The process of determining relative age is called ____________.
Group of answer choices
relative dating
absolute dating
exact dating
rock
Answer:
-- I can't be too sure, but... --
Relative dating
Explanation:
Determination of the absolute age of rocks and minerals using certain radioactive isotopes.
Relative Age: The age of a rock layer compared to other layers. It can be determined by looking at the position of the rock layers.
Relative Dating: Rocks and structures are placed in order from the age of older to younger.
These two seem to be from the same section and they connect as well, so I believe "Relative Dating" is your answer but I could be wrong nevertheless I hope this helps you!

The outline of a partial periodic table is shown.
Zinc is a metal. In which section of the partial periodic table is zinc located?
Section 1
Section 2
Section 3
Section 4
Answer:
I think section #3
Explanation:
When i was in science class in my memory it was always in that area
Zinc is a metal. Zinc is present in section 2 of partial periodic table.
What is periodic table?Periodic table is defined as an arrangement of all the elements known to man in accordance with there increasing atomic number and recurring chemical properties.
It is also defined as tabular arrangement of 118 known elements.
Metals are defined as any of a class of substance characterized by high electrical and thermal conductivity as well as by malleability, ductility and high reflectivity of light.
Zine is a metal with high conductivity. It is a very good conductor of electricity.
Thus, Zinc is a metal. Zinc is present in section 2 of partial periodic table.

Explanation:
Alanine is an amino acid with the formula C3H7NO2. How many atoms in all are in each molecule of alanine?
Answer:
12
Explanation:
13 atoms in all are in each molecule of alanine.
To find the total number of atoms in one molecule of alanine, we count the atoms for each element in the chemical formula.
Alanine has the molecular formula [tex]C_3H_7NO_2[/tex]:
3 carbon atoms ([tex]C_3[/tex])
7 hydrogen atoms ([tex]H_7[/tex])
1 nitrogen atom (N)
2 oxygen atoms ([tex]O_2[/tex])
Adding them together, we get:
3 + 7 + 1 + 2 = 13 atoms.
Adding them together, we get 3 + 7 + 1 + 2 = 13 atoms in one molecule of alanine. These atoms are arranged to form the chemical structure of the alanine molecule, which is an essential building block of proteins in living organisms.

lan wonders if sunscreen lotion will dry out if it is exposed to light. The table below shows what happens when different types of light hit the sunscreen
Based on this information, which type of light is more likely to dry out the sunscreen?
a
The ultraviolet light is more likely to dry out the sunscreen because the ultraviolet light bounces off of the sunscreen, which means that it has more energy.
b
The X-ray light is more likely to dry out the sunscreen because the X-ray light can pull energy out of the sunscreen when it passes through the sunscreen.
c
There is no way to know because they are two different types of light, and different types of light can change material in different ways.
d
Neither type of light is likely to dry out the sunscreen because the sunscreen does not take in energy from either the ultraviolet light or the X-ray light.
Sunscreen does not absorb any kind of light especially ultraviolet light and x-rays. They protect skin from these lights. Hence option D is correct.
What is sunscreen?Sunscreen lotion is a chemical which is used to protect skin from hazardous lights. Sunlight consists of ultraviolet light and X-rays which causes damages to skin. They even damage the DNA of humans.
Sunscreen is made of some nanoparticle formulation. They are capable of screening the skin from the hazardous light. The nanoparticles in the lotion will enter the cell without causing any toxicity and will form a protective coating around the nucleus.
Therefore, either type of light is likely to dry out the sunscreen because the sunscreen does not take in energy from either the ultraviolet light or the X-ray light. Hence, option D is correct.
