Photosynthesis<span> is a process used by plants and other organisms to convert </span>light<span> energy into </span>chemical energy<span> that can later be </span>released<span> to fuel the organisms' activities (</span>energy transformation<span>). This chemical energy is stored in </span>carbohydrate molecules<span>, such as </span>sugars<span>, which are synthesized from </span>carbon dioxide<span> and </span>water<span> – hence the name </span>photosynthesis<span>, from the </span>Greek φῶς<span>, </span>phōs<span>, "light", and </span>σύνθεσις<span>, </span>synthesis, "putting together".<span>In most cases, </span>oxygen<span> is also released as a waste product. Most </span>plants<span>, most </span>algae<span>, and </span>cyanobacteria<span> perform photosynthesis; such organisms are called </span>photoautotrophs<span>. Photosynthesis is largely responsible for producing and maintaining the </span>oxygen content<span> of the Earth's atmosphere, and supplies all of the organic compounds and most of the energy necessary for </span>life on Earth<span>.</span>
Answer:
Mitosis takes place in four stages: prophase (sometimes divided into early prophase and prometaphase), metaphase, anaphase, and telophase.
Explanation:
Answer;
B. Placing used needles in a sharps container.
Explanation;
-Engineering controls are practices which would lessen if not eliminate the exposure of a human being to chemical and other physical hazards by using or substitution of engineered machinery or tools.
-Engineering controls are methods that are built into the design of a plant, equipment or process to minimize the hazard. Engineering controls are a very reliable way to control worker exposures as long as the controls are designed, used and maintained properly. The basic types of engineering controls are:
process control, enclosure and/or isolation of emission source, ventilation.
