Sunlight exposure has stronger effet on skin cancer risk in fairskinned humans than in individuals with darker skin. This is an example of A) pleiotropy B) epistasis. C) genotype-by-environment interaction. D) differences in the norm of reaction. E) All of these choices are correct

Answers

Answer 1
Answer:

Answer:

The correct answer is  C) genotype-by-environment interaction.

Explanation:

Gene-environment interaction shows that how to different genotypes respond differently to the environmental variation. It tells us about how genetic and environmental factors are involved in influencing a disease in humans.

According to gene-environment interaction, every genotype responds differently to the environmental variations for example humans with genes that favor fair skin color have more chances to get skin cancer than the people who have the gene that code for darker skin color.

So by this example, we can say that different genotypes interact differently with the environment. So the right answer is C.

Explanation: 1. Blood pressure is the pressure of circulating blood on the walls of blood vessels. Most of this pressure is due to work done by the heart by pumping blood through the circulatory system. Used without further specification, "blood pressure" usually refers to the pressure in large arteries of the systemic circulation.

2. The arteries (red) carry oxygen and nutrients away from your heart, to your body's tissues. The veins (blue) take oxygen-poor blood back to the heart. Arteries begin with the aorta, the large artery leaving the heart.

Net hydrostatic pressure (NHP) for filtration and reabsorption is expressed by: a. CHP-IHP
b. CHP+IHP
c. IHP-CHP

Answers

Answer:

The answer is CHP+IHP.

Explanation:

Capillary hydrostatic pressure (CHP) works toward interstitial fluid and  interstitial hydrostatic pressure (IHP) works toward capillary. Net filtration pressure for the filtration and reabsorption is obtained from the resultant force between CHP and IHP

Mathematically it is the sum of CHP and IHP. For filtration net hydrostatic pressure value is positive( i.e CHP+IHP = positive value), but for reabsorption net hydrostatic pressure is negative( CHP+IHP =negative value).

So the answer is CHP+IHP.

Muscle that raises ribs in forceful inhalation or pulls scapula forward and downward.

Answers

Answer:

Muscle that raises ribs in forceful inhalation or pulls scapula forward and downward is  pectoralis minor.

Explanation:

pectoralis minor -

The location of pectoralis minor is in the upper part of the chest ,  under the pectoralis major ,

And the combination of both pectoralis minor and pectoralis major forms the wall of the axilla.

pectoralis minor is a triangular , thin muscle.

The main function of pectoralis minor is stabilization , abduction , depression and downward rotation of the scapula.

In case of the immobilization of ribs , pectoralis minor brings the sacpula forward and when lifts up the rib cage when the scapula is fixed.

Which of the following statements is NOT true of saturated fats and added sugars?a.Neither cheese nor pizza contribute significantly to solid fat intake.b.Increasing saturated fats and added sugars in foods will reduce nutrient density.c.Foods high in saturated fats and added sugars have a high energy density.d.Sodas, energy drinks, sports drinks, and desserts are significant sources of added sugars.

Answers

Answer:

Neither cheese nor pizza contribute significantly to solid fat intake.

Explanation:

The four important components of the living organisms are  carbohydrates, proteins, lipids and nucleic acids. These component provide structural as well as functional role in the living organisms.

The fat must be obtained from the diet as fats are the storage source of energy. The fat deficiency can cause several diseases in human but excess fat in the body can cause overweight and obesity. The fast food like cheese, pizza and burger contribute to the solid intake of fat in the body.

Thus, the correct answer is option (a).

Answers

Answer:

The correct option is D. Nitroglycerol

Explanation:

The drugs which are used to suppress the abnormal rhythms of the heart are called anti-arrhythmic agents or cardiac dysrhythmia medications.

Many anti-arrhythmic agents have multiple modes of action. Some examples of the anti-arrhythmia agents are- Amiodarone, Digoxin and Lidocaine.

Therefore, Nitroglycerol is not an anti-arrhythmic agent. It is used for the treatment of heart attack, angina, high blood pressure, coronary artery spasms.

The origin of the _______________ is on the iliac crest and inguinal ligament.

Answers

Answer:

The origin of the transverse abdominal muscle is on the iliac crest and the inguinal ligament.

Explanation:

The transverse abdominal muscle, also known as transversus abdominis muscle, originates from the inguinal ligament, the Iliac crest, thoracolumbar fascia and the costal cartilages 7-12 and inserts into the Xiphoid process,  pubic crest, linea alba and the pecten pubis. It is the innermost flat muscle layer of the anterior and the lateral abdominal wall.

Therefore, the transverse abdominal muscle arises from the iliac crest and inguinal ligament.
