Answer the following question given this paragraph: The cerebrum is the largest part of the brain. It controls conscious functions such as reasoning, language, sight, touch, and hearing. It is divided into two hemispheres, or halves. The hemispheres are very similar but not identical to one another. They are connected by a thick bundle of axons deep within the brain. Each hemisphere is further divided into the four lobes shown in Figure below . Q: What is the largest part of the brain? Choices: - cerebellum - limbic system - stem - cerebrum A:
cerebrum

Answer the following question given this paragraph: An example of a human polygenic trait is adult height. Several genes, each with more than one allele, contribute to this trait, so there are many possible adult heights. For example, one adult's height might be 1.655 m (5.430 feet), and another adult's height might be 1.656 m (5.433 feet) tall. Adult height ranges from less than 5 feet to more than 6 feet, but the majority of people fall near the middle of the range, as shown in Figure below . Q: Because several genes, each with more than one allele, contribute to determining height in humans, height is considered what kind of trait? Choices: - adaptive - maladaptive - epigenetic - polygenic A:
(Answer)
polygenic
Ques: Answer the following question given this paragraph: 47.2 The Importance of Biodiversity to Human Life Humans use many compounds that were first discovered or derived from living organisms as medicines: secondary plant compounds, animal toxins, and antibiotics produced by bacteria and fungi. More medicines are expected to be discovered in nature. Loss of biodiversity will impact the number of pharmaceuticals available to humans. Crop diversity is a requirement for food security, and it is being lost. The loss of wild relatives to crops also threatens breeders' abilities to create new varieties. Ecosystems provide ecosystem services that support human agriculture: pollination, nutrient cycling, pest control, and soil development and maintenance. Loss of biodiversity threatens these ecosystem services and risks making food production more expensive or impossible. Wild food sources are mainly aquatic, but few are being managed for sustainability. Fisheries' ability to provide protein to human populations is threatened when extinction occurs. Biodiversity may provide important psychological benefits to humans. Additionally, there are moral arguments for the maintenance of biodiversity. Q: Humans use many compounds that were first discovered or derived from living organisms as medicines: secondary plant compounds, animal toxins, and antibiotics produced by these? Choices: - bacteria and tumors - molecules and fungi - tumors and fungi - bacteria and fungi A:
Ans: bacteria and fungi

Answer the following question given this paragraph: A suspension is a heterogeneous mixture in which some of the particles settle out of the mixture upon standing. The particles in a suspension are far larger than those of a solution and thus gravity is able to pull them down out of the dispersion medium (water). The typical diameter for the dispersed particles (the sand) of a suspension is about 1000 times greater than those of a solution (less than approximately two nanometers for particles in solution, compared to greater than 1000 nanometers for particles in suspension). Unlike in a solution, the dispersed particles can be separated from the dispersion medium by filtering. Suspensions are heterogeneous because at least two different substances in the mixture can be identified. Q: What do you call a mixture in which some particles settle out of it when it is left standing? Choices: - emulsion - alloy - homogenous - suspension A:
(A).
suspension
Ques:Answer the following question given this paragraph: Q: The arid environment of a desert, for instance, can quickly deplete an animal of what? Choices: - strength - protein - air - water A:

Ans:water
Ques:Answer the following question given this paragraph: Total internal reflection allows the light to travel down the optical fiber and not pass through the sides of the tube. The light continuously reflects from the inside of the tube and eventually comes out the end. Optical fibers make interesting lamps but they are also used to transport telephone and television signals. Q: What kind of fibers are used to transport telephone and television signals? Choices: - touch fibers - process fibers - hair fibers - optical fibers A:

Ans:
optical fibers
