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

review the micrographs of cells shown in figure 8-3. what information about cells do these micrographs suggest, which might not be accurate?
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.

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 :)

List two examples of how chemical or nuclear energy can be transformed.
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?
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.

Answer:
Inflammation
Explanation:
Innate Response:
"The innate immune system is the body's first line of defense against germs entering the body. It responds in the same way to all germs and foreign substances, which is why it is sometimes referred to as the "nonspecific" immune system. It acts very quickly: For instance, it makes sure that bacteria that have entered the skin through a small wound are detected and destroyed on the spot within a few hours. The innate immune system has only limited power to stop germs from spreading, though. The innate immune system consists of: Protection offered by the skin and mucous membranes AND Protection offered by the immune system cells (defense cells) and proteins."
Acquired Response:
"The adaptive immune system takes over if the innate immune system is not able to destroy the germs. It specifically targets the type of germ that is causing the infection. But to do that it first needs to identify the germ. This means that it is slower to respond than the innate immune system, but when it does it is more accurate. It also has the advantage of being able to "remember" germs, so the next time a known germ is encountered, the adaptive immune system can respond faster. The adaptive immune system is made up of: T lymphocytes in the tissue between the body's cells AND B lymphocytes, also found in the tissue between the body's cells AND Antibodies in the blood and other bodily fluids."
I'm sure it's Inflammation, so here is the definition for that:
"Inflammation refers to your body's process of fighting against things that harm it, such as infections, injuries, and toxins, in an attempt to heal itself. When something damages your cells, your body releases chemicals that trigger a response from your immune system."

Explanation:
Answer:
Repairing or reparative phrase begins within the 1st few days after the bone fracture last for about 6 to 8 weeks. During this time, the body develops cartilage tissue in and around the fracture site. Children's bones normally heal faster than adults.

O C. Food, shelter, and water
O D. Electricity, water, and farmland
Please help
Answer:
C is the correct answer
Answer:
Food, water and shelter are the three basic things the human population must have in order to survive.
Explanation:
The temperature of the interior of the human body is about 37oC (98.6oF), regardless of the air temperature. Explain the importance of constant body temperature given the role of enzymes as catalysts in the body.
It is critical that we sustain an optimal temperature for our body's enzymes. When it gets too hot, our enzymes denature and become inactive/lost their function. If the temperature is too low, the enzymes will become ineffective.
What is homeostasis?Homeostasis is the state of constant internal, physical, and chemical assumption is supported by living systems in biology.
This is the state of the organism's optimal functioning, and it includes many variables, such as core temperature as well as fluid balance, getting kept within certain pre-set limits.
Enzymes can only function when the body's temperature remains constant. As a result, homeostasis becomes an important part of the body's metabolism.
Homeostasis maintains optimal conditions for enzyme action and all cell functions throughout the body.
It is the preservation of a constant internal environment in the face of changing internal and external conditions. These include blood glucose concentration control in the human body.
Thus, having an optimum temperature is essential in functioning of enzymes.
