Answer:
Viruses are smaller and simpler in construction than unicellular microorganisms, and they contain only one type of nucleic acid—either DNA or RNA—never both.
Explanation:
Answer:
It will shrink because it was placed in a hyper tonic solution
Explanation: Hyper tonic = More solute (sugar)
Hypo tonic = more liquid (water)
When a cell is placed in a solution it will essentially try to balance out so in this case water goes out the cell and solute goes, in shrinking the cell.
Answer:
When you sit on a plane for 6 hours without moving, blood accumulates in your veins, and the moment you get up, gravitational forces affect venous return, cardiac output, blood pressure, and venous pressure. That way, when you're sitting on a plane, the gravitational force is the same at the upper and lower extremities, such as the chest, abdomen, and legs, causing venous blood pressure and volume to be evenly distributed throughout the body. However, when one gets up, one becomes dizzy because of abnormal regulation of blood pressure. This is because gravity causes blood to accumulate in the lower extremities (veins of the legs and trunk). This lowers the blood pressure and the blood that the heart pumps. By causing blood to accumulate in the lower extremities, and as venous compliance increases, the veins expand with blood that causes the volume of blood to shift in the veins. This increases the volume and venous pressure in the lower extremities when standing. And the volume of thoracic venous blood is less and less central venous pressure. This leads to a decline in stroke volume. Cardiac output and mean arterial pressure also decrease as left ventricular stroke volume decreases, reducing pulmonary venous return. Decreased standing blood pressure, referred to as orthostatic or postural hypotension. Thus, lowering blood pressure decreases cerebral blood flow, which means less range of blood in the brain causing dizziness.
Explanation:
The answer is D because if organisms live in a desert biome then these organisms should be used to the hot temperatures, water loss, and strong winds.
Answer:
The active transport and the facilitated diffusion both involve the proteins present in the cell membrane. Facilitated diffusion transport the large and the charged molecules through the protein transport channels present in the cell membrane
