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.
The correct answer is: D.carrying messages to other cells
• Allowing polar molecules to enter the cell - Membrane proteins can be involved in transport. This kind of proteins are called channel proteins and usually are integral, transmembrane proteins of the membrane (span across the bilayer). Channel proteins are responsible for facilitated diffusion and active transport of the molecules.
• Recognizing other types of cells- Membrane proteins may function as markers for cellular identification (recognition) and may connect and join two cells together
• Receiving messages – Membrane proteins are often receptors for peptide hormones and thus involved in signal transduction.
Answer: d. an algae that grows on the surfaces of rocks.
Kelps are large brown algae seaweeds that grow along rocky shorelines so we choose d as an answer. Three types of Kelps are found mostly on<span> the Pacific coast, Macrocystis (giant </span>kelp), nereocystis luetkeana) and the Alaria fistulosa.
Kelps which are about 30 different genera, included species from Laminariales and Fucales.
Answer:
D- all. .
Explanation:

Whenever dusting a fingerprint with the fingerprint powder, it must be kept in mind that the color of the powder must contrast the color of the surface. When a fingerprint is discovered on the dark surface, then the fingerprint powder used must be of gray color, so that the print is easily visible when developed. The light color of gray will help the ridges of the print to stand out over the dark surface.
Hence, the correct answer is 'gray.'
