Today, you have learned some basic general information about bacteria that cause infections and bacteria that protect
and benefit us, living inside and on the surface of our bodies. So, here is a question for you to apply the knowledge you
gained today:
Ms. AB was traveling and caught a nasty flu on the plane. But because she had work and school she could not take any
time off to rest during her flu. 2 weeks after she contracted the flu, she no longer had the fever and sore throat, but her
nose was still stuffy, and she was suffering from sinus headaches. She went to her doctor, who diagnosed her with a
sinus infection and prescribed her a course of antibiotics. Ms. ABC took the 7 days of antibiotic therapy, but she is now
back at her doctor's office with a yeast infection and diarrhea. Explain, why Ms. ABC developed the sinus infection. Then
explain why she developed a yeast infection and diarrhea after the course of antibiotics
Answer:
Antibiotics killed the bacteria that cause infection but they can also kill beneficial bacteria . thus Ms ABC developed a yeast infection and diarrhea after course of antibiotics because antibiotics distrub natural balance of beneficial bacteria in her intestine.
Ms. ABC developed a yeast infection and diarrhea after the course of antibiotics because the exposure to antibiotics may kill beneficial bacteria which prevent other diseases to occurs in the body.
What is an Antibiotic?Antibiotics may be defined as a type of medicine that significantly inhibit the growth of microorganisms especially bacteria inside the body of living organisms. Such type of antimicrobial substance may either kill or inhibit the growth of bacteria.
It is the most prevalent kind of antibacterial agent for conflicting bacterial infections, and antibiotic medications are tremendously utilized in the treatment and prevention of such infections.
With the effect of antibiotics, beneficial bacterial species that are living in the intestine may also be killed. Due to this, Ms. ABC becomes susceptible to other types of infections like yeast and diarrhea.
Therefore, exposure to antibiotics may significantly kill beneficial bacteria which prevent other diseases to occurs in the body.

4. A bacterium is discovered with new mutated form of isocitrate dehydrogenase that catalyzes the same reaction but produces hydrogen gas instead of NADH. a. Write a balanced equation for the new reaction. b. What affect does this mutation have on the amount of ATP produced from one glucose molecule
A bacterium is discovered with a new mutated form of isocitrate dehydrogenase that catalyzes the same reaction but makes H₂; the reactant is isocitrate, and the product is alpha-ketoglutarate. As the proton count decreases, less ATP is produced.
What is the importance of the proton gradient in energy production?The proton gradient is formed during the electron transfer chain (ETC) by using all the NADH and FADH₂ that are derived from the glycolysis and kreb cycle. NADH and FADH₂, for example, are two compounds that travel through the different complexes to create the proton gradient, which later produces ATP; however, when H₂ is produced instead of NADH, less of a proton gradient is formed, and thus less ATP is produced. The equation is isocitrate+ NAD+ → alpha-ketoglutarate +CO₂ + H+
Hence, the reaction is composed of substrates isocitrate, NAD+, and products alpha-ketoglutarate, CO₂, and a proton (H+), which will be formed with significantly less ATP than the normal ATP produced from the one glucose.

As the level of Carbon Dioxide in the atmosphere increases, how will (is) primary productivity impacted? How does this impact populations of primary consumers?
Answer:
Rising atmospheric carbon dioxide (CO2) and nitrogen (N) deposition increase directly the resource availability to plants, and can increase plant growth and net primary productivity (NPP; Norby et al., 2005).
Net primary productivity varies among ecosystems and depends on many factors. These include solar energy input, temperature and moisture levels, carbon dioxide levels, nutrient availability, and community interactions (e.g., grazing by herbivores) 2.
Explanation:
Primary producers capture light from the sun and carbon dioxide from the environment and finally transform it into energy.
What do you mean by Net primary productivity (NPP)?Net primary productivity may be defined as the amount of matter accumulated by plants per unit area in a given time.
Primary productivity depends on photosynthesis, where carbon dioxide gets converted to energy. If the level of Carbon Dioxide in the atmosphere increases, the photosynthesis rate increases, and finally the primary productivity increases.
Therefore, Primary producers capture light from the sun and carbon dioxide from the environment and finally transform it into energy.

the potential for antibiotic resistance was recognized in the early 1940s, almost immediately after the first large-scale clinical use of penicillin, the first antibiotic. mass production of penicillin was part of the war effort of world war ii, when the drug was used widely by military populations to treat the wounded. however, even before the war had ended, resistance to penicillin was already being reported. in 1940, british biochemists sir ernst boris chain and sir edward penley abraham published a report about a bacterial enzyme capable of destroying penicillin. in the following decades, overuse and repeated exposure to antibiotic agents favored the selection and replication of numerous strains of antibiotic-resistant bacteria. select all of the statements that accurately portray the role of natural selection in antibiotic resistance. a) when bacteria are repeatedly exposed to antibiotics, they learn how to avoid the antibiotic and survive to reproduce. b) when people overuse antibiotics, the bacteria get resistant to the antibiotic and it is no longer an effective treatment. some bacteria possess a gene for bacterial resistance. these bacteria are likely to survive a course or antibiotics and reproduce. 09 d) bacteria containing the gene for antibiotic resistance can share a plasmid of the gene with other bacteria, allowing the population of bacteria with antibiotic resistance to survive and reproduce. when someone quits taking an antibiotic when they are feeling better, they likely kill only the weaker bacteria. the bacteria with a gene for antibiotic resistance survive, giving them the opportunity to reproduce. e

c) some bacteria possess a gene for bacterial resistance. these bacteria are likely to survive a course or antibiotics and reproduce.
d) bacteria containing the gene for antibiotic resistance can share a plasmid of the gene with other bacteria, allowing the population of bacteria with antibiotic resistance to survive and reproduce
e) when someone quits taking an antibiotic when they are feeling better, they likely kill only the weaker bacteria. the bacteria with a gene for antibiotic resistance survive, giving them the opportunity to reproduce
Explanation:
When bacteria are initially exposed to an antibiotic, those most susceptible to the antibiotic will die quickly, leaving any surviving bacteria to pass on their resistant features to succeeding generations.
As in option C , bacteria possessing better gene will b selected by the nature and hence portrays Natural selection
In option d Bacteria reproduce by plasmid (extra chromosomal DNA ) transfer . Bacteria with antibiotic resistant gene with pass these genes to the succeeding generations.
When bacteria are initially exposed to an antibiotic, those most susceptible to the antibiotic will die quickly, leaving bacteria possessing gene resistant against antibiotics. Here, Darwin’s theory of natural selection comes in. This gives the bacteria an advantage over other(which do not possess antibiotic resistant gene) this bacteria will grow better than its neighbors and can increase in numbers
In option e When one quits antibiotics before completing the entire course of any prescribed antibiotic. The antibiotic resistant bacteria survives. Bacteria that are not controlled or killed by antibiotics. They are able to survive and even multiply in the presence of an antibiotic.

Inhibitors of the electron transport chain exert their effects through a variety of mechanisms.
____________ blocks electron transport and proton pumping via inhibition of Complex IV.
____________ blocks electron transport and proton pumping via inhibition of Complex I.
____________ blocks electron transport and ATP synthesis by inhibiting the exchange of ATP and ADP across the inner mitochondrial membrane.
Answer:
Azide and Carbon monoxide block electron transport and proton pumping via inhibition of Complex IV.
Rotenone blocks electron transport and proton pumping via inhibition of Complex I.
Atractyloside blocks electron transport and ATP synthesis by inhibiting the exchange of ATP and ADP across the inner mitochondrial membrane.
Explanation:
The mitochondrial electron transport chain is composed of different complexes integrated into the inner mitochondrial membrane, which function to generate an electrochemical proton (H+ ions) gradient that is then used to drive the synthesis of ATP, the energy coin of the cell. The mitochondrial complex I catalyzes the electron transfer from nicotinamide adenine dinucleotide (NADH) to ubiquinone and then transports H+ ions across the inner mitochondrial membrane. Moreover, the mitochondrial complex IV, also known as Cytochrome c oxidase, receives electrons via the cytochrome pathway in order to complete the reduction of oxygen (O2) into two molecules of water (H2O). Azide is a selective inhibitor of the complex IV which acts as an uncompetitive inhibitor with regards to O2, while carbon monoxide (CO) binds to the cytochrome c oxidase enzyme, thereby suppressing its activity and thus disturbing ATP synthesis. Rotenone is a potent inhibitor of the mitochondrial complex I that inhibits electron transfer from the iron-sulfur centers in the complex I to ubiquinone, thereby blocking ATP synthesis. Finally, atractyloside is a competitive inhibitor that inhibits the transport of ADP across the mitochondrial inner membrane by blocking the ADP/ATP translocator, thereby preventing ADP from entering mitochondria.
There is a population of alien dogs, species Dogus Cute-ee-us, that live on the planet Woof. Their genomes and biology are amazingly identical to the genomes and biology of earth dogs. Consider a di-hybrid cross, where the first locus has alleles A and a, and second locus has alleles B and b. Each additional copy of either an A or B allele in the two-locus genotype increases the friendliness of the dog. Friendliness is measured by the Wilcoxon-Canus Amicus Diagnostic Scale (WCADS). There are five categories:
0 = Unfriendly/Loner (although not aggressive);
1 = Somewhat friendly/shy;
2 = Friendly;
3 = Very friendly;
4 = Maximally friendly.
For example, an alien dog with a two-locus genotype of Aabb would have a Somewhat friendly/shy behavior, since there is one copy of A and zero copies of B, adding to a score of 1 for the WCADS. Similarly, an alien dog with a two-locus genotype of AaBB has a Very friendly behavior (one copy of A + two copies of B = three copies total of A or B).
In the following mating: AaBb x AaBb, what is the expected ratio of Maximally friendly:Very friendly:Friendly:Somewhat friendly:Unfriendly alien dogs in the offspring, assuming the parents produce a very large litter?
a. 0:1:1:1:0
b. 1:2:3:2:1
c. 1:4:6:4:1
d. 9:3:3:1
Answer:
c. 1:4:6:4:1
Explanation:
The term quantitative heritability refers to the transmission of a phenotypic trait in which expression depends on the additive effect of a series of genes.
Polygenic heritability occurs when a trait results from the interaction of more than one gene. And these genes can also have more than two alleles. The action of many genes and alleles can cause many different combinations that are the reason for genotypic graduation.
Quantitative traits are those that can be measure, such as longitude, weight, eggs laid per female, among others. In the exposed example, the measurable trait is the dog´s friendliness. These characters do not group individuals by any precise and clear categories. Instead, they group individuals in many different categories that depend on how the genes were intercrossed and distributed during meiosis. The result depends on the magnitude in which each allele contributes to the final phenotype and genotype. When they interact, they create a gradation in phenotypes, according to the level of contribution.
In the exposed example, each dominant allele contributes with a higher level of friendliness.
aabb → 0 = Unfriendly/Loner (although not aggressive); Aabb, aaBb → 1 = Somewhat friendly/shy; AAbb, AaBb, aaBB → 2 = Friendly; AABb, aABB → 3 = Very friendly; AABB → 4 = Maximally friendly.Cross: between two dihybrid friendly dogs

PLEASE HELP! I WILL GIVE BRAINLIEST. What 2 factors affect organisms and their habitats, and give examples of each
Answer:
There are two categories of these factors: abiotic and biotic. Abiotic factors are the non-living parts of the environment that can often have a major influence on living organisms. Abiotic factors include water, sunlight, oxygen, soil and temperature.
Explanation:
Biotic factors are interactions associated with living organisms. They can also influence the distribution of organisms in an ecosystem. grazing - too little leads to dominant plants outcompeting other species, too much reduces species numbers overall. Both decrease biodiversity.
Abiotic factors affect the ability of organisms to survive and reproduce. Abiotic limiting factors restrict the growth of populations. They help determine the types and numbers of organisms able to exist within an environment.
