Answer:
Hepatitis A infection can be prevented by getting vaccine or immune globulin soon after coming into contact with the virus. Persons who have recently been exposed to HAV should get immune globulin or vaccine as soon as possible, but not more than 2 weeks after the last exposure.
Explanation:
You can take steps to reduce the risk of passing hepatitis A to others.
Avoid sexual activity. Avoid all sexual activity if you have hepatitis A.
Wash your hands thoroughly after using the toilet and changing diapers.
Don't prepare food for others while you're actively infected.
Answer:
1, 5, 2, 3, 4
Explanation:
There are several enzymes involved in DNA replication and the step by step process of replication along with enzymes involved is as follows
a) Helicase is the first enzyme to act and it has a very important role in replication. Helicase unwinds the double helix of DNA
b) Single strands binding proteins prevent reattachment of DNA helix
c) Topoisomerase is responsible for relieving or inducing supercoils
d) The primase then lay the starting blocks made from RNA
e) DNA polymerase enzyme III lay the DNA from 5 prime to 3 prime.
f) DNA polymerase enzyme I then do half ladder replication
g) DNA Ligase links all the fragments.
Hence, the correct sequence is 1, 5, 2, 3, 4
Given what we know, we can confirm that Anthony is able to smell the gas in his house because of the activation of his olfactory receptors through the process of sensation.
<h3>What is sensation?</h3>
The sensation is a process that activates for each of the 5 senses. In this process, sensory neurons receive a stimulus and activate, sending a neural impulse to the brain with the information gathered. This information resulted in the ability to identify the smell as gas.
Therefore, we can confirm that Anthony is able to smell the gas in his house because of the activation of his olfactory receptors through the process of sensation.

The four factors that affect evolution are mutations, natural selection, genetic drift and the gene flow, In the case, if the ground finches that Grants studied, we can observe the working of the natural selection. Due to change in the conditions in the environment, the large beak was an advantageous trait that was favored by the natural selection. The result of this process was an increase in numbers of large beaked finches and decrease in small-beaked finches compared to the initial numbers in the population.
