Answer:
J. W. Tutt suggested that peppered moths were an example of natural selection.
Explanation: Before industrial revolution, the population of white peppered moth is high as compared to dark peppered moth because white peppered moth can't be seen at night by the birds. After industrial revolution, sooth is spread on the surface of the trees which make easy for the bird to see white peppered moth and feeds on them. Population of white peppered moth decreases while the population of dark peppered moth increased because they cannot be seen in the dark due to black color of sooth.
<u>ANSWER:</u>
The correct order is- Zygote, Blastula, Gastrula, Fetus.
<u>EXPLANATION:</u>
- The embryo develops from the zygote which is formed when the gametes fuse in the process of "fertilization".
- The zygote undergoes cell division to form blastula which is a "ball of cells".
- Gastrula leads to the rearrangement of cells of the blastula into three layers that differentiate into different systems of organ.
- The last stage is the fetus which then develops into a baby.
