The sequence by which electrons travel downhill during aerobic respiration. The se sequence has NADH, oxygen chain of transportation of electron, food and NAD.
Respiration (both aerobic and anaerobic) begins with glycolysis in the cytoplasm of a cell;
1 glucose molecule (C₆H₁₂O₆) is converted into 2 molecules of pyruvate in a 10-step process, consuming 2 ATPs and yielding 4 ATPs;
Additionally, 2 NAD+ molecules are reduced to NADH molecules;
In aerobic respiration, each pyruvate molecule then goes through the link reaction, getting converted to acetyl co-A in the mitochondrial matrix, producing 1 CO₂ molecule and 1 reduced NADH molecule;
Acetyl co-A then enter the Krebs or tricarboxylic acid cycle (TCA) where 2 CO₂, 1 ATP, 3 NADH (by reduction of NAD+) and 1 FADH₂ molecules are produced;
The NADH and FADH₂ molecules produced are electron carriers required for the electron transport chain (ETC);
The electron transport chain consists of 4 proteins within the inner mitochondrial membrane which are involved in the production of ATP by oxidative phosphorylation;
The first protein (C1) is responsible for oxidising NADH to NAD+, releasing energy used to generate the proton motive force (PMF) by pumping the protons (H+ ions) into the intermembrane space and the electrons released are transferred to a ubiquinone molecule;
The second protein (C2) is responsible for oxidising FADH₂ to FADH, also releasing energy used to generate the proton motive force (PMF) and, similarly to C1, the electrons released are transferred to ubiquinone;
The third protein complex (C3) transfers the electrons from ubiquinone to cytochrome C;
Finally, cytochrome C transfers these electrons to the fourth complex (C4), where they combine with free protons in the matrix and O₂ to to produce H₂0;
The PMF is then harvested via an ATP synthase protein where H+ flood back into the mitochondrial matrix, and the energy released is used to generate ATP from ADP and Pi;
ATP is now ready for use for bodily processes requiring it.
What term describes the total mass of trees, shrubs, herbaceous plants, and grasses present in a given forest on a given day
The term best describes the mass of the above-ground vegetation in a given forest would be the standing crop.
The standing crop of a forest specifically refers to the mass of all the living plant materials present in the forest at a particular time ranging from the biggest of trees, shrubs, herbs, to the tiniest of grasses.
Standing crop is as opposed to biomass in that the latter refers to the total mass of organic materials from the living and dead plants derivable from the forest.

What can you infer about the position of the galaxies 100 million years
before this telescope photo was taken? How does this relate to the big bang
theory?
Although the picture for this question is not given, if we have the possibility to view galaxies from 100 million years ago and compare them to the photos we have today, we would see that their positions would be different.
Why would the position of the galaxies have changed?This has to do with the fact that the universe is always expanding.
The idea of an expanding universe means that galaxies are moving farther away all the time.
However, due to the effects of gravity, some galaxies pull each other in and form groups or clusters.
Therefore, due to the formation of galaxy groups or clusters, the position of galaxies may have changed in relation to others from outside its groups in the last 100 million years, while remaining the same relative to other galaxies in its local group.

What happens to the tides if the earth spinner fast??
Answer:
it would be a disaster
Explanation:
The centrifugal force would pull hundreds of feet of water toward the Earth's waistline.
Answer:
If the Earth were to spin faster, the tides would change because the fast speeds would increase stress; making tighter circles of convection. This would cause more natural disasters like hurricanes, cyclones, and tsunamis.

How might the interdependence of organisms in a specific habitat be
helped or harmed as a result of changes in the ecosystem over time?
Changes in an ecosystem may benefit one organism by removing predators while affecting the predator species negatively.
What is the effect of change in ecosystem over time on the interdependence of organisms in a specific habitat?Changes that occur in an ecosystem may occur as a result of natural or man-made causes.
Changes in an ecosystem may have positive or negative effects on the interdependence of organisms in a specific habitat.
For example in an aquatic habitat where certain species of fishes like sharks depends on smaller fishes like salmon to survive, if humans were to reduce the salmon population by overfishing, the sharks will be negatively affected as they may have to migrate to new hunting grounds.
However, some other fishes that are prey to shark may be able to grow more with the reduction on shark population in that area.
Therefore, changes in an ecosystem may benefit one organism by removing predators while affecting the predator species negatively.

Explain why sickle cell anaemia is persistent in the tropics yet it is lethal and these areas have high malaria Providence.
Sickle cell anemia is persistent in the tropics because those with sickle cell anemia cant contract the malaria virus because of the shape of their blood cells, and this is advantageous in the tropics where there are more malaria cases. So those with sickle cell anemia live to pass on their genes.

Answer:
2.25 m/s^2
Explanation:
Acceleration is the speed which you are increasing by per second. Therefore to find acceleration all you need to do is divide the change in velocity (4.5) by the time (2). Your units than become (m/s)/s or m/s^2.

I am almost certain it is A) a and d) but I need reassurance.
Answer: c & d
Explanation:
C and D provide a comparison of structures that encode genetic information for the cells. So, the correct option is C.
What are Prokaryotic and Eukaryotic cells?Prokaryotic cells are single-celled microorganisms known to be the earliest on earth. Prokaryotes include Bacteria and Archaea. The photosynthetic prokaryotes include cyanobacteria that perform photosynthesis. A prokaryotic cell consists of a single membrane and therefore, all the reactions occur within the cytoplasm which can be free-living or parasites.
Eukaryotic cells are defined as having a nucleus enclosed within a nuclear membrane and form large and complex organelles. Protozoa, fungi, plants and animals all contain eukaryotic cells which are classified under the kingdom Eukaryota.
Thus, C and D provide a comparison of structures that encode genetic information for the cells. So, the correct option is C.

Given what we know about the process of DNA replication, we can confirm that the star shown in the diagram represents the replication fork.
During the replication of DNA in the cellular process of multiplication, a structure known as the replication fork is formed. This fork is a structure that forms by helicases, which tear the hydrogen bonds that hold together two DNA strands in the form of a double helix.
The resulting structure contains two prongs, which are branches of the original DNA strand which are no longer doble or in the form of a helix. This area where the strands are separating into prongs is the replication fork which is being marked in the diagram by the star.
