Answer:
Cancer and Arthritis
Explanation:
Some causes of cancer include smoking, obesity, and lack of nutrition. Cancer is diagnosed using a biopsy. A biopsy is a procedure in which the doctor removes a sample of tissue. A pathologist looks at the tissue under a microscope and runs other tests to see if the tissue is cancer. Some treatments for cancer include Chemotherapy, surgery, Radiation therapy, and bone marrow transplant.
The most common cause of arthritis is usually if your family has a history of arhritis. It is usually diagnosed with an x-ray or a blood test. Treatment includes Painkillers, physical therapy, and exercise.

What is oviparous?Oviparous is the animals that lay eggs as their young ones and Most cockroaches are oviparous it means they lay eggs and their young ones grow in the eggs outside the mother's body. These nymphs will be feed and go through a series of the moultings over a period of one year as they develop into adults.
Genetic mutation, crossing over during meiosis, polypoidy is an example of a cause of natural variation to the mechanism of natural selection. Variation shown in many ways such as physical appearance, metabolism, reproduction, fertility behavior, learning and mental ability, such variation is called as natural variation.
Therefore, The description of life cycle of mosquito and cockroach is that the cockroach life cycle has been comprised of three developmental phases, the egg, nymph and the adult stage. Most cockroaches are oviparous it means they lay eggs and their young ones grow in the eggs outside the mother's body.

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

Question 3
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.
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.

1.Explain what makes a scientific experiment reliable. Be sure to include at least three reasons to support your answer.
2.During research, why is it important to use peer reviewed evidence when collecting background information during a scientific investigation?
Answer:
1:When a scientist repeats an experiment with a different group of people or a different batch of the same chemicals and get very similar results then those results are said to be reliable.Reliability is measured by a percentage if you get exactly the same results every
time then they are 100% reliable.
2.The peer reviewer determines whether the introduction provides sufficient background information on the research topic, and ensures that the research question and hypothesis are clearly identifiable.
