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.

a. meiosis produces two identical daughter cells just like mitosis
b. neither resemble mitosis
c. meiosis II resembles mitosis
d. meiosis is identical to mitosis, it just happens 2 times.
e. meiosis I resembles mitosis
Answers
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).

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.

List two examples of how chemical or nuclear energy can be transformed.
Answers
1. The sun transforms nuclear energy into heat and light energy.
2. Chemical reaction is a chemical substance that can be transformed to other forms of energy. As an example, when a fuel is burned the chemical energy of molecular oxygen is converted to heat, and the same is the case with digestion of food metabolized in a biological organism.
Answer:
Explanation:
for chemical energy is can be transformed in several ways since it is potential energy it can be transformed into kinetic energy or into electrolysis because batterys contains energy within.
nuclear energy can be transformmed into a fission reaaction which helps provide nergy to large cities or the fusion reaction which is the sun providing light for all our needs!
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.

C. A formula model shows size of the glucose molecule, but the 3D model does not.
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 :)

Answer:
Enzymes speedup the chemical reaction.
Explanation:
Enzymes are the molecules which are responsible for speedup of the chemical reaction. In this picture, we can see substrate attached to the active site of the enzyme. This enzyme speedup the chemical reaction and products are formed after completion of chemical reaction. When the chemical reaction is over, the products detached from the enzyme and no decrease occurs in the size of enzyme.
