How does artificial selection provide evidence for evolution by natural selection

Biology
1 answer:
Cloud [144]3 years ago
5 0

Answer:

Natural selection is one of the mechanisms by which an organism evolve. In the natural selection when the trait of an organism allows the organism to grow and reproduce in an environment and nature selects it, it is then passed on to the generations and become permanent.

Artificial selection is also one of the mechanism of evolution in which instead of nature, the selection is made by humans like the breeding experiments on dogs and plant crops.

The artificial selection and natural selection are interlinked as in the artificial selection the trait selected by the humans were also selected by nature like the case of crops, the crossing between desired plants produced results which were useful to the humans but grew and reproduced only when the environment selected it to grow and reproduce.

The dominant allele is D and causes dimples and the recessive allele is d and causes no dimples. How would a geneticist describe
SSSSS [86.1K]

A geneticist describes the phenotype of an individual with the alleles dd as homo-zygous recessive. In heterozygous individuals, it is masked by the dominant allele.

<h3>Dominant and recessive alleles</h3>

In diploid organisms, an individual receives two gene forms or 'alleles' for the same gene locus.

An individual is heterozygous when receives two different alleles for the same gene locus, whereas an individual is homo-zygous when receives the same alleles for a gene locus.

In cases of complete dominance, the dominant allele completely masks the recessive allele in heterozygous individuals.

What are the benefits of plants living on land rather than in water?
zzz [600]

The protoplasm and cytoplasm of a plant are interchangeable terms.TrueFalse
Svetllana [295]
No, they are not interchangeable because p<span>rotoplasm is the living content of a cell that is surrounded by a plasma membrane (cell membrane). Protoplasm is composed of a mixture of small molecules such as ions, amino acids, monosaccharides and water, and macro-molecules such as nucleic acids, proteins, lipids and polysaccharides. In eukaryotes the protoplasm surrounding the cell nucleus is known as the cytoplasm and that inside the nucleus as the nucleoplasm. </span>

What happens to the rate of photosynthesis as the intensity of light or concentration of CO2 increases? And How is your conclusi
NikAS [45]

Answer:

The rate of photosynthesis increases the intensity of light or concentration of CO2 increases, however, at a certain temperature, the rate can decrease due to enzyme denaturation.

Explanation:

Photosynthesis is a unique metabolic process specific to only some organisms. The photosynthetic process, however, cannot occur without some vital ingredients including light, Carbon dioxide (CO2) and optimum temperature.

An increase in the concentration of light (from sun) and CO2 (from atmosphere) increases the rate at which photosynthesis occurs i.e. more light, CO2 results in more photosynthetic process. However, an increase in TEMPERATURE also increases the photosynthetic rate but at a particular temperature, the enzymes that bring about the photosynthetic process can be denatured or damaged, hence, at an EXCESSIVE TEMPERATURE, photosynthesis can be inhibited.
