Answer:Acids and bases In the human body, both blood and the cytosol (watery goo) inside of cells have pH values close to neutral. ... A base, in contrast, raises pH by providing hydroxide (OH −start superscript, minus, end superscript) or another ion or molecule that scoops up hydrogen ions and removes them from solution.
Explanation:
- In the mRNA; A will be complementary to U
- In tRNA; U will be complementary to A
The mutation does not affect the structure of the protein and is called a silent mutation.
<h3>What is a mutation?</h3>
A mutation is a change that occurs in the sequence of nucleotides of a gene.
The mutation that changes the base G in the DNA to A will result in the following corresponding changes in the mRNA and tRNA:
- In the mRNA; A will be complementary to U
- In tRNA; U will be complementary to A
The mutation does not result in any changes since the amino acid coded for by the mRNA has more than one codon coding for it.
This type of mutation is called a silent mutation.
In conclusion, some mutations occurring in genes have no effect on the proteins the gene codes for.

Answer:
The answer is D.
Explanation:
Reproductive isolation is where a species can't breed with any other species except its own.
Most lipids are <u>nonpolar</u>. This property causes lipids to be <u>water-insoluble</u> in the bloodstream. Lipoproteins form <u>water-soluble </u>complexes for transport through the bloodstream by surrounding <u>nonpolar</u> lipids with <u>polar </u>phospholipids and proteins .
A central hydrophobic core of non-polar lipids, predominantly cholesterol esters and triglycerides, makes up the complex particles known as lipoproteins. Since lipids like cholesterol and triglycerides are not soluble in water, they must be carried in the bloodstream along with proteins called lipoproteins.
These lipoproteins are essential for the small intestine to absorb and transport dietary lipids, for lipids to travel from the liver to peripheral tissues, and for lipids to travel from peripheral tissues to the liver and intestine.

Answer:
Your lungs are part of the respiratory system, a group of organs and tissues that work together to help you breathe. The respiratory system's main job is to move fresh air into your body while removing waste gases
