Explanation:

The ocean currents regulate global climate, helping to counteract the uneven distribution of solar radiation reaching Earth's surface.

Ocean water is constantly evaporating, increasing the temperature and humidity of the surrounding air to form rain and storms that are then carried by trade winds.

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

Explanation:

The difference between the lower mantle and the oceanic crust is first their respective locations, pressure and temperature-- the pressure and temperature increases with depth in the earth this the mantle is more hot and under great pressure than the crust. hope this helps

The statement describes the main difference between the lower mantle and an oceanic crust is that the lower mantle experiences more pressure than the oceanic crust. Thus option C is correct.  

The lower mantle is the middle layer of the earth which lies in between the crust and the core. This is the middle layer of the earth in which the temp and pressure are so high because of the absence of air. The oceanic crust is the uppermost layer of the earth's crust in which marine plants grow.

The main difference between these two is that the mantle crust experiences more pressure than the oceanic crust because it is present in more depth. As we go in depth of the earth the temp and pressure arise because of the unavailability of oxygen.

So by reading this data the correct statement which exactly describes the difference between the mantle and the oceanic crust is statement C.

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.

Cellular Stomach

Explanation:

Containing acid and several types of digestive enzymes, lysosomes digest unwanted organelles in a process termed autophagy, from the Greek words for “self” and “eat.” The multipurpose lysosome also processes proteins, bacteria and other “food” the cell has engulfed.

Answer:

Meat is easier to digest than plant materials

Explanation:

Plant material, such as cellulose, is often tough and challenging to digest. This would mean having complex stomaches would be a favorable digestive system for all herbivores. Carnivores do not need such intricate stomachs, as meat is easier to digest.

Cytoskeleton helps the cells to maintain its shape and size, due to this they are like the girdles and beams of a warehouse.  

• A composition within the cell, which helps the cell to maintain their internal organization and shape is known as the cytoskeleton.  

• It also provides mechanical support, which allows the cells to perform essential activities like movement and division.  

• In the eukaryotes, the cytoskeleton within the cell is formed of filamentous proteins.  

• The three prime classes of elements, which differ in size and in composition of protein forms the cytoskeletons.  

• These are microtubules, actin filaments, and intermediate filaments.  

Thus, due to the properties of the cytoskeleton, they can be considered as the girders and beams of a warehouse.

Answer:

Option B: Molecule 2

Explanation:

'Equilibrium of a molecule inside and outside a cell' means that there are similar numbers of that molecule on the inside and the outside. (hence 'equilibrium')

The number of each molecule is as follows:

Molecule 1 - Inside: 3, Outside: 5

Molecule 2 - Inside: 2, Outside: 3

Molecule 3 - Inside: 1, Outside: 5

Molecule 4 - Inside: 7, Outside: 4

Therefore the correct option is option b. 2

This is because the number of molecules inside the cell and outside the cell are the closest together, most similar out of all the molecules.
