When going from a slower medium to a faster medium, light is bent _____.
A. toward the normal line
B. away from the normal line
Answer:
B. away from the normal line
Explanation:
"when light travels faster, it bends away from the normal, since it is entering a less dense medium. when light travels slower, it bends towards the normal, since it is entering a denser medium (Socratic)."
I hope this helps! :)))

You see a worm crawling along the ground and wonder if scientists consider it living or nonliving. Which item below would not be true when classifying the worm as living or non‐living?
A worm can move so it must be living.
A worm can reproduce and make little baby worms (called wormlets) so it must be alive.
Worm’s pass dirt through their body pulling food out and discarding the stuff they don’t want so it must be alive.
If you cut a worm in half, it can re‐grow so it must be alive.
Answer: a. A worm can move so it must be living.
Explanation:
If a worm is moving it is classified as a moving worm also known to be living if moving.
A worm could reproduce therefore it is living.
Worms do pass dirt into and through there bodies to eat of the minerals and discarding things through and let out.
If you do cut a worm in half it may damage it but since it has basically two heads on girl one boy and cut in half it may split them up, and make damage but they will eventually grow back if the injuries are not severe.

In a reaction between iron and oxygen, the reaction slowed down when there was more rust (iron oxide) than either iron or oxygen. Which of the following caused this reaction to slow down?
A. products decreased
B. reactants decreased
C. surface area increased
D. temperature increased
Answer:
its a or B
hope this helps
Explanation:
The chemical reaction of the rusting can be slowed down if the reactants decreased. Therefore, option (B) is correct.
What is a chemical reaction?A chemical reaction can be described as a process that brings the chemical transformation of one chemical substance to another chemical substance. The chemical reactions cause chemical changes that involve the rearrangement of electrons in order to form and break bonds between atoms.
The substances which are primarily used in a reaction are called reactants. Chemical reactions yield products, which possess properties different from the reactants.
Chemical reactions take place at a certain rate of reaction at a given temperature, pressure, and concentration. The rates of reaction increase with the increasing temperature of the reaction as more activation energy will be available for collisions.
The rusting of the iron in which iron oxide is formed will slow down if the reactants (iron or oxygen) decreased.

(A.) conflict of interest and confirmation bias.
(B.) getting the inside scoop about a product, buying company stock, and making a lot of money.
(C.) sound and reliable science practices.
(D.) all the above.
"A scientist works for a drug company and runs experiments on their product with results that favor the company's product. This is an example of conflict of interest and confirmation bias." Thus, option A is correct.
What is a conflict of interest?Conflict of interest has been defined as the situational circumstances where the individual or the company tries to get benefitted from the actions and behaviors that present the outcomes in favor of them. This includes manipulative strategies and steps.
The scientist manipulates drug experiments and their products to favor the company and shows biased investigations and methods that benefit the company by profiting and getting something from the official work.
Therefore, option A. conflict of interest is seen in the case.

What is the basis of an organic molecule?
(A). The basic structure is the iron atom.
(B). The basic structure is the potassium atom.
(C). The basic structure is the carbon atom.
(D). The basic structure is a carbon monoxide molecule.
Answer:
I think c
Explanation:
Answer: C
Explanation: Its C because Life is based on carbon, organic chemistry studies compounds in which carbon is a central element. The properties of carbon make it the backbone of the organic molecules which form living matter. Carbon is a such a versatile element because it can form four covalent bonds.
1. reaction that releases heat

Which of the following is true with regard to sodium and potassium?
A
The both have three outer shell electrons.
B
They both have filled orbitals.
C
They tend to form anions.
D
They tend to form cations.
Sodium and potassium tend to form cations. Therefore, the correct option is option D among all the given options.
What is ions?An atom or molecule is said to be an ion if a number of the valence electrons have been acquired or lost, providing it a net negative or positive electrical charge. In other terms, a chemical species has an unbalanced ratio of protons (positive charge particles) to electrons (negatively charged particles).
Because there are more protons than electrons in a given species, cations are ions with a net positive charge. The equation for a cation is denoted by a superscript that includes the amount of the charge and the symbol "+" after the formula. If present, a number comes before the plus sign. If there is simply a "+" there, the fee is +1. Sodium and potassium tend to form cations.
Therefore, the correct option is option D.

If you have a parallel circuit with a battery (4 ohms), a light bulb (2 ohm), and a fan (3 ohms), how would you find the total resistance of the circuit?
Voltage is the same across each component of the parallel circuit. The sum of the currents through each path is equal to the total current that flows from the source. You can find total resistance in a Parallel circuit with the following formula: 1/Rt = 1/R1 + 1/R2 + 1/R3 +...
Answer:
resistance = 0.9230769230769231
Explanation:
The total resistance can be found by using the following equation:
1 / R = 1 / R1 + 1 / R2 + 1 / R3
