Smog is an abiotic factor affecting a biotic factor(s).
This is because smog isn't a living organism so it is abiotic while humans are multicellular organisms so therefore, they are biotic factors.
Smog has a negative effect on many biotic factors.
Answer:
D. it takes millions of years to form
Answer: Option B) each parental strand serves as a template for the synthesis of a complementary strand
Explanation:
In semi-conservative DNA replication,
- a parent double-stranded DNA splits in two.
- Each strand is then read by the enzyme, DNA polymerase, to ensure accurate replication of a newly synthesized strand
- the new strand contains nucleotides that are complimentary to free nucleotides present in the parent strand.
Thus, option B perfectly describes semi-conservative replication of dna
I think the correct answer from the choices listed above is the first option. The sequence that is arranged from the simplest one to the most complex would be:
<span>squamous cell → epithelial tissue → skin → integumentary system → human
</span>
The sequence should start with a single cell, group of cells which makes a tissue, group of tissue, system and the whole body.
