Answer is: adenosine triphosphate.
ATP is made of three components: the triphosphate (P), the sugar ribose and a nitrogenous base (adenine).
ATP is short for adenosine triphosphate
Adenosine triphosphate converts to either the adenosine diphosphate (ADP) or adenosine monophosphate (AMP), in this process energy is released.
The correct answer is A- Adenosine Triphosphate

The ones that are able to survive pass on their genes to the next generation. Bye doing that they pass on certain traits to the next generation causing them to inherit those traits and develop new ones and that prosses repeats for thousands and millions of years and that's how they are able to evolve.
Answer:
The number of protons of the Pb is 82.
The number of electrons of the Pb²⁺ is 80.
Explanation:
Each chemical element is characterized by the number of protons in its nucleus, which is called the atomic number Z.
The atomic number is used to classify the elements within the periodic table of the elements. In it, you can read in the upper left. In this case, the lead Pb has an atomic number of 82. This indicates that the number of protons of the Pb²⁺ is 82.
In every electrically neutral atom the number of protons in the nucleus is equal to the number of electrons in their orbitals. But in this case it is a cation, that is, it is a positively charged ion. A cation is formed when electrons are lost (which have a negative charge), thus acquiring the positive charge ion. In this case then, Pb²⁺ indicates that the cation has a +2 charge. So this means that 2 electrons have been lost. So, if it were electrically neutral, the lead Pb would have 82 electrons, but with the loss of two of its electrons, the number of electrons of the Pb²⁺ is 80.
There are 82 protons and 80 electrons in one Pb²⁺ ion. Lead (Pb) has an atomic number of 82.
The atomic number of an element represents the number of protons in its nucleus. Since lead (Pb) has an atomic number of 82, it means that a neutral lead atom has 82 protons.
When the Pb²⁺ ion is formed, it means that the atom has lost two electrons. The +2 charge indicates that the atom now has two more protons than electrons. Since electrons have a negative charge, losing two of them results in a net positive charge on the ion.
Since a neutral lead atom has 82 electrons, subtracting two electrons from it gives us 80 electrons in the Pb²⁺ ion. However, the number of protons remains the same at 82. The loss of electrons creates a positive charge, and the number of protons determines the element's identity.
In summary, the Pb²⁺ ion has 82 protons and 80 electrons. The 2+ charge indicates the loss of two electrons, resulting in a net positive charge on the ion.

Calcium is very reactive, has properties similar to magnesium, and is in the same period as bromine.
Properties are defined as the qualities that help us distinguish one material from another.
There are basically two types of properties.
Reactive is defined as the catalyst for a chemical process, either on its own or in combination with other materials.
It can also be defined as the propensity of a substance to undergo chemical reaction and release energy, either by itself or in conjunction with other materials.
Thus, calcium is very reactive, has properties similar to magnesium, and is in the same period as bromine.

B) The attractive forces are stronger in a liquid
C) The attractive forces are stronger in a solid
D)The attractive forces of a solid allow the particle to move freely while the liquid molecules vibrate around a fixed point
Answer:
Option-C (The attractive forces are stronger in a solid)
Explanation:
The substance either exist as a Solid or Liquid depends upon on the following two factors;
ii) Kinetic Energy:
Greater the K.E of particles, greater will be the distance between the particles of a substance. In Liquids the K.E of particles is greater than the K.E of particles in Solid. Hence, the Liquid Particles separated by greater distance as compared to particles of Solids.
ii) Attractive Intermolecular Forces:
Greater the Attractive Intermolecular Forces between the particles of a substance, smaller will be the distance between the particles. As the distance between the particles in Solid state of substance are very small as compared to that of Liquids hence, it can be concluded that the Attractive Intermolecular Forces in Solids are stronger than Liquids.
