Answer:B. Insertion

Explanation: Mutation can be defined as a permanent change in the nucleotide sequence of a DNA. There are basically three types of mutation: insertion, substitution or deletion. Insertion is a type of mutation in which one or more base pairs is added to a nucleotide sequence of a DNA. Substitution involves the replacement of one base pair with another in a nucleotide sequence of a DNA while deletion involves the total removal of one or more base pairs in a nucleotide sequence. A mutation can be silent if it affects non coding segments of a DNA or if it has negligible effect on the gene function, but most times mutations are deleterious.

iris [78.8K]

Answer:

The phylum Hemichordata is the one that could form an evolutionary connection between the chordates and non-chordates.

Explanation:

To the phylum Hemichordata belongs a genus that scientists believe could explain how the chordates could evolve from the non-chordates. This genus is Balanoglossus, of the class Enteropneusta.

Balanoglossus is similar to a worm, whose habitat is the seabed, and like other hemicordates it has a stomach, a structure that forms part of its digestive system and fulfills the functions of a spine.

Explanation;

Hot Desert is characterized by very little rainfall or a lot of rain in a very short period. The soils are often salty because minerals do not get washed away. Thus, the climate is characterized by a very little precipitation.

-Plant adaptations: There are few plant species. these plants are adapted to resist drought and store water. For example; Spiny cacti that have thick, fleshy stems that conserve water are common. Their roots extend metres away from the plant to absorb water. Other plants have small, thick, waxy leaves that also store water. Many plants have spines or produce chemicals that protect them from being eaten.
