6 0

<u>Answer</u>: A) They have been geographically isolated from each other for a longer time.

<u>Explanation</u>: An isthmus is defined as a narrow strip of land that separates two bodies of water as well as connecting two larger landmasses at the same time. Thus, an isthmus if an efficient physical barrier that has separated an original shrimp species. This has resulted in the extant deep-water shrimp species through the evolutionary process known as allopatric speciation.

The age of an isthmus is in the range of at least two million years. Thus, the two deep-water shrimp species have been separated from each other for a very long time.

A student needs to prepare 250 mL of a 0.550 M aqueous solution of sucrose, C 12 H 22 O 11 ( aq ) , which is used frequently in
Grace [21]

Answer:

Dissolve 47.025 grams of sucrose in enough water to produce 250 ml of solution.

Explanation:

You need to prepare 250. mL of a 0.550 M aqueous solution of sucrose, C12H22O11 (aq),

which is used frequently in biological experiments.

Based on your answer above, what is the value of x?

Solution:

A 0.550 M aqueous solution contains 0.550 mole of sucrose per liter of solution.

250 ml = 0.250 liter

Thus a 0.250 liter of a 0.550 M aqueous solution of sucrose contains 0.250 * 0.550 = 0.1375 mole of sucrose

Recall:

Mass = number of moles * mass of 1 mole

mass of 1 mole of C12H22O11

= 12(12) + 1(22) + 16(11)

= 144 + 22 + 176

= 342 grams

Mass = 0.1375 * 342 = 47.025 grams of sucrose.

Dissolve 47.025 grams of sucrose in enough water to produce 250 ml of solution.

A client whose parkinson's disease is being treated with tolcapone should concurrently take what drug?
steposvetlana [31]

Answer:

The correct answer would be levodopa/carbidopa.

Tolcapone is a drug used as an adjunct to levodopa/carbidopa combination medication.

These drugs are used to treat the symptoms of Parkinson's disease.

Tolcapone is used to inhibit enzyme COMT (catechol-O-methyl transferase).

In the brain, levodopa is converted into dopamine which helps in controlling the movement.

Carbidopa helps in preventing the breakdown of levodopa in the blood which allows more levodopa to enter the brain. In addition, it helps in reducing the side-effects associated with levodopa such as vomiting, nausea et cetera.
