2. 2,3-bisphosphoglycerate is an allosteric inhibitor of oxygen binding to hemoglobin. a. Acclimatization to high altitude involves numerous physiological and biochemical changes, including an increase in the concentration of 2,3-bisphosphoglycerate in red blood cells. Explain why the 2,3 bisphosphoglycerate concentration increases at high altitude. b. The 2,3-bisphosphoglycerate concentration in maternal red blood cells also increases during pregnancy. Why
Answer:
A. At high altitude, increase in 2,3-bisphosphoglycerate (BPG) ensures that enough oxygen is delivered to the tissues despite the low oxygen saturation levels there.
B. An increase in 2,3-bisphosphoglycerate (BPG) is necessary during pregnancy as it ensures that both the pregnant woman and developing fetus have enough oxygen for their metabolic needs.
Explanation:
Atmospheric pressure is low at high altitudes with the result that oxygen molecules in the air are further apart. The reduction of oxygen availability in the air thus reduces the oxygen saturation in the blood and brain. Oxygen saturation levels refer to the extent hemoglobin is bound or saturated to oxygen.
2,3-bisphosphoglycerate (BPG) is an allosteric inhibitor of oxygen binding to hemoglobin. At low concentration, oxygen delivery to tissues is low while at hgh concentrations, oxygen delivery to tissues increases. It ensures that oxygen bound to hemoglobin in blood from the lungs is delivered to the tissues. Thus, at high altitude, increase in BPG ensures that enough oxygen is delivered to the tissues despite the low oxygen saturation levels there.
B. During pregnancy, there is a significant increase in oxygen demand. This is due to a 15% increase in the metabolic rate and a 20% increased consumption of oxygen as the developing fetus obtains nutrients and oxygen from the mother's blood.
An increase in 2,3-bisphosphoglycerate (BPG) is necessary during pregnancy as it ensures that both the pregnant woman and developing fetus have enough oxygen for their metabolic needs.

4. The age of the Canyon Diablo meteorite was determined by
A) carbon-14
B) uranium-235
C) hydrogen-3
D) potassium-40
Answer:
B) uranium-235
Explanation:
The age of the Canyon Diablo meteorite was determined by potassium-40. Therefore, the correct option is option D.
Before entering Earth's atmosphere, the Canyon Diablo meteorite is thought to have weighed about 300,000 tonnes. It was most likely a component of the asteroid belt that lies between Mars and Jupiter. The Canyon Diablo meteorite is frequently linked to the Asteroid 1 Ceres, one of the biggest bodies in the asteroid belt. The Canyon Diablo meteorite is notable in particular for the effect it had when it collided with the Earth's surface. The Barringer Crater, which has a diameter of roughly 1,200 metres and a depth of 170 metres, was generated by the collision.

Explanation:
Leigh's disease is a mitochondrially inherited disease with symptoms that include seizures, fatigue, impaired reflexes, breathing problems, and ataxia. The pedigree shows the presence of Leigh's disease in three generations. Individual 4 had two daughters and one son, and individual 6 had one daughter and two sons. Which of the individuals indicated are affected by Leigh's disease
About the question:
You will find the pedigree in the attached files
Answer:
individual 4 → Affected woman → Black circleindividual 5 → Affected woman or man → Black circle or squareindividual 7 → Healthy woman → Empty circleindividual 10 → Affected boy → Black SquareExplanation:
Mitochondrial inheritance is the transmission of a disease or a trait from the maternal line.
Most of the DNI is in the nucleus, but there is also DNI in mitochondria. Sperm cells hardly transfer mitochondrial genes to the progeny, so mitochondrial DNI is mostly inherited from the maternal side. If there exists any mutation in this mitochondrial DNI, the whole progeny of the mutated woman will be affected, as they will get the mother genotype carrying the mutation. On the contrary, if an affected man is carrying a mutation in mitochondrial DNI, non of their descendants will get the disease.
Before answering the question, let us remember the pedigree symbols.
Squares represent Males/Men Circles represent Females/WomenEmpty symbols represent healthy/non-affected individualsSolid black symbols represent sick/affected individualsIn the exposed pedigree, we can see that the mother is affected by the disease (individual number 2), so all her children are also affected (individuals 4, 5, and 6) because the disease is mitochondrially inherited.
Individual 3 is a healthy man, so individual 4 must be an affected woman (Black circle). As she is the one affected, then all her children will also be affected. This couple had one boy and two girls. Individuals 8 and 9 are girls (circle), so individual 10 must be the affected boy (black square).
On the other hand, individual 6 is an affected man (black square), son of individuals 1 and 2. This man couples with a woman, and they have all healthy children. So this woman (individual 7) must be healthy. Even though the man is affected, all their children are not because their mother (7) is not. Remember that sperm cells do not transmit the mitochondrial genes to the progeny.
And finally, individual number 5 might be either a man or a woman. In any case, this person is also affected by Leigh's disease.

Gonorrhea and Antibiotic Resistance
The CDC has categorized several infectious agents based on the seriousness of their antibiotic resistance. Neisseria gonorrhoeae, the causative agent of gonorrhea, is one of several agents in the "Urgent Threat" category. Gonorrhea is also the second most common reportable disease in the United States. This makes gonorrhea a significant public health concern. Please locate this article through an online search engine: Kirkcaldy RD, Harvey A Papp JR. et al. Neisseria gonorrhoeae Antimicrobial Susceptibility Surveillance - The Gonococcal Isolate Surveillance Project, 27 Sites United States. 2014. MMWR Surveill Summ 2016;65/No SS-7):1-19. DOI: http://dx.dol.org/10.15585/mmwr.ss6507at. Read the article thoroughly, and then answer these questions about the agent of gonorrhea and its potential for antibiotic resistance. eBook erences
Select all of the characteristics below that apply to Neisseria gonorrhoeae. (NOTE: Please change all question marks to checkmarks for correct answers or empty boxes for incorrect answers.)
a. It is a virus.
b. It usually affects the urogenital system but may also affect the eyes.
c. It is a gram-positive bacterium.
d. It must be grown on selective and enriched media.
e. It is gram-negative bacterium.
f. It can cause asymptomatic infections.
g. It usually affects the nervous system.
h. It is a yeast.
Answer:
b. It usually affects the urogenital system but may also affect the eyes.
e. It is gram-negative bacterium.
d. It must be grown on selective and enriched media.
g. It usually affects the nervous system.
f. It can cause asymptomatic infections.
Explanation:
Neisseria gonorrhoeae is a gram negative bacteria known to cause the sexually transmitted infection called Gonorrhea. Gonorrhea is easily treated with antibiotics, as long as the patient seeks early care and discovers the disease early on, as it can be asymptomatic, especially in women. When left untreated, Neisseria gonorrhoeae can infect the nervous system, causing many problems and even leading to death.
Despite being known to attack the urogenital system, this bacteria can attack the eyes generating gonococcal conjunctivitis, which is also sexually transmitted.
Neisseria gonorrhoeae is a fastidious bacteria, which means that it only grows in specific, selective and enriched culture media.
