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).

Failure in a particular structure of the heart tends to cause a backup of blood in the lungs, known as pulmonary congestive hear
xeze [42]

Answer:

Left ventricle.

Explanation:

Human heart is divided into four chambers - two auricles and two ventricles. Heart acts as the pumping organ and carries both oxygenated and deoxygenated blood in the right and left ventricles.

The failure of functioning of any chamber of heart may cause a particular disease in the individuals. The pulmonary congestive heart failure occurs due to the failure of the left ventricles of the heart. The left ventricle carries blood from heart to the body tissues, its failure leads to the backup of blood in the lungs.

Thus, the answer is left ventricle.
