Answer:
Basis and basic are two different words.
In English, Basis is used as a noun while basic is used as an adjective. Basis term refers as the base or starting point of any discussion.
For example: Bread is a basic ingredient of cake.
On the basis of Mendel's hypothesis.
In chemistry, Basis set is used as a set of functions that represent the electronic wave function in the density-functional theory which forms an algebraic equations that can be easily implemented on a computer.
While Basic term is used for substances that can accept a hydrogen ion (H+) from another substance and have pH above 7. such as sodium.
So, It is not important that both the terms, basis and basic change their English meaning if used in chemistry, they both can be used with English meaning in chemistry as well. Bases and basic, both the terms can be used as either English or Chemistry without affecting the meaning.
Density is measured by
"<span>
the mass per volume of an object" or option B. Mass is measured by the amount of weight in a object. (option A) The amount of weight is measured by the size of the object, (option C) and the size of the object is often measured by the hardness of an object. (option D)

Photosystems are the protein molecules that are optimized to harvest light. There are two types of photosystems: photosystem I (PSI) and photosystem II (PSII).
PSI is called P700 and PSII is called P680. It is called P700 because it absorbs the light at around 700 nm wavelength. P680 because it absorbs the light at around 680 nm wavelength.
In non-cyclic photophosphorylation, the photons of light is first transferred to P680, boosting an electron to a high energy level. The high-energy electron is passed to an acceptor molecule and replaced with an electron from water. This splitting of water releases the O2 we breathe.
In cyclic photophosphorylation, the light of wavelength 700 nm is absorbed by P700 and the electrons are the passes to the acceptor molecule by several carriers.
Answer:
The correct answer is , Weak bonds are transient and easily reversible.
Explanation:
Molecules or atom that associate to produce a weak bond can interact, and then separate .this is evident in hydrogen bond and vanderwaal force where the combined effect can produce emergent properties.
Example; the hydrogen bonds present in water molecule; when the bonds are broken using heat, the molecules are separated or released in form of vapor, this same molecule can combine again by condensation to produce liquid. showing clearly how transient and reversible the bonds between them is.
