Select choices that result from hydrogen bonding.

8 0

A hydrogen bond is an intermolecular force (IMF) that forms a special type of dipole-dipole attraction when a hydrogen atom bonded to a strongly electronegative atom exists in the vicinity of another electronegative atom with a lone pair of electrons. Intermolecular forces (IMFs) occur between molecules. Other examples include ordinary dipole-dipole interactions and dispersion forces. Hydrogen bonds are are generally stronger than ordinary dipole-dipole and dispersion forces, but weaker than true covalent and ionic bonds.

In a nutshell, a chemical change produces a new substance, while a physical change does not. A material may change shapes or forms while undergoing a physical change, but no chemical reactions occur and no new compounds are produced. And for an explanation on how to see the difference Look for an indication that a chemical change occurred. Chemical reactions release or absorb heat or other energy or may produce a gas, odor, color or sound. If you don't see any of these indications, a physical change likely occurred. Be aware a physical change may produce a dramatic change in the appearance of a substance. This doesn't mean a chemical reaction occurred.

Describe why the amount of light available to the Chlorella culture might affect the growth dynamics of the alga.

-Dominant- [34]

Answer:

See the answer below

Explanation:

The amount of light available to Chlorella culture might affect the growth dynamics of the alga because the light is an important factor necessary for the synthesis of carbohydrates and other important molecules in the body of the organism.

The process of synthesizing carbohydrates is termed photosynthesis and during this process, the energy of light is used to excite the photosystem of the chlorophyll of the organism, leading to the release of electrons whose energy is used to synthesize an energy molecule that is utilized in the latter part of the photosynthetic process. The entire process of photosynthesis can be summarised as an equation below:

$6CO_2 + 6H_2O + light --> C_6H_1_2O_6 + 6O_2$

The manufactured carbohydrates act as food for the organism and are broken down during respiration to release energy necessary to drive metabolic processes that bring about growth and development.

Hence, the amount of light is an important factor that might affect the growth dynamics of all green plants, including the Chlorella.
