The answer is ‘the molecule would have to be longer to be more sensitive to red light and shorter to be more sensitive to blue light.’The cones change shape and vary their length once they absorb a photon. This change is transduced, through biochemical pathways, into nerve impulse and carried to the brain.
Or Genetic drift , bottle neck wasn’t a choice lol
Bottle neck is the answer
Answer: nervous system
Infants need fat as aid in absorption of several vitamins. IT also helps the brain or the nervous system to develop normally. Fats insulate all nervous system tissues in the body. Getting enough of this help infants feel full. It is also essential for growth and development.
Osmolarity of the kidney’s interstitial fluid increases from the cortex to inner medulla. This ensures that there is a concentration gradient that allows for osmosis to take place along the kidney tubules in a kind of countercurrent flow exchange system. This way most, amount of water can be reabsorbed.
The same occurs in the loop of Henle in a process called countercurrent multiplication. The descending loop actively takes up solutes hence making the blood plasma in the the vasa recta highly concentrated. In the ascending loop, therefore, water in the tubules is reabsorbed by osmosis hence making urine more concentrated as it gets to the bladder.
