Answer:
They form new minerals.
Explanation:
Heat causes minerals to change their physical structure. They will form new minerals that are more stable in the new environment.
Answer:
The predation pressure increases mate
Explanation:
Since the observation of the scientist goes in order to increase the coloration in males, because of the predation pressure, and as a consequence the females are attracted by this colored mates.
It will be expected that the increase in pressure, it will increase the colored in skin, and this could end in an increase of the number of mates per male.
Answer: d. in the body can operate at a mechanical advantage or mechanical disadvantage, depending on specific location.
Explanation:
A first-class lever is defined as the force in which fulcrum is present in the center and the load and effort on each side of the fulcrum. First class lever moves over a large distance to move the load to a smaller distance.
First-class lever can be operated at mechanical advantage or disadvantage that it can aid in work by changing the direction of the force and by increasing the efficiency. As the the fulcrum is between the load and the effort so the length of the effort arm divided by the length of the effort arm.
If the fulcrum is closer to the effort, it will operated at mechanical disadvantage and vice versa.
Example of first class levers includes scissors, a claw hammer, a see-saw and a weighing balance.
Hence, the correct option is D.
Here is the answer. In the sliding-filament model, if myosin did not attach to actin filaments, what happens is that, the muscle would be permanently relaxed. Myosins work with actins and these are motor proteins. Hope this is the answer that you are looking for.
Answer:
Most living tissue contains catalase. We can use potatoes to help see catalase work because bubbles of oxygen form when we put potatoes into hydrogen peroxide.
Explanation:
As catalase decomposes hydrogen peroxide into water and oxygen gas, bubbles of oxygen collect on the disk. When the density of the combined paper/enzyme/O2 is less than the solution the disc will rise to the surface.
