What is the purpose of greenhouse gases?
Answer:
Image result for what is the purpose of greenhouse gases
Greenhouse gases are certain molecules in the air that have the ability to trap heat in the Earth's atmosphere. Some greenhouse gases, like carbon dioxide (CO2) and methane (CH4), occur naturally and play an important role in Earth's climate. If they didn't exist, the planet would be a much colder place.

Describe the stage of the cell cycle that takes place before mitosis.
The _____ stage occurs before mitosis. In this stage extra sub-______ structures are produced.
The interphase stage occurs before mitosis. In this stage, extra sub-phases like G1, S, and G2 are produced various proteins necessary for divisions.
What do you mean by Cell cycle?The Cell cycle may be defined as the process a cell goes through each time it divides.
Interphase is the initial stage of any cell cycle which is the interval between the end of one mitotic or meiotic division and the beginning of another. It is the longest phase of the cell cycle as compared to the mitotic phase.
Therefore, the interphase stage occurs before mitosis. In this stage, extra sub-phases like G1, S, and G2 are produced various proteins necessary for divisions.

How does diagnosis explain why 1 ml of liquid from her small intestine digested protein slowly but 1 mg of her pure protease protein normally?
Answer:
Due to the absence of proteolytic enzymes.
Explanation:
The study diagnosis that small intestine digested protein slowly due to the absence or decrease quantity of proteolytic enzymes in the small intestine. Proteolytic enzymes are responsible to speed up the digestion process and after digestion amino acid is produced which is directly injected into the blood that is used by the body for the formation of muscles.

Answer:
F. Is fatty acid molecule.
Explanation:
It's unsaturated fatty acid.
Fatty acid consists of a straight chain of an even number of carbon atoms, with hydrogen atoms along the length of the chain and at one end of the chain and a carboxyl group (―COOH) at the other end.
It is that carboxyl group that makes it an acid (carboxylic acid).
Hydroponics is defined as the practice of growing plants without soil used to provide support or nutrients or ‘Soilless Farming'. How is ‘Hydroponics' an effective method of farming in arid and dry zones other Earth?
Answer:
Hydroponics solves the problem of unavailability of water in those arid and dry regions
Explanation:
As rightly stated in the question, hydroponics is a practice that involves the culturing of plants without the need for soil. Hydroponics procedure make use of a moisture-containing solution filled with nutrients.
This procedure of hydroponics, however, comes with some disadvantages but one major effectiveness it has in arid or dry regions is that it SOLVES THE PROBLEM OF WATER UNAVAILABILITY. When it comes to farming practice using soil, constant water supply is an unnegotiable criterion because water is needed for the growth of plants in the soil.
However, in arid regions, which are usually very dry due to lack of rainfall, the practice of hydroponics can substitute for soil farming in order not to cause food scarcity.

Volleyball season is right around the corner and I think I need to make sure I am healthy and I want to lose some weight. I keep seeing these commercials for Special K cereal and if you eat it for 2 weeks, you will lose 10 pounds. I want to test this idea and see if it actually works. I plan on eating whatever I want for the next two weeks and am going to track my weight every morning. Then I will eat nothing but Special K cereal, milk and water for two weeks and track my weight in the morning. What do you think my hypothesis should be? What will my variables be? Hypothesis: Independent variable: Dependent Variable:
Answer:
Hypothesis: If you eat Special K cereal for 2 weeks, you will lose 10 pounds.
Independent variable: Special K cereal.
Dependent Variable: Weight lose.
Explanation:
Hypothesis: The term "hypothesis" is determined as a testable and a precise statement of what a specific researcher or experimenter predicts would be considers as the outcome of a particular study.
Independent variable: In research, the term "independent variable" is determined as a variable that is being re-organized in an experiment or research in order to see its impact on the dependent variable. Independent variable influences the dependent variable directly.
Dependent variable: The term "dependent variable" is determined as a variable that is being measured or tested in an experiment or research by the experimenter or researcher and is directly influenced by the independent variable.
