Answer:
The word adapt means to get adjusted to a change.
yes, survival in a certain environment is similar to evolution. Both must use adaptation in order for life to keep living through changes in the environment. Each help life sustain itself in a very unique way.
Explanation:
This is due to the fact that only homologous chromosomes would have identical genes located at identical sites on those chromosomes. Otherwise, there would be no connection between the alleles of various genes.
Although the genes and loci of the two members of the homologous pair are similar, the alleles may vary.For instance, both allele possess the genes responsible for the attribute of eye colour. While the one has alleles for the blue-eye trait, other has alleles for the brown-eye trait. The homologous chromosomes are said to be heterozygous in this instance since the alleles are different.
On the other hand, when both alleles for a gene that codes for the blue-eye phenotype are present, it is said to be homozygous.

Staphylococcus epidermis appears stained, whereas Escherichia coli appears stainless after the gram stain.
Staphylococcus is a Gram-Positive Bacteria i.e. it takes up the Gram stain.
Escherichia coli or E. coli is a Gram-Negative Bacteria i.e. it does not take up the Gram stain.
Gram Staining is done by immersing the bacterial sample in a solution of dye and then observing it under microscope after proper rinsing.
Gram Positive Bacteria are those bacteria that show a positive outcome on staining. Gram Positive Bacteria appear Stained after staining.
Gram Negative Bacteria are those bacteria that show a negative outcome on staining. Gram Negative Bacteria does not take up the stain and appear stainless.
The epidermis of Staphylococcus which is a Gram-Positive Bacteria appears to take up the stain whereas Escherichia coli which is a Gram-Negative Bacteria does not take up the stain.
Staphylococcus epidermis appears stained, whereas Escherichia coli appears stainless after the gram stain.

History of the Atom Reading Comprehension is stated below.
The Greek word atoms, which implies unable to cut or divide, is where the name "atom" originates. The atom was believed to be invisible at that time. In contrast to Democritus, Aristotle presented his own theory regarding the nature of matter. Democritus' thesis provided a clearer explanation of the situation, but Aristotle's ideas won out because of his greater stature.
According to his ethics, the only way to acquire eudaimonia—a state of bliss or contentment that is the highest form of human life—is by becoming wonderful. Dalton eventually looked more closely at gases as a result of his fascination with atmospheric pressures. John Dalton is well recognized for his contributions to human optics and for introducing the atomic theory to chemistry.
After discovering the electron, Thomson went on to suggest a model for the atom's structure. In Thomson's "plum pudding" atom model, a positively charged "soup" was surrounded by negatively charged electrons. Thomson made this discovery after his research assistant Francis Aston used a mass spectrometer to fire ionized neon through a magnetic and electric field and noticed two unique deflections. Thomson came to the conclusion that neon existed in two isotopes with distinct masses.
