Glycolysis uses 2 ATP and produce 4ATP. So the net gain is true.
Oxygen is used in the Electron Transport Chain as the final electron recipient from complex 4 cytochrome a₃.
Explanation:
Glycolysis is the process which is common in all forms of respiration where glucose is metabolized into pyruvate. This process is very essential to continue the next steps of different respiration. Glycolysis requires 2 molecules to process substrate level phosphorylation to convert glucose to glucose 6 phosphate and fructose 6 phosphate to fructose 1, 6 bisphosphate. But it produces 4 ATPs. Thus net gain is 2ATP.
In ETC, the hydrogen carriers NADH and FADH gives off the hydrogen to reduce the complex 1 and 2 respectively and itself gets oxidized. Thus the electron given off is transferred between 4 complexes to finally give off to oxygen to form water.
Answer:
By changing allelic association recombination can aid solution, either helping to bring two beneficial alleles from an otherwise well adopted genome. He natural selection only acts on the population heritable traits selecting for the beneficial alleles and thus increasing their frequency in the population, while selecting against deleterious alleles and thereby decreasing their frequency as the process known as adaptive evolution
Answer:
The reason why the abundance of the mammals be successful is that it provides food and oxygen for the survival of the mammals.
These plants also attract the mammals which helps in mating of the animals and producing more offspring.
A healthy animal will only lead to the producing more healthy offspring and by getting proper food the animals will produce successful offspring.
Answer:
<u>Abiotic</u>: Clouds, rocks, wind, temperature, ocean currents, sunlight, topograhy, precipitation, air quality, soil, water, humidity, climate.
<u>Biotic</u>: Grass, wolves, fish, microbes, insects, trees, birds, moss, animals, bacteria, organic matter, plants.
Explanation:
Biotic factors are things that are or were once living. Abiotic factors are things that are not and never were living.
Answer:
The correct answer is e. <em>Postzygotic barrier.</em>
Explanation:
Different species can not mate and produce viable, healthy and fertile descendence, due to certain mechanisms of <u>reproductive isolation</u>.
These mechanisms involve different kinds of barriers that make it difficult for two different species to produce viable and fertile progeny.
One of these is the <u>postzygotic barrier</u>, which avoids the hybrid zygote to develope to adultness. In these situations, there is a mix of chromosomes that can not happen to meet or that they lack information.
There are cases in which the embryo dies, but some times the individual can reach some more advanced develope stages. If this is the case, in general, they can not survive because the organism is unhealthy. And if they reach adultness in good sate they can not leave descendence, as they are sterile.
