Answer:
Entropy of an isolated system either increases or remains constant. If there are no irreversibilities in an isolated system then its entropy will remain constant. But that is a hypothetical case. In real life case, there is always some irreversibility present in the system.
Explanation:
Answer:
e. None of these
Explanation:
The immune deficiency viruses (HIV) are retroviruses that use a reverse transcriptase (RT) enzyme to produce a single-stranded DNA (ssDNA) from an RNA template. The reverse transcription allows retroviruses to replicate their genetic material, which is integrated into the host's genome as a double-stranded linear DNA molecule in a similar way to the mechanism of insertion used by endogenous retrotransposons. The synthesis of DNA is started by cellular tRNAs (tRNA3Lys) that are packaged into the virion. After reverse transcription, the HIV DNA enters the nucleus of CD4 immune cells (also known as CD4+ T cells), and then it integrates into the genome to coopt the host's cell machinery for its own replication.
Fungal species help other organisms in their ecosystems in many ways,
<span>Fungi are decomposes - they recycle the dead organs.
</span>They also maintain overall stability in ecosystem.
The answer is D: test possible choices and then avoid ones that are not desirable.
