The two main points from Darwin's theory of evolution is that 1) most, if not all living organisms evolved from one or just a few common ancestors and that subsequent specialization of further generations then led to new species. Furthermore, he said that 2) the process how this was done was by natural selection where the organisms which were most adapted to their environment were successfully 'remembered in the gene pool'.
Answer:
I assume you are referring to bees?
Explanation:
From what I know and this is just surface level knowledge, she is the one who births the hive and usually designates their purpose once she has laid the eggs. She herself does not do much, she is just the one that the infrastructure of the hive follows in maintaining the hive itself. I hope this helps. Good luck!

Typhitis, also called neutropenic enterocolitis, is an infection that often develops in cancer patients who undergo chemotherapy. In many cases, surgical intervention is required.
Without surgical intervention, the patient would be transferred to an ICU (Intensive Care Unit) for monitoring, and the nurse would perform some or all of these emergency actions:
1. Bowel rest and nasogastric suction,
2. Serial abdominal examinations,
3. Providing intravenous fluids, blood, and platelet transfusions when needed,
4. Using antibiotics to fight the infection, and obtaining cultures to determine if the antibiotic is working,
5. Not administering medication that could worsen the situation.
Mechanical stress applied to bone increases osteoblast activity in bone tissue, and the removal of mechanical stress decreases osteoblast activity.
Explanation:
Osteoblasts are cells , that are produced in the bone marrow and are responsible for formation of bones and bone matrix.
Whenever a mechanical stress is applied on the bones , a series of reactions are triggered. As a result the activities of osteoblast increases to synthesize more and more bone matrix to provide strength.
Again on the other hand a decrease in mechanical causes a decrease in the activities of the osteoblasts.
