Answer: A, the sun creates it's own light.
Explanation: The moon can't create it's own light, so the sun shines on the moon and it reflects, or "bounces" off. The sun is able to produce it's light by fusion, which also creates heat.

Which processes are involved in the chloroplast of a plant cell?
Photosynthesis Cellular respiration
Aerobic Respiration Anaerobic Respiration
Glycolysis Electron Transport
Krebs Cycle Electron Transport Chain
Light Dependent Reaction Calvin Cycle
Answer:
Chloroplast absorbs sunlight and it is used to make feed for the plant together with water and carbon dioxide gas. Chloroplasts are used to generate the free energy stored in ATP and NADPH via a photosynthesis process.
Explanation:
The site of photosynthesis action is chloroplast within a plant cell consisting of two chlorophyll molecules (PS1 and PS2), which have been embedded in the thylakoid membranes. The chloroplast consists of two chlorophyll molecules (photosynthetic pigments responsible for the green color of chloroplast). Each chlorophyll molecule absorbs light, caused to depart the chlorophyll molecules. This absorbs two electrons from each phenotype. PS2 electrons pass through the transportation chain for electron carriers, a series of redox reactions that release the energy used to synthesize ATP via Photophosphorylation/Chemiosmose (as the H+ ions diffuse through the stalked particles ATP, which changes the shape and catalysts, the electrochemical gradient diffuses down through the stalky particle ATP synthase).
Then these electrons replace the electrons lost in PS1. PS2 electron is replaced by photolysis electron, which when light strikes chloroplast, splitting the water into oxygen gas, H+ ions, and electron enzymes in the thylakoid space are catalyzed. The PS1 electrons combine to create NADPH with H+ ions and NADP (reduced NADP). These are the light-dependent photosynthetic reactions in chloroplasts. In the light-independent reactions, the NADPH and ATP are created. A pile of thylakoids is known as granum.
The light-independent processes take happen in the stroma. This is the site of carbon fixation; CO2 reacts with RUBP to generate GP (glycerate-3-phosphate) which is catalyzed by the enzyme RUBISCO (the most abundant enzyme in the world) (the most abundant enzyme in the world). The NADPH and ATP from the light-dependent processes convert GP to GALP (glyceraldehyde 3-phosphate). Two out of every 12 GALP molecules produced are used to synthesize glucose that can be employed either in breathing or in cellulose-forming condensation polymerization to add extra strength to the planted cell wall. The other GALP molecules are returned to RUBP.
(b) Sperm is produced in the testis. State the structures through which the sperm passes on its journey to fertilise the ovum.

Smoking Doesn’t Just Hurt Your Health
(excerpt)
The arguments about smoking are usually centered around its effects on the health of smokers and nonsmokers alike. Entire ad campaigns have been developed around the idea of educating smokers about the risk that smoking poses to their health. Chances are you’ve encountered the photo of that diseased lung in your health class. Lawsuits against tobacco companies have gained a lot of media attention. Cities have gone so far as to ban smoking inside buildings, restaurants, and bars. But have you ever stopped to think about what smoking does to the environment?
It is easy to guess that smoking might pollute the air. Did you know that tobacco smoke contains more than 4,000 chemicals? Fifty of those chemicals are known to cause cancer, and two hundred are known poisons. Think about the fact that 20 percent of Americans smoke. Can you imagine how many chemicals are released into the air each year?
Cigarettes also account for an estimated 1.7 billion pounds of trash each year. Some people say the ban on smoking indoors in some cities could contribute negatively to this statistic. Because people are smoking outside, the number of cigarette butts they leave behind may increase dramatically.
A.
Smoking pollutes the air in public places, such as buildings, restaurants, and bars.
B.
Smoking not only produces negative effects on human health but also on the environment.
C.
Smoking damages the environment more severely than it damages human health.
D.
Smoking increases water pollution when cigarette butts are dumped into waterways.
E.
Smoking harms wild animals by polluting and destroying their natural habitats.
Answer: B. Smoking not only produces negative effects on human health but also on the environment.
Smoking not only produces negative effects on human health but also on the environment is best suited thesis statement to this persuasive excerpt.
How smoking effects our body?
Smoking causes lung disease, pulmonary disease, emphysema, diabetes or many more problems.It might be cause throat cancer or mouth cancer. Cigarette have tobacco, carbon monodioxide, benzene, nicotine, formaldehyde types of chemicals which are extreme harmful for body as well as environment.
Smoking is harmful for body as well as environment. Tobacco smoke contains more than 4,000 chemicals. Fifty of those chemicals are known to cause cancer, and two hundred are known poisons. These all are spread over in air and that air intake by the non smokers.
Cigarettes also account for an estimated 1.7 billion pounds of trash each year, so it produces the pollution in air dramatically.
Hence, option 'C' is correct.

If cells come from other cells, then why aren't they all in the same phase
Answer:
1) interphase
The majority of cells were in the stage interphase. In interphase, the cell gets itself ready for Mitosis or Meiosis.
2)The cell types in a multicellular organism become different from one another because they synthesize and accumulate different sets of RNA and protein molecules. They generally do this without altering the sequence of their DNA.

Explanation: Climate change is causing the extinctions of species. But some species will have better chances of survive-al because they were created that way. So, humans for example will have a good chance of survive-al despite of climate change, because we are always innovating and changing, while most plants and animals, are used to one type of climate or region.

3. theory → a. The outer layer of the Earth is divided into plates that move due to convection currents under the surface.
2. hypothesis → b. If the amount of daylight increases plant growth, then plants will have higher rates of growth during the summer.
1. law → c. For every action or force in nature, there is an equal and opposite reaction.
Explanation:
THEORY
The scientific theory explains facts or the cause of natural phenomena and makes predictions about them. It is based upon direct observation and scientific methodology.
The theory is fundamental to science because it allows scientists to organize and understand observations.
HYPOTHESIS
A hypothesis is a prediction done by the researcher when trying to answer a problem question. It is a conjecture, which has not been verified yey, nor refused, and that requires corroboration. It is a possibility, but not a fact. The researcher performs the experiment and concludes if the hypothesis is rejected or accepted. The prediction must be objective, expressed in a comprehensive manner, and reflect a logical relation between the variables involved in the experiment.
LAW
Law is a statement that establishes a relationship between variables explaining the cause of natural phenomena. It is based upon empirical information and evidence obtained after many repeated experiments and observations. Many scientists agree with the statement and use it to perform a research project. A law cannot be changed.

If the population of moths is found to have 100% dark colored individuals, would it be possible for them to survive if humans came and cleaned up the pollution on the trunks of the trees; returning them to a light colored bark?
Why or why not?
Explain your reasoning.
Answer:
Decrease occur in the population.
Explanation:
It would be impossible for dark colour moth to survive if humans cleaned up the pollution on the trunks of the trees and returning them to a light colored bark because the dark colored moths can easily be seen by their predators. The dark colour of trunk helps the dark colored moths to hide from their predators so if the black colour of the trunk are turn into light colour so there is decrease occur in the population of black colored moths.
