Answer:
Sun(solar energy)
Explanation:
The sun is the ultimate source of energy in our solar system.
The chemical energy in plants all started out with solar energy from the sun.
During the process of photosynthesis;
- green plants manufactures their food using sunlight.
- in the presence of this solar energy, they combine carbon dioxide and water to produce glucose and oxygen.
Photosynthetic reaction simply converts solar energy from the sun into chemical energy.
Almost all animals obtain their own energy needs from the plants converting the chemical energy into other forms of energy.
I dont think so, photosynthesis requires light to carry out.
"Contaminated hospital equipment represents a difficult environment to control harmful microbial growth. Regarding influences that affect disinfection of hospital equipment, which of the following is an accurate statement?
- Biofilms, often found contaminating hospital equipment, are relatively simple targets for biocides to reach effectively.
- The presence of organic matter, such as dried blood or protein, will not affect the action of antimicrobial agents.
- Antimicrobial agents work best under reduced temperatures.
- The cell walls of gram-negative bacteria are especially resistant to many chemical that are used to destroy microbes.
"
Biofilms are extracellular matrix formed by organisms. They are slimy and are used to attach to surfaces. They are made of polysachharides and form a barrier of protection against disinfectants. Therefore, they make it difficult to decontaminate surfaces.
Organic matter like dried blood or protein also affect the action of antimicrobial agents. Organic matter may form a layer that would reduce the access of the disinfection to the organism.
Antimicrobial agents are affected by temperature and have optimum temperature of action. Some get denatured by heat while some are unaffected. The temperature an antibiotic works will also depend on the organism and its mode of action.
Gram negative bacteria have shown resistance to more antimicrobials.
It is known as ISCHEMIA.
Ischemia occur when there is an hindrance in the flow of blood to a particular organ in the body. Because it is the blood that carry oxygen round the body, such an organ will not get adequate supply of oxygen. Ischemia is usually caused by blockage or narrowing of the arteries.
Im pretty sure your answer is b.
