The latest advance being that of gene sequencing and gene editing tools. </span>
Answer: Because if we assume the cannibal has to fight to the death then the stronger will win and the weaker will die off.
Explanation:
Answer:
Option A, the liquid level in a capillary tube will drop below the surrounding liquid and the surface in the capillary tube will have a convex meniscus.
Explanation:
A liquid will wet the surface of the container in which it is contained only when the adhesive forces between the molecules of the liquid are weaker than the adhesive force between the surface wall of the container and water.
A convex meniscus is formed when the attractive forces between the molecules of liquid (cohesion) becomes greater than attractive forced between the water molecule and the container's surface (adhesion)
Convex meniscus simultaneously move the surface of the liquid in the downward direction due to which its level become lower than the surrounding layer.
Hence, option A is correct
Because people don't pay attention to the road sometimes and they don't realize what is happening in front of then so they try to hit their breaks and there not fast enough so they just crash
