Blood pressure is highest in the arteries near the heart

Blood pressure is determined both by the amount of blood your heart pumps and the amount of resistance to blood flow in your arteries. The more blood your heart pumps and the narrower your arteries, the higher your blood pressure. A blood pressure reading is given in millimeters of mercury (mm Hg). It has two numbers.

Answer: Blood pressure is highest in the arteries near the heart.

Explanation: In the arteries, the hydrostatic pressure near the heart is very high while in the case of arterioles the rate of flow reduces (but pressure increases) as the openings of the arterioles become narrow. Thus these two tubules have thick muscular walls. While the veins and venules have lower pressure and thus their walls are also thin and less muscular.

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).
