The middle turqois-ish color is Nucleus
The one on the bottom right is cell membrane
The one on the bottom left is cell wall
<span>(4) active transport
</span>Active transport is the movement of molecules across a cell membrane in the direction against their concentration gradient, i.e. moving from an area of lower concentration to an area of higher concentration.
<span>The answer is a), all red, as no white alleles are present in the parents, [ and hence cannot be passed on to the offspring. Showing work- Let R represent the dominant (red) allele: RR(male) x RR(female) ----> All RR offspring.</span>
<span>Which of the following is true of all greenhouse gases?
</span>
C. THEY TRAP ENERGY IN THE ATMOSPHERE.
They are not naturally occurring. They are the result of human activity like using electricity, burning fuel, etc.
They don't exist in fixed quantities and they don't reflect incoming radiation. The volume of greenhouse gases emitted depends on the activity done. It also does not stay in one place, it moves around and combines with other green house gases; trapping heat in the atmosphere and making the Earth warmer.
