The given statement is True.
The transport process that does not requires the consumption of ATP molecules is called as passive transport. The movement of solute molecules along the concentration gradient (from higher concentration to lower concentration) is called diffusion. This process does not requires ATP for the movement of molecules from one place to another.
Answer:
what are the answers? or is there?
The correct answer would be Fluoride was not used to help protect teeth then
Cavity is not a genetic disease and thus there is no relevance of gene transfer in this case. Thus option A, B and D gets ruled out.
However, flouride in a limited amount is very useful for removing the cavities. Flouride in the foood and water enters the blood stream and make the teeth strong from inside. While the Flouride in Saliva make the teeths stronger and cavity free from outside. It reduces reminization that causes the loss of minerals.
Thus lack of flouride makes the teeth more cavity prone.
That would be D.
The highest temperatures are near the equator and the lowest ones at the poles. So the lower the degree of latitude the higher the temperature.
Answer: HI your question is incomplete but i will provide a general answer that can help you
answer : Permeable Rock layers allow the flow of fluid like substances through them, While Impermeable rock layers do not allow the flow of fluid like substance through them.
Explanation:
Permeable rocks are rocks containing pores through Fluid like substances can penetrate through in the rocks. examples of Permeable rocks are ; Sandstones and Chalk
While an Impermeable rock is a rock that does not allow the flow of fluid like substance through it due to the absence of pores in its rock layers . examples of such rock are ; Clay and marble
Although some permeable rocks might exhibit low level of permeability as well but generally Rock sample with pores are classified as permeable rock layers.
