If CO2 is increasing but ethanol is not increasing, what is occurring?
Answers
Answer:
Both the products of yeast fermentation, ethanol and CO2, act as product inhibition. Its not toxic, but CO2 will inhibit further fermentation activity of culture yeast.. Hello there. ... Its not toxic, but acid produced during fermentation, will increase the H+ ions in ur media which will hinder further yeast growth.
When no increase in ethanol concentration, while the increase in carbon dioxide, there will be a decrease in the fermentation rate.
What is the role of carbon dioxide in ethanol fermentation?Ethanol fermentation is the process of conversion of sugars into carbon dioxide and alcohol.
The ethanol and carbon dioxide are the products of the ethanol fermentation reaction. The products act as inhibitors of the reaction.
With the increase in the concentration of carbon dioxide, the inhibitor concentration increases, resulting in the inhibition of the fermentation reaction.

Answers
Answer:
D
Explanation:
D diagram represent as pedigree chart would be the most beneficial in determining the inheritance of a trait or disease though several generations. So, the correct option is D.
What is Pedigree chart?A pedigree chart, which is most frequently used to represent people, show dogs, and race horses, depicts the incidence and manifestation of phenotypes of a specific gene or organism as well as its descendants through one generation to the next.
A pedigree chart that includes all the family members can serve as a substitute for a family tree. They can have a hereditary condition or be a disease carrier. Standard symbols are employed inside the pedigree analysis to distinguish between various lineages. The most useful tool for determining how a characteristic or disease is passed down across numerous generations is a pedigree chart.
Therefore, the correct option is D.

9. In order to grow two of the exact same plants, a person would reproduce them asexually because the
a) genetic diversity is greater. b).offspring would be genetically identical. c. recessive traits would emerge d). negative traits are suppressed.
Answers
Answer:
b).offspring would be genetically identical.
Explanation:
To grow the exact same plants, a person would reproduce asexually because the offspring would be genetically identical. Hence, the correct answer is option b.
What are the different modes of reproduction?There are two different types of reproduction: sexual reproduction and asexual reproduction. In sexual reproduction, the offspring that are formed are slightly different from the parents. This is due to meiotic cell division. Variations in offspring are seen as a result of gene crossing over.
In asexual reproduction, all the offspring are identical to the parents. It is similar to mitosis. Recombination and crossing over do not occur here.So in order to get the exact same plant, this type of reproduction is done by taking a branch from a tree, etc. Others are incorrect statement options.
Hence, to get the exact same plants, a person should go for asexual reproduction, as they produce genetically identical offspring. Option b is the correct answer.

Answers
If the seat belts on any passengers are fastened, the vehicle will also slow down until everyone is at rest. Additionally, if a car was moving straight when another car struck it, the direction of the car would shift.
What are newton's three law of motions ?According to the first law, until a force acts on an item, it will not alter its motion. According to the second law, an object's force is determined by multiplying its mass by its acceleration. According to the third law, when two objects interact, they exert equal-sized and opposite-direction pressures upon one another.
There's a fourth law , it states that every object tends to remain in the state it is in right now. We refer to this propensity as inertia. Every object tends to remain in the state it is in right now.
Therefore, If the seat belts on any passengers are fastened, the vehicle will also slow down until everyone is at rest (First law) . Additionally, if a car was moving straight when another car struck it, the direction of the car would shift (Third law).

Answer:
The pelvis is the best sex-related skeletal indicator, because of distinct features adapted for childbearing. The skull also has features that can indicate sex, though slightly less reliably. Males have a square jawline and the line between the outer edge of the jaw and the ear is vertical. Conversely, in females the jaw is much more pointed and the edge of the jaw slopes gently towards the ear.
Explanation:
Two frog populations (same species) living in two neighboring lakes sing slightly different courtship songs. Increased irrigation makes the land between the two lakes wetter, allowing frogs to expand their ranges to the area between the lakes. Females in both populations prefer loud frogs to quieter frogs but do not distinguish between the two slightly different songs. Assuming that courtship song differences have a genetic basis, predict what will likely happen to the songs of the two frog populations.
A. You cannot predict a change in the courtship songs at the two lakes.
B. Disruptive selection will cause the songs to differentiate even more.
C. The songs will become more similar to each other.
D. Males will become louder.
E. Genetic drift will cause the songs to differentiate even more.
Answers
Answer:
C. The songs will become more similar to each other.
Explanation:
To answer this question, first, you need to remember that both populations belong to the same species, so they can mate because there is no reproductive barrier. The only limiting physical factor impeding individuals of both groups to cross was the piece of land before the land got wetter. So once populations got together, individuals can easily mate.
One population´s males exhibit a courtship song that slightly differs from the one of the other group. This difference has a genetic basis. But females hardly notice the difference. All of them prefer loud frogs to quieter frogs, independently of the population to which they belong.
So when the two populations get together, individuals get mixed. Females do not recognize males of their group, and during the breeding season, all females will mate the most with louder males of any of the population. So females from population A might mate with males from population B, and females from population B might mate with males from population A. So after mating season, there is also a genetic mixture between populations.
The new generations will carry elements of both genotypes. So males´ songs will be even more similar to each other. Songs will become more similar to each other because individuals of both populations are mixed and mated, and their genes intercrossed, producing new individuals with genes of both populations.

What is population growth?As the population grows, there will be an increased demand for food, water, energy, and land, which will lead to habitat loss, deforestation, pollution, and climate change. These factors can exacerbate other ecological issues, such as the number of species in an extinction vortex and the spread of disease and parasites via corridors. Therefore, it is crucial to address the root cause of these problems by promoting sustainable practices and reducing our impact on the environment.

b. Ss (male) × ss (female)
c. 50% Ss, 50% ss
d. 3 long hair (ss), 3 short hair (Ss)

Proteins are important in plants in order to synthesize cellular components (e.g., organelles), provide structural support cytoskeleton) and carry to metabolic reactions (enzymes).
Proteins are fundamental biomolecules composed of amino acids linked by peptide bonds.In cells, proteins can play diverse structural and enzymatic roles.For example, structural proteins are required to synthesize ribosomes, which serve to assemble other proteins that form the cytoskeleton of cells. Moreover, enzymes are proteins capable of catalyzing chemical reactions such as photosynthetic reactions.In conclusion, proteins are important in plants in order to synthesize cellular components (e.g., organelles), provide structural support cytoskeleton) and carry to metabolic reactions (enzymes).

Carbonate is important to marine life, especially those with exoskeletons and shells, who form their protective casings from carbonate.
