Answer the following question given this paragraph: Non-steroid hormones are made of amino acids. They are not fat soluble, so they cannot diffuse across the plasma membrane of target cells. Instead, a non-steroid hormone binds to a receptor on the cell membrane (see Figure below ). The binding of the hormone triggers an enzyme inside the cell membrane. The enzyme activates another molecule, called the second messenger, which influences processes inside the cell. Most endocrine hormones are non-steroid hormones, including insulin and thyroid hormones. Q: What are non-steroid hormones made of? Choices: - proteins - Molecules - fats - amino acids A:
(Answer)
amino acids

Ques:Answer the following question given this paragraph: An electromagnetic wave begins when an electrically charged particle vibrates. This causes a vibrating electric field, which in turn creates a vibrating magnetic field. The two vibrating fields together form an electromagnetic wave. Q: An electromagnetic wave begins with what movement by an electrically charged particle? Choices: - acceleration - diffusion - momentum - vibration A:

Ans:vibration
Ques: Answer the following question given this paragraph: Although renewable, soil takes a very long time to formup to hundreds of millions of years. So, for human purposes, soil is a nonrenewable resource. It is also constantly depleted of nutrients through careless use, and eroded by wind and water. For example, misuse of soil caused a huge amount of it to simply blow away in the 1930s during the Dust Bowl (see Figure below ). Soil must be used wisely to preserve it for the future. Conservation practices include contour plowing and terracing. Both reduce soil erosion. Soil also must be protected from toxic wastes. Q: What kind of a resource is soil, for human purposes? Choices: - renewable resource - guarana resource - emanates resource - nonrenewable resource A:
Ans:
nonrenewable resource
