I believe the answer is: D) supplying oxygenated blood to the arteries that travel to all major parts.
The function of the aorta is to supply oxygen-rich blood to the rest of the body into systemic circulation. This differs from answer choice A because choice A seems to be discussing pulmonary circulation, as opposed to systemic. (Pulmonary circulation occurs within the heart and lungs; systemic circulation occurs throughout the body.) Therefore, if the aorta of a human heart is damaged, the ability to supply oxygenated blood to major body parts would be affected.
Answer:
Protists are eukaryotic organisms that cannot be classified as a plant, animal, or fungus. They are mostly unicellular, but some, like algae, are multicellular. ... Protists can be heterotrophic, which means they obtain the energy they need to live by consuming other organisms.

Genetic information is found in DNA, which is found in the nucleus. it could also be chromosomes, however.
Answer:
Plants must have evolved in a manner where they require less water and nutrients as these two were the only limiting factor and carbon dioxide was in abundance
Explanation:
Some 400,000 years ago, the concentration of CO2 was very high and was near to 1000 ppm. At this high concentration of CO2 the photosynthetic activity of plants becomes very high and thus since 400,000 years ago plants could have evolved in an uncontrolled manner but this does not happened. So the reason behind this is limitation in terms of soil and its constituent’s nutrients availability and also limited supply of water.
Therefore, if plants would have evolved themselves in a manner where they require less water and nutrients then they would have grown limitless.
A plant that has flower parts that occur in multiples of four or five is usually a dicot
