Answer:
The wall of the arteries belongs to the circulatory system. The fat deposit belongs to the adipose connective tissue.
Explanation:
The arterial system is the high pressure portion of the circulatory system. Blood pressure ranges from the maximum pressure during cardiac contraction, called systolic pressure, to the minimum pressure, or diastolic pressure, between contractions when the heart rests between cycles. This variation in pressure in the arteries produces a pulse that is observable in any artery, and is an indicator of cardiac activity. The wall of the arteries is thick, formed of elastic muscle tissue.
Adipose tissue is a type of connective tissue with special properties. It has many adipocytes, specialized cells, which have the main function of energy reserve, through a fat deposit, for the body, among others. Fat is deposited in fat cells also called adipocytes.
The arterial wall and fatty deposit belong to the cardiovascular system.
The arterial wall and the fatty deposit belong to the cardiovascular system in the human body.

(2) 2-chloropropane (4) 2-pentene
Answer: N (atomic number 7)
Explanation:
1) Due the electron distribution of each, taking into account Hund's rule to deal with pairing of electrons.
2) Hund's rule: each subshell orbital is occupied with single electrons of parallel spin before double occupation occurs.
That is, before any one orbital is doubly occupied, every orbital in a subshell is singly occupied with one electron, and all the electrons in singly occupied orbitals have the same spin, which means that they are unpaired.
3) Distributions:
a) C (atomic number 6) ⇒ 6 electrons:
⇒ 1s² 2s² 2p² ⇒ 1s² 2s² 2p ↑ ↑ : as per Hund's rule the two electrons on 2p are unpaired.
b) O (atomic number 8) ⇒ 8 electrons
⇒ 1s² 2s² 2p⁴ ⇒ 1s² 2s² 2p⇅ ↑ ↑: as per Hund's rule the two 2p electrons are unpaired
c) N (atomic number 7) ⇒ 7 electrons
1s² 2s² 2p³ ⇒ 1s² 2s² 2p↑ ↑ ↑: as per Hund's rule, the three 2p electrons are unpaired, so this is the answer to the question.
c) Be (atomic number 4) ⇒ 4 electrons
⇒ 1s² 2s² ⇒ none p electron.
Nitrogen has three unpaired electrons in its p orbital.
Among the given elements, nitrogen (atomic number 7) has three unpaired electrons in its p orbital.
In the electron configuration of nitrogen, it has a total of five electrons: 2 in the 1st energy level and 3 in the 2nd energy level. The p sublevel of the 2nd energy level contains three orbitals, each capable of holding 2 electrons. Therefore, the three unpaired electrons in nitrogen's p orbital are in three separate p orbitals in the 2nd energy level.
Carbon has two unpaired electrons in its p orbital, while oxygen has two unpaired electrons in its p orbital and two in its s orbital. Beryllium does not have any unpaired electrons in its p orbital.

The process melts an ore to separate useful metals from the rest of the elements in the ore is called smelting. The ore is heated beyond its melting point to extract the metal with the help of oxidizing agents such as air or reducing agents such as coke.
