Domains are larger than kingdoms and include more organisms as far as the classification of living organisms is concerned.

Domains

When it comes to classifying living organisms, the highest level of classification is the domain. Under each domain is where we have the kingdoms.

For example, the domain eukarya contain four kingdoms; plant, animal, fungi, and protozoa.

A particular graduated cylinder contains 24.0 mL Br2(liquid). The density of bromine at 25 degrees C is 3.12g/cm^3. Note that in
motikmotik

Answer:

2.82x10^{23}molecules

Explanation:

Hello.

In this case, given the volume (1cm³=1mL) and density of the bromine we are to firstly compute the mass since it will allow us to compute the representative particles:

\rho =\frac{m}{V}

m=\rho *V=3.12g/cm^3*24.0cm^3\\\\m=74.88gBr_2

Next, since the mass of one mole of diatomic bromine is 159.82 g (one bromine weights 78.91), we can next compute the moles in that sample:

n=74.88g*\frac{1mol}{159.82g} =0.469molBr_2

Finally, via the Avogadro's number we can compute the representative particles of bromine as follows:

particles=0.469mol*\frac{6.022x10^{23}molecules}{1mol}\\ \\2.82x10^{23}molecules

Best regards.

If a reaction has a very low activation energy, the products would be expected to form quickly at high temperatures. Select the
melamori03 [73]

Answer: Option (c) is the correct answer.

Explanation:

It is known that when Gibb's free energy, that is, \Delta G has a negative value then the reaction will be spontaneous and the formation of products is favored more rapidly.  

Activation energy is defined as the minimum amount of energy required to initiate a chemical reaction.

So, when reactants of a chemical reaction are unable to reach towards its activation energy then a catalyst is added to lower the activation energy barrier so the reaction can take place rapidly.

Since, the given reaction has low activation energy. Therefore, there is no need to add a catalyst.

And, when value of \Delta G is positive then the reaction is spontaneous in nature and formation of products is less favored.

Thus, we can conclude that for the given situation positive delta G is the reason that a reaction might form products very slowly, or not at all.

Explain why the Cell A (nerve cell) and Cell B (red blood cell) cannot switch jobs
SOVA2 [1]
Red blood cells carry a specific type of protein, called hemoglobin, which is able to bind oxygen and release it in other tissues. A nerve cell doesn't have this protein because it doesn't need to bind oxygen. Instead, the nerve cell uses other proteins that help it transmit signals to other cells.

That is copied from “gene expression” article

But all in all, the cells have different structures and different jobs. This means that they are produced for that one job and cannot be made to do another job that they aren’t specifically made for. As well the dna make up will produce these cells specifically and in different cells than the other.

Hopefully this helps some. Have a nice day!

How to calculate atomic mass?​
Alexus [3.1K]
To calculate the atomic mass of a single atom of an element, add up the mass of protons and neutrons. Example: Find the atomic mass of an isotope of carbon that has 7 neutrons. You can see from the periodic table that carbon has an atomic number of 6, which is its number of protons.

Hope this helps :)
