Answer the following question given this paragraph: Phagocytosis , or cellular eating, occurs when the dissolved materials enter the cell. The plasma membrane engulfs the solid material, forming a phagocytic vesicle. Q: What is the term for cellular eating? Choices: - Pinocytosis - consumption - ancylosis - phagocytosis A:
phagocytosis
(Question)
Answer the following question given this paragraph: The oxygen enters the bloodstream from the alveoli , tiny sacs in the lungs where gas exchange takes place ( Figure below ). The transfer of oxygen into the blood is through simple diffusion. Q: How is oxygen transferred into the bloodstream? Choices: - mean diffusion - hard diffusion - brain diffusion - simple diffusion A:
(Answer)
simple diffusion
Ques: Answer the following question given this paragraph: Q: Small crustaceans exchange gases across thin areas of the cuticle; larger species have what to accomplish this? Choices: - noses - pores - lungs - gills A:
Ans: gills
(Q).
Answer the following question given this paragraph: In many species display behaviors, rather than actual physical attacks, are used to show aggression. This helps prevent injury and death. Male gorillas, for example, are more likely to put on a display of aggression than to attack another male. In fact, gorillas have a whole series of display behaviors that they use to show aggression. They beat on their chest, dash back and forth, and pound the ground with their hands. Q: How do the male gorillas show display behaviors? Choices: - food gathering - vocalization - spontaneous mutation - showing aggression A:
(A).
showing aggression
Ques:Answer the following question given this paragraph: Regardless of whether reactions are exothermic reactions or endothermic reactions , they all need energy to get started. This energy is called activation energy . Activation energy is like the push you need to start moving down a slide. The push gives you enough energy to start moving. Once you start, you keep moving without being pushed again. Activation energy is defined as the energy that must be overcome in order for a chemical reaction to occur, or the minimum energy required to start a chemical reaction. The concept of activation energy is illustrated in Figure below . Q: What do you call the energy that must be overcome in order for a chemical reaction to occur, or the minimum energy required to start a chemical reaction? Choices: - expression energy - phase energy - kinetic energy - activation energy A:

Ans:activation energy
Ques: Answer the following question given this paragraph: An object will not change its state of motion (i. e. , accelerate) unless an unbalanced force acts on it. Equal and oppositely directed forces on the same object do not produce acceleration. Q: An unbalanced force on an object in motion causes what? Choices: - agitation - velocity - vibration - acceleration A:
Ans:
acceleration
