Answer the following question given this paragraph: As the organism grows more sophisticated, gene regulation becomes more complex, though prokaryotic organisms possess some highly regulated systems. Some human genes are controlled by many activators and repressors working together. Obviously, a mutation in a cis-regulatory region, such as the promoter, can greatly affect the proper expression of a gene. It may keep the gene permanently off, such that no protein can be made, or it can keep the gene permanently on, such that the corresponding protein is constantly made. Both of these can have detremental effects on the cell. Q: As the organism grows more sophisticated, what happens to the process of gene regulation? Choices: - degenerates - becomes fractured - becomes simplified - becomes more complex A:
becomes more complex

Answer the following question given this paragraph: Kinetic energy is the energy of moving matter. Anything that is moving has kinetic energyfrom atoms in matter to stars in outer space. Things with kinetic energy can do work. For example, the spinning saw blade in the photo above is doing the work of cutting through a piece of metal. Q: What type of energy is the energy of moving matter? Choices: - dynamic energy - residual energy - potential energy - kinetic energy A:
(Answer)
kinetic energy
Ques: Answer the following question given this paragraph: Gastrulation The typical blastula is a ball of cells. The next stage in embryonic development is the formation of the body plan. The cells in the blastula rearrange themselves spatially to form three layers of cells. This process is called gastrulation. During gastrulation, the blastula folds upon itself to form the three layers of cells. Each of these layers is called a germ layer and each germ layer differentiates into different organ systems. The three germs layers, shown in Figure 43.26, are the endoderm, the ectoderm, and the mesoderm. The ectoderm gives rise to the nervous system and the epidermis. The mesoderm gives rise to the muscle cells and connective tissue in the body. The endoderm gives rise to columnar cells found in the digestive system and many internal organs. Q: What is the process of the blastula forming 3 layers of cells called? Choices: - Mitosis - internalization - fermentation - gastrulation A:
Ans: gastrulation

Ques:Answer the following question given this paragraph: Muscles That Move the Tongue Although the tongue is obviously important for tasting food, it is also necessary for mastication, deglutition (swallowing), and speech (Figure 11.11 and Figure 11.12). Because it is so moveable, the tongue facilitates complex speech patterns and sounds. Q: Besides tasting food, what organ is necessary for mastication, deglutition (swallowing), and speech? Choices: - throat - larnyx - mouth - tongue A:

Ans:tongue
Ques:Answer the following question given this paragraph: The standard cell potential is positive, so the reaction is spontaneous as written. Tin is oxidized at the anode, while silver ion is reduced at the cathode. Note that the voltage for the silver ion reduction is not doubled even though the reduction half-reaction had to be doubled to balance the overall redox equation. Q: Tin is oxidized at the anode, while silver ion is reduced at? Choices: - anodyne - iodine - gamma - cathode A:

Ans:
cathode
