The distribution of natural resources depends upon number of physical factors like terrain, climate and altitude. The distribution of resources is unequal because these factors differ so much over the earth.

If we draw up a Punnett square, we will see that after crossing two heterozygous individuals the possible offspring are RR, Rr, Rr and rr:
R r
R RR Rr
r Rr rr
Now to produce red flowers, an individual must be either homozygous dominant (RR) or heterozygous (Rr) and so from the Punnett square we can see that 3/4 of the offspring would produce red flowers. If we apply this ratio to 100 offspring, then we get:
3/4*100 = 75 offspring with red flowers, thus the answer is C
The correct option is C.
Primary reinforcer refers to the basic needs of an animal, such as food, water, shelter, etc. Secondary reinforcer, which is also called condition reinforcer refers to the condition in which a stimulus reinforces a behavior after it had been associated with a primary reinforcer.
In the question given above, the primary reiforcer is food.
Answer:
There are two types of endoplasmic reticulum: rough endoplasmic reticulum (rough ER) and smooth endoplasmic reticulum (smooth ER). Both types are present in plant and animal cells. The two types of ER often appear as if separate, but they are sub-compartments of the same organelle.
