4 0

Answer:

Explanation:

From the given information:

Since 300 ml of intravenous infusion contains 300 mg of drugs;

Then; 1 ml of intravenous infusion contains (x) amount of drugs

(x) amount of drugs = (300 mg × 1 ml)/ 300 ml

(x) amount of drugs = 1 mg.ml

To calculate the drip rate in drops/minutes by applying conversion factors.

rate (\dfrac{ in \ drops }{minute })= \dfrac{2 \ mg }{min } \times \dfrac{20 \ drops}{1 \ ml} \times \dfrac{1 \ ml }{1 \ mg }

rate (\dfrac{ in \ drops }{minute }) = 40 \  drops / min

The complete orbital notation diagram of an atom is shown. Five squares are shown aligned horizontally. Inside the first square
Jlenok [28]

Answer:

l = 0, 1, and 2; it is in a d orbital.  

Explanation:

1. Angular momentum quantum number

One square means l = 0.

Three squares mean l = 1.

Five squares mean l = 2.

If an atom contains electrons with l = 2, it must also have electrons with l = 0 and 1.

Thus, the electrons in the atom can be assigned the angular momentum quantum numbers l = 0, 1, and 2.

Those in a set of five squares all have l = 2.

2. Location of electron

The last electron is the lone electron in the fifth square. Since l = 2, the electron is in a d orbital.

How are tumor cells different from normal cells
In-s [12.5K]

Tumor cells differ from normal cells in that A) Mitosis is not regulated in tumor cells.


This is seen when tumors grow to large amounts rather quickly. Mitosis is not regulated, and therefore the cells continue to multiply and that is when we are able to see and feel a palpable cancer mass - their growth is uncontrolled.
