What are the similarities and differences between electrons and protrons

1 answer:

3 0

The difference between protons and neutrons are that one has a positive charge and one has a neutral charge. The similarities between the two is that they both make up an atom. The Electrons in an atom are in orbit of the cell inside the Electron cloud and is kept in the cloud by electromagnetic force.

Process where air in the lower atmosphere flows together resulting in mid-afternoon thunderstorms.

emmainna [20.7K]

Answer:

Small scale convergence

Explanation:

This term in meteorology occurs in a convergence zone; a region in the atmosphere where two air flows meet and interact, usually resulting in major weather conditions. A Small-scale convergence will produce situations ranging from isolated cumulus clouds to large areas of thunderstorms.

If an organism didn't have DNA, it would be missing which sign of life? A. one or more cells B. information system C. response t

Zepler [3.9K]

Answer:

The correct answer would be - option B. information system.

Explanation:

DNA is the unit of heredity as it contains the genetic code of an organism which is carried all the genetic information and transfer from the parent cell to the daughter cell. It also carries the information required for making all essential proteins in an organism.

So, if an organism did not have DNA, it would be missing the information system which is also responsible for the cell division other than given information.

Explain how atomic number relates to the number of particles in an atoms nucleus

SIZIF [17.4K]

Answer:

the atomic number is relates to the number of particles in an atoms nucleus because is the number of protons.

Explanation:

the nucleus of the atoms has neutrons and protons in its composition. The protons which is the positive charges of the atoms is the same quantity with the atomic number.

A) In the Dunker population, the frequency of IB allele is 0.3 and the frequency of i allele is 0.4. In the general population, the frequency of IB allele is 0.1 and the frequency of i allele is 0.5.

If:
$I^{A}$ - the frequency of IA allele
 $I^{B}$ - the frequency of IB allele
 $i$ - the frequency of i allele

Then:
 $I^{A} I^{A}$ + $I^{A} i$ - the frequency of individuals with A blood type
 $I^{B} I^{B}$ + $I^{B} i$ - the frequency of individuals with B blood type
 $ii$ - the frequency of individuals with O blood type

Let's first take a look on the Dunker population:
$I^{A} = 0.3$
$ii=0.16
$

Since there is only one possible genotype for O individuals - ii - the frequency of the allele i is square root of the frequency of O individuals:
 $i= \sqrt{ii}$
⇒ $i = \sqrt{0.16}$
⇒ $i=0.4$

Now, we have the frequencies of two alleles ( $I^{A}$ and $i$ ). To calculate the frequency of $I^{B}$ allele, we will use the formula:
 $I^{A} + I^{B} + i = 1$
⇒ $I^{B} = 1- I^{A} - i$
⇒ $I^{B} = 1-0.3-0.4$
⇒ $I^{B} = 0.3$

Now, in the general population:
$I^{A} = 0.4$
$ii=0.25$

Similarly to the work for the Dunker population:
 $i= \sqrt{ii}$
⇒ $i = \sqrt{0.25}$
⇒ $i=0.5$

$I^{A} + I^{B} + i = 1$
⇒ $I^{B} = 1- I^{A} - i$
⇒ $I^{B} = 1-0.4-0.5$
⇒ $I^{B} = 0.1$


b) A founder effect is a result of geographical separation of a few individuals from the original population. Those founding individuals will form a new population. The Dunker population was not only geographically separated, but also genetically. The group interbreeding was present resulting in increasing those allele frequencies that were the most common in the founding population. In this case, the most individuals from the founding population had B blood type.
