Answer:
During life activities such as cellular respiration, several chemical reactions take place in the body. These are known as metabolism. These chemical reactions produce waste products such as carbon dioxide, water, salts, urea and uric acid. Accumulation of these wastes beyond a level inside the body is harmful to the body. The excretory organs remove these wastes. This process of removal of metabolic waste from the body is known as excretion.
Answer:
vaporization ,( Evaporation)
The average force exerted by the ball on the glove is 480 N.
<h3>What is the force exerted by the ball on the glove?</h3>
The average force exerted on the glove by the ball is equal in magnitude to the force on the ball.
- Force = mass * acceleration
mass = 145 g = 0.145 kg
Acceleration of the baseball, a = (v² - u²)/2s
where:
v is final velocity = 0
u is initial velocity = 39 m/s
s is distance = -23 cm = 0.23 m
a = (0 - 39²)/2(-0.23)
a = 3306.52 m/s²
Force = 0.145 * 3306.52
Force = 479.4 N
Average force = 480 N
In conclusion, force is derived from the product of mass and acceleration.

<u>Question:
</u>
The law of conservation of mass follows from the concept that a. atoms are indivisible. b. atoms of different elements have different properties. c. matter is composed of atoms. d. atoms can be destroyed in chemical reactions.
<u>Answer:</u>
The law of conservation of mass follows from the concept that atoms are indivisible
<u>Explanation:
</u>
The law of conservation of mass tells that atoms in an object neither can be created nor be destroyed, but they can be transferred around and transformed into various particles. Also, it says that the total mass preceding the chemical reaction corresponds to the total mass after the chemical reaction.
In other words, the mass remains intact. Lavoisier formulated this law as a result of a combustion experiment in which he stated that the weight of his starting material - a glass jar, tin and air - was equal to the mass of the material produced - a glass jar, "Tin calcium" and the rest of the air.
The term "atom" arrives from the language of Greek and means indivisible, because atoms were thought to be the tiny things present in the universe and could not be divided. But not familiar that atom comprises with three particles: proton, neutron and electron- even tiny particles like quarks.
