In this exercise, it is necessary to know the systems that our bodies have and complete the sheet that will correspond to these answers:
1- Digestive
2- Urinary
3- Respiratory
4- Skeletal
5- Muscular
6- Integumentary
7- Cardiovascular
8- Endocrine
9- Nervous
10- Reproductive
So looking in more detail, the number one corresponds to the digestive system because it is the digestive process that starts in the mouth. The second is related to the urinary system, which is responsible for the filtration and elimination of excess water. The respiratory system corresponds to the third option, which is the gas exchange that occurs in the pulmonary alveoli.
The numbers 4, 5, and 6 are very important systems for the support of the human body, being respectively the skeleton system, the muscular system, and the integumentary system. The first system is responsible for support while the second is better known for locomotion and finally the third is known for covering the human body by the dermis.
The cardiovascular system is responsible for getting the blood transported throughout the body and pumped by the heart, so this system is related to number 7. Then the endocrine system is responsible for the hormones and how these hormones acted in the body and are number 8.
The number 9 corresponds to one of the most complex and principal systems, the nervous system, which has neurons as its cells and transmits the nervous impulse in response.
The last treated system is the reproductive system, known for its reproductive gametes, and its most important role is to maintain the reproduction of the species.

Answer:
Liquid helium
Explanation:
Liquid helium is known to be the coldest element in the world.
It has a ridiculous boiling point of -452 degrees
It is considered the only element on earth that does not freeze to become solid. normally, it is usually in a form of cryogenic fluid or superfluid.
Hence, the coldest element is known as LIQUID HELIUM
Explanation:
The number of electron density regions that encircle an atom is calculated by the steric number, which also defines the hybridisation of the central atom. In that scenario, there are six hybridised orbitals in the central atom, leading to a hybridization.

Answer:
No
Explanation:
A single property is not conclusive for identifying a substance. For example, conductivity. Copper, aluminum, and lead all conduct electricity, yet they have different atomic number, electronegativity, and physical properties, thus their shared property of conducting electricity is not enough to correctly identify each substance.
