Answer the following question given this paragraph: Transgenic Animals Although several recombinant proteins used in medicine are successfully produced in bacteria, some proteins require a eukaryotic animal host for proper processing. For this reason, the desired genes are cloned and expressed in animals, such as sheep, goats, chickens, and mice. Animals that have been modified to express recombinant DNA are called transgenic animals. Several human proteins are expressed in the milk of transgenic sheep and goats, and some are expressed in the eggs of chickens. Mice have been used extensively for expressing and studying the effects of recombinant genes and mutations. Q: Animals that have been modified to express recombinant dna are called what? Choices: - reproducing animals - mammalian animals - aquatic animals - transgenic animals A:
transgenic animals

Answer the following question given this paragraph: Photography by Kat. Ferns are common in the understory of the tropical rainforest . CC BY 2.0. Q: In a tropical rainforest, where are ferns common? Choices: - forrest floor - emergent - canopy - understory A:
(Answer)
understory
Ques: Answer the following question given this paragraph: The period to which a given element belongs can easily be determined from its electron configuration. For example, consider the element nickel (Ni). Its electron configuration is [Ar]3 d 8 4 s 2 . The highest occupied principal energy level is the fourth, indicated by the 4 in the 4 s 2 portion of the configuration. Therefore, nickel can be found in the fourth period of the periodic table. Q: In which period of the periodic table is nickel found? Choices: - First Period - Second Period - Third Period - fourth period A:
Ans: fourth period

Answer the following question given this paragraph: 12.7 Molecular Transport Phenomena: Diffusion, Osmosis, and Related Processes Diffusion There is something fishy about the ice cube from your freezerhow did it pick up those food odors? How does soaking a sprained ankle in Epsom salt reduce swelling? The answer to these questions are related to atomic and molecular transport phenomenaanother mode of fluid motion. Atoms and molecules are in constant motion at any temperature. In fluids they move about randomly even in the absence of macroscopic flow. This motion is called a random walk and is illustrated in Figure 12.20. Diffusion is the movement of substances due to random thermal molecular motion. Fluids, like fish fumes or odors entering ice cubes, can even diffuse through solids. Diffusion is a slow process over macroscopic distances. The densities of common materials are great enough that molecules cannot travel very far before having a collision that can scatter them in any direction, including straight backward. It can be shown that the average distance x rms that a molecule travels is proportional to the square root of time:. Q: What is the term for the movement of substances due to random thermal molecular motion? Choices: - Transfusion - convection - condensation - diffusion A:
(A).
diffusion
Ques:Answer the following question given this paragraph: Sometimes air doesn't mix in the troposphere. This happens when air is cooler close to the ground than it is above. The cool air is dense, so it stays near the ground. This is called a temperature inversion ( Figure below ). An inversion can trap air pollution near the surface. Temperature inversions are more common in the winter. Can you explain why?. Q: In what season are temperature inversions more common? Choices: - spring - autumn - summer - winter A:

Ans:winter
Answer the following question given this paragraph: Lizards and snakes belong to the largest order of reptiles, Squamata. Lizards are a large group of reptiles, with nearly 5,000 species, living on every continent except Antarctica. Some places are just too cold for lizards. Q: Squamata is the largest order of what broad animal group, and includes lizards and snakes? Choices: - amphibians - spiny fishes - mammals - reptiles A:
reptiles
