Explanation:
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.
Which statement describes a difference between the lower mantle and oceanic crust? O The lower mantle is closer to Earth's surface than oceanic crust is. O The lower mantle is found closer to sea level than oceanic crust is. O The lower mantle experiences more pressure than oceaníc crust does. The lower mantle has a more tarry consistency than oceanic crust does.
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.
What are the lower mantle and an oceanic crust?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.

someone help me with this question.
Choose one carbon sink and explain how the carbon gets out of it. *
Someone please help me
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.

How does the ocean control weather and climate?
Answer:
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.

Which of the following explains why carnivores have simpler stomachs than herbivores?
o Meat is easier to digest than plant materials.
o Meat-eaters require fewer calories than plant-eaters.
O Herbivores are able to absorb nutrients more efficiently.
o Carnivores are more physiologically advanced than herbivores.
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.

The purpose of cellular respiration is to convert the energy stored in glucose to ATP.
Answer:
True
Explanation:
In your body, glucose is the form of energy that is carried in your blood and taken up by each of your trillions of cells. Cells do cellular respiration to extract energy from the bonds of glucose and other food molecules. Cells can store the extracted energy in the form of ATP

How does the structure of an amino acid relate to its function in cellular processes?
Explanation:
Protein function is directly related to the structure of that protein. A protein's specific shape determines its function. If the three-dimensional structure of the protein is altered because of a change in the structure of the amino acids, the protein becomes denatured and does not perform its function as expected.☺A person is admited into the hospital an unknown ailment.

A track team captain thinks that eating breakfast and having a good night's sleep may affect the team's performance.
The track team decides to test if eating breakfast makes a difference in how fast they can run one mile.
They decide to split the team into two groups. One group eats breakfast two hours before running and the other group does not eat breakfast. The students also make a rule that both groups have to get a good night's sleep before they run. Is this rule necessary?
A. Yes, because the rule allows the team to only test one variable at a time, keeping everything else a constant.
B. No, because they can judge the effect of having breakfast even if the students do not get enough sleep.
C. No, because they can judge the effect of having breakfast only if some students do not get enough sleep.
D. Yes, because they can judge the effect of both breakfast and sleep if all students get enough sleep.

How is a cell's cytoskeleton like the girders and
beams of a warehouse?
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.

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
