Answer:

The three basic items to make an electromagnet are a source of current, conducting wire, and a metallic core. Electromagnetic is a type of magnet which is formed with the help of electricity.

When the current is allowed to pass through the wire and the metallic core, the magnetic field is generated around the metallic core and when the current is turned off, the metallic core losses the property of magnetism.

Alecsey [184]

Answer:

B) cytoplasmic streaming in hyphae

Explanation:

Fungal mycelium refers to the branched vegetative structure of the fungi which is formed by the growth of the hyphae. The hyphae contain three zones of growth: the apical, subapical and zone of vacuolation.

The hyphae grow in the apical region which forms a branched structure in which the cytoplasm continuously moves between the hyphae at the point of fusion towards the growing tip. This movement of the cytoplasm towards the growing tip is known as "cytoplasmic streaming".

This streaming of cytoplasm is responsible for the formation of a zone of vacuolation and the mycelium is formed.

Thus, Option-B is the correct answer.

The growing tip eventually gives rise to a branch. This is the beginning of the branched mycelium. Growing tips that come in contact with neighbouring hyphae often fuse with them to form a hyphal net. In such a vigorously growing system, the cytoplasm is in constant motion, streaming toward the growing tips. Eventually, the older hyphae become highly vacuolated and may be stripped of most of their cytoplasm.

Marianne is comparing two animals: a fruit fly and a fruit bat. She asks, "Do a fruit fly and a fruit bat share a common ancesto
Sonja [21]

The answer is; YES

All organisms share one common ancestor in the beginning of life. Different species have branched at different times from common ancestors hence he evolutionary tree looks like tree called a cladogram. The nodes represent the common ancestry while branches depict divergence. Therefore even fruit flies and the fruit bats even though they do not belong to the same species shared a common ancestor at one time in history.
