Produces lightning in a thunderstorm

balandron [24]

Answer:

Lightning is an electric current. Within a thundercloud way up in the sky, many small bits of ice (frozen raindrops) bump into each other as they move around in the air. All of those collisions create an electric charge. After a while, the whole cloud fills up with electrical charges.

Compare and contrast photosynthesis and cellular respiration (include the balanced chemical reactions). Include two similarities

muminat

Answer:

Photosynthesis and cellular respiration both are a part of carbon cycle.

Explanation:

<u>Photosynthesis & cellular respiration differences:</u>

(1) Photosynthesis is an anabolic process whereas cellular respiration is a catabolic process.

(2) Photosynthesis uses carbon dioxide and water as substrates to produce glucose as product and oxygen as byproduct.

The balanced chemical reaction for photosynthesis is mentioned as under:

Sunlight

6CO₂ + 6H₂O ---------------------> C₆H₁₂O₆ + 6O₂

(Carbon dioxide) (Water) (Glucose) (Oxygen)

In contrast to photosynthesis, cellular respiration uses glucose and oxygen as substrates and produces carbon dioxide and water as products.

Balanced chemical reaction for cellular respiration is mentioned as under:

C₆H₁₂O₆ + 6O₂ -------------> 6CO₂ + 6H₂O + Energy (ATP)

(Glucose) (Oxygen) (Carbon dioxide) (Water)

<u>Photosynthesis & cellular respiration similarities:</u>

(1) Both of them are type of biochemical reactions which require enzymes.

(2) Both of them require exchange of gases.
