Answer:
The correct answer is B. Myopia is also known as nearsightedness.
Explanation:
Myopia is a refractive defect of the eye in which parallel light rays converge at a focal point located in front of the retina, instead of converging on the same retina; it is the inverse defect to farsightedness, in which the light rays reach the retina before converging.
A person with myopia has difficulty focusing well on distant objects, which causes visual acuity deficits and can also lead to headaches, strabismus, visual discomfort and eye irritation.
The increased temperature melts glaciers, ice caps etc. and thus increases the sea levels
Answer:
Gene expression is the process by which the information encoded in a gene is used to direct the assembly of a protein molecule. The cell reads the sequence of the gene in groups of three bases.
Explanation:
Answer:
The correct answer would be - complex eyes evolved in the gradual steps, each of which was fully functional and adaptive in improving visual acuity.
Explanation:
The natural selection of the complex traits such as the vertebrate eye (complex eye) are seems to be problematic, many biologist think that the complex eyes evolution is take place in gradual steps and each step of this evolution was adaptive and functional in improving the visual acuity.
The steps that were involved are like light sensitivity patch, a deepening hole or pit that help in sharp vision and many other random evolution steps.
Thus, the correct answer is- complex eyes evolved in the gradual steps, each step of this evolution was fully functional and adaptive that helps in improving visual acuity.
Answer:
Option A, Donates H+ ions when conditions become too basic and accepts H+ ions when conditions become too acidic
Explanation:
Buffer solutions have the ability to maintain stability of pH of the solution. They resist any changes in the pH of the solution on addition of an acid or a base component or solution.
Every buffer solution has a buffer capacity and range. Buffer capacity depicts the amount of acid or base solution is required to change the pH of the solution by 1
.
Hence, option E is correct
