20 heterozygous purple flowering pea plants are crossed. If purple is dominant over white, what are the expected phenotypic results?

Answers

Answer 1

Answer: Let's call the colour alleles C for dominant purple, and c for recessive white.

We have crossed Cc with Cc. So if we put that in a Punnett square, we'd have a CC, two Cc and a cc. That would give us a 3:1 ratio of purple to white, so you'd expect 15 purple and 5 white flowers. :)

If you are administering a drug with a dosing rate of 50 mg/kg to a patient with a mass of 50 kg, how many mg of drug do you need to deliver to the patient?O 25 mg
O 2,500 mg
O 250 mg
O 2.5 mg
O 50 mg

Answers

0.330 and the 3 is what you rounded up

Final answer:

To calculate the dosage of a drug given in mg/kg for a person, multiply the dosing rate by the person's mass. In this case, the dosing rate is 50 mg/kg and the mass of the person is 50 kg, yielding a total dosage of 2,500 mg.

Explanation:

When administering a drug with a dosing rate that is given in mg/kg, you need to multiply the dosing rate by the patient's mass to determine the proper dosage. In this case, we use the formula:

Dose = Dosing rate × mass

Substituting the given values into the formula:

Dose = 50 mg/kg × 50 kg, which equals to 2,500 mg.

Therefore, you need to administer 2,500 mg of the drug to the patient.

In 1668, Francesco Redi conducted an experiment with jars of meat. This experiment was noteworthy because it _____.proved that meat should be refrigerated
disproved that life can generate from nonlife
proved that meat does produce maggots
disproved that meat was bad for you

Answers

Answer: Disproved that life can generate from nonlife.

Explanation:

The theory of spontaneous generation stated that life could arise from nonliving objects.
To test this theory, Redi conducted an experiment in which he took jars and placed a piece of meat in them. He covered some jars with a muslin cloth and left some of them open.
After some time he observed that maggots developed only in the open jars and not in the covered ones.
From this, he was able to conclude that life did not spontaneously originate from non-living matter because had it been the case, the covered jars would also have the maggots but since the flies could no enter the jar there were no maggots in them.

Answer:

Disproved that life can generate from nonlife.
