What chemical bond is responsible for the paring of the nitrogenous bases in a DNA molecule?

1. Explain the relationship between surface area and absorption. Use an example of an organ to support your explanation.

san4es73 [151]

Small intestine is the organ which has villi contains large surface area for absorption.

The small intestine has a tendency to be the region of finest absorption ability for most drugs due to its large surface region, the presence of both energetic and passive absorption mechanisms, and close to neutral pH.

But, about ninety five percent of nutrient molecules are absorbed inside the small intestine. The absorption of most people of these molecules takes area in the second a part of the small intestine, called the jejunum. Absorption refers to the movement of nutrients, water and electrolytes from the lumen of the small gut into the mobile, then into the blood.

The small intestine is right for absorption since it has a huge inner surface location. That is shaped due to the plicae circulates which undertaking many tiny finger-like systems of tissue called villi. The character epithelial cells also have finger-like projections, which can be referred to as referred to as microvilli.

Sherry has addison's disease so her ability to produce cortisol is reduced. how does her hypothalamus respond?

Readme [11.4K]

When an individual's cortisol levels are low, such as in the case of people with Addison's disease, the hypothalamus region of the brain releases corticotrophin-releasing hormones. This causes the pituitary gland to also secrete another hormone called, adenocortocotropic hormone into the bloodstream. When the adrenal glands detect these hormones, they secrete cortisol, causing blood levels of cortisol to rise.

Bill is trying to plan a meal to meet specific nutritional goals. He wants to prepare a meal containing rice, tofu, and peanuts

Anastasy [175]

Answer:

Bill needs to eat 5 Cups of rise, 1 cup of tofu and 4 cups of peanuts

Explanation:

Its simple calculations:

As Bill requirement is 350 grams of carbohydrates, 311 grams of Fats and 168 gram of proteins.

Each cup of rice provides 42 grams of carbohydrates, 0 grams of fat, and 1 gram of protein.

Each cup of tofu provides 4 grams of carbohydrates, 11 grams of fat, and 23 grams of protein.

Each cup of peanuts provides 34 grams of carbohydrates, 75 grams of fat, and 35 grams of protein.

If he eats 5 cups of rise than he gets 42 × 5 = 210 grams of carbohydrates. similarly he gets 0 × 5 = 0 grams of fats and 1 × 5 = 5 grams of proteins.

If he eats 1 cup of tofu than he gets 4 × 1 = 4 grams of carbohydrates. similarly he gets 11 × 1 = 11 grams of fats and 23 × 1 = 23 grams of proteins.

and If he eats 4 cups of peanuts than he gets 34 × 4 = 136 grams of carbohydrates. Similarly he gets 75 × 4 = 300 grams of fats and 35 × 4 = 140 grams of proteins.

GRAND TOTAL BECOMES

CARBOHYDRATES: 210+4+136=350 grams

FATS: 0+11+300= 311 grams

PROTEINS:5+23+140=168 grams
