How would you experiment to find out how much water this plant type needs for optimal growth

Answers

Answer:

The correct answer will be- by providing different amount of water to experimental groups.

Explanation:

The scientific experimental samples are divided into two groups: the control group in which the variable to be studied is kept constant and the experimental variable to which different amount of studied variable is provided.

In the given question, the scientific question is how much amount of water is required for the optimal growth of the plants. The variable to be studied is water, so different amount of water is provided to different pots like 10 ml, 20 ml, 30 ml and so on.  So the plant which will respond best to this amount will be the optimal concentration of the water required by the plant to grow.
You would pick amounts of water as your IV and do like 0 mL, 20 mL, 40 mL, and 60 mL as groups (for example, amount can be changed). Whichever had the best growth in the certain amount of time, with all other variables constant, would be it.

What was the main reason the Federalists wantedto replace the Articles of Confederation?
(1) The president did not have the power to veto
legislation.
(2) The legislative branch enacted an unfair tax
program.
(3) The Supreme Court refused to pay
Revolutionary War debts.
(4) The national government was too weak to
solve the nation’s problems.

Answers

Answer : Option 4) The national government was too weak tosolve the nation’s problems.

Explanation : The main reason for the Federalists wanted to replace the Articles of Confederation because they believed that the structure the Articles which were laid out did not provided enough power for the federal government to effectively solve the nation's problems. It projected the image of the federal government being weak for solving nation's problem.
The national government was too weak to solve the nation's problems. 

The Articles of Confederation were only meant to be temporary, like a stand in, until a better document, eventually known as the constitution, could be created.

Add 92.2 km to 9426 m and report the answer inkm.
92.2 km + 9426 m =
km
Help me plz

Answers

Answer:101.6

Explanation:

to convert m into km we have to divide it by 1000.so,

9426/1000=9.426km

92.2km+9.426km=101.626km.

Which of the following is not a phase change?melting of snow
evaporation of water from the ocean
condensation of water vapor to form clouds
hydrogen and oxygen gas combining to form water vapor

Answers

Answer : The correct option is hydrogen and oxygen gas combining to form water vapor.

Explanation :

Phase change : It is a change from one state to another state without changes in chemical composition.

Phase change such as solid to liquid, liquid to vapor, vapor to liquid, liquid to solid, vapor to solid, solid to vapor.

  • Melting of snow is a fusion process in which phase changes from solid to liquid.
  • Evaporation of water from the ocean is a evaporation process in which phase changes from liquid to vapor.
  • Condensation of water vapor to form clouds  is condensation process in which phase changes from vapor to liquid.
  • Hydrogen and oxygen gas combining to form water vapor, there is no phase change in this reaction because a gas combine with another gas to form a water vapor as a gas.
hydrogen and oxygen gas combining to form water vapor is the correct answer.

In a redox reaction, why does an element’s oxidation number decrease?

Answers

Element’s oxidation number decrease that because that element has received electrons from another element

Explanation:

a reduction in oxidation state is known as a reduction. Such reactions include the formal removal of electrons: a net gain in electrons moving a reduction, and a clear loss of electrons being an oxidation.

An oxidation-reduction (redox) reaction is a type of synthetic reaction that involves a transfer of particles between two species. An oxidation-reduction reaction is any synthetic reaction in which the oxidation number of a molecule, atom, or ion quarters by winning or missing an electron.
that because that element has received electrons from another element
