Answer:

Answer:  B. The release of calcium ions causes myosin and actin to attach to each other. This statement best describes a cause and it's effects that occur during the process of muscle contraction.

Muscle contraction can be explained by sliding filament theory.  

1. Activation of muscles: the motor nerve generates an impulse to transfer signals from neurons to neuromuscular junction. This stimulates sarcoplasmic reticulum to release calcium into the muscle cells.

2.Contraction of muscles:  calcium in the muscle cells binds with troponin causes actin and myosin to bind. Actin and myosin in the muscle binds and contract by utilizing ATP as a source of energy.

Balance the following chemical equation. CCl4 → C + Cl
andrezito [222]

Answer: The balanced reaction is CCl4 → C + 4Cl

A balanced chemical equation is the one, which contains equal number of atoms corresponding to each element participating in the reaction and having same charge for the reactants and the products.

In the given reaction CCl4 → C + Cl, the number of chloride atoms are imbalanced on both sides as it is four on the reactant side while it is one on the product side.

Thus, the balanced reaction for this is-

CCl4 → C + 4Cl

vodomira [7]

Answer: <u>At the end of interphase comes the mitotic phase, which is made up of mitosis and cytokinesis and leads to the formation of two daughter cells.</u>

Explanation:

This is when the cell grows and copies its DNA before moving into mitosis. During mitosis, chromosomes will align, separate, and move into new daughter cells. ... At the end of interphase comes the mitotic phase, which is made up of mitosis and cytokinesis and leads to the formation of two daughter cells.

________ waves need to interact with particles of either a solid, liquid, or gas to travel.
mixer [17]

Mechanical waves waves need to interact with particles of either a solid, liquid, or gas to travel.

<u>Explanation:</u>

In the world, the dispersal of energy is under the control of two important waves called electromagnetic waves and mechanical waves. Waves in water and sound waves in air are two instances of mechanical waves. Mechanical waves are brought about by an unsettling influence or vibration in particles of either a solid, liquid, or gas to travel.

Water waves are formed by vibrations in a fluid and sound waves are shaped by vibrations in a gas (air). These mechanical waves travel through a medium by making the atoms to interact with one another.
