Answer:
Cold water can hold more dissolved oxygen than warm water. In winter and early spring, when the water temperature is low, the dissolved oxygen concentration is high. In summer and fall, when the water temperature is high, the dissolved-oxygen concentration is often lower.
Explanation:
Bacitracin blocks the transport of nag and nam across the cytoplasmic membrane to the cell wall. Like other antimicrobials that block cell wall synthesis, this would result in weak cell walls and cell lysis. Antimicrobilas that act by inhibiting cell wall synthesis include beta-lactams, vancomycin and cycloserine and isoniazid and ethambutol among others. They prevent bacteria from increasing amount of peptidoglycan, they have no effect on existing peptodoglycan layer and therefore are effective only for growing cells.
The correct answer is: separation of interlocked circular DNAs.
Conservative site-specific recombination is a type of site-specific recombination process that enables genetic recombination between DNA molecules. The two DNA molecules that exchange their parts contain short DNA sequences, which are bound by specific recombinase proteins. In this process, breakage and joining occur at two special sites, one on each participating DNA molecule. Depending on the orientation of the two recombination sites, conservative site-specific recombination can rearrange DNA in a form of DNA integration, DNA excision, or DNA inversion.
Answer: D. Water will move across the cell membrane in both directions because the concentrations of solute particles inside and outside the cell are the same.
Explanation:
Explanation:
The organ can become more and more weak, until it is unable to effectively send blood around the body. The blood tends to back-up in the body and fluid passes into the tissues, this leads to swelling. This congestion is the reason heart failure is often called congestive cardiac failure
