Answer:
salt
Explanation:
if water has salt it is no longer considered fresh, rather it is salt water
Glycogen is a polysaccharide useful for energy storage in the body. It is easily confused with starch. Actually, both are mostly similar. However, the most distinct difference is that glycogen is for humans and animals, while starch is for plants. Hence, the answer is <span>a polysaccharide found in animals.</span>
In the next decade, the gene coding for green eyes in hares may have increased in proportion in the hare population, it may have decreased, or it may have been completely eliminated from the population. This will happen completely randomly.
We can arrive at this answer because:
- Genetic drift is an evolutionary mechanism that can act together with natural selection.
- While natural selection allows the most adapted genes to be passed on to the next generation, genetic drift does not have a criterion, and genes are passed through generations in a completely random way.
- Thus, according to the genetic drift, the next generations can receive the adaptive gene in greater quantity, smaller quantity, or not receive, causing a trait to be removed from the population in a completely random way.
Therefore, we can say that it is not possible, through genetic drift, to know what will happen to the green-eyed genes in hares, as they can increase, decrease or disappear from the population.

Answer:
The correct answer is: Gain-of-function mutation.
Explanation:
- Mutation can be defined as the sudden alteration in the sequence of DNA or Deoxyribonucleic Acid, which if happens in the protein-coding region of the gene can cause the protein to become non-functional or can change the function of the protein.
- If such a mutation happens in the untranslated region or the regulatory sequence of the gene, it can cause:
- the gene to get constitutively (all the time) expressed at high levels, such that its expression can no longer be regulated or controlled. This type of mutation is called a Gain-of-function mutation.
- the expression of the gene to get repressed or suppressed, such that very less amount of protein or no protein that is encoded by the gene is produced. This type of mutation is called a Loss-of-function mutation.
