Answer:
Blood vessels are the channels or conduits through which blood is distributed to body tissues. The vessels make up two closed systems of tubes that begin and end at the heart. One system, the pulmonary vessels, transports blood from the right ventricle to the lungs and back to the left atrium.
Explanation:
If a biologist is measuring diversity by calculating the proportion of individuals of each species, he or she is actually calculating the species evenness of species in the community.
<h3>What is species evenness?</h3>
- When there is an environmental gradient in the study region, systematic sampling is performed.
- To take systematic samples along the environmental gradient, a transect is utilized.
- A population is a collection of creatures belonging to the same species that coexist in a certain location.
- Within a given area, more than one population may exist.
- It's possible for populations of Saguaro cacti, Cactus Wrens, and Bark Scorpions to coexist in the same places.
- A population is a collection of people belonging to the same species who are present in the same location at the same time.
- All of the people in all of the interacting populations in a given area make up a community.

Answer: 23
Explanation:
Normal cells have 46, and sex cells have half of a normal cell. The sperm would contain the other half.

Antisense RNAs are utilized for gene regulation and specifically target mRNA molecules that are used for protein synthesis.
<h3>What is the function of Antisense Gene ?</h3>
Antisense RNAs play the crucial role in regulating gene expression at multiple levels, such as at replication, transcription, and translation.
- In addition, artificial antisense RNAs can effectively regulate the expression of related genes in host cells.
- Antisense gene therapy is a gene silencing technique similar to RNA interference, but uses a slightly different mechanism.
- The therapy is called a gene silencing technique because, instead of repairing the gene, it aims to “silence” the gene's effect.
