Describe the basic particle from which all elements are made

Answer : The correct option is, (B)

Explanation :

According to the reactivity series of the elements, a chemical reaction occurs when the most reactive element displace the least reactive element and form more stable products as compared to the reactants.

Option A reaction :

In this, no reaction will occur because zinc is less reactive metal as compared to aluminium. So, zinc will not displace the aluminium.

Option B reaction :

In this, the reaction will occur because sodium is more reactive metal as compared to calcium. So, sodium will displace the calcium easily.

Option C reaction :

In this, no reaction will occur because hydrogen is less reactive metal as compared to magnesium. So, hydrogen will not displace the magnesium.

Option D reaction :

In this, no reaction will occur because calcium is less reactive metal as compared to barium. So, calcium will not displace the barium.

Option E reaction :

In this, no reaction will occur because barium is less reactive metal as compared to lithium. So, barium will not displace the lithium.

Hence, the option B reaction will form products that are more stable than the reactants.

The reactivity series of the elements are shown below.

Answer:

got it correct

Explanation:

In multicellular organisms, the body is a system of multiple interacting subsystems. These subsystems are groups of cells that work together to form tissues and organs that are specialized for particular body functions.

Final answer:

The human body is a system of interacting subsystems composed of specialized cells and tissues, each performing a specific function. These subsystems, such as the circulatory and digestive systems, cooperate to maintain overall health and homeostasis.

Explanation:

The body is a system of interacting subsystems composed of a group of specialized cells and tissues. This is because each subsystem or organ system consists of particular types of cells and tissues that carry out specific functions. For instance, the circulatory system, made up of the heart, blood vessels, and blood cells, transports nutrients and oxygen throughout the body. The digestive system, including the stomach, small and large intestines, and other components, breaks down food and absorbs nutrients. These subsystems interact with each other to maintain the body's overall homeostasis and good health.

Not sure what the question is, but a standard sodium atom has 11 protons, 11 electrons, and 12 neutrons with an atomic mass of 23. A sodium atom with a mass number of 24 probably has 13 neutrons.
