Answer:
Ligand-receptor interaction is the first interaction that triggers cell signalling.
Explanation:
Ligands are the hormones, drugs or neurotransmitters that specifically bind with receptors present in cell surface to initiate cell signalling. Ligand binding to the receptor is reversible. Binding of the ligand to the receptor can activate or inactivate receptor. Activation may lead to cell signalling pathways. Inside cells, there are secondary molecules which on activation starts a cascade of reactions. which in-turn regulate the function of the ligand molecule.

Considering the definition of volume, the volume of a cube with a side length of 3 centimeters is 3 cm³.
<h3>Volume</h3>
Volume is a measure of the space occupied by an object in three-dimensional space.
In other words, volume of a geometric figure is defined as the amount of space occupied by the object or figure in three-dimensional space. Volume is measured in cubic units.
The volume of a cube is equal to the measure of its side to the cube. That is to say:
Volume = side x side x side = side³
<h3>This case</h3>
In this case, you have a cube with a side length of 3 centimeters. Replacing in the definition of volume:
Volume= 3 centimeters× 3 centimeters× 3 centimeters
Solving:
<u><em>Volume= 3 cm³</em></u>
Finally, the volume of a cube with a side length of 3 centimeters is 3 cm³.

Answer:
Like all viruses, phages are simple organisms that consist of a core of genetic material (nucleic acid) surrounded by a protein capsid. The nucleic acid may be either DNA or RNA and may be double-stranded or single-stranded.

Explanation:
Geographic Information Systems (GIS) store, analyze and visualize data for geographic positions on Earth’s surface. GIS is a computer-based tool that examines spatial relationships, patterns and trends. By connecting geography with data, GIS better understands data using a geographic context.
