Note: Question is Incomplete i have added full question in picture format. And marked correct answers.
Answer:
This question is about antibiotics resistance development in bacteria over time. Resistance develop only when we overuse these antibiotics. Resistance development in bacteria lead to their exponential growth resulting in more infections.
Also See attachment for full question and answer.
The true statements are:
A. Because the population grew more rapidly after time point C, the bacteria must have acquired a second drug- resistance mutation.
C. Bacteria that acquired a mutation that conferred drug- resistance had a growth advantage over non-resistant bacteria.
D. Between time points C and D, drug-resistant bacteria were reproducing faster than non- drug resistant bacteria were dying.
Oxidative phosphorylation relies on the hydrogen ion concentration gradient generated and maintained by the electron transport chain.
Hydrogen ions are actively transported out of the mitochondrial matrix.
Hydrogen ion concentration is higher in the intermembrane space than in the mitochondrial matrix.
Answer:
e. is mostly asexual, with sexual as a second option.
Explanation:
Protist are unicelluar eukaryotic microorganims. Example include:
<u><em>Amoeba</em></u> <u><em>proteus</em></u>
<u><em>Euglena</em></u><em> </em><u><em>viridis</em></u>
Dinoflagellates, etc.
Among the species of Protists, each species exhibit a unique way of reproduction. Generally, in Protist there are two types of reproduction, these are asexual reproduction and sexual reproduction. With asexual reproduction being the primary mode of reproduction in most protists.
Protist reproduce asexual by binary fission or by budding.
Binary fission occurs when a single protist divides its nucleus and then divides itself into two separate organisms.
Budding occurs when a new organism grows from the body of the parent organism. The new organism may separate from the parent or remain attached, forming colonies.
They also reproduce sexually by conjugation.
Sexual reproduction by conjugation requires two parent organisms contributing to the genetic material of the offspring. The essence of conjugation is to produce a new offspring with a wider genetic variability i.e the offspring being genetically different from the parent organisms.
I think so but im not positive
hope it helps
