I'm not sure on how to help with most of those, however I can try my best with a few parts.
The Hadean Eon
The first Eon of Time is the Hadean Eon. The Hadean Eon is the oldest interval of Time and is dated from 4,600 Million Years Ago to 3,900 Million Years Ago. No rock record dating from the Hadean Eon is known on Earth with the exception of the 3.96 Billion Year old rocks found in Canada's Northwest Territories. Although, rocks on other planets in the Solar System were possibly deposited during the Hadean Eon. Earth's earliest known life forms are found in rocks dating from the Archean Eon.
Lasted around about 700 million years
The Archean Eon
The oldest rocks known on Earth were deposited during the Archean Eon which is dated from 3,900 Million Years Ago to 2,500 Million Years Ago. The Archean Eon is also referred to as the Archaeozoic Eon. Sedimentary rock deposited in the oceans during the Archean Eon contains microscopic life-forms that have bacterial characteristics. These organisms were among the only living things on Earth for over one billion years. Stromatolites, formed by colonies of photosynthesizing bacteria known as cyanobacteria (blue-green algae) lived in shallow waters. In the Archean Eon, Earth's atmosphere was composed of methane, ammonia, hydrogen, and carbon monoxide, which would be unbreathable by living organisms today. The extensive colonies of photosynthesizing cyanobacteria released oxygen into the atmosphere, beginning a process that eventually resulted in a breathable atmosphere and impacted living things in future Eons. The climate and weather in the Archean Eon were very hot and wet. The oceans were also very warm. Extensive worldwide volcanic eruptions ejected volcanic ash and dust into the atmosphere causing violent lightning storms and continual rain.
Lasted around 1.5 billion years (I'm unsure about this one)
The Proterozoic Eon
Rocks deposited during the Proterozoic Eon include evidence of multicelled organisms. The Proterozoic Eon was from 2,500 Million Years Ago to 540 Million Years Ago. The stromatolites remained common in the shallow waters of the Proterozoic Eon oceans, however, many other living things were present such as archaea that lived in extreme habitats where the water was very hot and extremely salty. By the end of the Proterozoic Eon, eukaryotes, cells that have a nucleus, appeared and were the ancestors of all modern living things. One of the first extinctions occurred in the Proterozoic Eon when oxygen accumulated in the atmosphere and caused those bacteria that required the atmospheric conditions of the Archean Eon to die. The Proterozoic Eon also experienced two ice ages, when polar ice became at least a kilometer deep and covered an area extending to the equator.
Lasted around 1.9 billion years
The Phanerozoic Eon
The Phanerozoic Eon began 540 Million Years Ago and continues into the Present. The Rocks deposited during the Phanerozoic Eon contain evidence of fossilized hard body parts of modern living things.
Still ongoing
Eon is the longest period of measuring time which is roughly equal to 1 billion years.
What is geological time?The lengthy period of time that the Earth's geologic history takes up is known as geologic time.
Formal geologic time started around the beginning of the Archean Eon, between 4.0 and 2.5 billion years ago, and it is still going on today.
The Hadean Eon, which is an unstructured period that runs from around 4.6 billion years ago, which corresponds to Earth's beginning creation, to 4.0 billion years ago, is also frequently included in modern geologic time scales.
The period of Earth's history that is reflected by and preserved in the planet's rock layers is known as geologic time.
Events in Earth's history are "calendared" according to the geologic time scale.
It divides all of the time into designated units of abstract time termed eons, eras, periods, epochs, and ages, in decreasing order of duration.
Those geological timescale units are counted according to stratigraphy, the correlation, and the categorization of rock layers.
Therefore, eon is the longest period of measuring time which is roughly equal to 1 billion years.

Describe three examples of the results of scientific inquiry
Answer: develop new materials and technology, discover new objects, or find answers to questions.
Explanation:
Consider the feeback loop that occurs when you pull your hand away from something hot. How does this reflex help to maintain homeostasis?
Answer:
This reflex helps by not causing the temperature in the part of your body that is touching the hot object to get to hot, which saves you from a very painful burn
Explanation:
Answer:
This reaction protects you from a burning burn by preventing the temperature in the part of your body that is touching the hot object from rising too far.
Explanation:

Where does water enter a plant?
Answer:
by roots
Explanation:
The significant way for water development into plants is from soil to roots. Water enters close to the tip of a developing root, a similar locale where root hairs develop. The outside of the root hairs should be in close contact with the dirt to get to soil water.
Answer: Water enters the plants roots.
Explanation: water enters near the top of the growing root. Hope it helps!

What are the functions of DNA?Deoxyribonucleic acid is a polymer composed of two polynucleotide chains that coil around each other to form a double helix. The polymer carries genetic instructions for the development, functioning, growth.
Nucleic acids, deoxyribonucleic acid (DNA) and ribonucleic acid (RNA), carry genetic information which is read in cells to make the RNA and proteins by which living things function.
Three major forms of DNA are double stranded and connected by interactions between complementary base pairs. These are terms A-form, B-form,and Z-form DNA.
