Answer:
Non Silent
Explanation:
Mutation, is generally, any change or alteration to the genetic sequence of a DNA. However, mutation can be of different types depending on how it occurs. According to this question, a mutation is said to be SILENT if it involves the substitution of a nucleotide with another nucleotide that does not change the protein molecule encoded by the gene. In other words, the mutation happens in such a way that both the original sequence of gene and the mutated one codes for the same amino acid sequence (protein).
On the other hand, a mutation is NON SILENT i.e missense or nonsense mutations, if the mutation causes a change in what amino acid the DNA strand codes for. For example, in missense mutation, a different amino acid is produced while in nonsense mutation, a STOP codon is produced.
Answer:
a. lactic acid fermentation
Explanation:
Under conditions of intense exercise, the oxygen gas obtained by pulmonary respiration may be insufficient to meet the needs of muscle cells in the work of obtaining energy from cellular respiration.
However, even in the absence of oxygen gas, our muscle cells can release the available energy in glucose, leading to even smaller amounts of ATP molecules. Under these conditions, muscle cells perform lactic fermentation, a process that is virtually identical to glycolysis (the first set of cellular respiration reactions), except that pyruvic acid is transformed into lactic acid with the formation of 2 ATPs. Despite the lower energy yield, fermentation ensures the energy supply to the muscle. Lactic acid formed under these conditions has been associated with muscle pain and fatigue characteristic of intense physical exercise. Recent research, however, has shown that pain is caused by muscle fiber micro-injuries rather than lactic acid as it is rapidly metabolized and eliminated.
Answer: The endocrine system is the collection of glands that produce hormones that regulate metabolism, growth and development, tissue function, sexual function, reproduction, sleep, and mood, among other things.
Explanation:
First, all people that contact the gym should disinfect themselves by washing their hand with soap. It would be better if they could wash their entire body and changes their cloth.
To find the best disinfectant to kill the bacteria you can take a sample and then test it with various disinfectant. The disk with lowest bacteria count will be the most effective disinfectant. Then, you should clean all the room using the chosen disinfectant solution.
An organism able to live and reproduce only in the presence of free oxygen (e.g., certain bacteria and certain yeasts). Organisms that grow in the absence of free oxygen are termed anaerobes; those that grow only in the absence of oxygen are obligate, or strict, anaerobes.
