Where do queen bees lay eggs and larval bees are fed by worker bees
steposvetlana [31]

Answer:

1. Queen bees lay their eggs after within each cell inside a honeycomb.

2. True. Worker bees feed the larvae with a combination of nutrients, from nectar and pollen to bee milk and water.

Explanation:

1. Queen bees lay their eggs after within each cell inside a honeycomb (hive) <em>[</em><u><em>See image below]</em></u><em> </em>during the winter.

The queen is able to lay over two thousand eggs PER DAY! Each egg has an approximate size of 1 mm long. This process then leads to the formation of a whole new colony of bees.

<u><em></em></u>

2. True.

Worker bees have the largest density of all, that is, there are numerous worker bees within a colony. As their name "worker" implies, they have plenty of tasks to perform. For example, they have to clean the hive regularly, ventilate it during warm conditions or keep it warm during cold conditions, and also care for the queen. However, one the most important roles of workers is to feed the larvae, during this stage they are also called "nurse bees." These bees feed the young with a combination of nutrients, from <u>nectar and pollen to bee milk and water</u>.

ATP is an unstable molecule, which means it will release energy when it becomes reduced to ADP, meaning it will break off one of its phosphate groups.
