Answer:
2. G green (female) x white (male)
Explanation:
<em>The cross that could produce progeny plants with green leaves would be the cross between a green female and a white male.</em>
<u>Since the transmission of leaf color in the plant demonstrates organelle inheritance, the female controls which leaf color is inherited by the progeny. Organelles are generally located in the cytoplasm which is largely contributed by the female egg during fertilization. Hence, organelle inheritance are controlled by the female and that is why they are often referred to as maternal inheritance.</u>
Therefore, a cross involving a green female and a white male would largely yield green progeny provided that the trait inheritance follows an organelle inheritance.
Answer:
When blood glucose level rises beyond the threshold levels, the pancreas secrets hormones insulin. The latter ensures entry of glucose into the cells through Glut transporters for cellular utilization, therefore reducing the blood levels., and promotes storage as glycogen in the liver and muscles.
How ever if the glucose levels drops below the set point, an hormone glucagon is also produce by the pancreas to cause the liver o withdrawal and breakdown glucose storage as glycogen back to glucose thus raising the blood glucose level back to the normal levels.
This is an example of negative feedback mechanism, because the increase in the input levels (blood glucose levels) brings about a counter mechanisms (insulin secretions)as output , to reduce the elevated levels by promoting entry into the cells,, thus bringing the levels to threshold levels.
Thus insulin is acting in a negative feedback mechanism to control blood glucose levels
Explanation:
They both need food, when they die they don't
The answer is letter A. According to the principal of dominance, if a recessive gene for tallness is paired with another recessive gene for tallness, the organism will be tall.<span>
By principle, any of two recessive genes will form the characteristic it holds. Dominant genes however only require one to for a trait.
