3. DIFFERENT genes are active at DIFFERENT time. True/False Provide an example of this in humans: Answer here..​

Answers

Answer 1

Answer:

Explanation:

1. True, all cells in one body do have the same genes. AN example is keratin or collagen. Collagen is produced in the skin, is you have brown hair it is expressed but if you have black hair it is repressed.

2. I believe this one is true I am not sure.  Every cell has a different duty but the same genetic instructions.  Different types of genes can be turned off and on by different cells.  The liver cells are different from the nerve cells but still have the same DNA in your body.

3. True! An example is when you are young you are growing but those genes stop when you are an adult and stop growing taller.

A farmer has grown strawberries successfully for years in field A. He recently expanded the crop into previously unused land in fields B and
C. The yield from field B is comparable to A, but the yield from field C is inexplicably low. As a microbiome expert, what might you predict
about the soil of fields A, B, and C?

Answers

Given what we know, we can confirm that the soil in field C most likely lacks the presence of microbes that help plants grow or has a higher presence of microbes that are harmful to plant growth.

What does it mean for a microbe to promote plant growth?

This would mean that the microbe in question has a symbiotic relationship with plants. Meaning that it promotes plant growth in exchange for nutrients from the plant, and both organisms will benefit, similar to microbes such as AM fungi.

Therefore, we can confirm that the soil in field C is likely to lack plant symbiotic microbes that are most likely found in fields A and B.

What are taste buds?

Taste buds are present in the tongue. They are responsible for the taste of whatever we eat. Taste buds are of different types. Like bitter, sweet, salt, and sour. They are different taste buds and are present in the different regions of the tongue.

The frontal and temporal lobe of the brain is responsible for the taste of food and other things. The frontal lobe is present in the frontal part of the brain, and the temporal lobe is on the side of the brain above the ears.

Different lobes of the brain are responsible for different works of the body.

A person starts to eat a hamburger. As she takes a bite and chews, an enzyme called salivary lipase helps to begin the process of fat digestion. Which of these is the BEST description of the role of enzymes in digestion?

Answers

Answer:

Role of enzymes in the human body

Explanation:

The chemical reactions that keep us alive - our metabolism - rely on the work that digestive enzymes do. They help to accelerate (catalyze) chemical reactions in the human body.

In some cases, they can cause a chemical reaction millions of times faster than they would without them.

Important functions of enzymes:

Digestive enzymes help the body break down larger complex molecules into smaller ones such as glucose, so it uses them as fuel.

Every cell in our body contains DNA. Each time the cell divides, this DNA must be copied. The process is called DNA replication . Enzymes help in this process by developing the DNA helix and copying the information.

Liver enzymes break down toxins in the body.

Enzymes are especially needed for respiration, digestion, muscle and nerve function, among other important roles.

C. Enzymes are proteins that speed up the process of chemcially breaking down food molcules.

11. Make a checklist for
a client to use to
determine normal and
abnormal behaviors of a
pet. Include & label
behaviors that require an
owner to seek veterinary
attention.

Answers

Veterinarians have a great opportunity to save pets’

lives by recognizing that behavioral medicine is as

important as any other field of veterinary medicine,

and can routinely be incorporated into each veterinary

visit. Because most veterinarians never received education in veterinary school about feline behavior, and do

not have the time and resources to study all the latest

research and develop behavior protocols, the panelists

have worked to develop a concise, updated and “user

friendly” document that can be easily implemented.

The guidelines include the following information:

• Emphasis is on prevention, from pre-adoption or the

first veterinary visit, through senior life. Preventing

behavior problems should be an important part of total

wellness care. A list of behavior questions intended for

inclusion in the medical history questions used at each

appointment is provided to aid in early detection and

intervention of behavior problems.

• An outline is provided for guidance regarding how to

create realistic expectations about living with a cat. This

will encourage cat owners to provide positive outlets to

allow normal behavior, but in ways that clients will consider acceptable.

• Several of the appendices can be used for both prevention and treatment and can be made into client

handouts; these will delegate client education to the

veterinary support team and be used to facilitate the

veterinarian’s role in client education.

• A developmental table specifying home and veterinary

care needed at different stages of life is included. This

can serve as an excellent poster or client information

handout to help clients understand their responsibilities for home and veterinary care.

• Detailed information on behavior and environmental

enrichment is included to help prevent many of the

most common behavior problems.

• Suggestions regarding prevention and treatment of

obesity, the most common consequence of domestication of cats, are provided.

• To help veterinarians better handle routine behavior

concerns (eg, inappropriate elimination) a rational first

approach to the problems seen day-to-day is included.

• Behavior counseling and treatment, including behavior

modification and environmental enrichment, are discussed in detail. For cats needing medical treatment,

important drug information including dosing and

tapering of medication is provided. Information on

where to refer if needed is also provided.

• Information is provided that will promote comprehensive, state-of-the-art, holistic care that incorporates

both the physical and psychological well-being of our

feline patients.

• These guidelines will help veterinarians raise client

awareness that they should turn to the veterinary profession for advice regarding behavior, just as they do

with any medical concerns.

Summarize the steps of glycolysis using the key terms ATP, ADP, NAD+, NADH, glucose, and pyruvate.

Answers

Explanation:

LOOK AT THE FLOW CHART

IT MIGHT HELP U OUT

In this question we summarize the steps of glycolysis which is a process that occurs through a series of 10 reactions divided into two steps using the key terms ATP, ADP, NAD+, NADH, glucose and pyruvate.

Steps of glycolysis

1st stage

This step, also known as the preparatory phase or investment phase, consists of five reactions:

1. Phosphorylation of the glucose molecule occurs, in which it receives phosphate from the ATP molecule, forming glucose 6-phosphate;

2. The glucose 6-phosphate molecule undergoes a rearrangement and forms fructose 6-phosphate;

3. Another ATP molecule supplies phosphate to the fructose 6-phosphate molecule, giving rise to fructose 1,6-diphosphate;

4. The fructose 1, 6-diphosphate molecule undergoes a rearrangement, with the opening of its benzene ring, giving rise to two molecules with three carbons each: glyceraldehyde 3-phosphate and dihydroaxethone phosphate;

5. The dihydroaxethone molecule undergoes a rearrangement giving rise to another glyceraldehyde 3-phosphate molecule.

It can be seen that at the end of this first phase, there was only energy expenditure, with the conversion of two ATP molecules into ADP.

→ 2nd stage

This stage, also known as the profit or energy compensation stage, involves energy gain and also consists of five stages, described below:

6. Two molecules of NAD+ (nicotinamide dinucleotide and adenine) are reduced to two molecules of NADH with electrons from the oxidation of glyceraldehyde 3-phosphate to 1,3-diphosphoglycerate;

7. Each molecule of 1,3 – diphosphoglycerate yields a phosphate to one molecule of ADP, thus giving rise to two molecules of ATP and two molecules of 3 – phosphoglycerate;

8. A rearrangement of 3 – phosphoglycerate molecules occurs, forming 2 – phosphoglycerate;

9. The 2 – phosphoglycerate molecules lose a H2O molecule, giving rise to phosphoenolpyruvate;

10. Phosphoenolpyruvate molecules provide a phosphate to an ADP molecule, yielding two ATP and two pyruvate molecules.

With this information, we summarize the steps of glycolysis which is a process that occurs through a series of 10 reactions divided into two steps using the key terms ATP, ADP, NAD+, NADH, glucose and pyruvate.
