Hydrophilic means ____ love of water fear of water a water pressure mechanical system related to dams
kow [346]

Answer:

love of water

Explanation:

HYDROPHILIC is a term used for substances that are WATER-LOVING in nature. As the name implies, hydro-meaning water and philia- meaning love, it means the love of water. Substances that are hydrophilic tend to be attracted towards water molecules and are readily dissolved by it. For example, sugar molecules are hydrophilic, hence, attract and dissolve in water.

On the other hand, hydrophobic means water-fearing i.e substances under this category repel water. Examples are some fat molecules.

(a) What cell structures best reveal evolutionary unity?
xeze [42]

Answer:

The correct answer will be-

1. Evolutionary unity-  DNA

2. specialized cellular modifications- plant cells have chloroplasts and large central vacuole.

Explanation:

<u>Case I </u>

Evolutionary unity is a concept which explains that all the organisms possess some common structure or universal structure or molecules.

The best characterized evolutionary molecule is DNA molecule which took the role of genetic material in past and is passed on to the daughter cells and still is made up of the same components which are a five-carbon sugar, four types of nitrogenous bases and a phosphate group. This DNA molecule is present in almost every organism except for a few viruses.

<u>Case II </u>

The specialization of the cellular components depends on the function a cell has to perform which became established in the population. The plant cells depended on the sunlight to prepare food for themselves which was done by the chloroplast organelle which is absent in the animal kingdom.
