When performing a wall sit or a squat (repeated motion with the squat), what major muscle groups are being used

Biology
1 answer:
Katen [24]3 years ago
8 0

The major muscles involved while performing a wall sit or squat are the quadriceps muscles.

Explanation:

Exercises like wall sit or squat are an isometric exercises which works the entire group of lower body muscles.

Isometric exercises are endurance building exercises which improves the muscle endurance by holding it in a position for longer time. These exercises does not involve any big bodily movements but works by tensing the muscles.

Both these exercises primarily involve the front thigh muscles or the quadriceps. Squats and wall sits help to tone and shape the quads and other muscles involved. The angle of the body should be maintained at right angle to reduce the pressure on these muscles.

Other muscles which are involved in these exercises are the hamstrings, core, lower back muscles etc.

The fourth reaction involving Gly-4 ( aldolase) is an especially important reaction in glycolysis. Why is this?
lapo4ka [179]
Glycolysis is the metabolic process of converting glucose into a pyruvate. It serves as a foundation for the two cellular respiration namely the aerobic and anaerobic respiration. It has four reactions namely, hexokinase, glucose-6 pshospahate isomerase, phosphofructokinase (PFK) and aldolase.

Aldolase or Glycolysis reaction 4 is significant because it splits the fructose1,6 biphosphonate into glyceraldehyde-3-phosphate (GAP) and dihydroxyacetone phosphate (DHAP).

Damaged tissue releases chemicals that activate platelets and stimulate the formation of blood clots. Which of the following pre
Zielflug [23.3K]

Hello! I figured your question was lacking its options so I went online to find them and here they are:

A. Activated platelets release chemicals that  inhibit blood clot formation.

B. Activated platelets release signaling  molecules that inhibit cell division in  damaged tissue.

C. Activated platelets constrict the blood  vessels, stopping blood flow.

D. Activated platelets release chemicals that  activate more platelets.

Answer:

The correct answer is: D) Activated platelets release chemicals that  activate more platelets.

Explanation:

<u>Positive feedback</u><u> is a mechanism in which a stimulus triggers an intensification of this same stimulus.</u>

When a tissue is damaged, the platelets participate in a process called platelet adhesion that consists of contacting and sticking to the collagen fibers of the connective tissue under the damaged endothelial cells. This platelet adhesion <u>activates</u> the platelets and makes them grow projections to contact and interact with one another, while releasing substances to activate other nearby platelets. The accumulation and the attachment of large numbers of platelets ultimately form a <u>platelet plug</u>.

Drag the tiles to the correct boxes to complete the pairs.
Nonamiya [84]

Ans.

Platelets are a type of blood cells, responsible for blood clotting. These cells prevent excessive blood loss from wound as they form plug or clot at the site of injury to repair the damage.  Thus, the option). platelets is correctly matched with 'clotting blood.'

White blood cells or WBCs are components of immune system that protect the body from harmful foreign molecules, such as bacteria, fungi, and viruses and harmful body cells, such as tumor cells.  Thus, the option). white blood cells is correctly matched with 'fighting bacteria.'

Red blood cells or RBCs are blood cells that transport oxygen, carbon dioxide, and nutrients to the different part of the body. These cells are made up of hemoglobin and protein. Thus, the option). red blood cells is correctly matched with 'clotting blood.'

Plasma is the non-cellular, colorless, fluid portion of blood, composed of proteins, vitamins, antibodies, amino acids, and other micromolecules. It is responsible for viscous nature of blood. Thus, the option). plasma is correctly matched with 'providing viscosity to the blood.'

Solar cells harness the sun's energy and convert it into electricity. However, the cost of this clean energy is much higher than
Dafna11 [192]

Answer:<u> Option D </u>

Solar panels contain a very expensive element, i.e. silicon. This element is able to convert the solar energy into electric energy. The cost of the solar panel gets expensive because of this rare element. It is found in limited areas of the world. That’s why option D is correct. Coal is not used in solar panel, so option B is incorrect. Neither is wind energy, so option A is also incorrect. Water is also not used for exploiting solar energy, which makes option C a wrong answer.
