Answer:
Malignant tumors are cancerous. They develop when cells grow uncontrollably. If the cells continue to grow and spread, the disease can become life threatening. Malignant tumors can grow quickly and spread to other parts of the body in a process called metastasis.
When the patient who is nothing by mouth (NPO) (no food or fluids allowed) develops an adverse reaction to a new intravenous (IV) drug, then the nurse will take action like recording the reaction, stopping the further administration of the drug and notify the health care provider.
Nothing by mouth (NPO) is a period of time in which the patient is advised not to eat or drink anything. Doctors suggest avoiding eating food or drinking water during the medical or surgical procedure to ensure the correct report or successful operation of the patient.
NPO is a common practice, and it instructs that patients should not take solid and liquid before receiving general anaesthesia.

Answer: False
A lake is a water body that is surrounded by land. The water in the lake comes from melting glaciers, rain, groundwater, rivers. Lake formation also occurs when a water body is restricted to it's natural flow. Erosion due to wind and water will limit the life of lake. As, soil removed during landslides or mudslides from hills or mountains get settled as debris at the bottom of lake will cause water pollution. Also, soil coming from agricultural field through water will carry in it fertilizers ,which will promote excessive plant and algal growth in lakes therefore, oxygen content of lake water will decrease which lead to death of animals residing in lake hence, will ultimately lead to water pollution ,which will be responsible for limiting the life of lake.
B is the answer to your question! hope I helped!!!
D. Species with an odd number of chromosome sets (triploid and pentaploid) would be infertile.
E. Aneuploid individuals (monosomic and trisomic) would have reduced fertility.
Explanation - Chromosomes generally happens to occur in the set of two. Organism that have more than two sets of chromosome are called polyploids. Polyploids that have odd or uneven count of sets of chromosome are sterile or fully infertile.
Example - triploid (3n), pentaploid (5n) because their gametes and offsprings are aneuploid. Aneuploidy is addition of entire chromosome to the already existing normal set of chromosome. Aneuploids are unable to produce viable offspring because their fertility got decreased as the zygote formed after the fertilization itself is aneuploid.
