This energy most directly results from the life activity of respiration.
The hummingbirds have very high energy expenditure (have the highest oxygen requirements of all vertebrae) with a fast heart rate, very fast wing beats and sustained hovering. So the hummingbird is nearly always on the edge of starvation, needing to take in more nectar than its body weight each day.
The respiratory system of these birds is highly adapted for the high oxygen needs. So, the muscles of the hummingbird cause pressure changes within the air sacs. As a result, more oxygen can enter the respiratory system. Also, they have the highest density of red blood cells which allows them to rise heart beat to around 500 breaths per minute during flight.
A natural calamity in which a low pressure centered low atmospheric air movement along with strong winds and rain occurs is called a hurricane it is also known as a tropical cyclone.
The effect that most likely occurs due to a hurricane is:
Option A. Damaged houses due to flooding.
The effect can be explained as:
- The hurricane can cause storm surge in which the levels of the sea rises than normal and causes high tides that can lead to floods.
- The heavy rainfalls and typhoons caused by hurricanes lead to floods that damage homes.
- Hail and forest fires due to lightning strikes are not caused by hurricanes and hence are not affected by the hurricane.
Therefore, hurricane causes flooding.

Answer:
100% black
Explanation:
<em>The allele for black is dominant over that of the grey fur.</em>
Let B represents the allele for black color and b for grey color.
Homozozygous black rabbit will have the genotype: BB
Heterozygous black rabbit will have the genotype: Bb
If the two are crossed;
BB x Bb
Offspring: BB, Bb, BB, and Bb = 2BB and 2Bb
2BB = Black fur
2Bb = Black fur (heterozygous)
Both BB and Bb offspring are black phenotypically.
<em>Hence, all the offspring will appear black, a phenotypical ratio of </em><em>100% black.</em>
