Answer:
The expression of genes associated with drug resistance leads to the reduction in the effectiveness of drugs against cancer cells.
Explanation:
In cancer, drug resistance is produced when oncogenic cells are able to develop mechanisms of resistance against drugs such as, for example, chemotherapeutic agents. In these cases, therapeutic treatments become ineffective to fight against cancer cells and tumor progression. In consequence, it is imperative to trace the expression of target oncogenes associated with drug resistance in order to provide effective treatments to eliminate cancer cells.
Answer:
A vacuole is a membrane-bound organelle. They are a kind of vesicle. Vacuoles are closed sacs, made of membranes with inorganic or organic molecules inside, such as enzymes. They have no set shape or size, and the cell can change them as it wants.
Explanation:
Water is predominantly found in cell sap. It serves as a storehouse for the plant cell to act as a storage place for excess nutrients. A vacuole is a membrane-enclosed fluid filled sac.
The main 'job' of the endocrine system in most animals is to moderate and send out chemicals that affect other organs, tissues, and organ systems of the body.
Make an appointment with your doctor if you're feeling fatigued for unexplained reasons. Some anemias, such as iron deficiency anemia or vitamin B-12 deficiency, are common.
Fatigue has many causes besides anemia, so don't assume that if you're tired you must be anemic. Some people learn that their hemoglobin is low, which indicates anemia, when they go to donate blood. If you're told that you can't donate blood because of low hemoglobin, make an appointment with your doctor.
