During photosynthesis, sunlight shining on a plant is absorbed. The energy transformation occurs during this process is thermal energy to chemical energy.
Photosynthesis is a process by which the plants make their food. The process takes sunlight, water, and chlorophyll into food.
Thus, the correct option is A.thermal energy to chemical energy.

An even distribution of electron density across the molecule, which means that the molecule has no distinct positive or negative ends. This lack of polarity makes the molecule symmetrical, and the forces of attraction between individual molecules are weak. Consequently, nonpolar molecules tend to have low boiling points and are generally insoluble in polar solvents.
When two oxygen atoms come together to form an oxygen molecule (O2), they share electrons to form a covalent bond. In this bond, each oxygen atom shares two electrons with the other oxygen atom, creating a stable molecule.
While it is true that the oxygen atoms in O2 molecule are electronegative and pull on the shared electrons in opposite directions, the two oxygen atoms are identical in terms of their electronegativity. This means that they pull on the electrons with equal strength, resulting in a balanced distribution of charge across the molecule. As a result, the molecule becomes nonpolar.

B. Jupiter
C. Mars
D. Neptune
Answer: Jupiter is believed to have prevented the asteroids in the asteroid belt from forming a planet.
The water molecules slow down, stronger attractions form between them, and the molecules stop flowing around.
The water molecules speed up, attractions between them become weaker, and the molecules spread out.
The water molecules speed up, new bonds are formed, and the new molecules are pulled closer together.
Answer:
The water molecules slow down, stronger attractions form between them, and the molecules stop flowing around.
Explanation:
imagine how the solids (so ice) are structured: atoms are very close to each other and vibrate on the spot.
The answer would be:
Pure substance: specifically a compound
Pure substances can be categorized into compounds and elements. A compound is a pure substance that cannot be broken down physically, but it can be broken down through chemical means. It is this property that differentiates it from mixtures. Mixtures can be broken down by physical and/or chemical means.
Elements on the other hand, cannot be broken down at all because it is in its simplest form and is also considered as a pure substance.
Answer:
Pure substance
Explanation:
Matter can be broadly classified into two categories: Pure substances and Mixtures (homogenous and heterogenous mixtures).
The simplest form of a pure substance is an element which cannot be broken down any further. When two or more elements combine, they form a compound which is also a pure substance. Thus, pure substances are systems that are either composed of a single type of element or a single type of molecule.
For example salt (NaCl) is a compound which is composed of elements: sodium (Na) and chlorine (Cl). These elements (in fact ions, Na+ and Cl-) are held together by a chemical bond. Thus, a pure substance like NaCl can be broken down into its elements through chemical means.
The unknown substance in the given question can therefore be classified as a pure substance
