Answer:
Hershey and Chase demonstrated that genetic material is contained in the DNA molecule. By using bacteriophages they observed that DNA, but not proteins, contains the genetic material. These researchers tagged DNA with radioactive phosphorus and then separated bacteria and protein phages by centrifugation, observing that bacterial pellet was radioactive
Answer: Protons and electrons are far apart with lots of empty space in between.
Explanation:
Atom is defined fundamental part of a matter. Atom is composed of three sub particles protons, electrons and neutrons.
In an atom, electrons are located in orbits around the nucleus. Nucleus of an atom is located at center of the atomic sphere where protons and neutrons are present. Hence, it will be correct to say that "protons and electrons are far apart with lots of empty space in between".
The answer to this question would be: <span>during pregnancy
Body metabolic rate will be increased during pregnancy because the mother needs to supply the child needs too. In reduced-calorie diet, the body will adapt to the hunger by lowering the basal metabolic rate. The basal metabolic rate also will be decreased as we age and when we are sleeping.</span>
The carbon cycle moves through virtually all of the earth's spheres.
<h3>Carbon cycle</h3>
There are 4 majors spheres of the earth:
- Atmosphere
- Geosphere or Lithosphere
- Biosphere
- Hydrosphere
The carbon cycle moves through the air (atmosphere), oceans (hydrosphere), organisms (biosphere), and the soil (geosphere).
Thus, the carbon cycle moves through all the spheres of the earth.
