Which step in the process of photosynthesis is dependent on light energy?
A.splitting of water into hydrogen and oxygen
B.combining carbon and oxygen into carbon dioxide
C.splitting carbon dioxide into carbon and oxygen
D.combining hydrogen and oxygen to form water

Answers

Answer:

D. Combining hydrogen and oxygen to form water.

Explanation:

The process of photosynthesis which is dependent on light energy is the

combining of hydrogen and oxygen to form water.

Photosynthesis involves the reaction between carbondioxide and water to

form Starch and oxygen. The water molecules however have to be split

because of movement of electrons in which the water become oxidized and

carbondioxide reduced.

This process however have to be done in the presence of sunlight which

serves as a precursor.

Answers

Answer:

The answer to this question is "D" Some layers of the earth are liquid, and some are solid.

Explanation:

Core, mantle, and crust are divisions based on composition. The crust makes up less than 1 percent of Earth by mass, consisting of oceanic crust and continental crust is often more felsic rock. The lithosphere is composed of both the crust and the portion of the upper mantle that behaves as a brittle, rigid solid.

The option that correctly describes the compositional layers of the earth is : ( D ) Some layers of the earth are liquid, and some are solid.

ANSWER TWO QUESTIONS,
Test variable (independent variable):
Outcome variable (dependent variable):

Answers

These changing quantities are called variables. A variable is any factor, trait, or condition that can exist in differing amounts or types. An experiment usually has three kinds of variables: independent, dependent, and controlled. The independent variable is the one that is changed by the scientist. or tested in an experiment. For example, in a study looking at how tutoring impacts test scores, the dependent variable would be the participants' test scores, since that is what is being measured. An independent variable is defines as the variable that is changed or controlled in a scientific experiment. ... Independent variables are the variables that the experimenter changes to test their dependent variable. A change in the independent variable directly causes a change in the dependent variable. Either the scientist has to change the independent variable herself or it changes on its own; nothing else in the experiment affects or changes it. Two examples of common independent variables are age and time. There's nothing you or anything else can do to speed up or slow down time or increase or decrease age. the experimenter changes or controls and is assumed to have a direct effect on the dependent variable. ... The dependent variable is the variable being tested and measured in an experiment, and is 'dependent' on the independent variable. The variables in a study of a cause-and-effect relationship are called the independent and dependent variables.
The independent variable is the cause. Its value is independent of other variables in your study.
The dependent variable is the effect. Its value depends on changes in the independent variable. A test variable is a user-defined, name-value pair that stores and refers to information throughout a test and between tests. You can think of independent and dependent variables in terms of cause and effect: an independent variable is the variable you think is the cause, while a dependent variable is the effect. In an experiment, you manipulate the independent variable and measure the outcome in the dependent variable. used synonymously. used synonymously. However, they are not exactly the same: the outcome variable is defined as the presumed effect in a non-experimental study, where the dependent variable is the presumed effect in an experimental study. The dependent variable is the variable being tested and measured in an experiment, and is 'dependent' on the independent variable. An example of a dependent variable is depression symptoms, which depends on the independent variable (type of therapy).
An independent variable, sometimes called an experimental or predictor variable, is a variable that is being manipulated in an experiment in order to observe the effect on a dependent variable, sometimes called an outcome variable.
