Answer:
Alleles for feather colour exhibit incomplete dominance or co-dominance.
50% gray offspring + 50% black offspring
Explanation:
<em>It means that the alleles for feather colour in the hen exhibit incomplete dominance or co-dominance over one another.</em>
Assuming the allele for white colour is B, white colour will be b while the heterozygote Bb gives the gray phenotype.
Gray rooster + gray hen = 15 gray chicks, 6 black chicks and 8 white chicks.
15:6:8 is roughly 2:1:1 which is phenotypic ratio obtainable from crossing two heterozygous individuals as pointed out by Mendel.
Bb x Bb = 1BB, 2Bb, and 1bb
Crossing the gray rooster (Bb) with a black hen (bb):
Bb x bb = Bb, Bb, bb, and bb
= 2Bb (gray):2bb (black)
50% of the offspring will be gray while the remaining 50% will be black.

Answer:
b.)water + carbon dioxide → sugar + oxygen
Explanation:
Photosynthesis is the process by which plants and other organisms convert carbon dioxide into sugars and other organic compounds by the use of solar energy
In this process raw materials which is water and carbon dioxide are converted to sugars and oxygen which are the end products through the use of sunlight
Take for example - you touching something sharp and instantly moving your hand away.
Sensory neurons in your fingers detect the external stimuli of the sharp object and send a nerve impulse to the spinal cord (does not reach brain) and is sent back to a motor neurone - attached to an effector that moves the muscle and moves the hand away. This is a rapid reflex action and involuntary.
Answer:
Kidney disorder is responsible for the disturbance occur in the balance of the body because kidney release certain harmones which are necessary for normal growth.
Explanation: There are three harmones releases by kidney i. e. erythropoietin, calcitriol, and renin. Erythropoietin is released by kidney when oxygen level is low in the tissue. It also controls the production of red blood cells. Calcitriol harmone controls the concentration of phosphorous and calcium in the blood. Renin is responsible for the increase in blood pressure when it is needed. So if the disorder of kidney occurs, imbalance occurs in the body.
