Answers

Answer:

High tides and low tides are caused by the moon. The moon's gravitational pull generates something called the tidal force. The tidal force causes Earth—and its water—to bulge out on the side closest to the moon and the side farthest from the moon. ... When you're not in one of the bulges, you experience a low tide.

List the characteristics of life that plants and animals in a food web share

Answers

Answer:They are movement, nutrition, respiration, sensitivity, reproduction, excretion,and growth.

Explanation:

Matter are anything that is made up of atoms. The quantity of matter can be observed only on the basis of mass and volume calculation. Thus, movement, nutrition, respiration, sensitivity, reproduction, excretion and growth are  the characteristics of life that plants and animals in a food web share.

What is matter?

Matter is a substance that has some mass and can occupy some volume. The matter is mainly used in science. Matter can be solid, liquid or gas.

So as we saw that matter has some mass so mass can be measured in gram only. Mass can also be represented as number of molecules. We also saw that matter occupy some volume and that volume is measured only in liter. Movement, nutrition, respiration, sensitivity, reproduction, excretion and growth are  the characteristics of life that plants and animals in a food web share.

Thus, movement, nutrition, respiration, sensitivity, reproduction, excretion and growth are  the characteristics of life that plants and animals in a food web share.

Answers

Answer: Gamma rays
Explanation: They are used to kill the dead cells from e.g. cancer but they don’t destroy the living cells as gamma is only a wave.

Among electromagnetic waves, UV rays are most dangerous because exposure to these radiation cause serious problems in living organism. Therefore, gamma rays is used carefully in medicine without damaging living tissue.

What is electromagnetic wave?

Electromagnetic wave is a wave which contain two component one is electric component and other is magnetic component. The electric and magnetic component are perpendicular to each other. There are so many wave that comes under electromagnetic wave like infrared wave , radio wave.

There is a relation between energy of wave. frequency of wave, and wavelength of wave

Mathematically,

E=hc/λ

where,

E = energy of electromagnetic wave

h is planks constant having value 6.67×10⁻³⁴js

c is speed of light that is 3×10⁸m/s

λ is the wavelength of electromagnetic wave

There are many uses of electromagnetic radiations in medical field. Gamma rays are used to kill the dead cells from e.g. cancer but they don’t destroy the living cells as gamma is only a wave.
