Which of the following is NOT true of a reaction that breaks a bond?A. It creates low-energy products
B. It is what happens in cellular respiration
C. It is an endergonic reaction

Answers

Answer 1
Answer:

C.  It is an endergonic reaction.

Endergonic v/s Exergonic:

  • In the exergonic reaction, the reactants are at a higher free energy level than the products (reaction goes energetically downhill) while In the endergonic reaction reaction, the reactants are at a lower free energy level than the products (reaction goes energetically uphill).
  • Endergonic reactions use energy to build bonds  while Exergonic reactions release energy through breaking bonds.
  • When a bond breaks, it creates low-energy products.
  • In cellular respiration, breaking of bond happens.

Therefore, the statement which is NOT true for a reaction that breaks  a bond is option C.

Non-cardiogenic pulmonary edema is the most profound effect from exposure to

Answers

Alcohol and drug abuse, certain medications, and viral infections may lead to Non-cardiogenic pulmonary edema. Exposure to either of these could contribute or increase the chances getting Non-cardiogenic pulmonary edema.

Answer:

Non-cardiogenic pulmonary is due to anticancer therapy.

Explanation:

Noncardiogenic aspiratory edema (NCPE) is an uncommon and less well-conspicuous pulmonotoxic disorder of anticancer treatment than pneumonitis/fibrosis.  

NCPE is a clinical disorder portrayed by concurrent nearness of serious hypoxemia, respective alveolar invades on chest radiograph and no proof of left atrial hypertension/congestive cardiovascular breakdown. The analysis of medication-related NCPE depends upon recorded rejection of any irresistible, metabolic, or disease-related causes.  

The time closeness to treatment with medications that are known to hasten NCPE, any first scenes of influenza-like side effects during past chemotherapy courses and conceivable reaction to corticosteroids may further help such a finding.

Malignancy remedial specialists plainly connected with NCPE are cytarabine, gemcitabine, and interleukin-2, just as all-trans retinoic corrosive in intense promyelocytic leukemia patients, while a couple of different mixes have infrequently or every so often been ensnared. The pathophysiology of lung damage in medication incited NCPE stays misty.

A malaria outbreak causing allele frequencies to change is an example of:nonrandom mating.

the bottleneck effect.

genetic drift.

natural selection.

differential migration

Answers

Answer:

The correct answer would be natural selection.

Natural selection favors the survival and reproduction of the organisms which are better adapted to the environment.

It gradually changes the allele frequency or heritable characters of a population over the generations.

Similarly, during malaria outbreak organisms which are better adapted or resistant against the disease will survive and reproduce successfully. It will increase the frequency of allele associated with resistance or adaptation against malaria.

For example, the carriers of the sickle cell anemia show protective advantages against malaria.


The correct answer is option D, Natural selection.

The survivors within a population attacked by malarial mosquito are the individuals which have high rate of survival and reproductive rates as compared to others. The genetic qualities of these individuals have proved to be beneficial in their survival and thus their future generations consists of individuals which are able to survive in the harsh environmental conditions. This mechanism of survival of the fittest is known as natural selection.

What did Chargaff discover while studying bases in the DNA of organisms?

Answers

Chargaff found out that the ratios of thymine and adenine were equal and the ratios of guanine and cytosine were equal. He then created the Chargaff's rule states that double stranded DNA has a 1:1 ratio between pyrimidine and purine bases. With this, amount of guanine bases is equal to cytosine bases while the amount of adenine bases is equal to thymine bases.

Answer: B. The ratios of thymine and adenine were similar, as were the ratios of guanine and cytosine
