During periods of intense exercise, cells do not receive enough oxygen to perform the normal process of aerobic cellular respira

tion.
As a result, the cells resort to anaerobic respiration, which produces only 1/20th of the energy produced during the aerobic process. This alternative version of cellular respiration produces lactic acid as waste, which results in muscle soreness. Which of the following statements does the above information support?
a. Cellular respiration is affected by temperature.
b. Cellular respiration is affected by cell hydration.
c. Cellular respiration is affected by the availability of reactants.
d. Cellular respiration is affected by sugar production.

Answer:

c. Cellular respiration is affected by the availability of reactants.

Explanation:

No doubt the cell has less availability of oxygen (reactant). When the oxygen cannot be efficiently pumped to cells for proper cellular respiration to occur the respiration shifts to anaerobic that produces lactic acid as waste and soreness occurs. If cell has a sufficient amount of oxygen the cellular is no more effected.

Answer:

The answer is C.)

Explanation:

Cellular respiration is often influenced by reactants. In this case, the reactants are oxygen and glucose with the aim of producing ATP. At the beginning of exercise, oxygen supply reduces steadily triggering an increase in ventilation (increased breathing). Glucose stored in the muscles are also depleted, triggering glycogenolysis (break down of glycogen from the liver to make more glucose available). During intense exercise, the body cannot cope with a great increase in oxygen demand and therefore resorts to anaerobic respiration to produce energy for exercise. On the other hand, looking at option a., Temperature can affect the rate of reaction , but as long as reactants are available, the reaction will still continue.

ziro4ka [17]

Answer:

Complete question:

We are trying to determine the possible modes of inheritance for some particular human disorder. We have a very small pedigree for this disorder. Assuming the pedigree is accurate, indicate which of the six modes of inheritance are consistent with this pedigree: Select one or more Y Linked Autosomal Recessive Autosomal Dominant X-Linked Dominant X-Linked Recessive We are trying to determine the possible modes of inheritance for some particular human disorder. We have a very small pedigree for this disorder, Assuming the pedigree is accurate, indicate which of the six modes of inheritance ere consistent with this pedigree Select one or more X-Linked Recessive Y Linked Autosomal Recessive X-Linked Dominant Autosomal Dominant.

Answer:

After the analysis of this pedigree, it is clears that the inheritance pattern is X linked because the offsprings are affected with parents genotgype

Explanation:

The inheritance is X linked dominant because of the presence of one dominant gene for the affected genotype in male.

The male individuals are affected. This is therefore not a recessive inheritance in later case, it is only when the two genes are present at the same time the affected genotype will be seen.

Which is an example of an insertion mutation that changes all of the amino acids that follow the mutation?
astra-53 [7]

Answer:


2) CAG - TTC - ACG mutates to CAG - TTC - ACC - ACG

Explanation:

Insertions are mutations in which extra base pairs are inserted into a new place in the DNA. The number of base pairs inserted can range from one to thousands!

In option no. 1: We see that there is not addition of a single or more than one base, but the new base sequence is different from the original sequence at three places i.e: TTA - CAC - G

In option no. 2: The insertion of three bases ACC has been made exactly after TTC, the whole sequence and arrangement of bases remain same except this insertion.


In option no. 3: The first base of the sequence T is replaced with A, and all other sequence is same. This type of mutation is called substitution in which one base is replaced by other.


In option no. 4: The last base of the sequence C is deleted, and is not present in new sequence. This type of mutation is called deletion in which a base is removed from the sequence.


Conclusion: Therefore, the best option is 2, in which whole codon is inserted in the DNA base sequence.
