The mass of the atom is contained mainly in the nucleus itself. The nucleus is composed of a number of protons and neutrons which are positively charged and neutrally charged sub particle components. The nucleus are surrounded by electrons.

The mass of an atom is contained primarily in its NUCLEUS.
An atom is made up of three sub particles, which are proton, neutrons and electrons. The proton and the neutrons are located in the nucleus of the atom while the electron are located outside the nucleus where they move about in continuous motion around the nucleus. The proton and the neutrons, which are located in the nucleus have the same relative mass of 1, which has been estimated to be about 2,000 times bigger than that of the electron, which has a relative mass of 0.0005. This shows that, the mass of an atom is located primarily in its nucleus. <span />

Homeostasis: Response to Stimuli

likoan [24]

Answer:

3.)A person shivering when their body temperature is low.

7.)Ants moving within their mounds depending upon the time of day

1-A plant bending toward a light source.

.-Iguanas laying in the sunlight if their body temperature is low.

.-A unicellular organism beating microscopic hairs to escape a chemical pollutant in its environment

.-Birds migrating when seasons change.

The maintenance of relatively constant internal environment of an organism is called Homeostasis.It is an automatic regulations of the body systems and organs controlled by the brain and some receptors, specific for certain body fluctuations.E.g Thermoreceptors Chemoreceptors etc.

The fluctuations in the body internal systems must be controlled within a narrow limits, for existence of living organism.The brain receives inputs from the receptors, and the outputs from the brain ensures the homeostatic control.

The above examples are typical homeostatic responses by the organisms involved, because the inputs from the receptors send signals to the brain ,and the organisms responded to these with the example above.

docker41 [41]

The difference between the "Question" and the "Hypothesis" is that a hypothesis is what you believe is the answer to the question based off of limited evidence while the question is just a regular question e.x. (for question) "Why is the water moving to the south?"
then using whatever evidence they will have they would do a hypothesis e.x. (for hypothesis) I believe the water is moving south due to the wind coming down from the north... or due to a current.
