Answer:
A
Explanation:
The pulmonary artery carries de-oxygenated blood from the right ventricle of the heart to the lungs. It is the only artery that carries de-oxygenated blood. This blood is usually from the tissues and has a lot of carbon dioxide from the cellular respiration of cells around the body. The blood is pumped to the lungs to be oxygenated and the carbon dioxide expelled.
The width of the cloud is : 384 m
<u>Given data :</u>
Cloud altitude = 2200 m
Temperature = 10°
<h3>
</h3><h3>Determine how wide the cloud is </h3>
applying the equation below
I = d
where : I = linear size , d = 2200 m , 
therefore :
I = 2200 ( 10 / 57.3 )
= 383.94 m
≈ 384 m
Hence we can conclude that the width of the cloud is : 384 m

Answer:
Algae produces food and catfish also needs warm water.
Explanation:
Sunlight regulates the productivity of algae and the number of catfish in a pool because algae produces food in the presence of sunlight during the process of photosynthesis. If algae produces more food, so more food is available for the catfish and as a result the population of catfish increases. If no sunlight occur on the pool the algae is unable to produce food and the population of catfish decreases. Sunlight increases the temperature of water which makes environment suitable for the catfish because catfish needs slightly warm water for its growth. So we can say that sunlight has a great affect on algae and catfish.
