Answer the following question given this paragraph: Fluid Balance: Edema Edema is the accumulation of excess water in the tissues. It is most common in the soft tissues of the extremities. The physiological causes of edema include water leakage from blood capillaries. Edema is almost always caused by an underlying medical condition, by the use of certain therapeutic drugs, by pregnancy, by localized injury, or by an allergic reaction. In the limbs, the symptoms of edema include swelling of the subcutaneous tissues, an increase in the normal size of the limb, and stretched, tight skin. One quick way to check for subcutaneous edema localized in a limb is to press a finger into the suspected area. Edema is likely if the depression persists for several seconds after the finger is removed (which is called "pitting"). Pulmonary edema is excess fluid in the air sacs of the lungs, a common symptom of heart and/or kidney failure. People with pulmonary edema likely will experience difficulty breathing, and they may experience chest pain. Pulmonary edema can be life threatening, because it compromises gas exchange in the lungs, and anyone having symptoms should immediately seek medical care. In pulmonary edema resulting from heart failure, excessive leakage of water occurs because fluids get "backed up" in the pulmonary capillaries of the lungs, when the left ventricle of the heart is unable to pump sufficient blood into the systemic circulation. Because the left side of the heart is unable to pump out its normal volume of blood, the blood in the pulmonary circulation gets "backed up," starting with the left atrium, then into the pulmonary veins, and then into pulmonary capillaries. The resulting increased hydrostatic pressure within pulmonary capillaries, as blood is still coming in from the pulmonary arteries, causes fluid to be pushed out of them and into lung tissues. Other causes of edema include damage to blood vessels and/or lymphatic vessels, or a decrease in osmotic pressure in chronic and severe liver disease, where the liver is unable to manufacture plasma... Q: What do you call accumulation of excess water in the tissues? Choices: - gout - asthma - diuretic - edema A:
edema

Answer the following question given this paragraph: Plant Responses to Light Plants have a number of sophisticated uses for light that go far beyond their ability to photosynthesize low-molecularweight sugars using only carbon dioxide, light, and water. Photomorphogenesis is the growth and development of plants in response to light. It allows plants to optimize their use of light and space. Photoperiodism is the ability to use light to track time. Plants can tell the time of day and time of year by sensing and using various wavelengths of sunlight. Phototropism is a directional response that allows plants to grow towards, or even away from, light. The sensing of light in the environment is important to plants; it can be crucial for competition and survival. The response of plants to light is mediated by different photoreceptors, which are comprised of a protein covalently bonded to a lightabsorbing pigment called a chromophore. Together, the two are called a chromoprotein. Q: Plants can tell the time of day and time of year by sensing and using various wavelengths of what Choices: - moisture - lunar cycles - precipitation - sunlight A:
(Answer)
sunlight
Ques: Answer the following question given this paragraph: Alpha particles can travel only a few centimeters through air. They can burn the skin but not penetrate it. Beta particles can travel up to a meter through air. They can penetrate and damage skin. Gamma rays can travel thousands of meters through air. They can penetrate and damage cells deep inside the body. Q: What kind of rays can travel thousands of meters through air and can penetrate and damage cells deep inside the body? Choices: - x-rays - cosmic rays - plasma rays - gamma rays A:
Ans: gamma rays

Answer the following question given this paragraph: The kidneys help the body maintain homeostasis in several ways. They filter all the blood in the body many times each day and produce urine. They control the amount of water and dissolved substances in the blood by excreting more or less of them in urine. Q: Which body organ filters the blood in the body and creates urine? Choices: - intestines - liver - the arteries - the kidneys A:
(A).
the kidneys
Ques:Answer the following question given this paragraph: The Golgi apparatus is usually made up of five to eight cup-shaped, membrane-covered stacks of discs called cisternae (singular, cisterna ), as shown in Figure below . Both plant and animal cells have a Golgi apparatus. A typical mammalian cell will have 40 to 80 of these stacks. While plant cells can have up to several hundred Golgi stacks scattered throughout the cytoplasm. In plants, the Golgi apparatus contains enzymes that synthesize some of the cell wall polysaccharides. Q: Which organelle is made up of 5 to eight cup shaped, membrane covered stacks of discs known as cisternae? Choices: - vacuole - nucleus - endoplasmic reticulum - golgi apparatus A:

Ans:golgi apparatus
Answer the following question given this paragraph: Ribosomes are found in both eukaryotic and prokaryotic cells. Ribosomes are not surrounded by a membrane. The other organelles found in eukaryotic cells are surrounded by a membrane. Q: Which type of membrane are ribosomes surrounded by? Choices: - partial - permenant - temporary - none A:
none
