Oceans formed when rainwater filled basins 3.8 billion years ago. Physical erosion runs into the ocean dissolving minerals like salt as they go. Minerals leave salt in the ocean, which is why the ocean is dissolved.
Salinity has crystals, so the ocean is thicker and getting more or less salty. Salinity makes water full of minerals and contributes to currents.
How oceans are formed?The oceans formed billions of years ago due to the condensation of water into rain which significantly filled the basins that ultimately direct the formation of the oceans. Apart from this, the continuous degassing of the interior surface of the earth is also responsible for this fact.
According to the context of this question, the salinity of the oceans depends on the number of minerals dissolved in it which contributes to the development of currents.

Which aspect of this experiment should be kept the same in all the other tests? Some students want to test different soils to find out which ones absorb heat the fastest. For the first test, they put 500 grams of sand in a beaker and put a thermometer in the sand. Which aspect of this experiment should be kept the same in all the other tests?
Answer:
Weight of the soil (500g)
Explanation:
According to this question, some students are conducting an experiment in order to find out which of the different soils used absorb heat the fastest. For the first test, they put 500 grams of SAND in a beaker and put a thermometer in the sand.
In an experiment, the variables that must be kept constant for all the groups is called the CONSTANT OR CONTROLLED VARIABLE. This is done in order not to influence the outcome of the experiment. In this case, the weight (500g) of the soil should be kept the same for all other tests.
This means that for the remaining soil being tested, 500g of each type of soil should be used.

What molecules will carry the electrons to the electron transport chain?
Answer:
electron and nuetrons
The molecules NADH and FADH₂ will carry the electrons to the electron transport chain.
These electron carrier molecules (NADH and FADH₂) are produced during the breakdown of glucose and other energy-rich molecules in the preceding steps of cellular respiration. They carry the high-energy electrons derived from these molecules to the electron transport chain, which is embedded in the inner mitochondrial membrane in eukaryotic cells.
The electrons passed through the electron transport chain ultimately combine with molecular oxygen to form water, which is the final electron acceptor in the chain.

How can you account for the great number, size, and complexity of organic compounds?
Answer:
Explanation:
"how can you account for the great number, size, and complexity of organic compounds? carbon can bond with so many elements. It can bond with itself and form long chains. Also, all macromoleculse are composed of C,H,N, and O."
Organic compounds number in the millions, far outnumbering inorganic compounds. The reason for this is due to the uniqueness of carbon's structure and bonding abilities.
What are organic compounds?Any of a wide range of chemical compounds in which one or more carbon atoms are covalently linked to atoms of other elements, most commonly hydrogen, oxygen, or nitrogen.
Carbides, carbonates, and cyanides are among the few carbon-containing compounds that are not classified as organic.
Organic compounds in the body include carbohydrates, lipids (including phospholipids), proteins, nucleotides, and nucleic acids.
Water (H2O), bimolecular oxygen (O2), carbon dioxide (CO2), and some acids, bases, and salts are the most important inorganic compounds. The human body is 60-75% water.
Organic compounds outnumber inorganic compounds by orders of magnitude. This is because of the uniqueness of carbon's structure and bonding abilities.
Thus, this way, one can account for the great number, size, and complexity of organic compounds.

Krebs cycle
Answer:
D. Krebs Cycle
Explanation:
Hope this helped.
The answer to this question is Krebs Cycle.
Krebs cycle. A series of chemical reactions that occur in most aerobic organisms and are part of the process of aerobic cell metabolism, by which glucose and other molecules are broken down in the presence of oxygen into carbon dioxide and water to release chemical energy in the form of ATP.
Overview of the Krebs or citric acid cycle, which is a series of reactions that takes in acetyl CoA and produces carbon dioxide, NADH, FADH2, and ATP or GTP.
The Krebs cycle itself actually begins when acetyl-CoA combines with a four-carbon molecule called OAA (oxaloacetate). This produces citric acid, which has six carbon atoms. This is why the Krebs cycle is also called the citric acid cycle.May 15, 2020
two specific examples of radioactive isotopes being used as “spies”
Answer:
Carbon-14 in photosynthesis and Florbetapir (18F) in PIB of Alzheimer's disease.
Explanation:
These radioactive isotopes known as the biological spies as they tell or mark the presence or activity of a particular atom to the scientists in living beings.
For instance,
1. the process of photosynthesis can be understood by observing the radioactive isotope Carbon-14 from taking the carbon dioxide to the generation of glucose molecule by molecule process.
2. A protein that is deposited in people with Alzheimer's disease, called beta-amyloid. It is bind with another protein known as PIB, which contains Florbetapir (18F) a radioactive isotope. It gives an idea about the location of PIB and deposits in amyloid to try to eliminate the protein deposits and check the effect of medication.

If the DNA sequence was a AGC what would the mRNA sequence be?
Answer:
DNA utilizes four bases, adenine (A), guanine (G), cytosine (C), and thymine (T), in its code. RNA also uses four bases. However, instead of using 'T' as DNA does, it uses uracil (U). Therefore, if your DNA sequence is 3' T C G T T C A G T 5', the mRNA sequence would be 5' A G C A A G U C A 3'.
