Golden eagles have adapted their behavior for living in temperate
grasslands by building their nests on the ground.
Temperate grassland is characterized by mainly grasses and very few
trees. Animals like the Golden eagle who build their nests on tall trees are
able to adapt to the absence of these types of trees in the grasslands by
building their nests in the ground.
They live in in pairs in the temperate grasslands to efficiently guard the
nest and hunt animals for their survival.

Answer:
d. ATP is present and the intracellular Ca2+Ca2+ concentration is high.
Explanation:
Myosins are motor proteins that plays a major role in muscle contraction. They depend on ATP and responsible for motility in actin-based substances. Skeletal muscle is composed of myosin and actin fibers. Each myosin thick filament is surrounded by actin thin filaments, and each thin filament is surrounded by thick filaments. There exists a strong attraction between the myosin head and the myosin-binding site of actin which binds them spontaneously. This bond is aided by the presence of ATP and the high concentration of intracellular Ca2+. The myosin protein undergoes a change in its shape.
Fibroblasts, cells found in the connective tissues of the body, make up the hypodermis. These produce collagen proteins, which aid in preserving the body's structural foundation.
- The body's bottom layer of skin is called the hypodermis. It serves a variety of crucial roles, including energy storage, tying the muscles and bones beneath the skin's dermis layer to one another, keeping the body warm in a variety of temperatures, and guarding against injury-related harm.
- The hypodermis shrinks with ageing, the skin begins to sag, and the skin is more susceptible to damage and injury.
