Answers

Jejunum is the central portion of the small intestine transports food rapidly to the ileum via wave-like muscle contractions. Ileum is basically the longest section of your small intestine.

What is alimentary canal?

The gastrointestinal tract is the digestive tract or passageway that connects the mouth to the rectum.

The small intestine's entire wall is made up of folds. The duodenum is a C-shaped structure located at the start of the small intestine. The jejunum comes after the duodenum.

The main distinction between the duodenum and the jejunum is that the duodenum contains submucosal Brunner's glands, whereas the jejunum does not.

Thus, this can be the comparison between jejunum and ileum.

how many pgal molecules will it take to make one molecule of glucose

Answers

PGAL molecules will it take to make one molecule of glucose Calvin Cycle (light independent reactions).

Phosphogly ceraldehyde, or PGAL for short, is a 3-carbon compound as you can see from the diagram of its chemical shape. as soon as PGAL has been made, its carbon atoms are used to synthesize different natural compounds, which are crucial for the increase and survival of plants.

The response is catalyzed via the enzyme ribulose bisphosphate carboxylase/oxygenase (Rubisco). The six-carbon intermediate reacts with water and decomposes into two identical 3-carbon molecules called phosphoglycerate. those, in turn, react with ATP and NADPH to produce PGAL molecules.

One turn of the Calvin Cycle fixes 3 CO2 C O 2 molecules and generates 1 molecule of phosphoglyceraldehyde (PGAL). So, whilst 54 molecules of CO2 C O 2 enter the Calvin Cycle, 18 molecules of phosphoglyceraldehyde (PGAL) also called glyceraldehyde-3-phosphate (G3P) will leave the cycle.

What is the definition of epistasis?​

Answers

Genetics entails a phenomenon, epistasis wherein the impact of a gene mutation depends on the absence or presence of mutations in one or more other genes referred to as modifier genes.

As a result, epistatic mutations behave differently when they occur alone than when they do together. Particularly, epistasis is used to show that other genes can obscure the effects of gene variants.

It has been determined that understanding gene interactions, also known as epistasis, is crucial to understanding the function of genetic pathways, their structure, and the evolutionary dynamics of complex genetic systems. With the advent of high output functional genomics and the development of system techniques in the area of biology, there is a renewed acceptance for both the importance of investigating gene interactions and to address concerns in a coordinated quantitative fashion. The recently found cognition, which links the genetic underpinnings of evolution to specific molecular modifications, joins this.

Cells transport molecules into the cell in many different ways. One method is through endocytosis, shown in the model. In endocytosis, the cell brings specific molecules it needs, including fluid, into the cell. Why does the structure of the plasma membrane make this type of transport necessary for fluids?

Answers

The structure of the plasma membrane make this type of transport necessary for fluids because while the heads of the phospholipid structure attract water, the tails are hydrophobic. The model depicts how the hydrophilic section folds around the fluid molecules to bring them into the cell so they do not need to pass through the hydrophobic tails.

Answers

Answer:  axial= 3 skulls. and the rest go to appendicular

Explanation:   The maximum number of individuals that could be represented by the bones is 22. This is because each bone could be from a different person. At first glance some may assume that there would be only 3 people because there were only 3 skulls, however, there were 4 right femurs, so that means there is a missing skull to go with one of the right femurs. With this in mind, you can only assume that each bone goes to a separate individual until more evidence appears.

The dose response curve indicates that higher concentrations of the drug are more effective at decreasing cell viability of the cancer cells.​

Answers

High attrition rates in the development of cancer drugs have been attributed, in part, to the low repeatability of preclinical drug discovery models. Ineffective experimental planning and a lack of scientific transparency may result in experimental biases that have an impact on the reliability, validity, and reproducibility of results.

Here, we identify causes of experimental variability in traditional 2D cell-based cancer drug screening to assess the impact of confounders on cell viability for platinum medicines (cisplatin and carboplatin) and a proteasome inhibitor treated MCF7 and HCC38 breast cancer cell lines (bortezomib). According to variance component analysis, differences in cell viability were more frequently related to the selection of the medication and cell line than to the kind of growth media or the length of the test incubation period.

Due to the possible danger of evaporation and the resulting impact on dose-response curves, alternative ways of keeping diluted pharmaceutical medicines and the use of DMSO controls should be carefully considered. For HCC38, MCF7, MCF-10A, and MDA-MB-436 cells that had been treated with bortezomib and cisplatin, the results were repeatable thanks to the optimization of the experimental conditions, which also significantly enhanced the quality of the data. Together, these results show that by identifying potential confounders and subsequently optimizing experimental parameters for each cell line, cell-based drug screens' replicability (the analyst repeats the experiment multiple times) and reproducibility (different analysts perform the same experiment under different experimental conditions) can be enhanced.

Answers

Mendel's model of genetics is not the only model of inheritance, because may be another model, was also presented by another scientist.

How is Mendelian inheritance different from Non-Mendelian inheritance?

The Mendelian quality is determined by dominant and receding alleles of one gene. On the opposite, non-Mendelian traits are not determined by dominant and relapsing alleles and can be governed by more than one gene. Non-Mendelian inheritance is any design in which traits do not segregate in accordance with Mendel's laws.

The genetic traits that follow the truth of Mendel's law are known as Mendelian inheritance while the genetic traits. Non-Mendelian genetics are inheritance motif that is different from Mendelian inheritance.

The lactose (lac) operon in E. coli is an example of a gene that is repressed when lactose is not available in a cell. In 3-5
sentences, explain what this means, using correct terminology (4 points)

Answers

The set of genes known as the lactose operon in E. coli controls the synthesis of the enzymes required for breaking down lactose in bacterial cells.

The genes in the lac operon are active when lactose is not present.

When lactose isn't present, the lac repressor forms a strong bond with the operator and stops RNA polymerase from starting transcription. However, the lac repressor loses its capacity to bind DNA when lactose is present. It detaches from the operator and makes room for RNA polymerase to start transcription of the operon.

It is an illustration of an inducible operon where the transcription of structural genes is induced by the presence of a crucial metabolic component (lactose, an alternative energy source).

The lactose molecule acts as a signal molecule if lactose is present in the medium because it binds to the repressor and prevents it from binding to the operator.
