The nurse should explain the newly diagnosed lung cancer client that the reason why his tumor metastasized so fast without displaying many signs/symptoms is that: the malignant tumors affect area tissues by releasing enzymes and toxins that make the other normal cells to differentiate uncontrollably.
Metastasis is the property of spreading of cancer cells. When the tumor at a location in the body starts spreading top other locations as well, it is said to be metastasizing.
Malignant tumors are those that metastasize. They travel to near or distant locations at the body and start dividing. These are cancerous in nature.

<span>Human cells contain 23 chromosomes and has a total of 46
pairs of chromosomes. The answer is letter A. Depending on the length and
morphology, it has seven groups. They are arranged from largest to smallest. It
has 22 pairs of homologus chromosomes known as autosomes and 1 pair of sex chromosomes,
a total of 23 chromosomes. A male karyotype has a total of 46 chromosomes and
gives a pair of XY while a female karyotype has a total of 46 chromosomes and
gives a pair of XX. These pairing are responsible to the gender of the
offspring.</span>

Answer:
This question lacks options, the options are:
A) 100 ml Beaker
B) 250 ml Erlenmeyer Flask
C) 250 ml Graduated Cylinder
The answer is B). 250 ml Erlenmeyer Flask
Explanation:
Several types of glasswares are used in chemical laboratories for performing processes like mixing, heating and stirring of chemicals. In this question, Dr. Malani Mackey who works for a pharmaceutical company is trying to develop a cancer drug by making a mixture of L-histidine, polysorbate 80, and sucrose. This mixture is required to be heated and stirred (shaked) during the mixing. Hence, a glassware adapted for this purpose must be used.
- Erlenmeyer Flask, also known as Conical flask is a laboratory flask named after its conical base/bottom. This glassware is used to mix and even heat chemicals in the laboratory. Due to its cone-shaped body coupled with a long cylindrical neck, the contents in the Erlenmeyer Flask can be shaked or stirred without spilling them. This property gives the ERLENMEYER flask an edge over the BEAKER (has a large open mouth) when used for stirring purposes.
The Graduated cylinder is best suited for making precise measurements of liquid chemicals, hence, it is not an appropriate glassware for heating and stirring.
