Explain the role of valence electrons and how they relate to the periodic table of elements?


Plz this i really need to finish this.

Answers

Answer 1

Explanation:

The valence electrons determine the group the elements belong in the periodic table. For example, the element sodium, Na, has a valence electron of one and so it belongs to Group 1 in the periodic table. Another example is Aluminium, Al, which has a valence electron of three and therefore it belongs to Group 3 in the periodic table.

the half-cooked egg yolk oozes out only when it is still hot.In the same manner,the magma on the mantle also rises because of high temperature, in the mantle, or the crust?​

Answers

Answer:

the mantle

Explanation:

The correct answer would be the mantle.

The magma is a hot, molten fluid or semi-fluid located beneath the earth's surface and capable of finding its way through fissures into the surface of the earth in a process known as a volcanic eruption.

From the innermost to the outermost, the earth layer consists of the inner core, the core, the mantle, and the crust. More specifically, the magma is known to originate from the lower part of the crust and the upper part of the mantle. The mantle's temperature is high and forms a layer of partially molten rock.

Why is it difficult for your body to return blood from your feet when you sit for too long?. Single choice. a. Blood has to travel a greater distance. B. Skeletal muscles are not squeezing the veins. c. Gravity makes the blood flow backward. d. The heart does not beat fast enough at rest.

Answers

Answer: Option C.

Gravity makes the blood flow backward

Explanation:

it difficult for your body to return blood from your feet when you sit for too long because gravity makes blood flow backward and this is because when you sit for long , it weakens the keg muscles because it is necessary for body movement so that blood will circulate or flow well. When the keg muscles becomes weak, it will slow blood flow in the leg and the force of gravity acting will make the blood flow backward and thus can cause a blood clot.

Carrying the genetic message from DNA to the ribosomes

The function of mRNA in the diagram given above is carrying the genetic message from DNA to the ribosomes.

What is the function of mRNA?

The main function of mRNA has to work as the immedieter between the protein and DNA which has been  utilised by the ribosome for the process of the direct synthesis of protein, and the function of tRNA has to carry the accurate amino acid to the proteins synthesis site which takes place in ribosome.

RNA has backbone and it has to made up of phosphate group which has been arranged in alternating form and the sugar known as ribose other than the deoxyribose  present in DNA. There are four bases found in RNA and these are adenine, uracil, guanine, and cytosine.

Liquid consist of small range of order and the reason behind this is intermolecular attractive force which is very strong and due to this reason molecules are packed together tightly.

Therefore, The function of mRNA in the diagram given above is carrying the genetic message from DNA to the ribosomes.
