Answer:

C. Biotechnology

Explanation:

In its broadest definition, biotechnology is the application of biological techniques and engineered organisms to make products or modify plants and animals to carry desired traits. This definition also extends to the use of various human cells and other body parts to produce desirable products.

They're made up of three main parts: protons, neutrons and electrons. Think of the protons and neutrons as together forming a “sun”, or nucleus, at the centre of the system. The electrons orbit this nucleus, like planets. If atoms are impossibly small, these subatomic particles are even more so.

Answer:

If you change everything at once, you may not know what caused the end result.

Explanation:

If you have Variable A (Salt), Variable B (Potassium), and the Control of Water, you might mix everything together, so you mix salt, potassium and water together. It is known that Potassium reacts very aggressively in water, but since you mixed everything together, you might think that salt+potassium+water goes boom, while it is actually potassium+water=boom.

Answer:

C. The mass of an electron is much less than the mass of a proton or

a neutron.

Explanation:

When we compare the mass of an electron to that of proton or neutron, the mass of an electron is much less than the mass of a proton or a neutron.

Electrons are negatively charged particles in an atom

Protons are positively charged particles

Neutrons do not carry any charges.

We can see that electrons have very small mass and this is why when calculating the mass of an atom, we use the sum of the number of protons and neutrons.

Answer: Matter takes up space and has mass

Explanation:

Literally the definition of mass

Answer:

i think false

Explanation:

Centre of mass is the point at which the distribution of mass is equal in all directions, and does not depend on gravitational field. Centre of gravity is the point at which the distribution of weight is equal in all directions, and does depend on gravitational field

Answer:

Its B. The atoms form a bond with a bond lenth of 75 pm

The % lithium by mass in a sample of pure lithium carbonate : 18.79%

Proust states the Comparative Law that compounds are formed from elements with the same Mass Comparison so that compounds have a fixed composition of elements

% Lithium (Li) in Li₂CO₃(lithium carbonate) will remain the same even if the mass amount of Li₂CO₃ changes

Ar of Li = 6.941 g/mol

MW of  Li₂CO₃  = 73.891 g/mol

[tex]\tt \%Li=\dfrac{2.Ar~Li}{MW~Li_2CO_3}\times 100\%\\\\\5Li=\dfrac{2\times 6.941}{73.891} \times 100\%=18.79\%[/tex]

Considering the reaction stoichiometry, from the balanced equation and reation stoichiometry, the number of moles of calcium  oxide produced is 1 mole.

Chemical reactions are characterized by the appearance of new substances from others. That is, they are processes in which the nature of the substances changes, that is, from some initial substances called reagents, totally different ones called products are obtained.

In this case, you know that the balanced reaction is:

CaCO₃ → CaO + CO₂

Stoichiometry establishes relationships between the molecules or elements that make up the reactants of a chemical equation with the products of said reaction. In other words, stoichiometry determines the ratios between reactants and products in a chemical reaction.

The stoichiometry of a chemical reaction is perfectly established by the chemical equation. In it, the formulas of reactants and products appear preceded by numbers (the stoichiometric coefficients) that indicate the proportions according to which the transformation occurs.

The stoichiometric coefficients of a chemical equation are due to the fact that the atoms present before the reaction must be the same after the reaction, even though the atoms will have been rearranged to produce new substances.

In this case, by reaction stoichiometry, the following amounts of moles of each compound participate in the reaction:

In summary, from the balanced equation and reation stoichiometry, the number of moles of calcium  oxide produced is 1 mole.

Answer:

different forms of genes for a single trait

Explanation:

There are three main forms  of genes  that can exist for a single trait and they are:

A dominant allele is a stronger version of a gene that shows up when at least one copy of it is present in an organism's genetic makeup. It hides the effects of the weaker gene. In a person with two different alleles, the one that is more powerful decides how the person looks or behaves.

Recessive allele: A recessive allele is only expressed when there are two of the same recessive alleles present. It is hidden by a strong gene. The recessive allele can only be seen when a person has two copies of it.

Co-dominant alleles: When co-dominant alleles are together, both are shown. In this situation, neither gene is stronger than the other, and both play a role in what an organism looks like. One example of co-dominance is the ABO blood type system. In this system, both the A and B alleles are of equal importance.

Its can affect the safety of products by, for example, if you put raw chicken in the oven and don't cook it for long enough, it can make you sick

Explanation:

The difference between the calculated and precise worth is referred to as an error or defect. For example, if the two machinists use the same device to detect measurement mistakes, it is not necessary that they obtain the same results. However, there will be a little difference between the two measurements, which is referred to as an error.

Volume displaced by jewelry, V = 278 - 200 = 78 ml

Also, 1 ml = 1 cm³

We know, by water displacement method the volume of water displaced by an object it equals to its own volume.

So, volume of jewelry, V = 78 ml = 78 cm³.

Also, weight of jewelry is , w = 122 gm.

Now, we know density is given by :

[tex]d=\dfrac{w}{V}\\\\d=\dfrac{122\ gm}{78\ cm^3}\\\\d=1.56\ gm/ cm^3[/tex]

Hence, this is the required solution.

Answer:

I think it's replacement because the B and D just swap places in the end equation

Answer:

that would be replacment

Explanation:

if you look at the formula the B and D are replaced with each other

synthesis is when it looks like A+B--> AB

decompositions looks like AB--> A+B

and oxydation is when the states of atoms are changed so it would include things like +1, -1 etc

Answer:

a = 6 m/s².

Explanation:

If we have the object with mass of 75 kg and force on it is 50 N then according to given statement its acceleration is 3m/s².

When we double the force on same object by keeping the mass constant then the acceleration will also double. It means force will be 100 N and acceleration will be 6 m/s².

But if we we increase the mass then acceleration goes to decrease.

So,

mass = 75 kg

F = 50 N

a = 3m/s²  then by double the amount of force,

mass = 75 g

F = 100 n

a = 6 m/s².

This is actually explain the newton second law. This law stated that the acceleration of object is depend upon its mass and force acting on it.

F=  m. a

a = F/m

Thus acceleration is directly proportional to the force and inversely  proportional to the mass.

Answer:

aluminum (solid)

Explanation:

Solids have fixed shape and volume at room temperature.

Matter is defined as any substance that has weight and occupies space. There are three main classes of matter;

  Solids are particles have strong attractive force between them. This confers a fixed shape and volume on them.

 Liquids are mostly fluids that takes up the shape of containers they occupy. The have intermediate strength of attractive forces.

 Gases have weak forces and do not have fixed shape or volume. They take up the shape of any container they are introduced into.
