Answer:
Crossing over increases the genetic variation
Errors in crossover formation result in chromosomal rearrangements (duplications and deletions) and may also cause chromosome nondisjunction
Explanation:
Crossing over, also known as recombination, refers to the exchange of genetic material (DNA) between non-sister chromatids of homologous chromosomes during meiosis. Crossing over increases the genetic variation of the resulting gametes, allowing different genetic combinations to be passed from parents to offspring. Unequal crossing over is a type of error associated with chromosomal duplication and/or deletion events. Unequal crossing over occurs when homologous sequences are not paired precisely. Moreover, errors in crossing over may also cause chromosome nondisjunction, thereby leading to aneuploidies.
Answer: B. schistosomiasis
Explanation:
Swimmer's itch is also called as cercarial dermatitis. It appears as a skin rash. It is typically an allergic reaction which is caused by a parasite.
Swimmer's itch is the symptom of Schistosomiasis. It is a disease which is also called as snail fever. It is caused by the parasitic flatworm called as schistosomes. This parasite infects the urinary tract and intestine in humans. Other symptoms include the diarrhea, abdominal pain, bloody stool and blood in the urine.
Osmophiles, which means they don't spend much time in the water.
Answer:
c
Explanation:
when to objects come together and conform or conjoin they take what make the better of one from the 2 that are malleable
When the swimmer is unable to take in enough oxygen for the sprint, the ATP (Adenosine triphosphate) will be compromised. In such conditions, the body will use anaerobic respiration to produce the ATP. Anaerobic respiration takes place in the absence of oxygen. It used the electron acceptors in place of the oxygen in the respiratory cycle. The amount of the ATP produced is, however, less in anaerobic respiration.
Hence, the answer is 'Option C - Anaerobic respiration would be used to produce small amounts of ATP in the absence of oxygen'.
