A bacterial cell that is resistant to a particular antibiotic may spend a large amount of energy producing the modified proteins

that are needed for resistance. In such a case, what would be the effect on this cell's fitness if no antibiotic was present?

5 0

Answer:

Its fitness would be lower than other strains that lack resistance because it is spending energy that the resistant strains can use for other purposes, such as reproduction.

Explanation:

A pharmaceutical company trying to develop a drug that improves tissue oxygenation by increasing the percentage of oxygen that is released from hemoglobin during its passage through the capillaries of extrapulmonary tissues. This drug, it is hoped, would become a popular doping agent for athletes.This means that the company should try a drug that Inhibits the degradation of 2,3-BPG( 2,3-Bisphosphoglycerate) , thereby increasing its concentration in erythrocytes

Bacterial conjugation
lord [1]

Answer:

Yes, these are correct.

Explanation:

  • Bacterial conjugation is the bacterial counterpart of sexual reproduction. Also known as horizontal gene transfer, it involves the transfer of genetic material from one F+ or Hfr bacterium to another F+ or F- bacterium.
  • The F or fertility factor is a crucial component of the bacterial plasmid and it accounts for the development of sex pili which are important for conjugation. An F+ cells contains the F-factor incorporated into its plasmid, whereas an F- cell lacks the F-factor and therefore cannot participate in conjugation.
  • Conjugation between an F+ and F- cell can result in the transfer of the F-factor to the F- bacterium.
  • An Hfr bacterium contains F-factor incorporated into its circular genome.

Explain the structure and function of the eye as a sensory receptor including the role of;
larisa [96]

Answer:

A) The cornea is the transparent outer covering of the eye,The lens is a curved structure in the eye that that bends light and focuses it for the retina to help you see images clearly.The lens works together with the cornea to focus light correctly on the retina. When light hits the retina (a light-sensitive layer of tissue at the back of the eye), special cells called photoreceptors turn the light into electrical signals.

B)The iris is the part of the eye that makes up your eye color. A circular muscle with a hole in the middle.The iris controls the amount of light that enters the eye by opening and closing the pupil. The iris uses muscles to change the size of the pupil. These muscles can control the amount of light entering the eye by making the pupil larger or smaller.

C)Rod cells are highly sensitive to light and function in nightvision, whereas cone cells are capable of detecting a wide spectrum of light photons and are responsible for colour vision.

Note - hope this is accurate :)
