When a person bends a glow stick a small chamber inside it breaks releasing a substance that reacts with other substances inside a glow stick the reaction takes place causing the glow stick to glow. What type of energy transformation is this
Answers
Answer:
B i have done this before and it went on my tounge
Explanation:
The energy transformation in a glow stick is a chemical to light energy transformation.
What happens when the chamber inside the glow stick is bent?When the chamber inside the glow stick is bent, a small glass vial containing a chemical mixture breaks, and the chemicals inside mix with each other. This chemical reaction results in the production of light energy in the form of a glowing light stick.
The chemical reaction inside the glow stick involves the oxidation of a dye molecule, which releases energy in the form of light. The dye molecule is activated by the energy released from another chemical reaction that occurs between hydrogen peroxide and a phenyl oxalate ester. This chemical reaction releases energy in the form of heat, which excites the dye molecule and causes it to release light.
Therefore, the energy transformation in a glow stick involves the conversion of the potential energy stored in the chemicals inside the glow stick into light energy. This is an example of a chemical to light energy transformation.

In what direction do substances diffuse across the cell
membrane?
Answers
Answer:
Since diffusion moves materials from an area of higher concentration to the lower, it is described as moving solutes "down the concentration gradient." The end result of diffusion is an equal concentration, or equilibrium, of molecules on both sides of the membrane.

Two true-breeding stocks of pea plants are crossed. One parent has red, axial flowers and the other has white, terminal flowers; all of the first generation of the offspring have red, axial flowers. The genes for flower color and location assort independently. If 1,000 second generation offspring resulted from the cross, approximately how many of them would you expect to have red, terminal flowers
Answers
Answer: 750
Explanation:
Based off the first two sentences, we can conclude that red is the dominant allele and white is the recessive allele.
Let's say R = red and r = white.
The genoytypes of the parents are RR and rr. The genotype of the first generation are all Rr
The punnet square for the second generation is:
R r
R RR Rr
r Rr rr
We can see 3/4 crosses give us red. Now we can multiply 3/4 and 1000 to get 750.

A. Biomass
B. Solar
C. Wind
D. Oil
Answers
Answer:
Both solar energy and wind energy are beneficial to soil quality. They are not using fossil fuels that both harm the soil with digging and fracking, but also are not being burnt which harms the air and can create acid rain. Both solar and wind are using nature to benefit the world. As long as the sun keeps burning and the world turning, we will continue to be able to use them.

From the markings that you had written and erased on your graph, it seems that you already have an idea of what you're supposed to do. Is it that you're having trouble scaling your graph on the provided sheet given the particular data? Or do you have a conceptual question with respect to the instructions?
I've provided the image of the graph according to my understanding of the instructions as stated in 1 and 2, and I've also attached the corresponding Excel spreadsheet that I used to create the graph. While the blank grid that you've attached doesn't scale identically to my graph, it should be possible to transpose the necessary elements into your grid to an acceptable approximation.
That said, please feel free to let me know if you have any clarifications, comments, or questions.
