Answer:
D. Human height is controlled by many genes.
Explanation:
Human height is controlled by many genes. describes a Mendelian trait.
Height is a model trait that is controlled by variant of genes and not by only one gene. Height is a contribution of many genes because the height of a body consists of different body parts, such as the torso, leg bones, and even the neck.
Hence, the correct option is "D".
Answer:
it must be digested into small pieces the body can absorb and use Along the way food is broken down into tiny molecules so that the body can absorb nutrients it needs Starches break down into simple sugars.
Fats break down into into fatty acids and glycerol.
Protein must be
Answer: 60,000 mm2; 1,000,000 mm3; larger
The cell has the same length for all of its side which make it have a cubic shape. The area of 100 mm cube would be: 6 * side * side= 6 * 100 * 100 = 60,000 mm2
The volume of the cube would be: side^3= 100mm^3=1,000,000 mm3
If broken into 10mm cube, it would form 1000 cube. The total area of the cube would be: 1000 * 6* 10 * 10= 600,000 mm2
Answer:
A. Homeostasis allows organisms to regulate their temperature.
Explanation:
Homeostasis is a biological process through which the body of organisms try to maintain a relatively stable body conditions irrespective of the changes in the external environment.
<em>Homeostasis keeps body processes such as temperature, pressure, hydration, pH, etc. relatively stable. While some organisms maintain a stable body temperature by generating heat (endotherms), others do so by adjusting their body temperature to be in tune with that of the external environment (ectotherms). </em>
The correct option is A.
Answer:
Muscle contraction occurs when the thin actin and thick myosin filaments slide past each other. It is generally assumed that this process is driven by cross-bridges which extend from the myosin filaments and cyclically interact with the actin filaments as ATP is hydrolysed.
