How could natural selection lead to evolution?

Biology
1 answer:
daser333 [38]2 years ago
8 0

Answer:

Natural selection is a process where organisms that are better adapted to an environment will survive and reproduce.

Explanation:

This means that the advantageous alleles of this variant organism are passed on to offspring. Over many generations, the process of natural selection leads to evolution occurring.

Which mutations is most likely to cause a phenotypic change?
melomori [17]

The question is incomplete. The complete question is as follows:

Which of the following mutations is most likely to cause a phenotypic change?

A) a duplication of all or most introns

B) a large inversion whose ends are each in intergenic regions

C) a nucleotide substitution in an exon coding for a transmembrane domain

D) a single nucleotide deletion in an exon coding for an active site

E) a frameshift mutation one codon away from the 3' end of the nontemplate strand

Answer: D) a single nucleotide deletion in an exon coding for an active site

Explanation:

Deletion or insertion of a single nucleotide in an axon coding for an active site is called frameshift mutation.

The sequence of codons is read during translation, in order to synthesize a amino acids chain and form a protein from the nucleotide sequence. Frameshift mutations occur when the usual codon sequence is broken by the deletion or addition of one or more nucleotides. For example, if only one nucleotide is removed from the axon sequence during the RNA splicing process, then there will be a disrupted reading frame for all codons before and after the mutation. This may result in several incorrect amino acids being introduced into the protein. Disruption in protein sequence will cause phenotypic change.

Hence, the correct option is D) a single nucleotide deletion in an exon coding for an active site .

What does she need from the food she ate and the air she breathes so that she can go on her run? How do Rosa's body systems work
IgorC [24]

The missing part of the question is as follows:

Rosa eats a peanut butter sandwich for lunch. Peanut butter contains a lot of protein, and bread is mostly starch. Rosa plans to go for a run later this afternoon. Rosa is breathing normally.

Answer:

1. The food she ate is peanut butter and bread, the peanut is rich in protein while the bread is rich in carbohydrate which provides sugar (glucose) by breathing she gets oxygen in a sufficient amount to perform cellular respiration (aerobic) to carry out energy for running. Carbohydrates are a better choice of nutrients befors exercise as carbohydrates provide energy immediately.

Aerobic respiration provides a high amount of energy, 36 ATP to be specific, per cycle of cellular respiration.

2.  The carbohydrates (glucose) and oxygen she gets from food and breathing react together to perform aerobic cellular respiration to carry out maximum energy. By the digestive system and organs of this system, carbohydrates are broken down into glucose which is diffused into the blood.

Oxygen also diffused to blood from the lungs and heart with the help of the respiratory and cardiovascular systems of her body.

3. By the aerobic cellular respiration process takes place in the mitochondria of the cell helps in providing energy from glucose and oxygen by a three-step process:

Glycolysis, the Krebs cycle, and oxidative phosphorylation. Here glucose reacts with oxygen. Which ultimately provide 36 ATP molecules for the cell in a run.
