Anon25 [30]

The option that best illustrates the similarity and difference in the elemental makeup of these molecules is that carbohydrates and lipids both contain carbon, hydrogen, and oxygen atoms, while the proteins contain nitrogen in addition to those three elements. That is option B.

Carbohydrates are macromolecule found is food substances that plays a vital role of energy supply to the body.

It is made up of chemical elements such as carbon,hydrogen and oxygen in the ratio of 1:2:1.

Lipid is another macromolecule found in food which is an energy reserve for the body.

Lipids are made up of elements seen in carbohydrates such as carbon, hydrogen and oxygen but contain many more hydrogen atoms than oxygen atoms.

Proteins are another type of macromolecule found in food which helps in body building and repair of worn out tissues.

Proteins are made up of elements seen in carbohydrates and lipids with the addition of nitrogen atom.

Therefore, carbohydrates and lipids both contain carbon, hydrogen, and oxygen atoms, while the proteins contain nitrogen in addition to those three elements.

Phytoplankton form the base of food webs, but are only present in the upper few hundred meters of the ocean. A number of factors
Ksenya-84 [330]

Answer:

The correct answer is d. Oxygen

Explanation:

Phytoplanktons are responsible for the fixation of approximately half of the global carbon therefore seawater has high CO2 concentration which is required by phytoplanktons to make their food.  

They are the primary producers of oceans and they are responsible to support the food chain of oceans. Factors that can limit their growth are mainly sunlight and nutrients like phosphorus, nitrogen, etc.

As phytoplanktons are photosynthetic they release oxygen itself as a byproduct therefore oxygen is not a limiting factor to phytoplanktons. So the right answer is d.

Ms. Hendren has decided that she would like to grow some tomatoes and wants to know how much light will cause the plant to grow
yan [13]

Answer:

The correct answer is -

Independent variable - the amount (time period) of light given to pots.

Dependent variable - size of tomatoes

Control variable - dark or absence of light

Control group - pot placed in the darkroom.

Explanation:

The independent variable is the variable that is changed or manipulated in particular research or study to see the effect of that variable on dependent variable. In this case, the amount of light each pot gets is the independent variable.

The dependent variable is the variable that depends on the change in the independent variable. The size of tomatoes is the dependent variable here.

The control variable is the variable that remains in standard condition or condition which can be used to compare with the effect of the independent variable. The absence of light on one of the tomato pot is the control variable.

The control group is the group of subjects did not get any treatment that experiment group receives. The pot which is placed in the dark room is control group here.
