Whats the difference between a mixture and a compound? Mixtures are impure and compounds are pure, but how are mixtures formed? Are they formed with elements combined are something else? Please help! Dont copy and paste

Answers

Answer 1

Answer:

A compound is chemically bonded whereas mixtures are not. Compounds have a set amount of atoms that are conjoined, maybe through the process of heat, acid, water, etc, but, mixtures two things roughly mixed together, not chemically bonded.

D. A formula model shows which atoms are larger but the 3D model does not.

Answer: # 1: c.  #2: d.  #3: a

Explanation:

#1 is C. because the equation for cellular respiration is C₆H₁₂O₆

+ 6O2 --> 6H20 + 6CO2 + ATP

This says the reactants (inputs) are oxygen and glucose and the products (outputs) are water, carbon dioxide, and ATP. 1 glucose molecule makes 6 carbon dioxide, so 3 glucose would make 18 carbon dioxide molecules.

#2 is D. because the law of conservation of matter states that matter cannot be created nor destroyed, so the weight before and after cellular respiration would stay the same, as the matter would not change.

#3 is A. because a model would show the exact way the molecules would be arranged, while a formula only tells you how many there are, not the way they would be made up.

Hope this helps :)

what would happen to your body of blood pressure didn't work as it should?

Answers

Answer:

Vision problems. Heart attack. Stroke.

Explanation:

Answer:

Many things.

Explanation:

Blood pressure is a needed thing in a body. It gets blood to your organs and everywhere that needs it. If it didn't work, many things could happen.

Too high BP(hypertension):

If your blood pressure is too high, it can cause ruptured vessels, heart attacks, strokes, heart failure, which is where the heart enlarges too much to continue pumping blood at the adequate pressure/speed, kidney disease/failure, which would be from damage to the arteries around the kidneys, vision loss due to damage to the vessels in the eyes, angina, which is chest pain due to narrowed vessels in the chest, some forms of which may cause heart attacks.

Too low BP(hypotension):

If you're experiencing hypotension, there are many things commonly associated with it. These are dizziness, fainting, nausea, blurred/fading vision, lack of focus, and fatigue. If hypotension becomes extreme, it can cause someone to go into shock, which is life threatening and can and will cause death.

Question: Does light have an effect on the rate of mitosis in a cell?
Hypothesis: If
then
Independent variable:
Dependent variable:

Answers

Answer:

Hypothesis: IF light is applied, THEN the rate of mitosis will increase

Independent variable: LIGHT

Dependent variable: RATE OF MITOSIS

Explanation:

Hypothesis is a testable explanation given to solve a problem or answer a question. It is usually in the IF, THEN format. A hypothesis of this experiment can read: IF light is applied, THEN the rate of mitosis will increase.

Independent variable is the variable that is changed or manipulated by the experimenter in an experiment. In this experiment, the independent variable is the LIGHT.

Dependent variable is the variable that is measured in the experiment. It is the variable that responds to changes made to the independent variable. In this experiment, the dependent variable is the RATE OF MITOSIS in a cell.

Answers

Answer:

The micrographs of cells shown in figure 8-3. what information about cells do these micrographs suggest is explained below in details.

Explanation:

Micrographs are the intensified images collected from small microscopes. Cell micrographs are often obtained from tissue specimens and show a constant mass of cells and inside compositions that are difficult to distinguish individually. It provides accurate images of the exteriors of cells and whole plants that are not imaginable by TEM. It can also be practiced for particle counting and size resolution, and method control.

b. neither resemble mitosis
c. meiosis II resembles mitosis
d. meiosis is identical to mitosis, it just happens 2 times.

Answers

C

Explanation


Meiosis 2 is similar to mitosis because it separates the chromosomes to have sister chromatids in each cell. In both processes, you are separating the chromosome and dividing the cell to make 2 cells out of 1 (the only difference is that in meiosis, you're doing that for 2 cells to get 4).
