Answer:
True
Explanation:
CSF is produced by choroid plexus. It starts flowing from the lateral ventricles and move towards the fourth ventricle via the third ventricle. It then moves towards the subarachnoid space which is the region surrounding the brain and spinal cord. From the brain and spinal cord, CSF is absorbed through the blood vessels and passed into the bloodstream again. It then moves to the kidney and liver for filtration.
Hence, give statement is true
C
Explanation
Meiosis 2 is similar to mitosis because it separates the chromosomes to have sister chromatids in each cell. In both processes, you are separating the chromosome and dividing the cell to make 2 cells out of 1 (the only difference is that in meiosis, you're doing that for 2 cells to get 4).
<span>B, enzymes will denature at that temperature. Sucrase has an optimal temperature of about 37 degrees celsius so 1000 would definitely be too high for them to work.</span>
Answer: Complementary base- pairing creates a very stable structure
Explanation:
The colourless colonies are only the gram-negative bacterium that will grow as the selective media Eosin Methylene Blue (EMB) followed by mannitol salt agar (MSA), which will only allow one type of microorganism to grow.
Eosin Methylene Blue (EMB) agar is a differential microbiological medium that gives a colour indicator to distinguish between organisms that digest lactose and those that do not while significantly inhibiting the development of Gram-positive bacteria. In laboratories, the selective medium is crucial for differentiating gram-negative microorganisms.
Both EMB (Eosin methylene blue) and Mannitol Salt Agar (MSA) are selective in that they only permit the growth of Gram-negative bacteria.
