Answers
Answer:
Antibiotic resistance is a consequence of evolution via natural selection. The antibiotic action is an environmental pressure; those bacteria which have a mutation allowing them to survive will live on to reproduce. They will then pass this trait to their offspring, which will be a fully resistant generation.

(a) Describe why monitoring the growth rate of the E. Coli-M bacteria is a useful indicator of the effect of the glycolytic enzyme mutation on the bacteria.
Answers
Answer:
The monitoring the growth rate of E.Coli bacteria is a useful indicator of the effect of glycotic enzyme mutation on the bacteria as the flow of intracellular metabolic components depends on the availability of carbon. Hence the change in carbon source can change the glyclyotic enzyme mutation up or down.
Explanation:
Continuous culture is a method that can be used by the researchers for determining whether mutation affects the growth rate of E.Colin-M bacteria
If the growth medium contains higher concentration of acetate,then the growth of the bacteria will be inhibited without inhibiting its central metabolism.
When E.Coli grows ,it secrets acetate. This mechanism is called overflow mechanism. Regulatory interactions mediated by acetyl-phosphate plays a major role in inhibiting growth by acetate. The uncoupling effect of organic acids or perturbation of the anion composition of the cell is a major reason for growth inhibition.

How is it possible for a mutation not to produce any visible effect in an
organism?
Answers
Answer:
Some mutations don't have any noticeable effect on the phenotype of an organism. This can happen in many situations: perhaps the mutation occurs in a stretch of DNA with no function, or perhaps the mutation occurs in a protein-coding region, but ends up not affecting the amino acid sequence of the protein.

Your friend Joe has a younger brother Sam and two older sisters. Sam has a strange disorder that has caused his hair to turn green. The doctor says that this is caused by a single gene that is inherited, and that boys are more likely to have green hair then girls. However Joe, his sisters, and both of his parents have normal hair color. Joe does not know much biology and is confused. Explain to Joe how his brother's condition could have arisen even though Joe has normal hair. Then discuss the likelihood that a) Joe, and b) Sam will have children with green hair. Assume that they both marry women with normal hair color. You will need to include information on meiosis and transmission of genes to assure that Joe understands. HINT: As part of your answer, indicate the percent of girls vs. boys that you predict would have green hair if fathered by Joe vs. Sam.
Answers
Answer:
The correct answer is - it is due to the case of sex-linked recessive disorder.
Explanation:
It is pointed out by the doctor that Sam has a condition due to recessive allele and it is given that boys have this condition more than girls which suggests that it is a sex-linked recessive disorder. This comes from their parents but it is given that the father has normal hair which means the father has no recessive allele, then it must come from the mother even mother has not this condition but she could be a carrier for this trait.
Joe and his sister do not have this condition as they get the normal dominant allele from mother and father.
The chances of being a carrier by his sisters are 50%. If Joe marries
IF Joe marries a non-carrier woman, he will have all normal children with no green hair. IF Joe marries a normal hair color carrier women then there would 25% chances of being diseased offspring and 50% chances of being a carrier, and if women is completely normal then all offspring will be normal.
carrier woman, his children will have a 25% chance of being green-haired. A 25% chance of being
IF Sam marries a normal woman, the children will have a 25% chance of being a carrier, a 25% chance of being green-haired, and a 50% chance of being normal.

Answers
Answer:

Explanation:
So you can mark the other person :)
Anything that contains atoms emits infrared radiation. Therefore, option (D) is correct.
What is Infrared radiation?All objects, living or non-living, emit some amount of infrared radiation, which is a type of electromagnetic radiation with wavelengths longer than those of visible light. The amount and wavelength of the infrared radiation emitted by an object depends on its temperature, with hotter objects emitting more and shorter-wavelength infrared radiation.
This is the principle behind the use of infrared cameras and thermal imaging technology to detect and measure heat in a variety of applications, including night vision, medical imaging, and industrial inspections.

Why the Chimpanzee's diploid number is 24 instead of 48.
I am not sure if the following table supposes me to write 2 (N) on here...
Thank you very much
Answers
Answer:
It has 24 pairs and 48 number of chromosomes.
Explanation:
The Chimpanzee's diploid number of chromosome is 24 pairs instead of 48 because of the resemblance with the human cell that have 23 pairs of chromosome. The Chimpanzee has 24 pairs of chromosome or another words we can say that chimpanzee has 48 number of chromosomes not pairs. Humans have 23 pairs whereas apes have 24 pairs of chromosome. The theory suggested about this close number of chromosomes is that at some point two ape chromosomes fused to make a single human one.
