To answer the question that is: "which factors affect a river's load", we have to understand that all the things mentioned are important. All these options (river's slope, streambed shape and volume of flow) affect the amount of energy that the river has to spend and the way the river spend that energy, so, it is right to mark the alternative d) all of the above.
Answer: They limited the rights and freedoms of African Americans.

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.

Answer:
<u>the bottleneck effect</u>
<u />
Explanation:
Genetic drift has an important impact on the small populations. mutations, which are spontaneous heritable changes in the genetic code, made up of DNA. Here, mutations accumulate over time in a group, modifying the distribution of alleles or various forms of a gene. Natural selection may result in a loss of diversity in a population called genetic drift; one trait's allelic frequency rises while others become less prevalent. Typically such differences exist because of occurrences of mutation and recombination.
Some mutations or alleles may become extinct from the population.
<u />
Variants of a gene accumulate and are transmitted across generations; the frequencies of these occurrences are altered and become more stable in genetic drift- they become genetically distinct and may eventually form a new species after isolation. This may be further compounded through other phenomena such as the founder effect where a group separates and genetic diversity decreases; and the bottleneck effect where barriers to reproduction or the die-off a population increases genetic drift.
