When glucose is unavailable, the liver begins to break down fatty acids to supply the rest of the body with metabolic fuel. Explain why fatty acid-derived acetyl-CoA is not catabolized by the citric acid cycle but is instead diverted to ketogenesis when no glucose is available.

Answers

Answer 1

Answer:

Fatty acid degradation produces acetyl-CoA

When carbohydrate concentrations drop, any available oxaloacetate is diverted to gluconeogenesis to produce the glucose necessary for red blood cell and brain function. If acetyl-CoA cannot enter the citric acid cycle (and acetyl-CoA cannot be converted to pyruvate in mammals), it is converted to ketone bodies.

Mrs. Tuff is now insistent that Tommy sits in her lap and as she speaks to Tommy he begins to cry more and refuses to open his mouth. Mrs. Tuff continues to tell Tommy that it won't hurt and if he only opens his mouth, he will get a toy. What steps can you take now to get Tommy to cooperate?

Answers

Solution :

Tommy is a young boy and is feeling afraid to open his mouth and show it to Mrs. Tuff. Something had stuck into his mouth and he is finding it difficult to eat anything and it is paining a lot.

Mrs. Tuff is insisting tommy to sit on her lap so that she could examine him but he refuses to open his mouth and cries loudly. I told Tommy that it is for his own good and he should listen to Mrs. Tuff and open his mouth so that Mrs. Tuff could treat him. By this Tommy will get relief from his pain and he will better.

I also insisted Tommy to open his mouth as it will cause him any pain. I gave something to Tommy so he can get distracted and open his mouth. Mrs. Tuff also told him that he will get a toy if he opens his mouth.

This is how I got Tommy to cooperate with Mrs. tuff.

A tech is using the H (flagellar) antigen to serotype a suspected Salmonella species. The results of the serotyping are agglutination with one well that indicates a group of possible serotypes, not one particular serotype. Quality control passed. Why did this occur

Answers

Some Salmonella H antigens can occur in multiple strains and serotypes

An antigen (Ag) is any molecule/structure such as, for example, a molecule present on the surface of a pathogenic microorganism, that can be bound by a specific antibody and/or B-cell receptor.  The Kauffmann–White classification scheme is a system that was adopted for use in 1934 in order to categorize different serotypes of the bacterial genus Salmonella, based on their somatic-surface antigens. The system is a practical (diagnostic) method based on the variation in the somatic (O) and flagellar (H) antigens present in the cell wall of Salmonella species. In this classification system, 'O' antigens are determined based on oligosaccharides which are associated with lipopolysaccharide, while the "H" antigens are distinguished by the protein content of the Salmonella flagella.

Some of the typical properties of cancer cells are: (1) Self-sufficient growth and proliferation, (2) Defects in intracellular control mechanisms that normally arrest or permanently stop cell division in response to stress or DNA damage, (3) Ability to escape from home tissues (invasiveness) and to survive and proliferate in foreign sites (metastatic ability), and (4) Instability of the genome. True or False

Answers

Answer:

True

Explanation:

Cancer cells are abnormal cells that divide aggressively to form solid tumors, thereby differing from normal cells. Cancer cells do not need any stimulation to multiply them, i.e., they can synthesize their own growth factors that trigger uncontrolled cell proliferation. Mutations in genes associated with the progression through the cell cycle and programmed cell death (i.e., apoptosis) are a well-known hallmark of cancer cells. The mutated genes can be either 1-tumor suppressor genes that slow down cell division and repair DNA mistakes or 2-proto-oncogenes that normally help cells grow, and whose mutations cause normal cells to become cancerous (oncogenes are mutated forms of proto-oncogenes). Cancer cells are characterized by their invasiveness and metastatic potential, i.e., their ability to spread to healthy surrounding tissues through the lymph system and/or bloodstream, where these cells proliferate and produce new tumors. Finally, genomic instability, i.e., the increased susceptibility of cells to acquire and spread mutations at the genome level, is also a hallmark of cancer cells. Genomic instability results from damage to genes that regulate cell division and tumor suppressor genes.

<< Read Less

Answers

Answer:

Here's a better answer.

There are multiple lines of evidence that provide support for common ancestry and evolution; this would be homologous features of anatomy and embryology and fossil records.

In comparative anatomy, there are many similarities between species because all life is related. Homology is similarities seen because of the ancestry of features or genes in an organism. Similarities can show descent from common ancestors and similarities can be seen in body structures, development, and DNA. Homologous structures are similar traits found in two different species that are the result of having a common ancestor. These structures are similar but may have different functions. An example of this might be the homologous structures in the limbs of humans, cats, whales, and birds. And then there are analogous structures, which similarly is that the structure of different species are similar because the trait is advantageous, not because they are related. An example of this is sharks and dolphins having similar fins. Along with anatomy is Embryology. Different species can have similar embryos because they come from a common ancestor. They may start with the same developmental plan but change drastically as they grow up. An example of this is seen in the early stages of development between fish and chicken embryos.

Next up, the fossil record provides evidence that supports common ancestry and evolution.  The fossil record provides us with visual evidence for evolution. The fossil record directly allows us to pinpoint if there are any similar structures amongst organisms and see if there are any vestigial structures from ancestors that remain in organisms that still roam today. The fossil record depicts evolutionary change over the past four billion years, which can be seen through transitional forms, increasing complexity of life, and geographical distribution. Transitional forms are fossils that show intermediate states between an ancestral species and its evolutionary descendants. Increasing complexity is seen as life on earth becomes more complex. That and geographic distribution which has been studied closely and found that the continents have moved over time and that the fossil record reflects this movement. Fossils of different animals can be found on different continents around the world due to continental drift.

Explanation:

The various pieces of evidence that support common ancestry are homologous organs, fossil records and embryological studies.

What is common ancestry?

The phrase "common descent" in evolutionary biology refers to a particular group of species' shared ancestry. The creation of new species from an original population is a component of common descent. Two creatures are considered to be closely related if they have a recent common ancestor.

In contrast, molecular genetic techniques can also be used to establish shared ancestry from a single universal ancestor of all living things. Natural selection and other factors, such geographic isolation, are considered to have contributed to many speciation episodes during this development from a universal common ancestor.

According to the common ancestry idea, every living thing descended from a single progenitor. Hence, the Theory of Common Descent contributes to our understanding of why traits in species living in different geographic regions vary, why some traits are highly conserved across broad animal classifications (such as vertebrates or tetrapods), why seemingly unrelated species (such as birds and reptiles) share hereditary physical and genetic traits, and why successfully adapted organisms typically have more offspring.

Therefore, embryological studies, fossil studies and homologous organs can help in the study of common ancestry.

The kelp population would remain unchanged; sea otters do not eat the kelp.

The kelp population would remain unchanged: sea otters eat urchins, but not exclusively.

Answers

Answer:

The kelp population would decrease: sea otters eat urchins, and urchins eat kelp.

Explanation:

The diagrammatic illustration in this question is showing a food web made up of a variety of species feeding on one another. As shown in the food web, sea otters are one of the top predators that can eat a wide variety of organisms.

Sea urchins feed directly on kelp, however, the population of sea urchins can be controlled by sea otters which feed on sea urchins. Hence, if population of sea otters declined, more sea urchins will be available to feed on the kelp population, hence, will DECREASE.

Answer:The kelp population would decrease: sea otters eat urchins, and urchins eat kelp.

Because the otter population decreases the urchin population increases and therefore the demand for kelp increases and the kelp population will decrease as the population of urchins increases and it feeds on the kelp and due to the reduction in otters there is nothing controlling the urchin population

First, there is a need to understand what the carrying capacity is as it relates to the environment:

Carrying capacity refers to the maximum number of individuals of a particular species that and environment can support based on the resources it has. The population of a species in an environment grows and oscillates around the carrying capacity of the environment.

Now let us look at the graph. The population size grew from 0 and then leveled off at 2,000 with time. The leveling-off also happened without any oscillation, meaning that the maximum population size the environment can support is 2,000.

Hence, the portion on the graph that indicates the carrying capacity would be the plot where the population size is 2,000 and the time being between 12 and 18. This has been circled and labeled as 'K' in the attached image.

Which of the following statements about active transport is true?

Molecules move down the concentration gradient.

ATP is not required to move molecules through the membrane.

ATP is formed as molecules pass through protein channels.

It results in a higher concentration of molecules on one side of the membrane.

Answers

Answer:

It results in a higher concentration of molecules on one side of the membrane.

Explanation:

Active transport is the transport of molecules up the concentration gradient. This means that molecules are going from low density to high density. This is the opposite of natural diffusion. So, it requires ATP to move the molecules this way. Diffusion normally occurs to maintain homeostasis and an equal amount of concentration on both sides of a membrane. But, with active transport, since molecules are moving up the gradient, the opposite happens and the concentrations are unequal.
