Answer the following question given this paragraph: Diseases of the endocrine system are fairly common. An endocrine disease usually involves the secretion of too much or not enough hormone by an endocrine gland. This may happen because the gland develops an abnormal lump of cells called a tumor. For example, a tumor of the pituitary gland can cause secretion of too much growth hormone. If this occurs in a child, it may result in very rapid growth and unusual tallness by adulthood. This is called gigantism. Q: An endocrine disease usually involves the secretion of too much or not enough hormone by which gland? Choices: - Pituitary - Thyroid - Pancreas - endocrine A:
endocrine

Answer the following question given this paragraph: Renewable energy resources include solar, water, wind, biomass, and geothermal power. These resources are usually replaced at the same rate that we use them. Scientists know that the Sun will continue to shine for billions of years. So we can use the solar energy without it ever running out. Water flows from high places to lower ones. Wind blows from areas of high pressure to areas of low pressure. We can use the flow of wind and water to generate power. We can count on wind and water to continue to flow! Burning wood ( Figure below ), is an example of biomass energy. Changing grains into biofuels is biomass energy. Biomass is renewable because we can plant new trees or crops to replace the ones we use. Geothermal energy uses water that was heated by hot rocks. There are always more hot rocks available to heat more water. Q: Biomass, solar, wind, water, and geothermal power are examples of what kinds of energy resources? Choices: - mechanical - electrical - fossil fuel - renewable A:
(Answer)
renewable
Ques: Answer the following question given this paragraph: Osmotic pressure is important in biological systems because cell walls are semipermeable membranes. In particular, when a person is receiving intravenous (IV) fluids, the osmotic pressure of the fluid needs to be approximately the same as blood serum; otherwise bad things can happen. Figure 11.4 "Osmotic Pressure and Red Blood Cells" shows three red blood cells: Figure 11.4 "Osmotic Pressure and Red Blood Cells"a shows a healthy red blood cell. Figure 11.4 "Osmotic Pressure and Red Blood Cells"b shows a red blood cell that has been exposed to a lower concentration than normal blood serum (a socalled hypotonic solution); the cell has plumped up as solvent moves into the cell to dilute the solutes inside. Figure 11.4 "Osmotic Pressure and Red Blood Cells"c shows a red blood cell exposed to a higher concentration than normal blood serum (hypertonic); water leaves the red blood cell, so it collapses onto itself. Only when the solutions inside and outside the cell are the same (isotonic) will the red blood cell be able to do its job. Q: Osmotic pressure is important in biological systems because cell walls are what? Choices: - impassable - theonym membranes - variably membranes - semipermeable membranes A:
Ans: semipermeable membranes

Ques:Answer the following question given this paragraph: Herbivores such as zebras and elephants live in herds . Adults in the herd surround and protect the young, who are most vulnerable to predators. Q: Why do adult herbivores in a herd surround their young? Choices: - to protect them from other adult herbivores - to keep them warm on long cold nights - to show them love - to protect them as they are vulnerable to predators A:

Ans:to protect them as they are vulnerable to predators
