The s orbital can hold up to two electrons while the p orbital can hold up to six electrons.
An atoms satisfying the octet rule means that this atom has eight electrons in its outermost energy level (which is the maximum number of electrons that can be found in a single level and makes the atom stable).
For this to happen, two electrons must occupy the s orbital and 6 electrons must occupy the p orbital. This makes a total of eight electrons.
Therefore, the right choice is:
<span>d) both full s orbital and full p orbital</span>
Answer:
The correct answer will be-
1. Nucleosomes
2. Chromatin
3. Sister chroamtid
4. Centromere
Explanation:
The DNA is a very long molecule which if has to be passed on to the daughter cell as it is will cause problems. So, to reduce problems a cell form tightly packed structure of DNA so that they can be passed easily to the daughter cell.
The packaging of DNA begins with the wrapping of the DNA around histone proteins which forms the 11 nm basic structural units called nucleosomes. The nucleosomes start condensing each other and form 30 nm structure chromatin fibres.
The chromatin fibres undergo replication during S phase which produces an exact copy of the chromatin called sister chromatids bound to each other at a central point called centromere which helps the separation of the chromatids during M phase.
Lysosomes are organelles that float on the cytoplasm and their main function is to secrete waste out of the cell and digest.
Lysosomes are found in eukaryotic cells and yes, they are present in plant cells.
Hope it helped.

Answer: Incorrectly paired nucleotides that still remain following mismatch repair become permanent mutations after the next cell division.
Explanation: If they replicated than the entire thing would copy that and would be permanent.
Explanation:
Primary succession occurs when a habitat that has completely destroyed reheals from complete scratch
On the other hand, secondary succession occurs when only a portion of the original ecosystem survives and is rebuilt from that
