What is natural selection? How does this work on organisms in nature? (should be at least 3 sentences)

Biology
1 answer:
BigorU [14]3 years ago
4 0

Answer:

The natural selection is a theory made by Charles Darwin where animals better adapted to their environment tend to survive and produce offspring. for example, there are about 50% of beetle that are green and 50% orange.  If crows tend to eat green beetles more, there will be more orange beetle to produce offspring so there wood then be less green beetles to be eaten by crows.

An environment can change over time and this will cause for the animals living in the environment to adapt as well. These changes will occur when an animal with undesirable traits don't survive to reproduce. The offspring of individuals that do survive to reproduce will inherit their parent's desirable traits. Over many generations, the desirable traits will be seen in more-and sometimes all- of the individuals in the population

Explanation:

That is the natural selection told in my words, but please do your best to rewrite your own sentence/paragraph. Copying another's work is called plagiarism and any teacher can automatically give you a 0% for this.

Anyway, goodluck.

Why are flood plain soils particularly fertile
kvasek [131]

Answer:

Due to the deposition of silt.

Explanation:

The Floodplain is a generally flat area of land next to a river or stream. When the river floods, water containing sediments and particles from the upper course and middle course of the river gets washed onto the Floodplain. The nutrients front these sediments and the water is absorbed into the soil for it's enrichment and fertilisation.

Describe how advances in DNA technolgy are assisting the work of those in medical fields
shutvik [7]

Answer:

Advances in DNA technology have allowed for treatments such as gene therapy in the medical field. Nowadays, there are tools like the CRIPSR-Cas9 - harnessed from bacteria's immune system- that can nip a ‘bad’ region of DNA, which is responsible for disease, and replace it with a proper functioning bit. This is how genetic disorders are going to be addressed in the near future in mainstream medical facilities.

Recombinant DNA technology is being used to create clones of transgenic organisms that produce products of significance in the medical fields. An example is incorporating the insulin gene in bacteria genome. These clones of modified bacteria colonies secrete insulin protein that is purified and injected in diabetic persons to lower their sugar level to normal.

If a mutation results in an organism with new characteristics, what might eventually be formed?
Temka [501]

If a mutation results in an organism with new characteristics then eventually a new species will be formed if more such mutations will continue to accumulate in the individual. Mutations result into the accumulation of variations in an individual and when such variations keep on accumulating in a particular organism consistently it leads to formation of a new species or we can say that evolution has occured.

What are the only types of mutations that matter to large-scale evolution?
hoa [83]

Answer:

The only types of mutations that matter to large-scale evolutionary species are the mutations that can be passed to offspring (Genetic).

Explanation:

If a mutation is passed to offspring, through the generations it will become more and more prevalent...Eventually causing a pretty good dent on a population size. Hope this helps : )!

Explain why it is that translation cannot happen, unless transcription happens first.
Aleks [24]

Answer:

Translation uses DNA as a template to direct the synthesis of a RNA which in turn serves as a template for Translation which template is used to direct the synthesis of a polypeptide chain.

Without transcription, there will not be a mRNA strand to act as a template for translation by the ribosomes to occur at all.
