Answer:
Option (D).
Explanation:
Telomerase enzyme is necessary for the replication of telomeres. This enzymes are also known as terminal transferase and made of ribonucleoprotein.
The increased telomerase activity is the common characteristics of the cancer cell that distinguish them from the normal cells. The cancer cells divide continuously and require the telomerase activity for the end replication of the DNA.
Thus, the correct answer is option (D).
Answer:
Neuroscientists conducted research with taxicab drivers in London and found that taxicab drivers, who are required to have a tremendous amount of spatial and geographic knowledge, had a larger <u>hippocampus</u> than other drivers.
Option D.hippocampus
Explanation:
Hippocampus is concerned with following important functions:
- Storage of new information in the memory (converting short memories into long memories)
- Comparing sensory information with what the brain expects about the world
- Enabling us to form spatial memories for investigating the environment
As the geographic knowledge and spatial knowledge is being stored in the hippocampus, the taxi driver surely have greater hippocampus than other drivers.
<span>It is called fertilization, an egg is penetrated by a sperm cell, and the haploid genetic information of both male and female gametes combines. The result of this process is a diploid cell called a Zygote. A zygote cell receives half chromosomes from its female parent and half from it's male parent. </span>
Too much fertilizer can ruin the earth because it releases methane gas which it harmful for the envoronment
Answer:
scientific consensus changed as scientists learned more about organisms.
Explanation:
Advancements in DNA technology has now given scientists more powerful and insightful tools to further investigate the relationships amongst organisms.
i hope this helps good luck!
