Answer : Photosynthesis is an example of a chemical reaction.
Explanation :
Photosynthesis : It is a type of chemical process which takes place in the plant cell. In photosynthesis process, the light energy converted into the chemical energy.
As plant needs carbon dioxide, water and light. During the photosynthesis, carbon dioxide, water and sunlight react to gives glucose, oxygen and water as a product.
The balanced reaction of photosynthesis will be,
Hence, photosynthesis is an example of a chemical reaction.
Answer:
Fossil record gives evidence of evolution: Earliest land animals. A fossil called Tiktaalik has been found to be halfway between a fish and the earliest land animals
Explanation:
Fossil record documents the hystory life by fossils that have been found in the sedimentary rock layers
The fossil record matches the geologic record:
The oldest forms of life were much more simple than the newest forms of life.
Explanation:
The geologic record can be associated with sedimentary datable layers

Answer: Kinetic is moving potential means its a possibility it will move
Explanation:
A star's apparent brightness<span> is its </span>brightness<span> seen from Earth. A star's </span>absolute brightness<span> is the </span>brightness<span> the star would have if it were at a standard distance from Earth
</span>so if your riding in a car at night and your passing some one on the road in there point of view your apparent brightness is lets say 10 and if your are farther a way your estimated brightness or star's absolute brightness would be 10.<span />
Answer:
pressure of the gas inside the lungs will be =1.35 atm
Explanation:
so for calculation of pressure of gas we will use the formula
(remember to convert *C to kelvin)
PV₁/T₁ = P₂V₂/T₂ As we know that Temperature = 310.5 k =37 degree
so for pressure P₂
P₂=P₁V₁T₂/T₁V₂
= ((1.00atm)(2.20L)(310.15K))/ ((298.15K) (1.70L)
=1.35 atm
(remember to convert *C to kelvin)
