Mitochondria and chloroplasts likely evolved from engulfed bacteria that once lived as independent organisms. ... Eukaryotic cells containing mitochondria then engulfed photosynthetic bacteria, which evolved to become specialized chloroplast organelles.
The answer is prokaryotes
Answer: transporting substances in a cell
Why: In eukaryotic cells, endomembrane system refers to the set of membranes present inside the cytoplasm which form single functional and developmental unit. The membranes are either connected directly or indirectly and exchange material with the help of vesicle transport. The main function of this system is to modify, pack and transport the proteins and lipids in and out of the cell. The main organelles which form the endomembrane system are- nuclear membrane, endoplasmic reticulum, Golgi apparatus, lysosomes, and vesicles.
Answer:
The correct answer is "the bottleneck effect".
Explanation:
The bottleneck effect, also known as a population bottleneck or genetic bottleneck, is defined as sharp reduction of a species population that occurs either by environmental effects or as a consequence of human activities. The dramatical crash the that population of American bison had due to hunting and other problems is an example of a species suffering the bottleneck effect.
A facultative anaerobe.
Explanation:
Anaerobes are organisms which can produce energy via the process of fermentation in the absence of oxygen. The anaerobes can be classified as facultative anaerobes and obligate anaerobes.
Facultative anaerobes are those which can carry out respiration in presence of oxygen but can choose to follow the fermentation pathway if oxygen is absent. Fermentation also uses glucose.
Aerobic respiration produces 32 molecules of ATP from one molecules of glucose while fermentation produces only 2 molecules of ATP . Thus when the organism switches to fermentation pathway it utilizes more and more glucose to reach its energy demands.
Considering all the above points we can conclude that observations indicate that the organism is a facultative anaerobe.
It seems that you have missed the necessary options for us to choose from, but anyway, here is the answer. When Melissa is studying a Gram-stained slide of curd bacteria, she <span>sees many rod-shaped, violet-colored bacteria and the type of bacteria are they are LACTOBACILLI. Hope this answers your question.</span>
