Answer:
we mean global warming
Explanation:
climate change like heat up, EXAMPLE, your microwave
Answer:
The correct answer is stem cell
Explanation:
Stem cells are the cells that can convert into any specific type of cell by dividing it repeatedly. So stem cells are unspecialized and can give rise to specialized cells.
As they can divide repeatedly and give rise to a specialized type of cell they allow the body to heal, repair and grow. There are different types of stem cell like induced pluripotent cell, adult stem cell, an embryonic stem cell.
Stem cell transplant is used to in the patient who cannot produce normal blood cell, for example, bone marrow transplant.
For number 1, you need the chart so I can't answer it. Sorry.
For number 2, your answer will be B because when he said "survival of the fittest", he meant that organisms with the correct adaptations for survival would live and reproduce, passing those adaptations down the line.
For number 3, your answer will be D because, like I said above, animals that have advantageous traits will survive and reproduce and pass along those traits. Which, essentially, is the process of evolution.
I hope I was able to help you. Best of luck!
Answer:
Two European men and two Polynesian women settled on a previously uninhabited tropical island. All four of the settlers have brown eyes, a dominant trait, but one of the Europeans is heterozygous and carries the recessive gene for blue eyes. No new settlers arrive,and nobody leaves the island.After a few generations,the percentage of blue-eyed individuals increases from the original zero to 25 percent.This is probably due to which of the following factors?
genetic drift
Explanation:
Genetic drift entails when there are changes in the gene frequency which occur in a gene that is existing. From the analogy above, it is a known fact that only gneetic drift could allow such to happen as mutation will only occur with a sudden change of gene which is not the case described above
I think its d) gps technology has led development of robotic tractors for planting,fertilization, and crop harvesting
