Answer the following question given this paragraph: 11.4 Variation of Pressure with Depth in a Fluid If your ears have ever popped on a plane flight or ached during a deep dive in a swimming pool, you have experienced the effect of depth on pressure in a fluid. At the Earth's surface, the air pressure exerted on you is a result of the weight of air above you. This pressure is reduced as you climb up in altitude and the weight of air above you decreases. Under water, the pressure exerted on you increases with increasing depth. In this case, the pressure being exerted upon you is a result of both the weight of water above you and that of the atmosphere above you. You may notice an air pressure change on an elevator ride that transports you many stories, but you need only dive a meter or so below the surface of a pool to feel a pressure increase. The difference is that water is much denser than air, about 775 times as dense. Consider the container in Figure 11.10. Its bottom supports the weight of the fluid in it. Let us calculate the pressure exerted on the bottom by the weight of the fluid. That pressure is the weight of the fluid mg divided by the area A supporting it (the area of the bottom of the container):. Q: At the earth's surface, the air pressure exerted on you is a result of the weight of what above you? Choices: - magnetic force - humidity - water - air A:
air

Answer the following question given this paragraph: A Mendelian trait is a trait that is controlled by a single gene that has two alleles. One of these alleles is dominant and the other is recessive. Many inheritable conditions in humans are passed to offspring in a simple Mendelian fashion. Medical professionals use Mendel's laws to predict and understand the inheritance of certain traits in their patients. Also, farmers, animal breeders, and horticulturists who breed organisms can predict outcomes of crosses by understanding Mendelian inheritance and probability. Q: A trait controlled by a single gene that has two alleles is given what name, after the scientist who studied inheritance? Choices: - darwinian trait - rosilin trait - carlinian trait - mendelian trait A:
(Answer)
mendelian trait
Ques: Answer the following question given this paragraph: A species is a group of individuals that are genetically related and can breed to produce fertile young. Individuals are not members of the same species if their members cannot produce offspring that can also have children. The second word in the two word name given to every organism is the species name. For example, in Homo sapiens , sapiens is the species name. Q: A group of individuals that consists of genetically related individuals that can breed to produce fertile young is known as what? Choices: - colonies - community - population - species A:
Ans: species
(Q).
Answer the following question given this paragraph: Hormonal Regulation of the Reproductive System Regulation of the reproductive system is a process that requires the action of hormones from the pituitary gland, the adrenal cortex, and the gonads. During puberty in both males and females, the hypothalamus produces gonadotropin-releasing hormone (GnRH), which stimulates the production and release of follicle-stimulating hormone (FSH) and luteinizing hormone (LH) from the anterior pituitary gland. These hormones regulate the gonads (testes in males and ovaries in females) and therefore are called gonadotropins. In both males and females, FSH stimulates gamete production and LH stimulates production of hormones by the gonads. An increase in gonad hormone levels inhibits GnRH production through a negative feedback loop. Regulation of the Male Reproductive System In males, FSH stimulates the maturation of sperm cells. FSH production is inhibited by the hormone inhibin, which is released by the testes. LH stimulates production of the sex hormones ( androgens) by the interstitial cells of the testes and therefore is also called interstitial cell-stimulating hormone. The most widely known androgen in males is testosterone. Testosterone promotes the production of sperm and masculine characteristics. The adrenal cortex also produces small amounts of testosterone precursor, although the role of this additional hormone production is not fully understood. Q: Regulation of the reproductive system is a process that requires the action of hormones from which gland? Choices: - salivary gland - adrenal gland - thyroid gland - pituitary gland A:
(A).
pituitary gland
Ques:Answer the following question given this paragraph: Mechanical energy commonly changes between kinetic and potential energy. Kinetic energy is the energy of moving objects. Potential energy is energy that is stored in objects, typically because of their position or shape. Kinetic energy can be used to change the position or shape of an object, giving it potential energy. Potential energy gives the object the potential to move. If it does, the potential energy changes back to kinetic energy. Q: What type of energy can be used to change the position or shape of an object, thus giving it potential energy? Choices: - static energy - binary energy - harmonic energy - kinetic energy A:

Ans:kinetic energy
Question: Answer the following question given this paragraph: Matter has both physical and chemical properties. Physical properties can be measured or observed without matter changing to a different substance. Q: What are the two types of properties that matter has? Choices: - nature and purpose - composition and weight - size and shape - physical and chemical A:
Answer:
physical and chemical
