Taxol is a drug that comes from the bark of a tree that binds and irreversibly stabilizes microtubules. It is often used during chemotherapy to kill dividing cancer cells. How does taxol block cell division?
A-
Taxol prevents the contractile ring from forming and dividing the cell in two.
B-
Taxol prevents DNA replication.
C-
Taxol prevents chromosome condensation during prophase.
D-
Taxol prevents spindle formation and separation of chromatids.
Answer: D-
Taxol prevents spindle formation and separation of chromatids.
Explanation:
The Taxol is used as an anticancer drug formulation. It is obtained from yew tree. An anticancer drug affects the cell cycle machinery so as to limit the production of cancer cells. This drug ceases the microtube formation in animal cells. This prevents the spindle fiber formation and further prevents the mitosis of cancerous cancers as the chromosomes will not separate apart and so abnormal cells will not produce further.
Answer:
To attract pollinators.
That's why they're always such bright colours.
Neonates are at a higher risk of developing respiratory complications upon administering general anesthesia
Explanation:
Anesthesia can lead to a number of perioperative and postoperative respiratory complications especially in neonates. Neonates may require varying levels and types of anesthesia for various conditions starting from central line or VP shunt placement, tracheostomy or gastrostomy tube placements, any excisions, circumscision and any other surgical procedures.
The immature neonatal respiratory system makes neonatal anesthesia a difficult task due to:
Anatomically, the airways are small and alveoli network is immature.
Physiologically, neonatal metabolic rate is very high with more oxygen consumption than adults
Functionally, the lung mechanism is also immature, smaller upper airway resistance and higher lower airway resistance which causes collapse.
Hence, proper care should be taken while anesthetizing neonates with proper communication with the healthcare team including pediatric surgeons, pulmonologist, cardiologist, nursing care, pharmacists etc
Intracellular fluid contains high levels of k , large anions, and proteins.
<h3>What is Intracellular fluid?</h3>
- Fluids are bathed inside and outside of human cells. In actuality, the water that is present inside each cell accounts for 42% of the body's weight. Intracellular fluid is the term for the fluid found inside cells (ICF).
- Extracellular fluid (ECF), which refers to all fluid present outside of the cell, is distinguished from intracellular fluid by the semipermeable membrane that encloses it.
- This membrane permits fluid to pass through and leave while blocking the entry of undesirable chemicals or components. Water, proteins, and dissolved solutes are all present in intracellular fluid.
- The solutes are electrolytes, which support the healthy operation of our body. An element or substance that separates into ions when dissolved in fluid is known as an electrolyte.

Answer:
A. Most plats in the ditch will be plants with long roots.
Explanation:
Because the plants with shallower roots systems are easily uprooted by the rain, and there is lots of rain that year, natural selection will choose the long rooted plats. They are the "strongest" in evolution's eyes because they are less likely to die by being uprooted.
