The majestic horse chestnut, whose flowering is more pollen-rich than nectar-rich and begins in April–May, provides bees with a valuable cue that attracts them to flowers that have not yet been pollinated.

<li>consumes <strong>less</strong> energy at 2 °C than at an internal hive temperature of 15 °C.</li>
<li>consumes <strong>the same amount of energy</strong> at 2 °C and at 15 °C because the cluster contracts as the internal hive temperature decreases.</li>

- The more the temperature inside the hive decreases, the more the temperature of the core increases.
- The more the temperature inside the hive decreases, the more the temperature of the outer mantle of the cluster increases.
- The more the temperature inside the hive decreases, the more the temperature of the outer mantle of the cluster decreases, potentially dropping to as low as +2°C.

(one or more answers possible)
- It is a protein that slows down the “ageing” of worker bees?
- It modulates foraging behaviour by favouring pollen collection over nectar collection?
- It does not extend the lifespan of the queen?
- It is synthesised in the bee’s fat body?
- It does not stimulate the hypopharyngeal glands and the production of royal jelly?
- It is not involved in the immune mechanisms of bees?
- It modulates the social life of the entire colony?

Photo of a bee with wings held in a cross (or K-shaped) position.
What should be thought about this bee?
- The insect positions its wings to release a trail pheromone that allows nearby foragers to relocate the nectar source.
- In case of high temperature, the bee stretches its wings to facilitate heat dissipation.
- Bee infected with acarine disease

On a fine day at the end of May, you observe numerous bees clustered in front of the hive entrance:
You infer that:
- A swarm is preparing to depart.
- The “climate bees” are ventilating to reduce the humidity of the abundant spring nectar flow.
- The workers are performing a calling behaviour to guide the foragers back to the hive.

Which answers are correct?
1. Epigenetics directly modifies the DNA sequence.
2. Epigenetics modulates gene expression without modifying the genome.
3. Epigenetic mechanisms are always stably transmitted across several generations.
4. Epigenetics is influenced only by hereditary factors and not by the environment.
5. Unlike genetics, epigenetic mechanisms are reversible.
6. Epigenetic modifications have no effect on the phenotype.
