Mutations are changes that occurs in our DNA sequence, either due to mistakes when the DNA is copied or as the result of environmental factors such as UV light and cigarette smoke.

They increase the genetic variation within a species because they can create entirely new alleles in a population, random mating, random fertilization, and recombination between homologous chromosomes during meiosis which reshuffles alleles within an organism's offspring.

HOPE THIS HELPS :)

Answer:

Capsule

Explanation:

In many bacterial species, an extracellular layer composed of a polysaccharide especially a monosaccharide is produced around the cell wall of the bacteria. This extracellular layer is known as the slime layer or the capsule.

The capsule in bacteria serves many purposes like it protects the bacteria from the destruction by the white blood cell in the host, it enables the bacteria to adhere to the substrates and protect it.

In the plant group called the bryophytes also a capsule structure is present which grows in the sporophytic phase and encloses the spores, therefore, the capsule is considered the sporangium of the bryophytes.

Thus, the capsule is correct.

Answer:

The final volume is the sum of the initial volume and the volume of the object.

Explanation:

Since we know that the volume of the object is the difference between the final and the initial volume, let the volume of the object be ∆V, let the initial volume be V1 and let the final volume be V2.

From;

∆V= V2 - V1

V2= ∆V + V1

Hence the answer above
