Answer: Breaking covalent bonds in molecules results in the dissipating the energy of atoms held together in molecules.
Explanation: By way of introduction,
Covalent bonds are one of four types of chemical bonds. The other three are ionic bonds, metallic bonds and hydrogen bonds. Each bond type differs in the way atom share electrons. In covalent bonds, two atoms completely share one or more pairs of electrons. These bonds are quite strong.
Covalent bonds form between atoms when the total energy present in the newly formed molecule is lower than the energy present in each of the atoms alone. The lower energy when bonded results from the fact that atoms are more stable when their outer electron shells are full. Atoms can fill their outer shells by sharing electrons with other atoms though the formation of covalent bonds.
It is important to know that there is a symmetrical relationship between the amount of energy released during the formation of a covalent bond, the amount of energy needed to break the bond. Breaking covalent bonds requires energy, and covalent bond formation releases energy.
This energy is measured as heat using the units joules or calories or kilocalories.
The amount of energy released during molecule formation can be estimated by counting the number and types of bond in a molecule. For instances, a methane molecule has one carbon atom bound to four hydrogen atoms via four single carbon-hydrogen covalent bonds. Carbon-hydrogen bonds release 100 kcal/mole of energy when formed, so the total energy needed to break all the bonds in a methane molecule is 100 kcal x 4 or 400 kcal.
Protons are represented as the atomic number.
Answer:
photosynthesis, the process by which green plants and certain other organisms transform light energy into chemical energy. During photosynthesis in green plants, light energy is captured and used to convert water, carbon dioxide, and minerals into oxygen and energy-rich organic compounds.
The roots absorb water and minerals from the soil and anchor the plant in the ground. The stem supports the plant above ground, and carries the water and minerals to the leaves. The leaves collect energy from the Sun and make food for the plant, using an amazing process called photosynthesis.

Answer:
Zoonotic Diseases
Explanation:
Zoonotic Diseases: Disease Transmitted from Animals to Humans. A zoonosis (zoonotic disease or zoonoses -plural) is an infectious disease that is transmitted between species from animals to humans (or from humans to animals)
Example: Corona virus
Animals that commonly transit diseases : Rat, Bat
Planets like, mercury, venus earth: they are in the increasing order of there masses. however this chain breaks at mars.
Planets like, jupiter, saturn, uranus, neptune are arranged in decreasing order of there masses.
