Whether or not the article describes persenal experience is the major determining factor in this question. If the article tells the story of another, it is secondary, if the article was written by someone who is recounting on their experience, it is first peron. Hope this is clear and understandable.

6. Why does meiosis increase genetic variation in the offspring, but mitosis does not? (1 point)
brilliants [131]
Meiosis involves crossing over where chromosomes exchange genetic segments, resulting in different sets of chromosomes. Each time an egg or sperm created, it is different due to this recombination. Mitosis on the other hand is non-sex cells replicating exact copies of themselves which lead to no genetic variation as they aren't involved in producing offspring.

1. John observed bacteria at 100X under the oil immersion and then decided to go back to 40X
weeeeeb [17]

Answer:

The observed image will not be sharp

Explanation:

When 100x microscope objective lens is being used, light refraction in the air is enough high to produce image alterations. Image distortions can be minimized by immersion oil because this liquid has a higher refractive index than air. However, light refraction is not usually noticeable when using 4x, 10x and 40x objective lenses. Moreover, this image will not be sharp after putting oil on the slide and going back to the 40x objective, it is for that reason that the 40x is called 'high dry' lens. In consequence, it is required to clean the immersion oil off the 40x objective. In general, it is required to  to remove the oil and refocus off the slide and lens immediately after oil immersion (it can be done by using an oil-soluble solvent).
