<h2>Answer is option "A"</h2>
Explanation:
- Skeletal muscle tissue structures skeletal muscles, which join to bones or skin and control headway and any development that can be deliberately controlled. Since it very well may be constrained by thought, skeletal muscle is additionally called willful muscle.
- Skeletal muscle likewise has numerous cores present in a solitary cell. Smooth muscle has no striations, isn't under deliberate control, has just a single core for each phone, is decreased at the two finishes, and is called automatic muscle. Cardiovascular muscle tissue is just found in the heart, and cardiovascular compressions siphon blood all through the body and keep up circulatory strain. It has one core for every cell, is spread, and is recognized by the nearness of intercalated plates.
- Hence, the right answer is option a "All of the listed statements are true"
Hormones glucagon and insulin are produced in the alpha and beta cells respectively in the Islet of Langerhan in the pancreas. They are involved in the negative feedback system of blood glucose regulation in homeostasis.
GLUCAGON: when there is a low blood glucose concentration, the pancreas detect this and alpha cells produce and release glucagon. Glucagon causes the cells of the body to absorb less glucose from the blood. It also inhibits the process of converting glucose into glycogen (glycogenesis) and cause gluconeogenesis (process of converting amino acids/proteins and lipids/fats into glucose) and glycogenolysis (conversion of glycogen to glucose). Finally, glucagon decreases the rate of respiration so less glucose is required.
INSULIN: when blood glucose is high, insulin is released. Insulin binds with cell surface receptors of cells and activates the enzymes attached to the receptor. The enzymes cause a conformational change in the structural proteins that surround glucose transport protein containing vesicles, causing them to move out of the way so the vesicles migrate up to the cell membrane and glucose transport proteins can fuse with it. Thus, more glucose can be taken in by cells. Insulin also cause glycogenesis (converting glucose into glycogen) and inhibits gluconeogenesis and glycogenolysis.
Basically insulin decreases blood glucose concentration (eg. after eating) and glucagon increases it (eg. skipping breakfast in the morning)
The <span>Crohn’s disease can be an example of a disease associated with the digestive system.
The </span>Crohn’s disease is a chronic inflammation<span> of the </span><span>gastrointestinal tract. Although it can be developed in any part of the gastrointestinal tract it is mostly aggressive ate the end of the small intestine to the passage to large intestine. It affects equally men and women and it starts usually between the ages of 15-35 years of age. It may appear because of genetic factors, environment, and simply an overactive inflammatory system.
It usually presents abdominal pain, rectal bleeding, frequent diarrhea, loss of appetite, weight-loss, and fatigue.
It is usually tested by blood tests to identify eventual </span>deficiencies of vitamins or minerals, and other indicators of anemia or inflammation. Also fecal blood tests to identify if the problem could be a result of some kind of infection rather then Crohn's disease. Other tests may include X-rays, CT scans,or MRIs, leukocyte scintigraphy, e<span>ndoscopy, and colonoscopy.</span>
Answer:
dioxide and water.
Explanation:
The carbon comes from carbon dioxide which is used during photosynthesis.
During the process of photosynthesis, most plants get the sun's energy into chemical energy which is also captured within the bonds of carbon molecules built from atmospheric carbon dioxide and water.
