The main difference between alcoholic fermentation and lactic acid fermentation is that of their end-products.
The primary distinction between lactic acid and alcoholic fermentation is that the latter results in the production of ethyl alcohol and carbon dioxide while the former yields lactic acid molecules from pyruvate.
Differences between the two processes include he following:
Pyruvate and lactate are produced directly after fermentation of lactic acid. Pyruvate is converted to ethanol by the two-step process of alcohol fermentation.End-products: Lactase and energy in lactic acid fermentation, while C02, alcohol, and energy in alcoholic fermentation are the end products. The enzymes involved in the fermentation processes of lactic acid are lactate dehydrogenase and pyruvate decarboxylase. Pyruvate decarboxylase and alcohol dehydrogenase are the two enzymes required for alcoholic fermentation.Similarities between the two processes include the following:
The two pathways convert ATPs from the breakdown of glucose.The two processes' major objective is to recycle NAD+ in order to keep glycolysis going and allow for the NAD+ to be reduced back to NADH in the process.Both processes release heat energy and are exergonic.Each produces 4 ATPs during glycolysis, the same amount as the other.To know more about fermentation, refer to the following link:

Why do leaves change colour explain?
Carotenoids are pigments that give leaves their yellow and orange colors. These pigments are always present in leaves, but become more visible as the chlorophyll breaks down in the fall.
Leaves change B due to changes in the pigments that are present in the leaf. Chlorophyll is the pigment primarily responsible for the green color of leaves and is present in all leaves. Chlorophyll is important for the process of photosynthesis, which allows plants to convert light energy into chemical energy. However, as the days get shorter and temperatures cool in the fall, the level of chlorophyll in a leaf decreases and the chlorophyll breaks down. This process causes the green color of leaves to fade, revealing other pigments that have been present in the leaf all along.

In a bird egg the developing embryo is inside the amnion, which contains fluid. The embryo gets nourishment from the yolk. The chorion lines the inside of the shell and helps protect the embryo. What structures in a human provide the same functions as these structures in the bird egg?
Answer: Placenta
Explanation:
Placenta is the outer protective envelope around the developing embryo. It is attached with the lining of the uterus. It has a permeable membrane which allows the entry of oxygen and nutrients to be supplied to the embryo. It helps in getting rid of harmful substances like carbon dioxide and waste from the developing fetus body.
For each of the following, circle the word that does not belong belong with the rest and then in ONE complete sentence, explain why it does not fit.
1. Coal, Oil, Solar, Power, Natural Gas
2. Biodegradable, Recycling, Sustainability, Deforestation
Answer: the words that doesn't belong include:
1.) Power
2.) Deforestation
Explanation:
1.) Coal, Oil, Solar and Natural Gas are considered to be sources of energy while POWER is not considered among the rest this is because it's energy in action and not a source of energy.
Coal, oil and natural gas are known as fossil fuels which are the most common sources of energy in industries and homes. These fossil fuels are destroyed by use, that is, they cannot be recovered. Alternative sources of energy is the solar which is gotten from the sun energy. Although not considered a very efficient energy producer, there are already discovered schemes that would provide us with an inexhaustible supply of energy which would also not cause any pollution problems.
2.) Biodegradable, Recycling and Sustainability are means by which pollution is being avoided in the environment. While DEFORESTATION is a process that can cause pollution of an environment, therefore it doesn't fit into the rest of other words.
Biodegradable materials can be broken down by microorganism. Examples include human and animal excreta. Recycling is the reprocessing of waste materials in order to be re-used. This reduces the amount of waste that are sent to incinerators. While sustainability is the maintenance of the ecosystem to remain diverse and productive over time. This could be seen in the preferred use of renewable energy over non renewable energy. But deforestation is the massive cutting down of trees which can cause soil erosion and climate changes leading to the pollution of the environment.

The structure of water molecule result in the hydrogen bonding in that:
The structure of a water molecule results in hydrogen bonding due to the distribution of electrons in the molecule. Water molecules are made up of two hydrogen atoms bonded to a single oxygen atom, forming the chemical formula H2O.What is the hydrogen bonding about?The oxygen atom has a higher electronegativity than the hydrogen atoms, which means it is more effective at attracting and holding onto electrons. As a result, the oxygen atom has a partial negative charge and the hydrogen atoms have partial positive charges.
Therefore, a partial positive charges on the hydrogen atoms are attracted to the partial negative charge on the oxygen atom of another water molecule, forming a hydrogen bond. This is a weak chemical bond, but it is significant enough to give water many of its unique properties, such as its high surface tension and ability to act as a solvent.

which statement could be categorized in the overlapping section of the Venn diagram?
A. uses pyruvic acid
B. has commercial uses
C. regenerates NADH
D. produces 36 ATP
The Venn diagram compares aerobic and anaerobic respiration. Uses of pyruvic acid could be categorized in the overlapping section of the Venn diagram.
In order to produce energy in the form of ATP molecules, aerobic respiration involves the complete breakdown of a glucose molecule in the presence of oxygen (36 molecules of ATP).
Contrarily, anaerobic respiration entails the partial breakdown of a glucose molecule to produce energy in the form of ATP molecules without the presence of oxygen (2 molecules of ATP).
The use of pyruvate is a characteristic shared by both aerobic and anaerobic respiration (pyruvic acid). The glycolytic process, which is the same for both processes, produces pyruvic acid.
While during anaerobic respiration, pyruvic acid is utilised to manufacture alcohol or lactic acid to renew NAD+, during aerobic respiration, pyruvic acid is used to build acetyl coenzyme A that enters the Krebs cycle.

How did Darwin prove his theory of evolution?
The patterns he had observed during his travels may be explained by Darwin's theory of evolution by natural selection.
In the case of the Galápagos finch species, it made sense that they would resemble one another as well as mainland finches, who most likely had a common ancestor. The best proof that organisms evolved from a common ancestor is similar DNA sequences. The existence of fossils proves evolution. These samples demonstrated how closely related ancient species were to those that existed during Darwin's time. A progression of evolution can be seen in fossils, which also offer compelling proof that species from the past were distinct from those present now.

Many lethal genetic disorders such as CF, Huntington’s, sickle cell anemia, Tay Sach’s, etc., persist in the human genome. How have these genes survived so many millennia of evolution (why didn’t they die out)?
They've been under the purview of balancing selection. This type of selection occurs when two alleles – one being the harmful variant and the other being the beneficial variant – both confer some sort of benefit in the presence of each other. This can work in two ways. Sometimes the balance of deadly and beneficial alleles can create a balance in the population, allowing for genes to persist over time. In other cases, the lethal genes can be beneficial if there is an environmental change and the deadly gene can offer protection from the new environment. Both of these scenarios create a balance of selection, allowing for the persistence of the gene over time. In some cases, the lethal genes are essential for the maintenance of certain gene complexes and, if lost, could result in decreased fitness. This type of selection is known as evolutionary pressure and it can also contribute to the longevity of certain genes. A third possibility is that some of the genes simply survive due to random genetic drift.
