Answer:
C. Phosphorus (P)
Explanation:
Given;
Electron configuration 
Firstly we have to find out the number of shell of given element. For this we have to add number of electron of each shell.
Here counting goes to 3 that means element have three shells. Now we find out number of electrons in each shell.
First shell of an element is K and it has only one sub shell that is 1s. In this element 1s contains only 2 electrons.
For 2nd shell that is L has two sub shell 2s and 2p, for this element 2s contains 2 electrons and 2p contains 6 electrons. That means total number of electrons for L shell is 8.
Now for 3rd shell that is M has two sub shell 3s and 3p, for this element 3s contains 2 electrons and 3p contains 3 electrons. That means total number of electrons for M shell is 5.
Now total number of electrons for the element is the sum of number of electrons in each shell.
Total number of electrons = 2+8+5=15
And we know the number of electrons of any neutral element is equal to the number of protons and number of protons gives us atomic number of the element.
So the atomic number of given element is 15 that is of Phosphorus.
Answer:
The transcription of DNA into a complementary strand of mRNA does not take place in translation.
Explanation:
Answer:
A
Explanation:
Increase enzyme concentration so more enzymes can react with carbon dioxide to form bicarbonate. D would make the reaction slower, C does not relate to the question and B is the product so would not help increase the rate of the reaction, only A
1) The limbs of a bat and the forelimbs of a bird is an example of Analogous structures
2) The arm of a human and the arm of chimpazee is an example of Homologous structures
3) Frogs and salamanders is an example of Homologous structures
<span>Homologous structures, are organs or systems of different living beings
that have a common origin, but different adaptations. For example, the
extremities of a dog and a dolphin, are homologous, have similar bones, only
that some adapted to the race and others to swimming. On the other hand,
analogous structures are organs or systems of different living beings that do
not have a close origin in common, but are adapted to the same environment, for
example, fins of fish and dolphin fins, the function is the same, the origin is
different; or the wings of birds and the wings of insects.</span>
