Over a vast amount of time, millions of years, the earth gradually cooled. When the temperature dropped enough, water vapor condensed and went from a gas to liquid form. This created clouds.
Before life began on the planet, Earth's atmosphere was largely made up of nitrogen and carbon dioxide gases. After photosynthesizing organisms multiplied on Earth's surface and in the oceans, much of the carbon dioxide was replaced with oxygen.

Answer:
Enzymes are proteins.
cloning an individual usually produces organisms that
animals of the same general body types have the same anatomy true or false
Animals of the same general body types having the same anatomy is True.
Anatomy is the study of the body parts, structures and functions of
organisms.
In situations where animals have the same general body type , then it means
they also have the same anatomy. A good example is mammals which have
the same structure of body parts and the same anatomy.
Organisms with different body structures however have an entirely different
anatomy which is why True is the most appropriate choice.

How does carbon atom work on plants
Answer: Carbon moves from the atmosphere to plants. In the atmosphere, carbon is attached to oxygen in a gas called carbon dioxide (CO2). Through the process of photosynthesis, carbon dioxide is pulled from the air to produce food made from carbon for plant growth.This energy makes carbon molecules an excellent source of fuel for all living things. During photosynthesis, plants absorb carbon dioxide and sunlight to create fuel glucose and other sugars for building plant structures. This process forms the foundation of the fast (biological) carbon cycle.
