Answer:
Chemical properties of water are neutral pH and weak ionization while physical properties of water are that it is present in solid , liquid and gas form and it is a tasteless and odorless molecule.
Explanation:
Water is also called universal solvent due to its polar nature. Water has a neutral pH when it is present in pure form but with the addition of salts and other impurities, pH of water changes. Water has weak ionization rate. Water is present in liquid form at room temperature but increasing in temperature , they transform in gaseous state.. Water is a taste less molecule and having no odor or smell.
B. "the nameless grace/Which waves in every raven tress" is correct.
Answer
Volume. Just think about it, do any of the others make any sense?
Frequent inbreeding within a species can result in extinction of the species. The recurring set of available genes during reproduction allows for decreased genetic diversity.
Answer:
The beneficial role of antibiotics in the human body is given because they produce rupture the cell wall or prevent protein synthesis in bacteria.
Explanation:
Antibiotics are a group of drugs that fight bacteria, eliminating them, to cure infectious diseases.
The mechanisms of action of antibiotics aim to break the bacterial protection or interfere with their vital functions to make them unviable:
- Destruction of the bacterial wall or membrane.
- Interference with protein synthesis.
- Inhibition of the synthesis of nucleic acids.
In general, the effects of antibiotics on bacteria are to rupture the cell wall or prevent protein synthesis. Through these mechanisms, antibiotics eliminate and prevent the reproduction of pathogenic bacteria, thus eliminating the infections they produce.
The other options are not correct because:
<em> a. Breaking down damaging toxins created by bacteria is an anti-toxin function.</em>
<em> b. Antibiotics do not increase the number of white blood cells in the blood. </em>
<em> d. Reduction of the effects of fever, swelling, and inflammation in the body is a function of antipyretics and anti-inflammatories.</em>
