would know that a cell under microscope is prokaryote because it lacks nucleus
cells. Prokaryote is a single celled organism. It’s cell structure is composed
of flagellum, cell membrane, cell wall, cytoplasm, ribosome, nucleoid, and
glycocalyx. Flagellum’s function is to aid cellular locomotion but is only for
selected types of prokaryotes. Cell wall covers the outer part to protect the
bacteria cells. Nucleid is the area that contains the DNA of the bacteria. Cell
membrane regulates the flow of the substances in and out of the cell. Cytoplasm
contains salts and other organic molecules. Ribosomes is responsible of protein
production.</span>
Answer:
Evolution occurs when nature selects <u>mutation that increase reproduction.</u>
Explanation:
- 'Survival of the fittest', this is the major principle followed in the process of Natural selection.
- This explains that nature will select only those individual who are fitter than rest of the population.
- A more fit individual will show a greater reproductive success.
- A greater reproductive success can be attained by a mutation that increases reproduction.
- Thus population of such individual prove itself to be more fit to maintain its population and gene pool.
- Soon the population with lower reproductive success will be eliminated and the evolved population with greater reproductive success will stabilize as a result of Natural selection.
- Thus, Evolution takes place when Nature selects Mutation that increase reproduction.
It creates more cells and keeps a cell from becoming too large. Please mark Brainliest!!!
Answer:
Genes aren't eradicated from natural selection, but the chances of getting the phenotypes (the physical attributes of an organism based on the genes) go down as the organisms with those phenotypes die out.
Explanation:
Recessive genes are still present in, for example, a heterozygous genotype. but since there is a dominant, it covers the recessive gene and the phenotype won't have anything to do with the recessive gene (unless we are talking about incomplete or codominance).
