4 is nucleus because it’s in the middle
Whales use their lower jawbone to the middle ear. whereby they can ear clearly while they are in the water. Human ears and dolphins ears they work the same . They receive sound directly from the air.
In similar way dolphins and human ears are placed in basic anatomical location which is same as on the head. Without a medium hearing is not possible.
The medium sound for human is air. Sound travels 343 meters per second in air and 147 meters per second in water. The most effective way of transmitting sound waves is through water.
We can say that the sound will be fast to travel in medium if the molecules are closer.
<span>The answer is B. Human homeostasis alludes to the body's capacity to physiologically control its inward condition to guarantee its soundness in light of variances in the outside condition and the climate. The support of sound circulatory strain is a case of homeostasis.</span>
Answer:
glucose
Explanation:
6CO2(carbon dioxide)+6H2O(water)-->C6H12O6(glucose)+6O2(oxygen)
water is split during the light dependent reactions and the protons are incorporated in a proton carrier that will be used in Calvin's cycle to synthesize glucose
