a feedback loop; information about a system is sent back to the controller of the system to improve its function.
Explanation:
Negative feedback loop controls the hormone production and release. This is done by eliciting the release of substances till a certain level after which the stop signal is activated thereby preventing further release. By this method, concentration of hormones in blood is maintained within the narrow range.
For example – Thyroid hormones is released when the anterior pituitary signals the thyroid. This continues till the hormones in the blood reach the threshold level. Once the threshold level is reached, hypothalamus receives a feedback and then signals anterior pituitary to inhibit further signaling to the thyroid
Hence, option A is correct
