Answer:
answer is water molecules
Explanation:
The oxygen evolved during photosynthesis comes from water molecules.
According to the research, the statement "Linear molecules must be nonpolar, thus linear molecules cannot participate in dipole-dipole attraction" is true.
<h3>What are dipole-dipole attractions?</h3>
It is observed between a positive dipole of a polar molecule with the negative dipole of another, the atom with the highest electronegativity attracts electrons towards itself, forming a negative dipole around it.
In polar covalent bonds, the atom with the least electronegativity, the dipole formed has a positive charge, since it partially gives up its electrons.
Therefore, we can conclude that according to the research, the statement "Linear molecules must be nonpolar, thus linear molecules cannot participate in dipole-dipole attraction" is true.

The system of equation that represents this situation is y = 20x + 15 for day and night kernel and y = 30x + 5 for bark time hotel.
A linear equation is in the form:
y = mx + b
where y, x are variables, m is the rate of change and b is the initial value of y.
Let y represent the total charges for for boarding a pet in x days.
Day and night kennel charges $20 per day plus a one-time food fee of $15 to board a pet. Hence:
y = 20x + 15
Bark time hotel charges $30 per day plus a one-time food fee of $5. Hence:
y = 30x + 5
The system of equation that represents this situation is y = 20x + 15 for day and night kernel and y = 30x + 5 for bark time hotel.

Answer:
Make notes to easily remember certain things or make it easier to understand something. Organize your subjects and personal items such as binders, papers, notebooks, lockers etc. Make your notes and work personal, add notes for easy answer access and easier understandings of subjects. Make sure to use remembering tactics like the repeating of words or ideas, also make sure to reread or ask questions if needed. Study notes that you take down like they are flash cards to also help with remembering questions and there answers. Attendance is also very important for studying and remembering. If you miss a day try your best to get caught up and study more to get caught up.

<h3>How to interpret the two-way frequency table</h3>
<u>The students that like swimming</u>
From the table, we have the following highlights
- 24% students like swimming in grade 8
- 18% students like swimming in grade 9
<u>The students that like running</u>
From the table, we have the following highlights
- 17% students like running in grade 8
- 14% students like running in grade 9
<u>The students that like volleyball</u>
From the table, we have the following highlights
- 5% students like volleyball in grade 8
- 54% students like volleyball in grade 9
