Correct option b) A saturated fatty acid
When only one double bond in the molecules that is also known as monounsaturated fat. If there is more than one double bond that is known as polyunsaturated fat.
Unsaturated fatty acids have one or more than one carbon- carbon band double bonds. That indicates the maximum possible numbers of hydrogen atoms are bonds to each carbon in the molecule. These carbon form double bonds with the carbons next to them.
Alkenes contain carbon- carbon double bonds and unsaturated hydrocarbons with the molecular formula is Cn H2n. This is made of chains where some carbon atoms are not fully saturated with hydrogen atoms.

A week is the correct answer
Because they can usually predict mostly accurately up to 5-7 days which matches the answer for one week.
Hope that helps :)
The exons of the pre -mRNA contain the protein -coding regions.
Pre mRNA is the first made mRNA transcript and requires undergo many post transcriptional modifications for the formation of a mature mRNA.
The exons are the regions of the pre-mRNA that are found in the mature RNA, after the splicing of introns takes place.
RNA splicing is the process in which the non-coding segments of the RNA, which are known as introns, are removed by the help of small nuclear ribonucleoproteins. These SnRNPs make the spliceosome, which catalyzes the process of splicing.
After the introns are removed by the splicing process, the exons are covalently joined, which forms the mature mRNA.

<u>Answer</u>: Dense regular (fibrous) connective tissue.
<u>Explanation</u>:
- <em>Connective tissue</em> is a tissue that performs various functions such as binding, connecting and supporting the other organs or tissues or separating one tissue from another.
- <em>Dense regular connective tissue</em> connects various tissues present in the body.
- Since the fibers are tightly <em>packed</em>, this tissue is <em>dense and fibrous</em>, and because the arrangement of the fibers is in <em>parallel</em> fashion, it is of the <em>regular</em> type.
