The disappearance of the deer indicates A. Intraspecific Competition
The answer is, How fast distant galaxies are moving away from us
Answer: It is because it makes it more efficient to study organisms.
Explanation: Biologist classify organisms by considering similarities between them. The organisms which have closely related characteristics are placed in a separate domains by biologists. Domains are further divided into 6 Kingdoms. According to modern classification system, domain is largest unit of biological classification.
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.

Adipose store fats which are potential source of energy.
Cartilage is incapable of extensive repair after severe damage.
The bony matrix can undergo repair and regrowth.
Plasma is the portion of blood that act as the matrix for this tissue type.
Plasma is the fluid component of blood in which the erythrocytes, lymphocytes and thrombocytes lie.
