Answer:
Non polar molecules are symmetric with no unshared electrons. Polar molecules are asymmetric, either containing lone pairs of electrons on a central atom or having atoms with different electronegativities bonded.
Explanation:
When things are different at each end, we call them polar. Some molecules have positive and negative ends too, and when they do, we call them polar. If they don't, we call them non-polar. Things that are polar can attract and repel each other (opposite charges attract, alike charges repel).

Environmental conditions caused the differences in flower color.
The most likely conclusion that can be made for the change in flower color is that genetic factors caused the differences in flower color.
According to this question, three plants are grown in the same environmental conditions with equal sunlight, water, and space to grow.
However, despite the uniformity in the environmental conditions received by each plant, one plant grew to have a purple flower while the other two grew white flowers.
This difference in flower color is likely caused by the inherent genetic factors of each plant rather than environmental factors because they were treated the same.

Which energy reactions occur in eukaryotic cells and are exact opposites of each other?
Answer:
Cell respiration and photosynthesis
Explanation:
In photosynthesis, organisms make high-energy compounds (glucose for example) by using carbon dioxide (CO2) and produce oxygen. In cellular respiration, organisms breakdown glucose and other compounds through consuming oxygen and produce CO2.

Explain what TWO forces cause Earth’s water to bulge?
Answer:
Gravity and inertia act in opposition on the Earth's oceans, creating tidal bulges on opposite sites of the planet. On the “near” side of the Earth (the side facing the moon), the gravitational force of the moon pulls the ocean's waters toward it, creating one bulge.

Which is an example of a limiting factor that is dependent on population size?
Answer: Food can be an obvious answer because people will not survive without food so they will die. And death means there will be a decrease on population size. So food can be a limiting factor that is dependent on population size.
Answer:
A limiting factor that depends on propulation size is called a density-dependent limiting factor.
Density- dependent limiting factors include: competition, predation, parasitism and disease.

A single base substitution mutation is likely to have a less deleterious effect when the base change exhibits which of the following results
A single base substitution mutation will be the least likely to cause a deleterious effect when the base change produces the same amino acid as the original.
What is a silent mutation?This scenario is what we call a silent mutation. What this means is that the mutation is almost undetectable due to its not affecting the protein that it will help to form.This is possible thanks to how the genetic code operates, different codons are able to code for the same amino acid.Therefore, there are mutations that do not affect the amino acid or the protein.Therefore, we can confirm that a mutation will have no negative effects if it is a silent mutation, meaning that the substitution of a base pair happens to code for the same amino acid as the original.

A rise in __________ released from the sarcoplasmic reticulum allows actin to bind to myosin and cause a contraction, which requires __________ energy.
A rise in CALCIUM released from the sarcoplasmic reticulum allows actin to bind to myosin and cause a contraction, which requires ATP energy. ATP is the energy coin of the cell.
Adenosine triphosphate (ATP) is the energy coin that cells use to carry out many metabolic reactions (e.g., reproduction, motion, differentiation, etc).
The sarcoplasmic reticulum is an organelle located inside muscle cells similar to the smooth endoplasmic reticulum.
This organelle (sarcoplasmic reticulum) acts to store calcium which is required during muscle contraction.

Instructions
Introduction
Follow the Procedure below. As you complete the lab, take notes about the lab so you can participate in the discussion. In this laboratory exercise, you will design an experiment to test how different materials reflect or absorb light.
Procedure
Part 1: Formulate a Hypothesis
1. Keep these questions in mind as you develop your hypothesis:
• Do some colors absorb more light than others?
• Do some materials absorb or reflect more light than others?
• How could you indirectly measure the amount of sunlight absorbed by an object?
2. Write a hypothesis, in if...then format.
Part 2: Design an Experiment
3. Design an experiment that tests the absorption and reflection of different materials.
4. Create a list of materials and a procedure to test your hypothesis.
5. Record your idea in your lab report for discussion. Note that you do not need to perform the experiment.
When you have finished, you will discuss with your classmates through a threaded discussion board. Print the Grading Rubric for the Threaded Discussion Board Activity and review the contents. Your teacher will use this rubric to grade your participation in this discussion.
ASSESS
Discussion: Energy Absorption/Reflection 1 (Online)
Read the discussion prompt and carefully write your response. Remember:
What you type here is public. A good rule of thumb is to only post things here that you would be
comfortable communicating in person.
Responses should be well written (use a spell-checker) and clearly address the issue being discussed. You
may wish to write your response in a word processing program, and then copy and paste it into the topic
response box.
Your teacher will review postings regularly. Any postings containing foul language or inappropriate topics
will be removed, and the posting student will be referred to the administration. If you are in doubt about
whether something is appropriate to post, either ask your teacher first, or just don’t post it.
Review the Grading Rubric for Discussion Board Activity. Your teacher will use this rubric to grade your
