Answer:
Gaseous exchange, or respiration, is the process in which terrestrial plants take in oxygen from the air and release carbon dioxide. It involves a series of biochemical processes that take place within specialized cells embedded within the plant's leaves.
The first step of gaseous exchange in terrestrial plants is diffusion, where molecules move from an area of high concentration to an area of lower concentration. In this case, atmospheric oxygen diffuses into leaf cells through small openings on their surface called stomata. As these molecules enter the leaf cells, they are taken up by specialized photosynthetic organelles known as chloroplasts.
Chloroplasts then absorb energy from sunlight and use it to combine CO2 with water (H2O) to produce sugars and other organic compounds such as amino acids and lipids (photosynthesis). The resulting reaction produces chemical energy stored in the form of ATP (Adenosine Triphosphate). This ATP drives various metabolic pathways that use oxygen as well as glucose for cellular respiration. During this process, some oxygen enters the cell while some carbon dioxide is released back out into the atmosphere through small openings on their surface called stoma – completing the cycle of gas exchange between terrestrial plants and their environment.

(B) Protein-coding genes and noncoding DNA make up about the same amount of the human genome.
(C) Protein-coding genes make up far more of the human genome than noncoding DNA.
(D) Noncoding DNA has not been found in humans.
Answer:
(A) Protein-coding genes make up far less of the human genome than noncoding DNA.
Explanation:
The human genome contains both protein-coding and non-coding sequences. However, the non-coding sequences make most of the human genome as they account for as much as 98.5% of the total human genome. The non-coding part of the human genome serves other important functions such as promoter, enhancers, silencers for gene expression.
An only small part of the human genome serves as protein-coding genes and make exons.
B. In many houses the Prussian officer ate at the same table with the family.
C. By the exercise of tact the number of men quartered in one's house might be reduced; and why should one provoke the hostility of a person on whom one's whole welfare depended?
D. And foolhardiness is no longer a failing of the citizens of Rouen as it was in the days when their city earned renown by its heroic defenses.
E. Out of doors, therefore, citizen and soldier did not know each other; but in the house both chatted freely, and each evening the German remained a little longer warming himself at the hospitable hearth.

The above two lines from "Guy de Maupassant's short story "Boule de Suif" shows that the relation between the French and German people remained friendly despite the war.
