The biodiversity will decrease due to an increase in pollution is the effect will have on the biodiversity on the river ecosystem.
Option A
<u>Explanation:</u>
Biodiversity is the actual collection of total amounts of flora and fauna present in a particular ecosystem. The river ecosystem consists of the aquatic plants, the aquatic animals like fishes,etc and even the surrounding land plants and animals, who utilize the river water for their living.
The inclusion of the polluted sewage of the surrounding area into the river directly mixes several chemicals to the water, which are potentially harmful for all the animals living there. This leads to destruction of the flora and fauna of both water and lands surrounding them. This hampers the biodiversity of the water as well as surrounding land.
I think this is actually a physics question-
gravitational potential energy = mass*g*height. We know mass and g is constant, so all we need to know is the height of the basketball.
Hope this helps :)

Answer:
Lightning
Explanation:
The term plasma referred to that condition when the electrons are "freed" from their host atoms for a short time. It happens due to the high temperatures.
Lightning is a plasma because when a column of electrons moves from sky to ground, the air that it passes through lights up with energy. What we see as lightning is the air. In this air, the electrons are excited and giving off light. We see it as a light.
From this brief discussion, we can say that as electrons become free and become excited and then give light, lighting is a plasma.
Answer:
<em><u>The diaphragm muscle contacts and relaxes to force the intake and expulsion of air from the lungs.</u></em>
Explanation:
The diaphragm is a large, dome-shaped skeletal muscle. It is very thin, and is located at the base of the chest just above the abdomen.
It plays a very important role during respiration or breathing by forcing the intake and expulsion of air from the lungs.
During inhalation, this muscle contracts, and flattens- in the process, a vacuum is created, effectively pulling air into the space. In exhalation the muscle relaxes, and is no longer flattened, this reduces the volume of the region, forcing air out of the lungs.
These contractions occur rhythmically and continuously.
