Answer: 43 x 10^6 CFU.
Explanation:
Plate count is a method used to determine the number of viable microorganisms in a sample. When the bacterial concentration is high, serial dilutions are carried out in a 1:10 sequence. <u>Then, the dilutions are successive dilutions keeping the dilution factor constant at each step</u>. Small aliquots of these dilutions are seeded in medium contained in a Petri dish where the bacteria grow forming colonies. Then the plates are incubated and colonies develop both within the agar and on the surface.
If the concentration of the seeded aliquot is too high, the bacteria will grow too much and it will not be possible to distinguish the colonies. <u>However, if the concentration is very low, the number of colony forming units (CFU) may be very low and thus can be counted</u>.
Colony forming units are calculated:
CFU = Number of colonies / (volume seeded on the plate * dilution).
The dilution is 10^-6, the number of colonies counted is 43, and usually the volume plated is 0.1 mL, so we replace that in the equation:
CFU= 43 / (0.1 mL * 10^-6)
CFU= 43000000 = 43 x 10^6
The component of urinalysis that reflects the amount of waste products and solids in urine is called Specific Gravity
A urine test examines the various elements in urine.
The kidneys filter the blood to remove waste products, minerals, water, and other chemicals that are then excreted in the urine. There are countless distinct bodily wastes in urine.
Urine can be used in more than 100 different tests. The tests for color, clarity, odor and specific gravity are frequently performed as part of a routine urinalysis.
The amount of chemicals in the urine is measured using specific gravity. Additionally, it demonstrates how effectively the kidneys regulate the amount of water in urine.
The more solid stuff there is in the urine, the greater its specific gravity. When you consume a lot of liquids, your kidneys produce urine with low specific gravity and high water content. Your kidneys produce urine with high specific gravity and little water when you don't drink any fluids.

The organelle in the plant that will most likely store the absorbed herbicide waste is the vacuole. Vacuoles act as storage bubbles in plant cells. They could store various materials such as food or nutrients to help the plant survive. It can also store waste materials to prevent them from contaminating the entire cell.
I think it’s d but I’m not sure
Since ribosomes produce proteins, and the endoplasmic reticulum transports the proteins that the ribosome makes it is advantageous for a protein secreting sell to have ribosomes on the endoplasmic reticulum so that the proteins can be transported more quickly and efficiently
