In glycolysis, pyruvate, ATP, and NADH are produced. The lactic acid fermentation process uses the NADH molecule from glycolysis to convert pyruvate into lactate. During lactic acid fermentation, the NADH molecule transfers electrons to the pyruvate molecule and is converted to NAD+. How do you think this transfer of electrons helps the lactic acid fermentation process repeat itself? will give brainliest

Answers

Answer:

Explanation:

Fermentation does not involve an electron transport system, and no ATP is made by the fermentation process directly. Fermenters make very little ATP—only two ATP molecules per glucose molecule during glycolysis. ... During lactic acid fermentation, pyruvate accepts electrons from NADH and is reduced to lactic acid.

The NADH needed to convert pyruvate to lactate is supplied by this reaction of glycolysis, so the transfer of electrons helps to repeat the lactic acid fermentation process as lactate is reduced to pyruvate to regenerate NAD+ which is are reused for uninterrupted operation.

What is Glycolysis?

Glycolysis is defined as the metabolic pathway that converts glucose to pyruvate where the free energy released in this process is used to form the high-energy molecule adenosine triphosphate and the lesser nicotinamide adenine dinucleotide. It is a sequence of ten reactions catalyzed by enzymes.

During glycolysis , ATP and NADH are produced where lactic acid fermentation process uses NADH molecule from glycolysis molecule to convert pyruvate to lactate. During lactic acid fermentation, NADH transfers its electron to pyruvate and is oxidized to NAD+ while pyruvate is reduced to lactate.

NAD+ assisted dehydrogenation and phosphorylation of glyceraldehyde-3-phosphate (G3P) to 1,3-biphosphoglycerate (1,3-BPG) is coupled to lactate production where NADH is supplied to convert pyruvate to lactate, hence, the transfer of electrons helps the lactic acid fermentation process to repeat itself as the reduction of pyruvate to lactate regenerates NAD+ which is reused for uninterrupted operation

Thus, the NADH needed to convert pyruvate to lactate is supplied by this reaction of glycolysis, so the transfer of electrons helps to repeat the lactic acid fermentation process as lactate is reduced to pyruvate to regenerate NAD+ which is are reused for uninterrupted operation.

Answers

Individual a has the higher fitness because more of its offspring survived compared to the original amount of offspring

In natural selection when more offspring is survived is a sign of higher fitness of the particular population, hence given statement is true.

What is natural selection?

Most qualities are inherited, there are more children generated than can survive, and offspring with more advantageous features will survive and have more offspring than those with less advantageous traits leading to the inevitable process of natural selection.

Since there are only so many resources available, more creatures are born than can live those who are better at obtaining food.

Mating or evading predators will have a higher chance of thriving, procreating, and passing on their DNA.

Therefore an individual in the population has offspring to survive more in number.

Answers

Answer:

4, based on the assumption that the R allele is dominant over the r allele, and that the T allele is dominant over the t allele.

Explanation:

Any bush with a dominant petal color allele (R) will have red petals. This includes Rr and RR.

Any bush with a dominant bush size allele (T) will have a tall bush. This includes Tt and TT.

The only way to acquire a short bush or pink petals is to have two recessive alleles together (tt, rr).

RRTT, RrTT, RRTt, and RrTt -> red petals with tall bushes

RRtt, Rrtt -> Red petals with short bushes

rrTt, rrTT -> pink petals and tall bushes

rrtt-> pink petals with short bushes.

Because he was well aware of the effect his theory of evolution would have on the public and on the Church of England, Darwin delayed publishing his work for several decades while he gathered additional evidence. After invoking selective breeding of domesticated species as evidence that groups of organisms are capable of change, he then proposed that natural populations can change as well. On which two lines of evidence did he base this proposal? a) Individuals within a population vary, yet island species around the world all appear to be related to each other.b) Organisms produce more offspring than can be supported by their environment, and adaptations to specific environments increase an organism's ability to survive and reproduce.c) Organisms within a population vary, and all populations produce more offspring than can be supported by the environment, resulting in competition for survival within the population.d) Some individuals leave more descendants than other individuals, but the individuals in a population are essentially identical to each other.e) Some individuals within a population have greater success in survival and reproduction than others, and favorable traits within a population will accumulate over generations.

Answers

Answer:

c) Organisms within a population vary, and all populations produce more offspring than can be supported by the environment, resulting in competition for survival within the population.

Explanation:

Darwin's theory was based on the evidence of natural selection and survival of the fittest.

Evidence of Darwin's theory were observed from the variation in the population which is supported by the environmental factor (natural selection) and these population than produce offspring, resulting in competition for survival within the population (survival for fittest).

why is the linner wall of alimantary canal not digisteg although the digestive enzymes can digest all the materials that make cell?

Answers

Answer:

There are no options to this question but it can be answered by giving a general explanation. The answer is:

Because the digestive enzymes are not in direct contact with the cells that make up the walls of the alimentary canal. The walls are protected by mucuous lining.

Explanation:

Digestion of our ingested food is an important process for the effective functioning of our body system. Digestion is the process whereby food, which are usually macromolecules, are broken down into simpler molecules usable by the body. After food is taken in from the mouth (ingestion), it must be broken down by chemical and mechanical means.

The chemicals means is through digestive enzymes, which are proteinous chemical substances. The digestive system consists of the alimentary canal or digestive tract, which is a tube-like organ that forms the path for food passage. Since digestive enzymes secreted during digestion can disintegrate every macro biomolecule e.g protein, carbohydrate etc, it can also break down the molecules that make up the cells of the tract wall.

However, the digestive enzymes does not break down the cells of the canal's wall because the body system secretes mucus, which lubricates the passage of food along the canal. It also prevents the digestive enzymes from coming in contact and acting on the macromolecules that make up the cells of the walls of the alimentary canal.

C. selective pressure

D. stabilizing pressure

The answer is B) Adaptation

Explanation:

Adaptation is the process whereby an organism becomes well suited to survive in its natural environment, which is aided by the possession of certain traits called adaptive features. For example, the fins of a fish makes it fit to survive in an aquatic environment, likewise the opposable thumbs of humans make us well suited to survive in our environment.

As stated in the question, the opposable thumb i.e. movement of the thumb independently of the other four fingers, is a characteristics of primates. This unique feature (opposable thumb) allows us to grab things, get a good grasp of tools, use tools effectively, write things, etc. All these ability due to the possession of opposable thumb increases our chances of survival. Hence, the possession of opposable thumb is regarded as an ADAPTATION

About thirteen different species of finches inhabit the Galápagos Islands today, all descendants of a common ancestor from the South American mainland that arrived a few million years ago. Genetically, there are four distinct lineages, but the thirteen species are currently classified among three genera. The first lineage to diverge from the ancestral lineage was the warbler finch (genus Certhidea). Next to diverge was the vegetarian finch (genus Camarhynchus), followed by five tree finch species (also in genus Camarhynchus) and six ground finch species (genus Geospiza). If the six ground finch species have evolved most recently, then which of these is the most logical prediction?

Answers

Answer: Firstly it should be noted that, the chances of hybridization between two ground finch species should be less than the chances of hybridization between two tree finch species. On this wise, their genomes would be more similar to each other than are the genomes of the five tree finch species. Secondly, they should be limited to the six islands that most recently emerged from the sea.

Thirdly, they should share fewer anatomical homologies with each other than they have shared with the tree finches.

Fourtly, their genomes should be more similar to each other than are the genomes of the five tree finch species.

A skin cell of a red fox has 34 chromosomes. You look at the cell under a microscope and see that it has 34 chromosomes and one nucleus. Several hours later, you look at the same cell a second time and see that it has double the amount of DNA and one nucleus. A little while later, you see the cell for a third time and notice that it has 68 chromosomes and two nuclei. What stage of the cell cycle was this cell in when you viewed it at each time point

Answers

Answer:

See the answer below

Explanation:

At the first look, the cell was in G1 phase of the cell cycle. At the second look, the cell was in the G2 phase of the cell cycle, and at the third look, the cell was in Telophase.

At the G1 phase of the cell cycle, the cell mainly experiences growth and development. Nothing much happens except that the cell increases in volume.

At the G2 phase of the cell cycle, synthesis of DNA has taken place during the S phase and the amount of DNA present in a cell is doubled at this stage.

At the telophase stage of the cell division in the cell cycle, chromosomes have completed their migration to the poles and each pole appears like a nucleus with their individual chromosomes under the microscope. The cytoplasm is yet to divide at this stage, hence, everything still appears as a single cell.
