Which statement describes how chemical formulas, such as H2O, represent compounds? They show the types of molecules that make up an atom. They show the elements that make up a compound. They show the three-dimensional shape of a molecule. They show the types of bonds that exist between elements.

Answers

Answer:

They show the elements that make up a compound

Explanation:

Compound consist of molecules that are identical, this molecules are made up of atoms of two or more elements.

An element is identified based on the atomic property of the element.

Water as a compound is composed of 2 Hydrogen atom to 1 oxygen atom and the molecule is H2O.

Water is composed of molecules hence, they are called molecular compound.

Refrigeration _______ are the agents that act as carriers of a pathogen and spread diseases. A. Vectors B. Microbes C. Parasites D. DNA

Answers

Answer:

Mold grows best in warm, humid environments. So, I think B is the correct answer. Answers C and D would actually encourage the growth of mold.

I know that B (Tuberculosis) is spread by bacteria.

Pasteurization is the process where milk is heated up to kill certain pathogens.

Finally, vectors are the agents that carry pathogens from one person to another and spread disease.

Most students have trouble with understand that HCl and Bile are not enzymes. They do allow for structural changes of the substrate, but they do not change the chemical breakdown of the substrate (breaking bonds. Describe your experience: 1. How comfortable do you feel about the statement that was just made? 2. What is a catalyst? Do you think that HCl and Bile are catalysts? Explain. 3. Using your own example, make an analogy explaining, to an 8-year-old, the concept of how a chemical will cause mechanical breakdown of a substance but not a chemical breakdown.

Answers

Most students have trouble with understand that HCl and Bile are not enzymes. They do allow for structural changes of the substrate, but they do not change chemically breakdown the substate (breaking bonds)

Bile salt is  a fat emulsifier.It has an hydrophobic end  which points towards lipids and hydrophilic ends towards water.With this arrangement, the structure of fatty acid is modified in such a way that  the lipid is well distributed and scattered in  water.However, the chemical bonds in the lipids are not affected by the bile salts, because, bile did not  breakdown the chemical bonds in lipids to form new compound, its only changes  the food physical structure for easy digestion.

Describe your experience:

How comfortable do you feel about the statement that was just made?

What is a catalyst? Do you think that HCl and Bile are catalysts? Explain.

Using your own example, make an analogy explaining, to an 8-year-old, the concept of how a chemical will cause mechanical breakdown of a substance but not a chemical breakdown

Answer:

1.The statement means that,HCL and bile, which change the pH nature of the digesting food, and emulsify  the digesting food respectively, only allow for structural changes in these  food materials,but do not break or make new bonds between the components of the food substances.Therefore they  do  not formed new substances, but rather modified the  food substances, no chemical reaction occurs  but  their effects only aids  the process of digestion.

When a substances increases or speed up the rate of organic chemical reactions, but  do not undergo any permanent changes in it chemical structure, in the course of catalysis, the substance is called a catalyst.

During digestion, HCL activates precursor pepsinogen to enzyme pepsin , which aids protein digestion  in the stomach. HCL is not a catalyst,But acts  to aid the action of an enzyme , by  activating its precursor, for digestion to take place,The acid does not form a new compound.

Bile is an emulsifier , which aids the digestion of lipids  by forming to tiny globules for easy digestion. It does not form a new product, but rather modified the existing product for easy digestion.

(Check all that apply)
More myoglobin content of muscle
Greater mitochondrial power
Greater activities of the enzymes of the phosphagen system
More CP and ATP in muscle

Answers

Answer: Greater mitochondrial power

Greater activities of the enzymes of the phosphagen system

More CP and ATP in muscle

Explanation:

During high intensity exercises the large amount of muscle energy is required. This creates a high demand of ATP. The phosphagen system is the quickest method to resynthesize ATP. The creatine phosphate in the absence of oxygen provides phosphate to produce ATP. This provides greater mitochondrial power, in the rest the CP and ATP remain stored in the muscles. The enzymatic activity enhances with the phosphagen system.

Could someone help me match the types of resources with their descriptions ?

Answers

Answer:

They can be reproduced on a human time scale- Renewable resources

They take millions of years to form- Nonrenewable resources

They are produced naturally- both Renewable and Nonrenewable resources

They are extracted by mining- Nonrenewable resources

Their use as energy source is increasing because they reduce pollution- Renewable resources

Explanation:

1. Renewable resources are a type of natural resources that are replenished or reproduced by natural processes on a human time scale. Hence, they are inexhaustible as opposed to the Nonrenewable resources.

2. Nonrenewable resources are those resources that gets used up quickly than they can be replenished. Hence, they are exhaustible. These resources takes millions of years to form, and will take more to be replenished.

3. Both the renewable and Nonrenewable resources are found naturally i.e. they are exploited in their natural state, with no man forming them.

4. The Nonrenewable resources like crude oil, natural gas, coal etc. are found embedded in the Earth crust either in solid, liquid or gaseous form and are extracted by humans via MINING.

5. Renewable resources such as solar, wind, etc are increasingly used as sources of energy because of their eco-friendly characteristics. This means that they contribute less to emission of pollutants, that lead to global pollution. Hence, the reason renewable source of energy are called "Green or Clean" sources of energy.

what features of ionizing radiation make it a good choice for killing microbes in packaged materials?

A.ionizing radiation is able to penetrate the packaging materials

B.ionizing radiation is safe for killing microbes on living surfaces (such as human tissues)

C.ionizing radiation kills endospores

D.ionizing radiation does not require special instruments or equipment

Answers

Answer:

Normally sterilizing food using radiation does not induce radioactivity but sometimes it may change the taste, texture of the food and it may also destroy the nutrients. radiation is used to kill the harmful bacteria and to increase the shelf life. when the radiation is very energetic it alters the food structure but it does not make it radioactive. To become radioactive one has to make a nucleus unstable. ionizing radiation normally cannot do this. FDA has established maximum energy levels for radiation to prevent the treated foods from becoming radioactive. The energy levels of the rays are too low to induce radioactivity in the food. So there is no harm in consuming treated foods.
