Answer: WAGGLE DANCE is the dance that provides honey bees information about both the direction and distance of food.
Explanation:
Honey bees are flying insects that helps in the pollination of plants as they collect nectar and pollen from plants for food. As the name implies, they are known for the production of honey.
The honey bee dance helps in social organization of the honey-bees which is established by the living of all individuals within the colony and they show the mutual cooperation among the members of the colony, and exhibit the overlapping generations.
WAGGLE DANCE is the dance that provides honey bees information about both the direction and distance of food for the colony. It consists of two phases:
- the WAGGLE phase and
- return phase which occurs in a regular alteration pattern by foragers. It involves running through a small figure-eight pattern.
Answer:
Gap junctions
Explanation:
Gap junctions form pores that connect adjacent cells. In this way signaling molecules, ions and other substances can pass through the pore to the adjacent cell. This type of cell junctions are important in cardiac muscle responses, in brain signaling, during childbirth, etc.
Answer:
The direct threats of invasive species include preying on native species, outcompeting native species for food or other resources, causing or carrying disease, and preventing native species from reproducing or killing a native species' young.
Explanation:
Schizocoelic development
The coelom is a fluid-filled body cavity, where the internal organs are suspended in. It is the cavity between the wall of the body and the digestive tract.
In the schizocoelic development of the embryo, the coelom, called the schizocoel, develops as a split in the mesoderm. The outer layer of the mesoderm attaches with the ectoderm to form a body's musculature, while the inner layer attaches with the endoderm to form the wall of the digestive tract.
This type of development is commonly found in annelids, arthropods, and mollusks.
