A normal protein has 300 or more amino acids, and each protein has a different ratio and order of amino acids.
What is meant by protein?Large biomolecules and macromolecules known as proteins are made up of one or more extended chains of amino acid residues.
(PROH-teen) a structure composed of amino acids. The body need proteins to function properly. They serve as the building blocks for several bodily components, including the skin, hair, and enzymes, cytokines, and antibodies.
Numerous distinct amino acids are bonded together to form proteins. These twenty distinct amino acid building blocks are widely distributed in both plants and animals. A normal protein has 300 or more amino acids, and each protein has a different ratio and order of amino acids.
Therefore, the correct answer is option b) 20 grams.

It was observed that the particles of an unknown substance slide past one another. What is the state of matter of the substance? (1 point)
Solid
Liquid
Gas
Plasma
The liquid is the state of matter of the substance. Hence, option B is correct.
What is a state of matter?A “state of matter” is a way to describe the behaviour of atoms and molecules in a substance.
In a liquid state of matter, particles are less tightly packed as compared to solids. Liquids take the shape of the container in which they are kept. Liquids are difficult to compress as particles have less space between them to move. Liquids have fixed volume but no fixed shape.
Hence, option B is correct.

State three reasons why an airborne pollutant might be deposited close to its source
Answer:
No wind
Rain
I only came up with 2 I couldnt think of a third one
If an airborne pollutant is brought to the ground by rain or snow, it will be deposited closer to its source. This is due to the fact that the chemicals must be discharged nearby the source or captured in a cloud that would then transfer them.
What are pollutants?Pollutants are substances which causes pollution to the atmosphere or hydrosphere. There are many types of airborne pollutants such as gaseous products from burning of fossil fuels.
Oxides of nitrogen and sulfur and some hydrocarbons are the main airborne pollutants. They can be easily condensed because of the atmospheric humidity.
The deposition of these pollutants also depends on the wind, temperature and diffusion rate of these gases. If the diffusion rate is less for the gas and the temperature is lower, they will deposit at the sources.

As the amount of salt in water increases, the___________ of the water increases.
1. temperature
2. humidity
3. density
4. size
Answer:
3
Explanation:
As the amount of salt in water increases, the density of the salt water increases. The more the particles of the in water being added to the total mass and thus increases the density.
What is density ?Density of a substance is the measure of its mass by volume. It describes how closely packed its particles are. The density of a substance depends on the bond type, pressure and temperature.
The density of pure water is 1 g/ml. However, when salt is added to water it becomes denser since the mass of the solution changes from that of water.
Hence, more the salinity of the salt solution, more denser it is. Because, amount of salt is contributing to the total mass. Therefore, As the amount of salt in water increases, the density of the salt water increases.
