Answer:

more reliable. The more results the better results you get.

Explanation:

Answer:

more reliable results

Explanation:

hey there,

< More data is more reliable results as you can see even more about the experiment you are doing! If you only know one other scientist that had done the experiment and it worked for him, then that's not enough data, but if you have thousands of scientists that were able to do the experiment correctly, you will have a more reliable and correct result since now you have more data. >

Hope this helped! Feel free to ask anything else.

Explanation:

The chemical equation for respiration process is:

[tex]C_{6}H_{12} O_{6}[/tex] + [tex]6O_{2}[/tex] → [tex]6CO_{2}[/tex] + [tex]6H_{2} O[/tex] + ATP↑

Energy is released during the biochemical process in the organism's cells in form of ATP. Byproducts of the reaction are carbon dioxide and water molecules.

When a solid substance is dissolved in a liquid such as water, the intermolecular forces of attraction between the molecules in the solid substance are overcome and they exist as ions in the solution. Hence the answer is 2.

The correct option is 2.

When a solid substance is dissolved in a liquid such as water, the intermolecular forces of attraction between the molecules in the solid substance are overcome and they exist as ions in the solution.

Dissolution is the process in which a substance forms a solution. Dissolution testing measures the extent and rate of solution formation from a dosage form, such as a tablet, capsule, ointment, etc. The dissolution of a drug is important for its bioavailability and therapeutic effectiveness.

Stirring sugar into water is an example of dissolving. The sugar is the solute, while the water is the solvent. Dissolving salt in water is an example of the dissolution of an ionic compound.

Answer:

contain hereditary information

break down food into energy

Explanation:

Hereditary information is contained in genes and genes are found inside the cell. This implies that the cell contains hereditary information of organisms. This hereditary information is passed on during cell division from parent to daughter cells.

Metabolism occurs in the cells. The cells use oxygen to break down food materials to produce energy.

Answer:

Explanation:

The only option that is not an effect of increasing carbon dioxide levels in the atmosphere is cutting down forests.

An increasing level of carbon dioxide in the atmosphere causes ocean acidification due to the dissolution of the gas in the oceans. Carbon dioxide also causes global warming - an increase in the average global temperature due to the heat (from the sun) absorbing ability of the gas.

Global warming causes an increase in the level of seas and oceans as a result of the melting of glaciers and polar ice caps. The rise in sea levels causes flooding with associated loss of habitats and biodiversity.

The increase in global temperature also means that cold-related deaths will reduce.

Correct option: b

Answer:

C. cutting down forests

Answer:

Volume of the cube is 2*2*2 = 8cm^3.

Divide the weight (40g) over the volume (8cm^3).

Density is 5g/cm^3. Definitely not gold.

Explanation:

Yes, the given golden-colored cube is gold .The density of gold is 32 gm/cm³ and we must buy it.

Density is a  mass of a unit volume of a material substance.

The formula for density is d = M/V, where d is density, M is mass, and V is volume.

Density is commonly expressed in units of grams per cubic centimetre.

To calculate density-

given

mass=40gm

side of cube =2cm

therefore, volume=(side)³

=8cm³

density=?

density=mass/volume

density=40/8

density=5 gm/cm³

The handed golden-colored cube is gold with its density 5gm/cm³ and  hence we must buy it.

Answer: D. Processing

Explanation: 100% on topic test also its in my e notes.

Craik and Lockhart has proposed theory of memory processing. Thus, option D is correct.

Craik and Lockhart proposed the theory for the processing of the level of memory. The memory in humans can be sensory memory, working memory, and long-term memory.

The long term memories have been stored in the deeper cells and the increased or strong stimulation of the processing results in the stronger retention of the memories. Thus, option D is correct.

Answer:

The ratio of the particles that make it up is fixed

Explanation:

Answer:

The researcher should measure the difference in the amount of product at the end of the reaction.

Explanation:

Enzymes are defined as the protiens that are responsible for increasing the rate of reaction.

With the increase in temperature, the enzyme activity increases and so the rate of reaction increases. It means at lower temperature the rate of reaction decreases and the amount of product also decreases.

So, to determine the effectiveness of an enzyme at various temperatures, the difference in the amount of the product at the end of reaction should be measured.

Hence, the correct answer is "D".

Answer:

Melting Point.

Explanation:

In testing of a sample has impurities, we have to check the samples’s melting or boiling points or we a separation technique called chromatography.

Now, CaBr_2 which is calcium bromide is a White Hygroscopic Powder. Therefore it is a solid.

Now, a pure solid will always have a fixed melting point which means that it will melt completely at only one temperature.

However, if there are impurities, the melting point of a substance is affected in two ways:

-It's lower than than the fixed melting point

- It would melt at a range of different temperatures as opposed to a fixed temperature for the pure form.

Therefore, a quantity that can be used to determine whether the sample was pure will be melting point.

Answer:

Explanation:

Given :

Mass of oxygen containing carbon monoxide (CO) is 2.666 gram .

To Find :

How many grams of carbon (C) would be present in carbon monoxide (CO) that contains 2.666 grams of oxygen (O) .

Solution :

By law of constant composition , a given chemical compound always contains its component elements in fixed ratio (by mass) and does not depend on its source and method of preparation.

So , volume of solution does not matter .

Moles of oxygen ,

Now , molecule of CO contains 1 mole of C .

So , moles of C is also 0.167 mole .

Mass of carbon ,

Therefore , mass of carbon is 2 grams .

Hence , this is the required solution .
