Answer:
<h2>Actin and myosin.</h2>
Explanation:
The cells that allow your bones to move, the movement of thick (myosin) and thin (actin) filaments during contraction
.
During a contraction thick and thin filaments do not shorten but increase their overlap of each other.
Thin filaments slide past thick filaments extending more deeply into the A band.
The I bands and H bands decrease in lenght as Z discs are come closer together
.
Sarcomere represents area between two Z disc, so the sarcomere gets smaller during a contraction
.
Answer:
Water uses adhesive forces that allow it to stick to certain surfaces such as glass.
Explanation:
When the angle between vertical direction and the glass wall is small, surface tension is stronger and the component of gravity perpendicular to the glass wall is small. The result of this causes water to stick to the side of a glass.
Hope this helps!
"The solubility of gases decreases as temperature rises" statements about trends in solubility is accurate.
<u>Option: D</u>
<u>Explanation:</u>
A substance's solubility is the quantity of that component that is needed at a defined degree of temperature to produce a saturated solution in any set quantity of solvent. Some compounds like hydrochloric acid, ammonia, etc have solubility that reduces with rising temperature. They are both standard-pressure gases.
When heating a solvent with a gas absorbed in it, both the solvent and the solute spike in the kinetic energy.When the gaseous solute's kinetic energy rises, the molecules have a higher propensity to overcome the solvent molecules' connection and migrate to the gas phase. Thus, a gas's solubility reduces with rising temperature.
