Answer:
survival of young giraffes is related to spot pattern, which might help provide camouflage from predators. ... This study revealed that newborn giraffes with larger spots and irregularly-shaped spots had increased survival during the first few months of life.
Explanation:
Large predators are found at higher trophic levels because specialized bodies are needed to extract the small energy that gets to them.
The energy that gets to successive trophic levels decreases progressively because much of it is lost as heat. This means that a small percentage of the energy from the producers that form the bases of trophic levels to the predators that are somewhat at the top of trophic levels.
With big body size, the bodies of predators are organized into systems that work together to efficiently extract the small energy that gets to them from immediate lower trophic level.

Ethanol has been shown to slow down the body's use of fat for fuel by as much as a third, causing more fat to be stored. (or 33%)

Answer:
False
Explanation:
The papillary muscles of both right and left ventricles began to contract shortly before the other ventricular muscles (systole) so that they can take up the slack on the chordae tendineae as the full force of ventricular contractions sends blood against the atrioventricular (AV) valve flaps.
They prevent the backward flow of blood to atria from ventricles. So if they contract after the ventricle systole they would not be able to perform their job.
