Answer:
C
Explanation:
Protozoa have been classified into three trophic categories: the photoautotrophs which harness the sun's radiant energy in the process of photosynthesis; the photoheterotrophs, which although phototrophic in energy requirements, are unable to use carbon dioxide for cell synthesis and must have organic carbon compounds
Answer:
The weight of a person on the moon is less, compared to their weight on Earth.
Explanation:
Gravitation is a force. Gravity is the force that tries to pull two objects toward each other.
Anything which has mass, also has a gravitational pull. The more massive an object is, the stronger its gravitational pull is. So because the moon iless massive than the earth, you will experience a less gravitational pull and therefore a you will experience less weight on the moon compared to your weight on earth.
EXTRA
The Gravitational pull is difined by the force that arises of masses of two objects in relation to their distance.
Earth's gravity is what keeps you on the ground and what causes objects to fall back to earth.
You can experience a change in gravitational pull on earth yourself, in an exelerating or decelerating elevator.
There are so many examples for that in different areas, like TPT1 experiment carried out in our lab recently.Here's one link: http://www.alfa-chemistry.com/tpt1-cas-167218-46-4-item-290583.htm
The conservation of forests is vital to our ecosystems, because they provide sustainable amounts of habitat for animals, who live in them. On top of that, forests provide us with a large amount of oxygen. Trees go through photosynthesis, in which they take in carbon dioxide out of our air, and give back oxygen which is vital for all living things. All that being said, conserving trees helps regulate climate control, and overall helps us have healthy ecosystems.
B) The blood of all humans is red based on its organic chemistry.
