Answers

Answer 1

Answer:

278 ml of lidocaine and 222 ml of water are needed to make the solution.

Explanation:

Given that I have been asked to make 500 mL of 50% dexamethasone solution from a 90% dexamethasone stock solution, to determine what volume of the stock lidocaine and what volume of water do I need, I need to perform the following calculation:

100 x 0.90 + 0 x 0 = 90

90 x 0.90 + 10 x 0 = 81

80 x 0.90 + 20 x 0 = 72

60 x 0.90 + 40 x 0 = 54

55 x 0.90 + 45 x 0 = 49.5

56 x 0.90 + 44 x 0 = 50.4

55.5 x 0.90 + 44.5 x 0 = 49.95

55.6 x 0.90 + 44.4 x 0 = 50.04

500 x 0.556 = 278

Thus, 278 ml of lidocaine and 222 ml of water are needed to make the solution.

Explain how getting sick is both a cause and effect of a lack of homeostasis.
plz answer in a simplified term .

Answers

Homeostasis is the process in which the body maintains normal, healthy ranges for factors such as temperature, energy intake and growth. The immune response contributes to homeostasis by preparing the body to fight off infection and to help the healing process in case harm occurs. During infection, the immune system will cause the body to develop a fever. The immune system also causes an increase in blood flow to bring oxygen and other immune cells to sites of infection. The immune system also helps wound healing, so that proper barriers in organs can be reformed such that those organs can correctly participate in homeostasis.

Answers

Answer:

Explanation:

What is an Experimental Problem? An experimental problem is:

Specific A questionTestable Science-based, not pertaining to another subjectUnbiased

Step One: Right off the bat, we can eliminate A because it's not a question, and an experimental problem is supposed to be a question.

Step Two: Now that we have all questions, we have to figure out which one is too broad. We can eliminate B because although it is not too broad, it is nto specific enough, and is not necessarily science-based.

Step Three: We are between C and D, and the answer is C because it is specifically asking about a pill. In D, it is not necessarily about science, and the question needs to be more specific; it needs to be something that can be explained. With D, it is hard to test, whereas, with C, the main goal is to test.

C is the answer.
