What percentage range of an adult's kilocalories is recommended as the maximum to be obtained from fat?

Biology

Darya [45]3 years ago
4 0
The percentage range of an adult's kilocalorie that is recommended as the maximum to be from fat is between 20-35% of kcal from fat. Fats and oils are part of a healthful diet, however the type of fat makes a difference to heart health and the total amount of fat consumed is important. Fat contains about 9 kilocalorie per gram. Fats are classified as saturated, monosaturated, or polysaturated based on the type of chemical bonds in their fatty acids. The recommended fat intake is between 20 to 30 percent of calories for adults, 30 to 35 percent of calories for children  2 to 3 years and 25 to 35 percent for adolescents 4 to 18 years of age.

Lh is released by the anterior pituitary gland to stimulate sertoli cells to produce sperm. (lo 13.2) true or false
harina [27]
This is false for a number of reasons. While LH (which stands for Leutinizing Hormone) is released by the anterior pituitary gland and can be present in both females and males, it play a more predominant role in females. Working closely with FSH (Follicle Stimulating Hormone) a surge in LH begins the process of ovulation and the development of the Corpeus Leuteum.

In Males it is used both for the production of sperm but to stimulate the production of testosterone.

What is the pH if 20 mL of pH = 2 solution is diluted to a final volume of 600 mL?
Mashutka [201]

Explanation:

Hydrogen atoms contain 1 proton and 1 electron while being devoid of neutrons. When they lose their electron they form an ion or H+, a particle carrying a unit of positive charge.  pH measures how basic or acidic a water-based solutions are, with a formula for pH is

pH = -log[H+].

...where pH is -base 10 log of the concentration of hydrogen ions within the solution.

Initial volume= 20 mL

Final volume= 600 mL

# of dilutions= \frac{600}{20} = 30

for a pH 2= [H+]= 10^{=2}

∴ [H+]=  \frac{10^{-2}}{30} = 3.333 * 10^{-4}

and pH is an antilog of [H+]= - log \frac{10^{-2}}{30} = 3.333 * 10^{-4}

∴pH = 3.47

An isolated system is best characterized as a system in which: Energy can freely enter and leave but matter cannot. Matter and e
alexandr1967 [171]

In physical science there are two types of "isolated systems"


1. Being a Physical System in which it is so far removed from other systems that it does not react with any of them.


2. Being a Thermodynamic System in which it is enclosed by rigid immovable walls of which neither mass nor energy can flow through.


I believe in this case although not stated that it would refer to a Thermodynamic System which would leave you with the only plausible answer as ENERGY AND MATTER CANNOT ENTER OR LEAVE.


None of the other answers make sense. Even if it were referring to Physical. Physical does not react with anything at all. An as you can see Thermodynamic does not allow for anything to pass through or leave.
