Answer:
D: adhesion and cohesion
Explanation:
Water is a chemical liquid substance with unique properties that are responsible for the way it behaves. Cohesion and Adhesion are two of those properties responsible for the sticky nature of water molecules.
Cohesion is the property that makes a water molecule attracted to another water molecule by forming an hydrogen bond with one another, while adhesion is what makes a water molecule attracted to other substances aside water. These properties makes water sticky to itself (cohesive) and other chemical molecules (adhesive).
Answer:
Eukaryotic cells are cells that contain a nucleus and organelles, and are enclosed by a plasma membrane. Organisms that have eukaryotic cells include protozoa, fungi, plants and animals.

A prokaryotic cell is a simple, single-celled (unicellular) organism that lacks a nucleus, or any other membrane-bound organelle. We will shortly come to see that this is significantly different in eukaryotes. Prokaryotic DNA is found in the central part of the cell: a darkened region called the nucleoid (Figure 1).

Explanation:
<h2>Operational </h2>
Explanation:
The operational definition is the description of a specific process, or set of validation tests, accessible to more persons than the definer (i.e., said to be publicly accessible), where it can be repeatedly measured or tested
Operational definitions are also used to define system states or (nonspecific) physical objects by the description of a specific process of preparation which can be repeated
For example in the given example experimenter is using the case of hitting a punching bag to measure the level of aggression in someone
