How do building dams for electricity affect ecosystem someone please help me please

Answers

Answer 1

Answer: The first effect of a dam is to alter the pattern of disturbances on which the plants and animals of a river depend. Many aquatic animals coordinate their reproductive cycles with annual flood seasons. Every flood is valuable in that it takes nutrients from the land and deposits them in the river, providing food for the stream's residents. Floods also provide shallow backwater areas on vegetated and shaded riversides; the young of many animals depend on these backwaters to protect them from predators too large to swim in these shallow waters.

Describe the flow of blood through the human body, including through each of the four chambers of the heart. Explain how the blood changes as it moves through various locations in the body.

Answers

Unoxygenated blood from veins enters the right atrium then it goes down to the right ventricle then out through the pulmonary artery to the lungs where it becomes oxygenated blood which then enters the heart through the pulmonary veins and it goes to the left atrium and then is pumped down to the left ventricle and out through the aorta to the arteries where it travels to different organs and becomes deoxygenated and then the cycle repeats itself.

a substance that moves across a cell membrane without using the cells energy tends to move?

a.) away from the area of equilibrium

b.) away from the area where it is less concentrated.

c.) away from the area where it is more concentrated

d.) toward the area where it is more concentrated

Answers

Answer: The correct option is C.) away from the area where it is more concentrated.

A substance that moves across a cell membrane without using the cells energy tends to move from an area of high concentration to an area of low concentration.

This is known as Passive transport. In this transport, substances move down the concentration gradient i.e from an area of high concentration to an area of low concentration. It is also called simple diffusion as no energy is required in this process.

C because this is passive transport and not using any energy. Passive transport is where a substance is moved from high concentration to low concentration.
