Process of Sexual Reproduction for honey bees
zalisa [80]

Answer:

The typical story of reproduction is that males and females of an animal species do it sexually. Generally, that's what honeybees do, too. Sperm from a male drone fertilizes a queen's eggs, and she sends out a chemical signal, or pheromone, that renders worker bees, which are all female, sterile when they detect it.

Explanation:

In the Cape bee, female worker bees are able to reproduce asexually: they lay eggs that are essentially fertilized by their own DNA, which develop into new worker bees. The team sequenced the entire genomes of a sample of Cape bees and compared them with other populations of honeybees that reproduce normally

Suggest one advantage and one disadvantage of<br>using a dichotomous key to identify something.​
prisoha [69]
Advantage: Dichotomous keys are very useful because they allow non-expert users to identify organisms by directing them to look at the known, important organisms. Disadvantage: Disadvantage of dichotomous keys is that if a single wrong decision is made at any juncture, a wrong identification will result. Sometimes it becomes obvious that an error has been made, and you can retrace your steps until you get back on the right track, but this is not always the case
