Answer: Light can influence gene expression at caterpillar stage which can further influence butterfly wing development. This hypothesis was proved by Thomas Hunt Morgan in 1917 a biologist who conducted studies on butterflies from two different species : <u>Vanessa</u> <u>urtica </u> and <u>Vanessa</u> <u>io </u> caterpillars under red, green, or blue light whereas other caterpillars were kept in the dark. He found that there were differences in color and size of wings of butterflies exposed to different light conditions. Exposure to red light resulted in bright colored wings while exposure to green light resulted in dusky wings. Blue light and dark light resulted in paler colored wings. Also, V. urtica caterpillars reared under blue light and V.io butterflies reared in dark wings developed were larger in size.
Therefore light which is an external environmental factor can influence gene expression which can further influence phenotype of the organism.
Hence in the given situation butterfly would show differences in their wing color if in the caterpillar stage they were grown in dark or bright white light.
Aldosterone hormone would be released in high quantities
when the electrolyte balance in the body is low. This would enable the sodium
ions to be reabsorbed from the glomerular filtrate by the nephrons’ tubules.
ADH (Anti-duretic hormone), on the other hand, would be released in high amounts
if the electrolyte concentration in the body is high. This would enable the
high re-absorption of water from the glomerular filtrate.
Answer:
e
Explanation:
generate energy from the cell
The enzyme that is present within the stomach and the lining of the muscular gland, would function optimally in high H+ concentration and would require much HCl needed for an appropriate pH environment to function
This would be pepsin, I believe.
