Answer:
The correct answer is B. In the human eye, the greatest amount of refraction occurs when the light passes from the air into the cornea.
Explanation:
The ocular refraction refers to the refraction that occurs in the light coming from the objects when crossing the different parts of the eye, causing the images to concentrate on the retina.
When the light rays, after crossing the cornea and the lens, are projected on the retina at a single point creating a clear image that is transmitted to the brain for processing, we talk about normal refraction.
The answer is the Ribosomes of mitochondria and plastids are very similar in their structure and function to bacterial ribosomes.Mitochondria, chloroplasts, and bacteria are alike in size. Bacteria also have DNA and ribosomes alike to those of mitochondria and chloroplasts. Based on this and other proof, experts ponder host cells and bacteria shaped endosymbiotic relationships precedent, when separate host cells took in oxygen-using and photosynthetic bacteria but did not put an end to them.
Mutation is the source of differences in the dna code.
What is Mutation?
- A mutation is a permanent change in the DNA sequence of an organism.Errors in DNA replication during cell division, exposure to mutagens, or viral infection can all cause mutations.
- Somatic mutations (which happen in body cells) cannot be passed on to offspring, whereas germline mutations (which happen in eggs and sperm) can.
- Damaged DNA can change by base pair replacement, deletion, or insertion. The majority of the time, mutations are benign, unless they result in tumor growth or cell death. Cells have developed systems for repairing damaged DNA due to the deadly potential of DNA mutations.
