In an effort to identify the influence of genetic factors on both Type I diabetes and Type II diabetes, researchers calculated concordance rates for monozygotic twins. Concordance rates of 30–50% have been found for Type I diabetes and concordance rates of 80% for Type II. For both kinds of diabetes, dizygotic concordance rates were about 15%. What does this information suggest concerning the relative effect of genetic and environmental factors for each type of diabetes?a) Environmental factors have no role in the occurrence of either type of diabetes.b) Type II diabetes appears to be caused by a single, unidentified gene.c) Genetic influences exert a larger role in Type II diabetes than in Type I diabetes.d) Genetic factors have little or no role in the occurrence of Type I diabetes.e) Type II diabetes is primarily determined by non-genetic factors.

Answers

Answer 1

The correct answer is C) Genetic influences exert a larger role in Type II diabetes than in Type I diabetes.

Explanation:

Monozygotic or identical twins share the same genes; due to this, if twins have the same diseases or there are concordance rates, it can be concluded the disease or condition is influenced by genetics.

In the case of diabetes, the concordance rate for Type II diabetes was high (80%), which proves this type of diabetes is influenced to a large extend by genetics. Similarly, in Type I diabetes genetics seem to have an influence but this is not as strong as in Type II because the rates were lower (30-50%).

Moreover, the results of dizygotic twins (twins with different genes) show diabetes is influenced by genetics because in these twins the genetics are not the same, and therefore the concordance rate is low.

4. Found lining the digestive and respiratory tracts.
5. Makes up the pleura and pericardium.
6. Lines blood vessels and the heart.

Answers

Answer:

Some of these sentences both refer to the same term.

1. The epithelial membrane that lines the closed ventral cavities of the body.  - 5. Makes up the pleura and pericardium. This is called the serous membrane.

2. The epithelial membrane that lines body cavities open to the exterior membrane . - 4. Found lining the digestive and respiratory tracts.  These statements refer to the mucous membrane.

3. Consists of keratinized stratified squamous epithelium.  - cutaneous membrane.

6. Lines blood vessels and the heart. - endothelium.

Explanation:

All of these membranes are formed by epithelial tissue - one of the four basic tissues found in the human body, with important tasks that many times give the organs they're part of their main function.

The epithelium can vary in shape and size in order to adapt to the necessities of the organ. If the organ needs protection from abrasions, like the skin or the stomach, this tissue will have many layers and be called "stratified epithelium". On the other hand, an organ with the function to exchange substances, like the blood vessels or the alveoli, will have only one layer of epithelium, to ease the diffusion of gases and other molecules.

The other three basic tissues are: connective tissue, muscle tissue, and nervous tissue.

A neuron has a positive charge on the outer surface of the cell membrane due in part to the action of an active transport system called the ____________. This system moves ____________ out of the cell and ____________ into the cell. The inside of the cell membrane is negative, not only due to the active transport system but also because of ____________, which remain negative due to the intracellular pH and keep the inside of the cell membrane negative.

Answers

Answer:

Neurons, as with other excitable cells in the body, have two major physiological properties: irritability and conductivity. A neuron has a positive charge on the outer surface of the cell membrane due in part to the action of an active transport system called the sodium potassium pump. This system moves sodium (Na+) out of the cell and potassium (K+) into the cell. The inside of the cell membrane is negative, not only due to the active transport system but also because of intracellular proteins, which remain negative due to the intracellular pH and keep the inside of the cell membrane negative.

Explanation:

Neurons are cells with the capacity to transmit information between one another and also with other tissues in the body. This information is transmitted thanks to the release of substances called neurotransmitters, and this transmission is possible due to the electrical properties of the neurons.

For the neurons (and other excitable cells, such as cardiac muscle cells) to be capable of conducting the changes in their membranes' voltages, they need to have a resting membrane potential, which consists of a specific voltage that is given because of the electrical nature of both the inside and the outside of the cell. The inside of the cell is negatively charged, while the outside is positively charged - this is what generates the resting membrane potential. When the membrane voltage changes because the inside of the cell is becoming less negative, the neuron is being excited and - if this excitation reaches a threshold - an action potential will be fired. But how does the voltage changes? This happens because the distribution of ions in the intracellular and extracellular fluids is very dissimilar and when the sodium channels in the cell membrane are opened (because of an external stimulus), sodium enters the cell rapidly to balance out the difference in this ion concentration. The sudden influx of this positively-charged ion is what makes the inside of the neuron become less negative. This event is called depolarization of the membrane.

A Tomato Has A Proton Concentration Of 0.00006 M. How Would You Calculate The PH?

Answers

Answer:

Option b. is correct

Explanation:

If hydronium ion concentration [tex]H_3O^+[/tex] is given then pH is given by [tex]-log[H_3O^+][/tex]

The hydronium ion refers to the hydrogen ion in aqueous solution.

A Tomato has A Proton Concentration Of 0.00006 M

Here, 0.00006 is equal to 6 × [tex]10^{-5}[/tex]

So,

pH is given by - log [6 × [tex]10^{-5}[/tex]]

Option b. is correct

The pH of the tomato which has a proton concentration of 0.00006 M is given by –Log (6×10¯⁵)

The correct answer to the question is Option B. –Log (6×10¯⁵)

From the question given above, the following data were obtained:

proton concentration [H⁺] = 0.00006 M = 6×10¯⁵ M

pH =?

The pH of tomato can be obtained as follow:

pH = –Log [H⁺]

pH = –Log (6×10¯⁵)

Thus, the correct answer to the question is Option B. –Log (6×10¯⁵)

Some benefits of dietary fiber are build muscle and flexibility.
True or False

Answers

Answer:

true

Explanation:

dietary fiber build muscle and flexibility

Dietary fiber is one of the components of a nutrient and balanced diet. Dietary fiber in the diet can build muscle and flexibility. Thus, the statement is true.

What is dietary fiber?

Dietary fiber along with the functional fibers makes the total fiber that makes part of the diet and is considered to be nutritious. They are homopolysaccharides that are made of various similar monomers linked concurrently by the glycosidic linkage.

Dietary fiber is composed of various units of cellulose linked chemically by the beta (1 - 4) glycosidic linkage. They have been known as roughage which are plant parts that are undigestable. Though they cannot be absorbed, but they ensure a smooth digestive and excretory process.

The presence of dietary fiber in the diet increases flexibility and muscle mass by decreasing body fat and is found in beans, broccoli, avocados, berries, apples, etc. It eliminates fats and other wastes from the body by promoting regular bowel movements.

Therefore, the statement is true.
