Explanation:

Answer: Independent variable is the Vitamin C and the ashy skin is the dependent variable.

Explanation:

We can change or manipulate the independent variable of the reaction and such change can be observed on the dependent variable. The dependent variable yields the results of the experiment and changes in the dependent variable must be observed attentively to frame the results.

Here, vitamin C is the independent variable whose affect has to be observed on the ashy skin which is the dependent variable of the experiment. Steps of the experiment:

1. We can apply Vitamin C in a form of solution on the ashy skin.

2. Observe the changes on the skin directly and apply for 2-3 times in a day.

3. Observe the changes on the skin after a week.

Answer:

kinetic

Explanation:

Answer:

Heat and Light energy of course!

Explanation:

In order to use a stove correctly you need heat to cook things, and the light would be the fire. The answer is NOT kinetic energy. It's Heat and Light Energy

Answer:

EXERCISE

Explanation:

In an experiment, the independent variable is the variable that the experimenter changes or manipulates in order to bring about a measurable outcome.

In this case, an experiment is carried out to test the hypothesis that "exercise will affect the number of times a person can squeeze a clothespin in a certain amount of time". The experiment contained two groups (one group sits quietly before squeezing a clothespin as many times as possible and the other does 25 JUMPING JACKS before squeezing a clothespin as many times as possible).

The independent variable is the EXERCISE (jumping jacks) that was changed for each group in the experiment.

Answer:

B) Living things eat.

Explanation:

Not all living things have to eat. Living things, like plants, make their own food.

The following is not a necessary characteristic of a living thing: that they eat, which is present in option b, as the living organism grows, reproduces, and is made up of cells.

Living organisms are made up of cells, and there are many forms of living organisms, such as prokaryotic bacteria and complex multicellular animals, and all of them grow and reproduce. Living organisms such as plants don't eat like animals, but they do take part in the reproduction process to form new plants, and the living forms grow in size as they develop.

Hence, the following is not a necessary characteristic of a living thing: that they eat, which is present in option b, as the living organism grows, reproduces, and is made up of cells.

The rule for making a neutral atom that has no charge is - Electron (E) = Proton (Protons).

Neutral atoms are atoms that have no charge or zero charges. It is known that an atom has three sub-atomic particles; Proton, Neutron, and electrons. Protons have a positive charge, neutrons have zero or no charges and electrons have negative charges.

There are three conditions possible:

                            E = P

                             E < P

                           E > P

Thus, the correct answer is - Electron (E) = Proton (Protons).

Answer:

recent study out of the Weizmann Institute in Israel states that the number of bacteria may actually be very similar to the number of human cells in the body.

While this results in about 1.3 bacterial cell per human cell, the numbers may vary significantly from person to person and could change significantly with each defecation. They estimate that the range of bacterial cells goes from about 30 to 50 trillion in each individual. Women may also have a higher ratio of bacterial cells than human cells because they have fewer human cells, specifically red blood cells.

Answer:

To balance the food chain.

Explanation:

Mosquitoes actually play a big part in the food chain.. Animals such as frogs eat them, and what if other foods that frogs eat go out(Not saying it's gonna happen, its just a what-if)? They will have to resort to the mosquitoes. And if those were gone, the frogs would go out. Then a certain number of animals maybe maybe not would have to develop a new diet due to the extinction of frogs.

Answer:

Over the past several years, the misuse of opioids – ranging from prescription painkillers to black tar heroin – has reached epidemic proportions. In 2015, the Media Research Center reported that drug overdoses had surpassed motor vehicle accident fatalities nationwide for the first time. Since 1999, nearly 200,000 Americans have died from a prescription drug overdose. Heroin use increased in response to advocate and lawmaker efforts to restrict overprescribing, doctor shopping, and opioid sales via online pharmacies. As prescription drug overdoses fell from 2010 to 2015, the number of heroin overdoses tripled.

Opioids are synthetic or semi-synthetic substances originating from the poppy plant. Examples include heroin, Fentanyl, and prescription opioid painkillers, all of which operate in the same fashion, albeit with varying degrees of strength. Synthetic opioids are among the most dangerous and addictive. The synthetic opioid Fentanyl, for example, is 25 to 50 times more potent than heroin, which is a semi-synthetic substance.

The National Institute on Drug Abuse explains, “[Opioids] act by attaching to specific proteins called opioid receptors, which are found on nerve cells in the brain, spinal cord, gastrointestinal tract, and other organs in the body.” When substances attach to these receptors, they change how the brain perceives pain and instead produce feelings of euphoria. They also slow essential body functions, such as heart rate and breathing.

Answer:

cells and tissue

Explanation:

Cells and tissue are the most basic levels of organization involved when a bone heals.

Cell is the small unit of all living organism, observed in animal, plant, microbes etc; cells are unicellular in nature like bacteria cell, where as some are multicellular in nature like all higher eukaryotic organisms such as plants and animal cell.

The simplest form of cells are prokaryotic cells have a cell membrane, cell wall and cytoplasm where all of the metabolic processes occur, ribosomes needed for protein synthesis occur, and nucleoid which carry genetic information, reproduce by binary fission.

The eukaryotic cells contain a complex organization where it contain cell membranes, cytoplasm, ribosomes, and nucleus a house of DNA, rough endoplasmic reticulum , smooth endoplasmic reticulum for lipids, Golgi apparatus responsible for protein sorting and exporting.

It has mitochondria power house house of the cell, a cytoskeleton responsible for structure and passes information, and lysosomes or peroxisomes for waste digestion, vacuoles for water storage, chloroplasts for photosynthesis.

Answer:

The cell will swell up and eventually burst.

Explanation:

Cells swell if there’s more salt in a cell than outside it, the water will move through the cell membrane into the cell, causing it to increase in size. if too much water gets in, the cell will burst.
