Give reason. When the tip of a plant is cut, it does not grow tall.

Answers

Answer 1

Answer: The growth of the plant decides on the presence of plant hormone, auxin which develops in the roots and shoots. Auxins change the rate of elongation in plant cells, controlling how long they become. So, if the tips are removed, there is no auxin made and growth of the plant stops.

What law of motion corresponds with this statement?

"A rifle kicks."

first law
third law
second law

Answers

Answer:

3rd  lawl

Explanation:

a rifle kick is when you fire a projectile and you feel a force pushing against your hand. Rifles normally have heavier projectiles so there is more force pushing back against you. example, if you were sitting on a spinny chair with wheeles and your friend is sitting on another, and you push each other while on the chair, you will both go backward, but the lighter person will go back more. for every action, there is an equal and opposite reaction

that is the third law, also said as: "When one body exerts a force on a second body, the second body simultaneously exerts a force equal in magnitude and opposite in direction on the first body."

11) What volume will 0.75 mol of Oxygen gas (O2) occupy at 298 K and a pressure of 52.7 kPa?

Answers

Answer:

Volume = 35.3L

Explanation:

Use Ideal Gas Law (PV=nRT) and isolate for V (volume) by dividing both sides by P (pressure). You will then get the eqaution listed below and you can solve by using the method I used below.

V = nRT/P

V = (0.75kPa)(8.314)(298K)/(52.7kPa)

V = 1858.179/52.7

V = 35.3L

a sample of glucose contains 1.250x10^21 carbon atoms, how many atoms of hydrogen does it contain?

Answers

Answer:

Hydrogen = 2.5 * 10^21

Explanation:

Chemical Formula Glucose: C₆H₁₂O₆

One of the ways you could do  this is to notice that for every carbon atom there are two Hydrogen atoms. You can state this more formally by using the formula to set up a ratio: 12/6 = hydrogen to Carbon

So if there are 1.250 * 10^21 Carbon atoms in the Glucose sample, then there will be twice as many hydrogen atoms.

H = 2 * 1.25 * 10^21 = 2.5 * 10^21 atoms

You could do this more formally by setting up a proportion.

6 Carbon / 12 Hydrogen = 1.25*10^21 /  x         Cross Multiply

6*x = 12 * 1.25*10^21                                           Combine the right

6x = 1.5 * 10^22                                                  Divide by 6

x = 2.5 * 10^21

The Universal Space Agency wants to know the results of your Sim investigation. Write your report to the lead chemist, explaining why drops of liquid water appeared on the outside of the cold, but not the warm, soda can. Use evidence from your investigation in your explanation.

Answers

Answer:

due to warm temperature

Explanation:

Explanation:

There is water present in liquid form instead of liquid nitrogen on the outer side of the can because of the temperature present in the surrounding environment. The temperature around the can is little warm which is favourable for the water but not for the liquid nitrogen. The liquid nitrogen present in liquid state when the temperature of the surrounding is too cold. if it is warm, the liquid nitrogen starts boiling and converts into gaseous state so that's why the warmer temperature is responsible for the presence of water not the liquid nitrogen.

The ___ variable responds to the __ variable and goes on the Y-axis.
1. Dependent, Independent
2. Independent, Dependent
3. Control, Constant
4. Constant, Control

Answers

Answer: 1. Dependent, Independent The dependent variable responds to the independent variable and goes on the Y-axis.

Explanation: The independent variable is controlled or manipulated by the experimenter. For example, someone's age might be an independent variable. Other factors (such as what they eat, how much they go to school, how much television they watch) aren't going to change a person's age.The dependent variable is what you are measuring. For example, a test score could be a dependent variable because it could change depending on several factors such as how much you studied, how much sleep you got the night before you took the test, or even how hungry you were when you took it.

How that helps. :)

The dependent variable responds to the independent variable and goes on the Y-axis. Therefore, option A is correct.

What is dependent variable ?

In mathematical modeling, statistical modeling, and experimental sciences, there are dependent and independent variables. Dependent variables are so-called because, during an experiment, their values are examined on the assumption or presumption that they are governed by the values of other variables.

the dependent variable on other measurable variables As a result of an experimental manipulation of the independent variable or variables, these variables should change.

What you track in the experiment and what is impacted by it are both considered dependent variables. The independent variable affects the dependent variable's behavior. Because it "depends" on the independent variable, it is known as a dependent variable.

Thus, option A is correct.
