A mineral forms from water at the edge of a lake. Which statement best describes this mineral? The mineral formed from lava. The mineral formed through evaporation. The mineral formed when hot water cooled. The mineral crystallized from magma.
Answer:
The mineral formed through evaporation.
Explanation:
Minerals are inorganic substances that occur naturally i.e. not man-made. These minerals are formed in different ways in nature. One of those ways is through EVAPORATION.
Since water dissolves a lot of substances including the particles of these minerals, the mineral components can be found in a dissolved state in water bodies e.g lakes, oceans etc. However, when heat increases and the water molecules evaporate (change to gas), the dissolved minerals in these water bodies crystallize out.
This is what happens when minerals form at the edge of a lake. The water from the lake evaporates leading to the formation of minerals.
Answer:
The mineral formed through evaporation.

How could increasing the number of plants help you decrease error in the experiment? Check all possible reasons.
It would increase the sampling error.
It would reduce the significance of any single measurement error.
It would make calculations easier.
Having more data would make the average height less affected by one or two plants that are randomly shorter or taller.
It would make a plant’s death less of an issue.
Answer: Increasing the number of plants in an experiment will help decrease the error, because you have more test subjects to run the test on.
Explanation:
The more subjects that you have have the more tests you can run, this will give you a chance to get more accurate and consistent results. When completing an experiment, you normally have to run 5 or more tests in order to get a goos set of data. So by increasing the number of plants you test on, you'll be able to get a better set of data.
Why is it important for molecules to able to travel into and out o your body's cells?
The function of the transport proteins is to maintain the internal environment of the cell's salt, nutritional, and protein balance within a range that ensures the survival of the cell and the organism.
What is importance of a molecule to move across the cell?Biology places a great deal of importance on the passage of substances into and out of cells (for example, nutrients into and poisons out), as without it, no cell and hence no organism could survive for very long.
Moving chemicals throughout the body is essential for living cells. Transporting chemicals into and out of cells is necessary.
Examples include oxygen, carbon dioxide, and dissolved food. Active transport, osmosis, and diffusion are used to accomplish this.
Therefore, transport of a molecule into and out of cell is important to functioning of cell.

why you add water to Sulphur dioxide and put a blue Litmus Paper in it why does it turns red
Answer:
Because it produce weak acid and acid turns blue lithmus paper to red.
Explanation:
Sulphur dioxide SO2 react to added water to produce acidic product.
When sulphur dioxide react with water, it produce sulphurous acid H2SO3 which is a weak acid.
One of the properties of acid is that they turn blue lithmus papper to red, because the product is an acid, blue lithmus papper turns to red.

You are conducting a photosynthesis experiment to determine how much oxygen is produced over a 24-hour period of time. You are measuring the oxygen production every hour for 24 hours.
Answer:
Measure only daytime.
Explanation:
It is useless to measure the oxygen production every hour for 24 hours because oxygen is produced during day time due to the presence of photosynthesis process. Oxygen is produced in large amount during photosynthesis, some oxygen is used in respiration while the remaining diffuse out from plant body through stomata. After vanishing sunlight, the photosynthesis process stop and no production of oxygen occur. So only measure oxygen production at daytime as compared to every hour for 24 hours.

Describe ways in which a healthy artery differs from an artery affected by coronary heart disease
Answer:
A healthy artery is wider and has no blockages. The lumen (which is the hole in the centre of the artery), is open and clear. This means there is more blood flow. An artery of a person suffering from coronary heart disease is often blocked, usually by a fatty deposit. This means the blood does not flow as well. (See diagram, in which I would draw two arteries, one with a blockage of fatty deposit, one clear and healthy).

Answer:
the date
Explanation:
A tide table shows the date, time, and height of the predicted tides. The type of tide that the given table represents is mixed semidiurnal.
What is a mixed semidiurnal tide?A mixed semidiurnal tide is a tide that has two high tides and two low tides of different magnitudes in each day. The interval between consecutive high tides or low tides is almost the same.
The height of the tides changes every day due to the gravitational pull of the Sun and the Moon on the Earth's ocean water. The influence of the Moon on tidal patterns is more significant than that of the Sun.
Therefore, a mixed semidiurnal tide is the one with two high and two low tides of different magnitudes in each day, which is represented by the given tide table. All of these characteristics indicate a semidiurnal tide pattern.
