What organism? If its plants, they give oxygen during the day and carbon dioxide in the night. While animals give carbon dioxide but take oxygen from the air. These carbon dioxide gas and oxygen gas go to the atmosphere and affect the carbon cycle and oxygen cycle.
Here is the cycle if you want to know more
Plants (give out oxygen) -> Animals (Use oxygen) + (given our carbon dioxide) -> plants (take oxygen)
and so on
I believe the answer is A) Foot
Answer:
The organ above is responsible for filtering wastes from the digestion of proteins and cleaning the blood of excess salts. It is found in the lower back. It is the <u>kidney </u> and is part of the <u>excretory</u> system.
Explanation:
Kidneys are a pair of a bean-shaped organ which are located in the back abdominal area, under the rib cage. The major function of kidneys is to filter waste from the blood. The waste materials from the food we consume is filtered by the kidneys. Other functions of the kidney include maintaining the fluid balance of the body.
The kidney is one of the major organ of the excretory system along with the ureters and urinary bladder.
Answer:
A diet combining legumes and cereals will have a good balance of essential amino acids
Explanation:
Cereals are grains that are rich in vitamins, carbohydrates, protein and other essential nutrients, they include wheat, rice, sorghum etc. Legumes include a wide range of seeds, fruits, nuts, vegetables that are rich in proteins, carbohydrates and other nutrients, examples include peas, beans, lentils etc.
Cereals and legumes are referred to as staple foods, they are usually used to complement each other because combining them will result in a good balance of essential amino acids. In cereals, lysine is a limiting amino acid but is usually in high amounts in legumes. However, in legumes cysteine, trypthophan and methionine are the limiting amino acids but are found in cereals. Therefore, this makes legumes and cereals complementary in the diet as it significantly increases the protein quality of the diet.
I would believe the correct responses would be option 1,2,4.
