Explanation:

The density of a substance can be found by using the formula

[tex]density = \frac{mass}{volume} \\[/tex]

From the question

mass = 992 g

volume = 1000 mL

We have

[tex]density = \frac{992}{1000} \\ = 0.992[/tex]

We have the final answer as

Answer:

A physical property is a characteristic of matter that is not associated with a change in its chemical composition. Familiar examples of physical properties include density, color, hardness, melting and boiling points, and electrical conductivity.

Explanation:

Elements in the same group have the same number of outermost electrons.

Electronic structure refers to the arrangement of electrons in the atom. We know that elements in the same group have the same number of outermost electrons.

However, as we come down the group, the inner shells of the elements in group 14 become bigger and the outermost shells are now found at higher energy levels such as n=4 or 5.

B) mitochondria

Explanation:

Dietary protein will not be digested if Hcl were not being produced in sufficient quantities.

In the stomach, there are some glands found on the stomach lining that helps to release hydrochloric acid (HCl). Their major role is to dissolve food and produce an acidic medium.

The acidic media promotes and improves the conversion of pepsinogen to pepsin. Pepsin acts as an enzyme that supports protein digestion.

Protein digestion requires a pH of around 1.8 which can be achieved by the secretion of HCl.

As a result, if HCI is not released in the stomach in sufficient quantities, pepsin will not be activated and it would have a detrimental impact on protein digestion.

Therefore, we can conclude that dietary protein will not be digested if Hcl were not being produced in sufficient quantities.

Answer: I think they will be compared by dividing 10 from 100 which equals 10 which will be your volume of the boiling point

Explanation:

Please look at others answer I am not 100% sure if this is correct.

The two factors which must be held constant for density to be a constant ratio are: Mass and Volume

As we know, the density of a material is simply defined as the ratio of mass to volume.

Consequently, To obtain a constant ratio for density, the mass and volume of the material in discuss must be kept constant.

Answer:

Plant cells have a cell wall and chloroplasts; animal cells do not have either of these structures.

Explanation:

A major difference between a plant cell and an animal cell is presence of chloroplasts in plant cells. Another key difference between plant and animal cells is the presence of a cell wall in plant cells. Both structures are absent in an animal cells.

The cell wall surrounds the plasma membrane of plant cells. This helps to provide the required tensile strength and protection against mechanical and osmotic stress.

Cell walls also help plants to maintain shape and rigidity.

Answer:

1) Plant cells have a cell wall to strengthen the cell

2) Chloroplasts are the site of photosynthesis (turning light energy in sugar) so there would eb a lot more in the leaves that get sunlight than the roots which are underground and receive no sunlight

3) Mitochondria and nucleus

4) No. Some microorganisms are useful to humans, such as the bacteria that create yoghurt, or fungi such as penicillin which are antibiotics, which help us fight bacterial infections

A thermos slows down the process of heat transfer as it minimizes the process of conduction and convection.

Conduction is defined as a process as a means of which heat is transferred from the hotter end of the body to it's cooler end.Heat flows spontaneously from a body which is hot to a body which is cold.

In the process of conduction,heat flow is within the body and through itself.In solids the conduction of heat is due to the vibrations and collisions of molecules while in liquids and gases it is due to the random motion of the molecules ,

When conduction takes place, heat is usually transferred from one molecule to another as they are in direct contact with each other.There are 2 types of conduction:1) steady state conduction 2) transient conduction.According to the type of energy conduction is of three types:

1) heat conduction

2) electrical conduction

3)sound conduction

Answer:

a change in the level of consumer income

Explanation:

Selectivity is relatively easy to alter, with mobile phase composition and stationary phase being the primary means of adjustment. The hydrophobicity, polarity and nature of the chosen stationary phase all play a crucial role in analyte interaction and directly affect the selectivity of a separation.

In chromatography, it is important to select a good stationary phase so as to ensure proper separation of components.

Chromatography is a separation technique which is generally used for separating substances based on their solubilities. The technique makes use of two phases the mobile phase and the stationary phase.

The components are separated from each other based on their solubility in the mobile phase. Component which is least soluble does not travel along the mobile phase while component which is highly soluble travels with the mobile phase.

The difference in the solubility of the components is measured with the reference to the solvent front and is expressed in terms of Rf value.Chromatography finds application in forensics, separation of organic compounds,etc.
