Correct answer: B). The fittest organisms are selected for.
The theory of Natural selection is given by Charles Darwin, according to it, the natural selection is the process in which the organism that is more suited are selected by the natural selection and they are most likely to survive and reproduce in order to pass these traits to the next generation.
The organism with the highest survival and reproduction will be those whose genes best represented in the next generation. Natural selection occurs to cause evolution and select the fittest.

A.a classroom compound microscope
B.a transmission electron microscope
C.a scanning electron microscope
D.a scanning tunneling microscope.
Scanning electron microscope is a form of electron microscope that has the capacity to produced the image of a viewed substance by scanning the surface of the sample with a strong beam of focused electrons. The microscope is typically used to obtain information about the surface structure and composition of solid substances.
Answer: 170 calories.
Explanation:
The Viceroy caterpillars feeds on the green plants and trees for its survival. The total energy that is incorporated in the body of the caterpillar is used in cellular respiration, faces and rest amount of the energy left is used as biomass by the caterpillar each day.
The total energy is 1000 calories, 50% of this energy is 500 calories which is released out of the body through faces. Rest 33% of total energy( 330 calories) is used in cellular respiration.
The rest amount of energy that is available is 170 calories.
<span>this statement is actually true. Charles Darwin created his theory of evolution by natural selection in 1859. It was an explanation for how species adapt and carry on. He believed that natural selection was something that occurred that allowed each slight variation of a trait in things to be useful and be preserved.</span>
Answer: Stomata plays very crucial roles in plants. During photosynthesis, gas exchange takes place via the stomata. Water also evaporates from plants through the stomata. In plants, most of the stomata are usually on the bottom of the leaf IN ORDER TO PREVENT EXCESSIVE LOSS OF WATER.
During the day, the sunlight falls on the leaf directly and draws water from the plants. Locating the stomata at the underside of the leave reduces the amount of water that can be lost through excessive evaporation. Also, locating the stomata on the underside of leaves prevent the leaves from taking in too much water during rainfall.
