A mixture of iron, salt and sand can be separated using a magnet, water, a filter and a hot plate. Think about this separation. The separation of this mixture
Answer:
Explanation:
This is an example of a mixture which can be separated with simple separation techniques based on the physical properties of the mixtures.Magnetism, and filtration and evaporation
Iron is a magnetic material,but salt and sand are not,Therefore,the iron can be separated from the mixture with the use of magnet.
Salt and sand are mixable.But salt is soluble in water,but sand is not.Therefore by adding the sand and salt to water,the salt will dissolve,in the water(solvent) to form a salt solution. But the sand can be separated out of the solution by filtration with the filter paper inserted into a funnel which allows the salt solution to pass through,while restricting the sand.
The sand would be removed by the filter paper,while solution passes through.
The salt solution and some sand residues is placed in evaporating dish and heated at low temperature. The water from the solution evaporates,leaving the salt behind.
A combination of two are more substances that is not chemically combined is called a mixture.
In order to separate a mixture of iron, salt and sand, we need a magnet, water, a filter and a hot plate. The magnet is brought close to the mixture and all the iron is removed.
Next, water is added. The water will dissolve the salt while the sand will settle beneath the vessel. The solution can now be filtered and the sand is removed. To recover the salt, the solution is heated using the hot plate until all the water is evaporated and the dry salt is recovered from solution.

Which of these is a scientific hypothesis about the growth of a plant? A Plants make a pretty decoration in the house. B It's fun to watch this plant grow. C Plants grow best when they are happy. D This plant will grow best in sunlight.
Answer:
D. Plants grow best in sunlight.
Explanation:
The other answers can't be scientifically proven, therefore they would not make a good hypothesis. A hypothesis is a statement that can be tested and verified.
Plant will grow best in sunlight. So, the correct option is (D).
What is the scientific hypothesis about the growth of a plant?According to the evolution-immunity hypothesis in ecology, fast-growing plant species should suffer more from herbivores and pathogens than slow-growing species. Tests of this hypothesis have focused on above ground plant tissues, herbivores and pathogens. This should also apply to route defense.
When the amount of fertilizer applied to the plants is increased, the growth which is the height of the plant increases. As the amount of fertilizer increases, plant growth increases.
Plant growth shall be considered as an increase in plant volume and/or mass with or without the formation of new structures such as organs, tissues, cells or cell organelles that grow in the presence of sunlight.
Thus, plant will grow best in sunlight. So, the correct option is (D).

What are genes?A gene is the fundamental structural and operational component of hereditary material. DNA is the material that constitutes genes. Some genes' sole purpose is to provide instructions for making larger molecules known as proteins. However, many genes do not contain the coding necessary to produce proteins. Genes in humans can be as small as a few hundred DNA bases or as large as more than 2 million DNA bases.

approach are they most likely to try?
Interrupt some stage of the cell cycle, such as the formation of the spindle that separates chromatids.
Develop strong dyes that will be able to color the chromosomes for good visualization.
Provide dangerous levels of radiation to irradiate the
cancer cells in a human being.
Starve the cancer cells by starving the patients, thereby reducing chances of cell division.
Answer:
c
Explanation:
Chemotherapy i.e. use of drugs to destroy the cancer cells by inhibiting their growth and division. Therefore, option (A) of interrupting stages in cell cycle is correct.
What do you understand by chemotherapy?
Chemotherapy is a medication that employs strong chemicals to destroy rapidly developing cells in your body. Chemotherapy is most commonly used to treat cancer because cancer cells grow and proliferate significantly faster than the rest of the body's cells. There are several chemotherapy medicines available.
Taxol (Paclitaxel) and other drugs that poison microtubules and impede the mitotic spindle have been used extremely efficiently in chemotherapy. This prevents cancer cells from proliferating and kills them.
Therefore, pharmaceutical researchers uses drugs to learn cancer treatment. Option (A) is correct.
