Answer: C
Explanation: Left ventricle. With the thickest muscle mass of all the chambers, the left ventricle is the hardest pumping part of the heart, as it pumps blood that flows to the heart and rest of the body other than the lungs.
Answer:
b) DNA polymerase can synthesize DNA in the 5' to 3' direction
DNA polymerase is only able to synthesize a new strand of DNA and not mRNA. It is only able to do this in the 5' to 3' direction. The leading template strand runs in the 3' to 5' direction and so the new complementary strand is synthesized in a 5' to 3' direction in one continuous run, following the replication fork as it 'unzips' the DNA.
hope it helps btw i did this test and i got it correct
check my screenshot below
please mark me brainliest

C)temperature and rainfall
Explanation:
Temperature and rainfall are the most important physical factors that shapes the characteristics of an ecosystem.
Temperature is the degree of hotness or coldness of a place. It is mostly as a result of the solar radiation it receives.
Rainfall is a form of precipitation in which water falls under gravity in liquid form.
They are both by far the most important factors that shapes ecosystems.

Answer:
They can use the host cell to copy themselves and make viral proteins
Explanation:
Viruses are organisms that are incapable of replicating on their own without infecting a living host. They use the host's ability to transcribe, translate and replicate to replicate themselves and translate their genetic material into proteins. The infection cycle represents their reproductive cycle.
Viruses infect their host cell by initially binding to specific receptors on the host's cell membrane. Then, they enter the host cell and incorporate their genetic material into the host's genome. They, then, use the replicational ability of their host to produce many virions and make proteins.
