Answers

Answer:

P

Explanation:

Phospholipod is type of bilayer

Cells have phospholipid type of bi-layer that is not soluble in water.

What is cells ?The cells are basic structural unit of living organism.The cells have mainly three parts: cell membrane, the nucleus and cytoplasm.The cells are responsible for the all process of life

Why phospholipid is not solunle in water?The lipid containig a phosphate group in its molecule is called phospholipid.The cell membrane is made of phospholipid which is not soluble in water.The phospholipids has hydrophilic head contains phosphate group and two hydrophobic tails which drive from fatty acids and joined by alcohol.This fatty acid is made of ten or more carbon atoms and having low density . So, it float on the surface of the water when mixed with water.

The new Hazard Communication Standards provide teachers and students the right to __________ chemical hazards.

Answers

The new Hazard Communication Standards provide teachers and students the right to manipulate chemical hazards.

Chemical hazards are non-biological substances that can cause damage to health. These are used in different enterprises, companies, school, universities and laboratories for different purposes such as cleaning, disinfection, scientific experiments, among others. When handling them, employees are exposed to them and are vulnerable to harm from these chemicals.  

There are many types of hazardous chemicals to be wary of, such as:

Carcinogens NeurotoxinsAcids Systemic toxins Asmogens Silica dust Lead

In the workplace, exposure to these substances represents a real occupational hazard and there must be regulations to ensure that they are safe to handle.

The Occupational Safety and Health Administration (OSHA) is the agency of the U.S. Department of Labor which determined the Hazard Communication Standards. This is a document with the necessary information to study the hazards of the chemical substances used by different employees in the companies, so that they are aware of the dangers of these substances. These employees have the right to know exactly what compounds they handle and the risks involved in their use as well as the precautions and care to be taken.

Therefore, by having these safety standards in place in schools and universities, teachers and students have the possibility and the right to handle chemical hazards safely to be able to conduct the class normally and learn what is necessary.

Some globular proteins are water soluble, while all fibrous/membrane proteins are water insoluble.
Which of the following statements BEST explains the reason for these differences?
A
Fibrous proteins have a large number of hydrogen bonds between the amino acids in the polypeptide chains that stabilize their structures, preventing solubility in water. The globular proteins that are water-soluble do not have as many hydrogen bonds between the amino acids in their peptide chains, allowing water solubility.
B
Fibrous proteins are configured in a way that exposes the polar side chains of the amino acids on the surface of the protein, preventing solubility in water. The globular proteins that are water soluble have nonpolar side chains on the surface of the protein, allowing water solubility.
C
Some globular proteins are configured in a way that exposes the polar groups of the amino acids on the surface of the protein, allowing water solubility. Fibrous proteins have nonpolar side chains on the surface of the protein, preventing water solubility.
D
Some globular proteins are composed of more than one polypeptide chain that weakly interacts with one another, allowing water solubility. Fibrous proteins are composed of only one polypeptide chain that tightly folds, preventing water solubility.

Answers

Globular proteins are spherical proteins which are water soluble and forms colloid in water.

The best statement which will explain the reason for difference in globular protein and fibrous proteins is statement C.

C. Some globular proteins are configured in a way that exposes the polar groups of the amino acids in the surface of the protein, allowing water solubility.

Fibrous proteins have non polar side chains on the surface of the proteins, preventing water solubility.

Globular proteins are water soluble. Fibrous proteins are not soluble in water.

Amino acids chain prevents folding up so that the chain is not broken and it remains in elongated form. The correct answer is C.
