Which of the following best explains why Mars' and Venus' surface temperatures vary, despite both planets having atmospheres that contain mostly carbon dioxide?(1 point)

Venus has a surface of high mountains which absorb heat.
Mars has a surface of red rocks and sand which reflect heat.
Venus has a thick atmosphere which blocks heat from the surface.
Mars has a thin atmosphere that cannot hold much heat.

Answers

Mars and Venus are the planets of the solar system and vary in their temperatures. Mars has a thin atmosphere that cannot much amount of heat. Thus, option D is correct.

What is the atmosphere of Mars?

Mars has been the fourth planet of the solar system that is also called the red planet due to its red appearance. It has more amount of carbon dioxide than oxygen gas. It comprises various gases and has a thin atmosphere.

The thin atmosphere of Mars unlike Venus cannot hold the heat and transmits it back to space. Venus has a thick atmosphere that traps heat and results in an increased surface temperature. The atmospheric particle of Mars cannot retain heat and hence vary in temperature.

Therefore, option D. Mars has a lower temperature than Venus due to its thin atmosphere.

I would prefer you to make a schedule in a day whenever you have time like if you're studying 5 hours a day then do maths for two hours and after that you have three hours left then take one hour for each subject like 1hr for Chemistry , 1hr for History and 1hr for Spanish so that you can study atleast 4 subjects each day. But remember that everyday you have to do maths for 2hrs and after that you can randomly change the subjects like if you have completed 1 chapter from history then you can study physics. I didn't sent you a link or website but it's just a simple advice from me for being a topper. So I hope it will help you

Organize your self like really.
try to do your homework while you’re in class so when your classes for the day are over you have plenty of free time to study or do whatever you want. That’s what helps me in school

A statement in the introduction read, “All other factors remained the same between the two groups.” Make a list of factors that must remain constant in the experiment.

Answers

The factors that must remain the same in an experiment are known as control variables.

In order to conduct a proper experiment, there must be 3 kinds of variables. These are:

Dependent variableIndependent variableControl variable

A dependent variable is a variable that the experiment seeks to observe, this variable is expected to change in value throughout the experiment and depends on other variables. An independent variable is one that the researcher changes throughout the experiment in order to see what effect it will have on the dependent variable.

The variables referred to in the question are control variables. Control variables are the factors that must remain constant in an experiment. This is to ensure that when we measure a change in the dependent variable, we know to attribute it to the correct cause of the change. The presence of control variables helps to ensure a valid experiment and limits the influence of other factors on the outcome.

How does hydrogen peroxide get into cells?

Answers

Answer:

when a cell creates hydrogen peroxide, it stores it inside the cell's specialized organelles, called peroxisomes, which contain hydrogen peroxide-busting catalase.

Explanation:

Hydrogen peroxide gets into the cell with the help of an enzyme called peroxide dismutase, which significantly catalyzes the process of dismutation of superoxide radicals in order to synthesize H2O2.

What is Hydrogen peroxide?

Hydrogen peroxide may be defined as a liquid chemical that typically contains hydrogen and oxygen and is generally utilized for bleaching and as an antiseptic.

Hydrogen peroxide is consistently produced in the cell and then stored in the organelle known as the peroxisome. The cells then eliminate the excess amount of hydrogen peroxide (H2O2) with the action of an enzyme called catalase. And gest dissociates into the water (H2O) and molecular oxygen (O2).

Therefore, the process of production and digestion of hydrogen peroxide in the cell is well described above.

What is the process of nitrification?

Bacteria converts ammonia into nitrites and nitrates that plants can use.
Fungi convert nitrogen in dead plants into ammonium, which converts proteins into ammonia.
Nitrogen is converted into a useable form through lightning fixation.
Plant enzymes reduce nitrogen compounds into amino acids.

Answers

Answer:

Bacteria converts ammonia into nitrites and nitrates that plants can use.

Nitrification is a microbial process by which reduced nitrogen compounds (primarily ammonia) are sequentially oxidized to nitrite and nitrate. Ammonia is present in drinking water through either naturally-occurring processes or through ammonia addition during secondary disinfection to form chloramines.
