Answer:

POINT MUTATION (SUBSTITUTION)

Explanation:

A point mutation is that mutation which involves only one nucleotide base. Point mutation can, however, occur in different ways such as SUBSTITUTION. Substitution point mutation is that which involves the replacement of a single nucleotide base by another in a gene sequence.

This is the case in this question regarding the mutation that causes sickle cell anaemia. According to this question, Sickle cell anemia is a disease that occurs when a mutation in the base pair of the hemoglobin beta gene causes a SINGLE replacement of GLUTAMIC ACID (Glu) by VALINE (Val). This shows that it is a type of SUBSTITUTION POINT MUTATION.

True or false all changes in genes due to mutations are not beneficial
Troyanec [42]
False, changes in genes due to mutations can be beneficial. (An example would be polar bears. They had a genetic mutation that gave them their white fur. Therefore, they blended in with snow easier, ate more food, survived longer, and passed down their genetics, while those without the mutation died out.)

Here is a diagram of the digestive system. Where do you think lactase would be most effective? Explain. Be sure to consider the
BartSMP [9]

Lactase will most likely be found in the small intestine and food spends the largest time there.

The digestive system refers to all the structures that are responsible for the breakdown of food in the body. In each part of the digestive system, enzymes act on the food particles to enable certain conversions.

The enzyme lactase in involved in the digestion of milk and diary products. The enzyme has an optimum pH of about 6 hence it works in an acidic environment. Lactase is found in the small intestine.
