Ques:Answer the following question given this paragraph: Electricity and magnetism are inextricably linked. Under certain conditions, electric current causes a magnetic field. Under other conditions, a magnetic field can cause an electric current. A moving charged particle creates a magnetic field around it. Additionally, when a moving charged particle moves through a different magnetic field, the two magnetic fields will interact. The result is a force exerted on the moving charged particle. Q: Under certain conditions, electric current causes what type of field? Choices: - light - kinetic - seismic - magnetic A:

Ans:magnetic

Ques:Answer the following question given this paragraph: Microfilaments Of the three types of protein fibers in the cytoskeleton, microfilaments are the narrowest. They function in cellular movement, have a diameter of about 7 nm, and are made of two intertwined strands of a globular protein called actin (Figure 4.23). For this reason, microfilaments are also known as actin filaments. Q: What type of protein fibers in the cytoskeleton are the narrowest? Choices: - macrophages - mitosis - capillaries - microfilaments A:

Ans:microfilaments

Ques:Answer the following question given this paragraph: Mammals are a class of endothermic vertebrates. They have four limbs and produce amniotic eggs. Examples of mammals include bats, whales, mice, and humans. Clearly, mammals are a very diverse group. Nonetheless, they share many traits that set them apart from other vertebrates. Q: Mammals belong to which class of vertebrates? Choices: - agnathas - chondrichthyes - placoderms - endothermic A:

Ans:
endothermic
