Glycolysis and the citric acid cycle both produce carbon dioxide, which is a crucial byproduct (Krebs cycle). This oxidized carbon is a metabolic waste product that must finally be eliminated through transit to the lungs and subsequent exhalation into the environment.
What is the purpose of Krebs cycle?
Pyruvate is converted into three different products by the Krebs cycle: carbon dioxide, a little quantity of ATP, and the reduced molecules NADH and FADH.
Each acetyl group adds two carbon atoms to the citric acid cycle. On each cycle turn, two carbon dioxide molecules are emitted.
However, these do not include the identical carbon atoms that the acetyl group contributed on that turn of the circuit.
Therefore, carbon dioxide is constantly given off during the Krebs cycle.

During diffusion, molecules move from areas of blank concentration to areas of blank concentration. Diffusion does not require blank to move molecules.
Answers
Answer:
high; low; energy.
Explanation:
Diffusion can be defined as the movement of gas molecules from a region of high concentration to a region of lower concentration until an equilibrium is attained or reached. This mixing of gas molecules in the liquid or gaseous state is due to their kinetic energy of random motion i.e without requiring bulk motion.
This ultimately implies that, diffusion is a phenomenon through which gas molecules in either a gaseous or liquid state spread out in response to a concentration gradient, which is simply the difference in concentration of the gases across a space.
During diffusion, molecules move from areas of high concentration to areas of low concentration. Also, diffusion does not require energy to move molecules.
In conclusion, increasing the surface area of a gas increases its collision rate and it's considered to be an evolutionary strategy that maximizes the diffusion of gas molecules because it catalyzes the rate of a gaseous reaction.
A common genetic mutation that lowers levels of the enzyme cathepsin C severely reduces a person’s ability to ward off periodontitis, or gum disease. The enzyme triggers immunological reactions that destroy diseased cells and eliminate infections
in the mouth. But researchers are developing ways to restore the enzyme to normal levels. Once that happens, we will be able to eliminate periodontitis.
Which one of the following is an assumption on which the argument depends?
(A) Restoring cathepsin C to normal levels is the only way to eliminate periodontitis.
(B) Genetic mutation is the only cause of lowered levels of cathepsin C.
(C) Researchers will soon succeed in finding means of restoring cathepsin C to normal levels.
(D) Persons who do not have the genetic mutation that lowers levels of cathepsin C do not get gum disease.
(E) A person whose cathepsin C level has been restored to normal will not suffer from periodontitis.
Answers
Answer:
(E) A person whose cathepsin C level has been restored to normal will not suffer from periodontitis.
Explanation:
Considering the fact that there may be some other causes of periodontitis aside from the lowered levels of the enzyme.
Therefore, should there be some other causes of periodontitis, hence, it can be concluded the process of restoring the enzyme to normal levels might not be sufficient for eliminating periodontitis.
Hence, the author's argument is solely based on this assumption, and option. Hence, option (E) is the correct answer.

The concept illustrated in the flowchart is Natural selection. The correct option is 4.
What is natural selection?Natural selection is the process by which species evolve over time as the prevalence of certain traits increases or decreases in a population.
Natural selection, the mechanism by which species evolve over time, is depicted in the flowchart.
Overproduction of offspring causes competition for limited resources, resulting in a struggle for survival.
Based on their inherited characteristics, some people are better equipped to survive and reproduce than others.
These people are said to be "fit," and they are more likely to pass on their positive traits to their children. These advantageous traits become more common in the population over time, causing changes in the species as a whole.
Thus, the correct option is 4.

Answers
Evolution is the modification of heritable traits. The change in the earth's surface is directly linked to evolution as the formation of the species, abiotic factors, and gases happened due to changes.
What is evolution?
Evolution is the adaptation and survival of the modified organism due to changes in favorable environmental conditions. It is an important factor governed by natural selection.
The evolution and the change in the earth's surface are interconnected as the changes in the earth's crust made the presence of the living beings possible. The conditions at early times were unfavorable that underwent many changes till the present scenario.
The atmosphere and crust were unfavorable for the living beings that got changed and improved with oxygen quality, water, and the crust for the organism to exist, survive and reproduce to continue their lineage.

However, their heroic feat is for nothing, because their offspring all produce sterile young. This scenario is an example of
Answers
Answer:
Post reproductive isolation → Hybrid sterility
Explanation:
The biological concept of species states that individuals of a species can not mate and reproduce with individuals of another species. But if they get to reproduce, the progeny will not be viable or fertile. There will not be any reproductive success.
There are different reproductive isolation mechanisms, which are barriers that inhibit or interrupt the genetic flow between different species.
Reproductive barriers are isolation mechanisms that prevent mating between two or more species. The prezygotic mechanism avoids fertilization between individuals of different species, while the postzygotic mechanism impedes the zygote to develop and reach the adult stage.
Postzygotic mechanisms or barriers include
Hybrid inviability, Hybrid sterility, Hybrid decreased viability or fertility, Cytoplasmic interactions.In the exposed example, it seems that the mountains separating the frogs´ populations made a place for the development of postzygotic barriers, specifically hybrid sterility. Frogs from one population get to mate and produce offspring with the frogs of the other population, but their progeny is sterile.

What type of unconformity did Hutton see at Siccar Point and how was this uniformity formed?
Answers
Answer:
Hutton's Unconformity
At Siccar Point, during the lower Silurian Llandovery epoch around 435 million years ago, thin beds of fine-grained mudstone were laid down gradually deep in the Iapetus Ocean, alternating with thicker layers of hard greywacke formed when torrents swept unsorted sandstone down the continental slope. Siccar Point is a rocky promontory in the county of Berwickshire on the east coast of Scotland. It is famous in the history of geology for Hutton's Unconformity found in 1788, which James Hutton regarded as conclusive proof of his uniformitarian theory of geological development.

The teacher was unaware of the difference between suspension feeding and predation. The teacher thought that providing live copepods (2 mm long) and feeder fish (2 cm long) would satisfy the dietary needs of all of the organisms. Consequently, which two organisms would have been among the first to starve to death (assuming they lack photosynthetic endosymbionts)
Answers
Answer:
The correct answer is - Biwalves and sponges.
Explanation:
Suspension feeders are the organisms that depend on, for the dietary needs or nutriton, materials suspended in the water. The materials that are suspended are living organisms such as phytoplankton and zooplankton.
Biwalves and sponges are suspended or filter feeders and not predators like other organisms so providing copepods will not complete their food requirement and they will starve to death.
