<span>These are isotopes of carbon and they all contain 6 protons and 6 electrons but each contains a difference number of neutrons - 6, 7, and 8 respectively.

^ This is the answer because an isotope changes the atomic mass, NOT atomic number. That means that the neutrons are changed, not the protons. </span>

Answer: These are isotopes of carbon and they all contain 6 protons and 6 electrons but each contains a difference number of neutrons - 6, 7, and 8 respectively.

Explanation: Isotopes of an element have similar number of protons but different number of neutrons.

General representation of an element is given as: _Z^A\textrm{X} where,

Z represents Atomic number  (for neutral atom) = number of protons= no of electrons

A represents Mass number  = number of protons + number of neutrons

X represents the symbol of an element

Thus  _6^{12}\textrm{C} ,   _6^{13}\textrm{C} and  _6^{14}\textrm{X} all contain same number of protons i.e 6 but contain (12-6) =6, (13-6)=7 and (14-6)=8 neutrons respectively.

Vascular tissue is responsible for transporting water and nutrients in plants.The Vascular tissue consists of the Xylem and the Phloem. The main function of the Xylem is to transport water and minerals throughout all parts of the plant. Phloem on the other hand is responsible for transporting organic molecules that are larger in size. The vascular system, consisting on the Xylem and the Phloem runs from the roots of the plats through the branches and upto the leaves. It controls the total transportation of the water and nutrients.
<span>The long tubes that carry water and sugar from the leaves to the rest of the plat are known as phloem. The Xylem on the other hand carries water and small minerals from the root through the branches to the leaves for producing glucose and oxygen. The xylem and phloem are two most important parts of plants that are required for the survival of the plant. Water is mainly carried by the Xylem but some amount of water goes through the phloem for transporting the glucose that is manufactured. The process of photosynthesis is highly dependent on Xylem and Phloem.<span> </span></span>

How do you calculate the magnitude of a force?
Tamiku [17]
If the force equals, for instance, 100 Newtons then 0.866 × 100 = 86.6 Newtons. This is the magnitude of the resultant force vector on the object.
