Answer:
A convergent plate boundary is where one of the convergent plates will move beneath the other plate, a process known as subduction. This happens in the lithosphere. A second plate boundary is called a divergent plate boundary. Along these boundaries magma rises from deep within the earth and erupts to form new crust on the lithosphere. The third type of plate boundary occurs where tech tonic plates slide horizontally past each other. This is known as a transform plate boundary.

Answer:
b. The step stool exerts a force on the student in the opposite direction of gravity.
c. A student exerts an upward force on the step stool equal to the gravitational force
Explanation:
It is true that gravity is the force that pulls the objects down to the earth but there are some forces that oppose the statement.
In the given situation, the student is unable to fall down from step stool is because of two forces one, the force exetred by step stool on student and two, the force exerted by the student on step stool.
The step stool exerts a force on the student in the opposite direction of gravity that gives stability to the step stool and an upward force on the step stool equal to the gravitational force helps the student to climb the stool.
Hence, the correct option are b and c.
Answer:
One difference between monotremes and other types of mammals is that monotremes secrete milk through pores on the surface of the mother's abdomen.
Explanation:
Monotremes are three different types of mammals. They are calsified by structural differences in their jaws, reproductive tract, brains, digestive tract, and some other body parts compared to the more common mammalian types. Monotremes secrete milk through pores on the surface of the mother's abdomen, they actually <em>lactate from their mammary glands via openings in their skin.</em>

Explanation:
Image result for what effects do end products have on enzymes
End products can either not have an effect on enzymes, as with many biochemical pathways, but can also inhibit enzymes, especially in anabolic pathways (where larger molecules are synthesised from smaller building blocks) to regulate them
Answer:
Transparent objects allow all the light to pass through them. Opaque ones allow no light to pass through. Translucent allows light to go through but the area in it is no visible to determine the object
Explanation:
Think of Transparent as a window u can see straight through it is clear.Think of Translucent as a window with cold fog on the window light can come through it but you can't see whats outside.Think of Opaque as a black chalkboard light reflect on it but light cannot go through it
