Answer:

Option-B

Explanation:

DNA replication is a process which replicates the DNA in a cell and increases the amount of DNA mediated by the enzymes.

The DNA replication begins when the Helicase enzyme opens the DNA and primase form an RNA molecule with a complementary sequence at 5' end of DNA which acts as a primer. The DNA polymerase can add the nucleotide after it binds the RNA primer as primer provides it's 3'-OH group to bind new nucleotides.

Since RNA molecule acts as a primer in the replication process to which the new nucleotides will be added, therefore, the Option-B is the correct answer.

Evidence that visual input is routed from the thalamus directly to an emotional control center in the brain has been used to sup
Marina86 [1]
This evidence supports the claim that some emotional reactions may occur without conscious thinking.
Thalamus is a small brain area located above the brain stem, with the main function of sending motor and sensory signals from the spinal cord and the mid-brain structures to the cerebral cortex.

Amygdala is a small brain region, which is part of the limbic system. It is considered the emotional control centre of the brain since it regulates emotions, survival instincts and some memory functions.

It has been proven that visual input is directly sent by the thalamus to the amygdala, which can trigger some emotional responses (such as fear) without any conscious processing.

How do animals and humans cause erosion ?​
erastova [34]

Animals cause erosion in other ways too. When too many animals live in one place, they tend to eat and trample all the plants. Without the plants to protect the soil, it is much more likely to be eroded by wind and water. Animals cause weathering and erosion on rocky shorelines.
