In an experiment, the parts that are kept the same are known as constants or controlled variables. These are the factors that are intentionally kept unchanged throughout the experiment to ensure that any observed changes in the results are caused by the independent variable being tested.

Bone is made of calcium, calcium is a mineral. But animal / human bone is still not a mineral. a mineral is 1. naturally formed, 2. inorganic 3. solid 4. with a specific chemical composition and 5. has characteristic crystal structure so a bone violates the second and fith characteristics

Yes, the color of light can affect crystal growth. For example, different colors of light can impact the rate of growth, size, and shape of crystals due to variations in energy levels and wavelengths. Light plays a role in influencing the arrangement of atoms during crystal formation.

The part of the experiment that is changed and tested is called the independent variable. This variable is manipulated or controlled by the researcher to observe its effect on the dependent variable.

The scientific term that could describe the group of prisoners who changed their diet in Goldberger's experiment is the "experimental group." This group would be compared to a control group to determine the effects of the changed diet.

Scientists hypothesize that volcanoes on Triton, one of Neptune's moons, are likely powered by a combination of tidal heating caused by the gravitational pull of Neptune and radioactive decay in Triton's interior. This combination of processes could generate enough heat to produce volcanic activity on the icy surface of Triton.

The independent variable is intentionally controlled by the experimenter. This variable is manipulated to determine its effect on the dependent variable.

An endothermic reaction is one that consumes heat.

The nucleus of the donor's egg, which contains the donor's genetic material, needs to be removed during the cloning process. This step is necessary to make room for the nucleus from a somatic cell, which will be inserted into the enucleated egg to create a cloned embryo.

Commonly used chemicals or compounds in the medical field include antibiotics (e.g. penicillin), analgesics (e.g. acetaminophen), anesthetics (e.g. lidocaine), and antacids (e.g. calcium carbonate). These substances are used for treating infections, pain relief, inducing numbness, and reducing stomach acid, respectively.

Dust particles are very small and light, allowing them to be easily lifted by air currents. The irregular shape of dust particles also creates surface area for air to exert force, causing them to float in the air for extended periods of time.

Lemon water is a beverage made by adding fresh lemon juice to water. It is often consumed for its potential health benefits, such as improving digestion, hydration, and providing a source of vitamin C.

Ernest Rutherford's experiment results showed that atoms have a small, positively charged nucleus at the center. He also discovered that most of the atom's mass is concentrated in the nucleus, and that electrons orbit the nucleus in a mostly empty space.

The one variable that is changed in an experiment to test a hypothesis is called the independent variable. This is the variable that the researcher manipulates or controls to observe its effect on another variable, known as the dependent variable.

The variable to measure when removing oil from sand is the oil concentration remaining in the sand after the removal process. This can be quantified by analyzing the oil content in the sand before and after the removal process to assess the efficiency of the oil-removal method.

without a hypothesis there is no experiment

Two important variables to control in an experiment are the independent variable, which is the factor being manipulated by the researcher, and the control variable, which is kept constant to prevent it from affecting the results. Controlling these variables ensures that any changes observed in the dependent variable are a result of the manipulated factor and not due to other influences.

Great

question as Milos is one of the Volcanoes that has shown promise in recent history for an eruption in our millennia.

Milos is a stratovolcano, exhibiting phreatic craters and lava domes from previous eruptions, approximately 80k years ago.

Conducting an experiment three times helps to improve the reliability of the results by reducing the impact of random variability. It allows for averaging out any inconsistencies and provides a better estimate of the true outcome. Additionally, repeating the experiment helps to identify any errors or inconsistencies that may have occurred during the initial trial.

The formula for calcium chloride is CaCl2. Calcium is a group 2 element with a 2+ charge, and chloride is a group 17 element with a 1- charge. To balance the charges in a neutral compound, two chloride ions are needed for every calcium ion, giving CaCl2.

The experimental variable that is measured for change is typically called the dependent variable. It is the variable that is observed, measured, or tested in an experiment to see how it responds to changes in the independent variable.

A controlled experiment is conducted where all variables, except for the independent variable, are controlled or kept constant. This helps to ensure that any observed changes in the dependent variable are solely due to the manipulation of the independent variable.
