Answer: a
Explanation: transcription takes place in the nucleus. RNA leaves the nucleus to go to the ribosome where translation occurs.
Water diffuses from the lumen into the interstitial space during the reabsorption of water in the proximal convoluted tubule due to an increase in the interstitium's osmolarity.
Reabsorption is the process by which water and solutes from the PCT are injected into the blood. From the proximal convoluted tubule, the solutes and water go to the interstitium before entering the peritubular capillaries. The majority of the solutes and 99 percent of the water filtered by the nephron must be reabsorbed; all of these chemicals were "absorbed" in the digestive tract. The peritubular and vasa recta capillaries return reabsorbed fluids and chemicals to the circulation.

The stem has more things to transport that's why it has more vascular bundles. The roots only get water from the ground and moving nutrients from the soil to transfer it to the stem. Having more vascular bundles helps the stems to transfer things to leaves and other parts of the plants.
I believe it's oxygenated or oxygen rich blood away from the heart.
Since all cells in our body contain DNA, there are lots of places for mutations to occur; however, some mutations cannot be passed on to offspring and do not matter for evolution. Somatic mutations<span> occur in non-reproductive cells and won't be passed onto offspring. For example, the golden color on half of this Red Delicious apple was caused by a somatic mutation. Its seeds will not carry the mutation.

A single germ line mutation can have a range of effects:
<span><span>No change occurs in phenotype.
Some mutations don't have any noticeable effect on the phenotype of an organism. This can happen in many situations: perhaps the mutation occurs in a stretch of DNA with no function, or perhaps the mutation occurs in a protein-coding region, but ends up not affecting the amino acid sequence of the protein.</span><span>Small change occurs in phenotype.
A single mutation caused this cat's ears to curl backwards slightly.</span><span>Big change occurs in phenotype.
Some really important phenotypic changes, like DDT resistance in insects are sometimes caused by single mutations. A single mutation can also have strong negative effects for the organism. Mutations that cause the death of an organism are called lethals — and it doesn't get more negative than that.</span></span>
