Answer:

Endoplasmic reticulum.

Explanation:

Second messengers are known as intracellular signaling molecules released from the cell in response to exposure to extracellular signaling molecules. Second messenger activate physiological changes at a cellular level, for example proliferation, migration, differentiation, survival, and apoptosis.

Calcium ions are hydrophilic, water-soluble molecules. They are present in intracellular component know as endoplasmic reticulum and quickly released when needed. They are necessary for many important functions including fertilization, muscle contractions, and neurotransmitter release.

What are The advantages of using scientific procedures in doing science experiments?

Studentka2010 [4]

Answer:

Doing experiments by scientific procedures is advantageous and helpful.

Explanation:

The scientific procedure should be followed while performing a experiment as it has many advantages like:

Working in safe environment: Performing a experiment by scientific procedure ensures the safety of the experimenter.

It reduces the chances of mistakes: The proper availability of the scientific equipment helps in reduction of the chances of the mistakes.

A sequence of steps is followed: A proper sequence of steps is followed to perform a experiment step by step. Performing experiment without scientific procedure may cause the experimenter to forgot a step.

More Accuracy: The readings of the experiment is more accurate by doing experiment by scientifically.

Chemical changes can be observed: The physical and chemical changes can be observed and can be measured by the lab equipment to perform more accurately.

less chance of risks: Performing in the safe scientific environment and using proper safety equipment reduces the chances of risks to the experimenter.
