Biology
1 answer:
Margaret [11]3 years ago
8 0

Answer:

The cell's shape depends in part on the structure and composition of the extracellular matrix.

The size that the cell grows to depends in part on the polysaccharides in the extracellular matrix.

Explanation:

The extracellular is a suspension of macromolecules that supports the local tissue growth and  maintain  organs. The extracellular matrix directs the morphology of a tissue.

The extracellular matrix  stores  cellular growth factors, which are released locally based on the physiological needs of the local tissue.

The extracellular matrix  transduce signals into cells, which regulate cellular functions such as  growth, proliferation, migration, differentiation, etc.

after a power stroke, the myosin head must detach from acting before another powerstroke can occur. what causes
kompoz [17]

The myosin head separates from actin as a result of ATP binding. The intrinsic ATPase activity of myosin then transforms ATP into ADP and Pi. The myosin head's angle is altered into a cocked state by the energy generated during ATP hydrolysis. The myosin head is now ready to move in the future.

The myosin protein is in a high-energy conformation when the head is cocked. At the end of the power stroke, the myosin head is in a low-energy position because this energy has been used up during the power stroke. ADP is released following the power stroke, but the cross-bridge is still there and actin and myosin are joined together.

Since ATP is readily available, the cross-bridge cycle can repeat, and muscular contraction can go on as long as ATP is there.

How will the level of carbon in the atmosphere change if humans do nothing to reduce their impact on the carbon cycle?
kaheart [24]

Answer:

Option (4)

Explanation:

Carbon forms the basin element for the existence of life. It is present in the atmosphere in the form of CO₂, which is one of the major green house gas. It plays an important role in the carbon cycle.

The increase in the concentration of carbon in the atmosphere can lead to the global rise in the temperature. It can lead to global warming. The amount of carbon in the atmosphere has been rising continuously, right after the industrial revolution.

The carbon is mainly emitted from the heavy industries and factories, vehicles, burning up of fossil fuels. It also increased due to the increasing absorption of solar radiation.

This emission of carbon if not controlled by the humans, then the concentration of carbon in the atmosphere will abruptly increase after some decades.

Thus, the correct answer is option (4).
