Help!! Why do geologists radioactive/carbon dating determine absolute age? (i need this quickly!)
Answers
Absolute dating methods determine how much time has passed since rocks formed by measuring the radioactive decay of isotopes or the effects of radiation on the crystal structure of minerals. Paleomagnetism measures the ancient orientation of the Earth's magnetic field to help determine the age of rocks.

Astronauts on a spaceship in outer space notice their instruments detect energy from the Sun. Which of the following provides evidence that the Sun’s energy is moving through outer space?
A. Molecular collisions of visible light and infrared radiation
B. Electromagnetic radiation in the form of radio waves
C. Electromagnetic radiation in the form of matter
D. Molecular collisions of gas atoms
Answers
The statement that provides evidence that the Sun’s energy is moving through outer space is electromagnetic radiation in the form of radio waves.
What do you mean by Radio waves?Radio waves may be defined as electromagnetic waves enclosing a wavelength between 1 millimeter and 30,000 meters, or a frequency between 10 kilohertz and 300,000 megahertz. These waves are used in radio, television, and satellite communications.
The Sun's energy consists of UV radiations but these radiations are not consumed by radio waves, resulting in the consumption of electromagnetic radiation on the Earth's surface.
Therefore, the statement that provides evidence that the Sun’s energy is moving through outer space is electromagnetic radiation in the form of radio waves.

How would you demonstrate that all cells come from preexisting cells
Answers
Answer: The generally accepted parts of modern cell theory include: ... All living cells arise from pre-existing cells by division. The cell is the fundamental unit of structure and function in all living organisms. The activity of an organism depends on the total activity of independent cells.
Explanation:
To demonstrate that all cells come from pre-existing cells, you should: Observe a bacterium performing binary fission to form clones of itself.
A cell can be defined as the basic functional, structural and smallest unit of life which is found in all living organisms.
According to cell theory, the following statements are true about cells;
All living organisms comprises small structural units called cells.A cell is the fundamental (basic), functional unit of life.Every living organism is made up of one or more cells: unicellular or multicellular.All cells are produced from existing (other) cells i.e pre-existing cells produce new ones through a process called cell division.Binary fission is an asexual reproduction wherein the body of a prokaryotic organism such as bacterium, is divided into two (2) new identical bodies.
In order to demonstrate that all cells come from pre-existing cells, you should observe a bacterium performing binary fission (dividing) to form clones of itself.
In conclusion, the chromosome (pre-existing cell) of a bacterium containing deoxyribonucleic acid (DNA) and associated proteins replicates and then divides in half to form clones of itself (identical daughter cells).

What is the use of reverse transcriptase?Reverse transcriptase enzyme has been generally used by the retrovirus for their genome replication. This enzyme has been discovered by the Howard tenim.
Reverse transcriptase enzyme generates the complementary DNA from the mRNA template by the process of reverse transcription. The presence of RNase H, RNA-dependent DNA polymerase and DNA-dependent DNA polymerase activity enable the enzyme to convert the mRNA into DNA.
The position of the mRNA is to carry protein facts from the DNA in a cell's nucleus to the cellular's cytoplasm (watery interior), where the protein-making machinery reads the mRNA sequence and translates every three-base codon into its corresponding amino acid in a growing protein chain.
Therefore, The mRNA sequence will best match the section of DNA shown below is C-U-A-G-G-A. Thus, option C is correct.

What is cell?All living organisms are made up of cells, which are the basic building components. There are billions of cells in the human body. They support the body's structure, absorb nutrients from meals, transform those nutrients to energy, and perform specific activities. Cells also carry the body's genetic material and have the ability to replicate themselves.A cell is a cytoplasmic mass that is outwardly bound by a cell membrane. Cells are the smallest structural units of living matter and make up all living things. They are usually tiny in size. Most cells have one or more nuclei, as well as additional organelles that perform various functions.In unicellular and multicellular organisms, cells act differently. A unicellular creature relies on only one cell to conduct all of its duties. A multicellular organism contains cells that specialize in distinct roles and work together to maintain the organism.Hence the correct option is B.

which of the following?

Odigest metabolic wastes in the organelle
O produce ATP during cellular respiration

Answers
Answer:
convert solar energy to chemical
Explanation:
the mitochondria is the power house of the cell
The folds greatly increase the membrane's surface area. This improves the ability of the mitochondrion to produce ATP during cellular respiration. Thus, the correct option is C.
What is Cellular respiration?Cellular respiration is the process through which biological fuels are oxidized in the presence of an inorganic electron acceptor in the cell such as oxygen to produce large amounts of energy, to drive the bulk production of ATP (Adenosine triphosphate) in the mitochondria.
A large number of folds are present in the mitochondrial membrane to increase the capacity of the mitochondrion to synthesize ATP molecules, the inner membrane of the mitochondria is folded to form cristae in the membrane. These folds allow a much greater amount of electron transport chain (ETC) enzymes and ATP synthase to be packed into the mitochondrion membrane.
Therefore, the correct option is C.

B) Explain how ATP and ADP act as allosteric regulators of enzymes that are responsible for ATP production, and how that is an example of feedback inhibition.
C) What is feedback inhibition? How is the ATP generating pathway discussed in part B an example of feedback inhibition?
Answers
Answer: B)
B) ADP can act as an allosteric activator by slowing the breakdown of fuel molecules if sufficient energy is in the cell. APT can act as an inhibitor by storing resources in more complex molecules. That is an example of feedback inhibitor because when the end product of the substrate is finished, it can bind to the allosteric site, which will result in the enzymes active site no longer being able to bind with the new substrates. And that is responsible for ATP production because That “stops” the enzyme from making more than necessary and thus wasting chemical resources.
C) Feedback inhibition is a method of metabolic control in which the need of the product of a metabolic that way acts as an inhibitor of an enzyme within that pathway. The APT generating path is an example of feedback inhibition because it controls the amount needed of the product and acts as an inhibitor of the enzyme in the anabolic pathway.

In which Colorado Rockies scenario was there more erosion? Why was there more erosion in the scenario?
Answers
Answer:
There was more erosion in the Colorado Rockies scenario where there was steady rain compared to the scenario in the same area where there was only a drizzle. There is more erosion because the steady rain increased the volume of the river more than the drizzle did. Because there was more water added to the river, the river flowed faster. The faster a river flows, the more sediments it transports or erodes.
