Answer:
The correct answer is biological.
Explanation:
When any pathogen invades the body, it has to pass several lines of defence. The first barrier is the skin and mucous membrane which is a physical and chemical barrier. The second line of defence is the non-specific response by macrophages, neutrophils and interferon. After crossing these two barriers the third line of defence comes into action in which, the B- cells and T-cells act specifically on the pathogen and destroy it.

Water moves from the soil to the leaves of mesophytes by osmosis and xylem conduction.
<h3>What are mesophytes?</h3>
Mesophytes are plants that are adapted to moderate water environments only. In other words, they cannot survive extremely or extremely wet environments.
Water moves from the soil to the leaves of mesophytes as follows:
1. Water moves into the root hair by osmosis
2. Water is conducted upward from the root hairs by special cells known as xylems.
3. Conducted water reaches various plant parts, including leaves.

Answer:
A
Explanation:
monosaccharide is derived from mono, meaning "one", and saccharide, meaning "sugar". The common monosaccharides are glucose, fructose, and galactose. Each simple sugar has a cyclic structure and is composed of carbon, hydrogen and oxygen in ratios of 1:2:1 respectively. Although each sugar mainly exists as a cyclic compound, it is important to note that they are all in equilibrium to a small extent with their linear forms.
While galactose and glucose are composed of six-membered rings, fructose has only five carbon atoms bonded to each other in ring form.
