Why do you think mutations are necessary for species to change?

1 answer:

8 0

Mutation is the primary cause of all genetic variation. Mutation is important as the first step in evolution, as it produces a new sequence of DNA for a particular gene, producing a new allele. Recombination, through intragenic recombination, may also generate a new DNA sequence (a new allele) for a particular gene.

The mixture of sperm and fluids from the seminal vesicles is called

hichkok12 [17]

Answer:

Semen

Explanation:

Sperm is the male reproductive gamete produced by the testes. During copulation or sexual intercourse, the produced sperm moves along a tube called VAS DEFERENS or sperm duct. The sperm mixes up with fluid called SEMINAL FLUID produced in the accessory glands comprising of seminal vesicles, prostrate gland and the bulbourethral glands to form the SEMEN, which is ejected from the urethra (a tube that runs from the bladder to the penis) during ejaculation.

The seminal fluid that mixes up with the sperm serves to lubricate it for easy locomotion within the female reproductive parts and also provide nourishment for the sperm.

The observation that chloroplasts and mitochondria each contain their own dna and synthesize some of the proteins that function

Sergio039 [100]

The answer to this question relates to the evolution of prokaryotic cells. The first simple prokaryotic cells likely evolved mitochondria from a cell that engulfed an aerobic prokaryotic cell, resulting in<span> an endosymbiotic relationship, and gradual development into a </span>mitochondrion. Something similar happened in regards to chloroplasts, except the original cell engulfed was probably a simple photosynthesising bacteria such as <span>cyanobacteria.</span>
