Answer the following question given this paragraph: Other specialized cells are involved in feeding. Sponges are filter feeders. They filter food out of the water as it flows through them. Sponges pump water into their body through specialized pore cells called porocytes. Q: What type of feeders are sponges? Choices: - bottom feeders - surface feeders - layer feeders - filter feeders A:
filter feeders

Answer the following question given this paragraph: Antidiuretic Hormone (ADH) The solute concentration of the blood, or blood osmolarity, may change in response to the consumption of certain foods and fluids, as well as in response to disease, injury, medications, or other factors. Blood osmolarity is constantly monitored by osmoreceptorsspecialized cells within the hypothalamus that are particularly sensitive to the concentration of sodium ions and other solutes. In response to high blood osmolarity, which can occur during dehydration or following a very salty meal, the osmoreceptors signal the posterior pituitary to release antidiuretic hormone (ADH). The target cells of ADH are located in the tubular cells of the kidneys. Its effect is to increase epithelial permeability to water, allowing increased water reabsorption. The more water reabsorbed from the filtrate, the greater the amount of water that is returned to the blood and the less that is excreted in the urine. A greater concentration of water results in a reduced concentration of solutes. ADH is also known as vasopressin because, in very high concentrations, it causes constriction of blood vessels, which increases blood pressure by increasing peripheral resistance. The release of ADH is controlled by a negative feedback loop. As blood osmolarity decreases, the hypothalamic osmoreceptors sense the change and prompt a corresponding decrease in the secretion of ADH. As a result, less water is reabsorbed from the urine filtrate. Interestingly, drugs can affect the secretion of ADH. For example, alcohol consumption inhibits the release of ADH, resulting in increased urine production that can eventually lead to dehydration and a hangover. A disease called diabetes insipidus is characterized by chronic underproduction of ADH that causes chronic dehydration. Because little ADH is produced and secreted, not enough water is reabsorbed by the kidneys. Although patients feel thirsty, and increase their fluid consumption, this doesn't effectively decrease the solute concentration in their blood because ADH... Q: In response to high blood osmolarity, which can occur during dehydration or following a very salty meal, the osmoreceptors signal the posterior pituitary to release this? Choices: - adrenaline - salt - oxygen - antidiuretic hormone (adh) A:
(Answer)
antidiuretic hormone (adh)
Ques: Answer the following question given this paragraph: Often, new diseases result from the spread of an existing disease from animals to humans. A disease that can be spread from animals to humans is called a zoonosis . When a disease breaks out, scientists called epidemiologists investigate the outbreak, looking for its cause. Epidemiologists are like detectives trying to solve a crime. The information epidemiologists learn is important to understand the pathogen, and help prevent future outbreaks of disease. Q: What is a disease that can be spread from animals to humans called? Choices: - proteolysis - Anthroponosis - parasite - zoonosis A:
Ans: zoonosis

Answer the following question given this paragraph: Mars is the fourth planet from the Sun. It has two small, irregular moons. Mars is red because of rust in its soil. Mars has the largest mountain and the largest canyon in the solar system. Q: What is the fourth planet from the sun? Choices: - Pluto - Saturn - Mercury - mars A:
(A).
mars
Ques:Answer the following question given this paragraph: Radioactive strontium is dangerous because it can chemically replace calcium in the human body. The bones are particularly susceptible to radiation damage. Write the nuclear equation for the beta emission of strontium-90. Q: What can radioactive strontium replace in the human body making it dangerous? Choices: - potassium - oxygen - magnesium - calcium A:

Ans:calcium
Ques:Answer the following question given this paragraph: Sometimes deep ocean water rises to the surface. This is called upwelling . The figure below shows why it happens ( Figure below ). Strong winds blow surface water away from shore. This allows deeper water to flow to the surface and take its place. Q: What phenomenon occurs when strong winds blow surface water away from shore, allowing deeper water to flow to the surface and take its place? Choices: - percolating - hurricane - tsunami - upwelling A:

Ans:
upwelling
