define the following terms:dispersion and refraction

Answers

Explanation:

Dispersion of light is the splitting of white light into its constituent colors due to the refractive index of the surface and the wavelength of the light. If the light entering the prism is not of a single colour then the emergent beam also has different colours arranged in a definite order.

In physics, refraction is the change in direction of a wave passing from one medium to another or from a gradual change in the medium. Refraction of light is the most commonly observed phenomenon, but other waves such as sound waves and water waves also experience refraction.

Dispersion is defined to be the spreading of white light into its full spectrum of wavelengths. Refraction is responsible for dispersion in rainbows and many other situations. The angle of refraction depends on the index of refraction, as we saw in The Law of Refraction.

Help asap !!!! Which of these statements is true of the brightest stars? (1 point)
O They are yellow stars.
O Many are supergiants
O Several are white dwarfs.
O Each is part of the main sequence.

Answers

Answer:

Many are supergiants.

Explanation:

A star's size and core temperature determine its brightness. The brightest stars tend to be blue or blue white. Supergiants and red giants are in the region above the main sequence of stars, so that isn't true. Red are the dimmest. Yellow stars are in the middle of that spectrum. White Dwarfs are dimmer than the Sun, red giants and blue supergiants.

Which of the following correctly describes the two phases of the cell cycle?
A. Cells grow and develop during interphase. Cells reproduce during the mitotic phase.
B. Cells grow and develop during the mitotic phase. Cells reproduce during the interphase.
C. The nucleus of a cell divides during interphase. The cytoplasm of a cell divides during mitotic phase.
D. The nucleus of a cell divides during mitotic phase. The cytoplasm of a cell divides during interphase.

Answers

Answer: the answer is A

Explanation:

Cell cycle refers to the series of processes that leads to the growth/development and division of a cell. The cell cycle uses MITOSIS for cell growth. Mitosis comprises of two distinct stages namely: INTERPHASE AND MITOTIC PHASE. The interphase is referred to as the resting phase of the cell in which the cell grows and develops.

On the other hand, MITOTIC PHASE is the stage where the actual division of the nucleus (karyokinesis) and cytoplasm (cytokinesis) generally called CELL DIVISION occurs. Therefore, the cell reproduces i.e. one cell forming two, in the mitotic phase.

can someone pls help me

Answers

Answer:

16. mitochondria

17. lysosomes

18. smooth Endoplasmic Reticulum

19. golgi body

20. golgi complex

Explanation:

16. Mitochondria are double membrane-bound cell organelles responsible for the supply and storage of energy for the cell

17. While cells mainly use lysosomes to dispose of trash. Sometimes they simply hang onto their trash, performing the cellular equivalent of sweeping it under the rug

18. Are the storage organelle, associated with the production of lipids, steroids, and also responsible for detoxifying the cell.

19. The Golgi body is the sorting organelle of the cell. Proteins are transported from the rough endoplasmic reticulum (RER) to the Golgi.

20. is responsible for sorting and correctly shipping the proteins produce the ER. Just like our postal packages, which should have a correct shipping address, the proteins produced in the ER should be correctly sent to their respective address. It is a very important step in protein synthesis.

a signal molecule which can bind to an enzyme and shut down its activity by altering the shape of the enzyme.

Answers

Answer:

Enzyme inhibitor

Explanation:

An enzyme inhibitor is a molecule that binds to an enzyme and decreases its activity. By binding to enzymes' active sites, inhibitors reduce the compatibility of substrate and enzyme and this leads to the inhibition of Enzyme-Substrate complexes' formation, preventing the catalysis of reactions and decreasing the amount of product produced by a reaction.

What is the equation for a photosynthesis???????????????

Answers

[tex]\large\huge\green{\sf{Answer:-}}[/tex]

6CO2 + 6H2O → C6H12O6 + 6O2.

The equation for photosynthesis is given as:

6CO₂ + 6H₂O ----> C₆H₁₂O₆ + 6O₂

Photosynthesis

Photosynthesis is the process by which green plants manufacture their food from carbon dioxide and water in the atmosphere using sunlight as an energy source.

Carbohydrates are produced while oxygen is given off as a by-product in photosynthesis.

During photosynthesis, the energy from the sunlight is trapped by the chlorophyll found in the chloroplast and used to energize the reactions involved in photosynthesis.

Find the unknown side (w) of the rectangular solid. Please help.. Read the story.Racing to RaceCarlo stopped to rest for a minute and tried to catch his breath. Hed been running for so long that he had pains in his side and his legs were beginning to hurt. He hunched over and tried to expand his lungs, but it was like trying to suck air out of a bicycle tire. His body was too exhausted to even allow him to take a deep breath, and he started to wheeze again.Great, he thought, let me just add asthma to my expanding list of ailments. I cant believe that I cant even jog two miles without completely collapsing! He finally gave in to his aching body and laid down on the grass to recuperate. He closed his eyes and tried to imagine himself running on the school track in the 1,600-meter race. He pictured himself running steadily toward the finish line, running effortlessly like a cheetah in the jungle. He was so lost in thought that he didnt even hear Meiya approach.Hey sleepyhead, what are you doing napping on Seans lawn in the middle of the day? Meiya asked playfully.Carlo quickly sat up, breathing normally now and feeling a little embarrassed. I am trying to get in shape to try out for track, but I cant even run two miles, he said dejectedly.Wait, how many months are you out of surgery? Didnt you just finish rehab last week? Meiya asked. You cant expect to run two miles the first day.It had been six months since Carlos surgery and he specifically remembered the doctor telling him he could start running after six months. But he thought about what Meiya had said and realized she had a good point. After his surgery, the doctor did say rehab would be crucial to his recovery but that it would take time for him to gain back full use of his leg. He thought about how a baby had to learn to walk before it could run. He remembered when his nephew was learning to crawl; within days it seemed like he was walking. Running didnt come right away, Carlo remembered. He realized it was the same with his therapy. The maximum he had run in the past month was one mile on the treadmill, so he realized that Meiya was probably right. He would have to work at building up his endurance and set more realistic goals for himself. As he thought about what he had already accomplished, he started to smile and felt like a weight was being lifted off his shoulders. He realized that he had run almost a mile and a half before his body started to protest and if he kept working hard, he could get back to where he was before his accident.Since when did you get so smart, Dr. Meiya? he teased. Do you want to race to the next mailbox?Youre on! she challenged and took off running at full speed........................................................Part AWhat is a central theme of Racing to Race?A.

Carlo pictures himself winning a big race on the school track team; when he realizes that he may not be able to run, he is very discouraged and disappointed.B. Meiya knows that she is faster than Carlo, so she does her best to encourage him and also lets him win a race between them to boost his spirits.C. Carlo is impatient about his ability to train for track tryouts, but after his conversation with Meiya, he realizes it will take time and work to heal his injury and fully recover.D. Carlo realizes that he may not be able to compete on the school track team but also discovers that, with time, he will still be able to participate in a sport he loves.
