NUCLEAR ENERGY
Every second of every day our Sun converts about 4.2 million metric tons (4,200,000,000 kilograms) of hydrogen into helium using a nuclear <span>fusion </span>process. During this nuclear reaction, a small portion of matter is converted to an enormous amount of energy. It is this output that provides the energy for photosynthesis and for heating our atmosphere and oceans.
In this lesson, you will learn the details of the nuclear fusion process. You will also learn about another important nuclear reaction called fission and some useful applications of it.
OBJECTIVES<span>Describe the process of nuclear fusion.Describe the process of nuclear fission.Identify some applications for nuclear reactions.List positive and negative factors associated with nuclear reactions.</span><span>VOCABULARY</span>
The citrus fruits are a good source of vitamin C.
The dark green leafy vegetables also have many important vitamins and minerals. They are an abundant source of vitamin C, A, K as well as (folate vitamin B9). Other than these, they also provide iron and calcium. The dark green leafy vegetables are also a great source of fibres. But, they are not very good source of ZINC or selenium.
hence, the correct answer is option A. Vitamin
C. They both have cell membrane
Answer:
145 degrees F
Explanation:
To prevent contamination and food borne infections, raw beef, pork, lamb and veal steaks, chops and roasts must be cooked to a minimum of 145°F internal temperature before being removed from heat source.
This minimum temperature reading will annihilate traces of food borne pathogens in the food and make it safe for consumption.
<span>Cellular respiration is a set of metabolic reactions and processes that take place in the cells of organisms to convert biochemical energy from nutrients into adenosine triphosphate (ATP), and then release waste products.
