Explain how the geologic time scale is used to organize Earth’s history.
Think about how the geologic time scale was created and how it is divided. Then answer the following questions.
How did scientists from the geologic time scale?
How is this scale organized?
What processes changed the Earth's environment during Precambrian time?
Answer:
The first principle you need to understand about geologic time is that the laws of nature are always the same. This means that the laws describing how things work are the same today as they were billions of years ago. For example, water freezes at 0°C. This law has always been true and always will be true. Knowing the natural laws helps you think about Earth’s past, because it gives you clues about how things happened very long ago. It means that we can use present-day processes to interpret the past. Imagine you find fossils of sea animals in a rock. The laws of nature say that sea animals must live in the sea. That law has never changed, so the rock must have formed near the sea. The rock may be millions of years old, but the fossils in it are a clue for us today about how it formed.
Now imagine that you find that same rock with fossils of a sea animal in a place that is very dry and nowhere near the sea. How could that be? Remember that the laws of nature never change. Therefore, the fossil means that the rock definitely formed by the sea. This tells you that even though the area is now dry, it must have once been underwater. Clues like this have helped scientists learn that Earth’s surface features have changed many times. Spots that were once covered by warm seas may now be cool and dry. Places that now have tall mountains may have once been low, flat ground. These kinds of changes take place over many millions of years, but they are still slowly going on today. The place where you live right now may look very different in the far future.
The first principle you need to understand about geologic time is that the laws of nature are always the same.
What is the Time scale?Water, for instance, freezes at 0°C. This rule has held and will continue to hold forever.
Understanding natural principles facilitate historical thinking because it provides hints about how things were very long ago. It implies that we can interpret the past using current methods.
The rock must have formed close to the sea because this law has never changed.
Therefore, The first principle you need to understand about geologic time is that the laws of nature are always the same.

Explanation:
which part of the nucleotide contains the coded information for an organism's
traits?
DNA, the Code of Life
DNA is a complex, long-chained molecule that encodes the genetic characteristics of a living organism.
Bases are the part of DNA that stores information and gives DNA the ability to encode phenotype, a person's visible traits. Adenine and guanine are purine bases. These are structures composed of a 5-sided and 6-sided ring.

A) A river wears away the land creating a canyon.
B) Over time a mountains top becomes less jagged and more rounded.
C) A volcano erupts and lava flows down its sides.
D) Silt is deposited at the mouth of a river.
Answer:
C, D.
Explanation:
C: The flowing lava creates extra rock. For example, entire islands are formed via this process of volcanos erupting, lava cooling, repeat.
D: Silt from erosion (erosion itself is considered destructive, but the resulting silt can turn into something constructive.) can build up entire mounds or mountains over time.

What two air pollutants are associated with the formation of acid rain?
Answer:
Acid rain is caused by a chemical reaction that begins when compounds like sulfur dioxide and nitrogen oxides are released into the air. These substances can rise very high into the atmosphere, where they mix and react with water, oxygen, and other chemicals to form more acidic pollutants, known as acid rain.

Human p53 is a tumor-suppressor gene located on chromosome 17. The function of this gene is to prevent cells with damaged DNA from undergoing mitosis. What would most likely result if there were a mutation that decreased the function of the p53 gene?
The answer is “Germs cells would undergo only one meiotic division.
Explanation:
I remember learning this in my biology class
Single amino acid changes in p53 caused by TP53 gene mutations make the protein less functional. Without p53, cell proliferation is not efficiently controlled, and DNA damage can build up in cells.
How p53 gene is important?Such cells might continue to divide uncontrollably, which would promote the development of tumors. By stopping the cell cycle to give the repair mechanisms time to restore genomic stability, p53 plays a significant function as a DNA repair facilitator.
Additionally, p53 adopted a variety of roles to directly influence the operation of different DNA-repair mechanisms.
Cancer cells may develop and spread throughout the body as a result of mutations (changes) in the p53 gene.
Therefore, numerous cancer kinds and the genetic disorder Li-Fraumeni syndrome have both been linked to these alterations.

Match the term with its description. Match Term Definition Anaerobic respiration A) The production of energy without the presence of oxygen Pyruvate B) An organic molecule that occurs as an intermediate in many metabolic processes Aerobic respiration C) The chemical breakdown of a substance Fermentation D) The breakdown of food to create energy in the presence of oxygen
Answer:
The correct match of terms with their descriptions are -
A. anaerobic respiration
B. pyruvate
C. Fermentation
D. aerobic respiration.
Explanation:
Anaerobic respiration is the process that involves the production of energy from sugar or carbohydrate in absence of oxygen.
Pyruvate is the intermediate product or substance of the various metabolic process including cellular respiration.
The chemical breakdown of the sugars is known as fermentation. It takes place due to the enzymatic reaction to change in the organic substance.
An aerobic respiration occurs in most eukaryotic organism in order to get energy by the breakdown of sugar or food in presence of the oxygen
Students are asked to pair a plant structure to its physiological function as well as give evidence for why
that structure is important for the process they describe.
• Shantal: The cambium are important for photosynthesis because they allow water into the plant
which is needed as a reactant for photosynthesis.
• Jamil: The phloem is needed for cellular respiration as it transports the carbon dioxide to the leaves
in order to perform cellular respiration.
• Enrique: The guard cells are needed during food production because they regulate how much water
the plant retains or loses during glycolysis.
• Anne: The seeds of the plant are needed for reproductive purposes and they can be dispersed or
spread out over a large area.
Which student correctly described a plant structure, its physiological function, and gave appropriate
evidence?
O Shantal
O Jamil
O Enrique
O Anne
Answer:
Anne
Explanation:
The only student that correctly described a plant structure, its physiological functions, and gave appropriate evidence is Anne.
The seeds of plants are propagules and, depending on the kind of seed, can be dispersed over a large area from their parent plants.
The phloem of a plant is primarily concerned with the conduction of synthesized food around the body of the plant from the source of production. Hence, Jamil's description that the phloem is needed for cellular respiration as it transports the carbon dioxide to the leaves was inaccurate.
The guard cells control the rate of evapotranspiration of water from the plant but have nothing to do with the breakdown of glucose, also known as glycolysis. Thus, Enrique's assertion was also inaccurate.
