Most living things need oxygen to survive. You breathe in oxygen and it is carried to this organ. Here the red blood cells pick up the oxygen and carry the oxygen to all the body cells that need it. What is this organ?A) diaphragm
B) heart
C) lungs
D) trachea

Answers

Answer:

The correct answer would be the C) lungs.

Lungs are the pair of air-filled spongy organs.

They are mainly associated with the exchange of gases (carbon dioxide and oxygen) in the body.

The alveoli are the group of tiny air-sacs present in the lungs which form the site of gas exchange.

The oxygen from the alveolar site diffuses into the blood and carbon dioxide from the blood diffuses into the alveolar site.

The oxygen is then transported to all cells of the body with the help of circulatory system whereas carbon dioxide is removed out of the body as a part of exhaled air.
C) the lungs.
The air moves down the trachea and into the lungs where it is picked up by the blood

How can using a combination of policy tools be more efficient than using one exclusively?a.
Using a combination of policy tools assures compliance.
b.
Using a combination of policy tools allows for a wider range of coverage.
c.
Using a combination of policy tools prevents the use of mandatory policies.
d.
All of the above

Answers

Answer:

c.   Using a combination of policy tools prevents the use of mandatory policies.

Explanation:

Regulating and controlling behavior is crucial for authorities. Authorities employ a number of tools such as enactment, penalties, laws, taxes, and support in order to change behavior in the concern of the people. The rising amount of policy difficulties has produced a difficulty for governments to control action. Moreover, conventional tools and methods in executing policy may be insufficient and ineffectual in circumstances of our current situation.
The correct answer to the question above is (c.) using a combination of policy tools prevents the use of mandatory policies. Using a combination of policy tools can be much more efficient than using the one exclusively simply because it prevents the use of mandatory policies.

Vitamins are specific organic compounds that are required in the diet to aid in digestion of :__________a) proteins.
b) provide essential amino acids.
c) prevent deficiency diseases.
d) provide fiber

Answers

Answer:

c) prevent deficiency diseases.

Explanation:

Vitamins are essential and specific organic compounds that are required mainly in the diet to facilitate the digestion of protein, however, they are not categorized with amino acids and as such they can't provide essential amino acid.

Vitamins are categorized into fat soluble vitamins(A,D,E and K) and water soluble vitamins (B anc C). Vitamins provides several to hundred of roles, majorly they helps  to prevent deficiency diseases. Few of their roles are:

Vitamin A helps to prevent blindness. Food sources to obtain vitamin A include spinach, cod liver oil etc.

Vitamin D helps to maintain skeletal structure due to the calcium content embedded in Vitamin D. Therefore, lack of vitamin D can cause rickets.

Vitamin B-complexes e.g B-1 (thiamin) helps in synthesis of certain hormones,  B-2 (riboflavin) which asssists in breakdown of fats and energy production. It can be gotten from Milk, youghurt etc. Deficiency in these vitamin B-complexes can cause heart-related disease, skin disorders, anemia etc.

At the end of meiosis II, how does the DNA in each of the four new cells compare to the DNA from the original cell?

Answers

At the end of meiosis II, the DNA in each of the four new cells compared to the DNA from the original cell is half as much and genetically different from the original. Meiosis is a part of cell division that results in the reduction of chromosome number by half in daughter cells. So, all daughter cells will have as half as much the original cell have. Nonetheless, during meiosis, the exchange of genetic material between homologous chromosomes occur. So, all daughter cells are genetically different from the original cell.

Answer: C. Half as much and genetically different from the original.
