a 25% of sodium chloride will cause the cell to burst from c.membrane. answer is b.
Answer:
30% Thymine
Explanation:
If 30% of Adenine is present, it would be reasonable to assume that 30% of Thymine will be present, as the ratio between the two complementary nitrogenous bases will be roughly equal.
Therefore, that leaves us with 40% between Cytosine and Guanine. Since the ratio between them would be equal, it gives us 20% of Cytosine and 20% of Guanine.
<u>Therefore:</u>
30% of A + 30% of T + 20% of C + 20% of G = 100% DNA
The answer would be "<span>aspiration".</span>
Answer and explanation:
Cystic fibrosis occurs due to mutations in the CFTR gene, causing deficient ion transport in patients through cell membranes with a reduction in the amount of water from bronchial secretion.
This decrease makes the secretion more adherent to the bronchial walls and compromises the cleaning of these channels, facilitating pulmonary infections.
The disease also causes the blockage of the pancreas ducts, reducing the arrival of digestive enzymes in the intestines.
For an individual to develop cystic fibrosis by mutations, it is necessary to have both chromosomes 7 with the mutated CFTR gene. This means that a person needs to inherit mutated chromosome 7 from his mother and father.
