1. The heterotrophic bacteria depends upon other organisms for food to survive. Thet can't prepare their own food.
Advantages
. If the ancestral cell having a heterotrophic bacterium as an endosymbiotic, evolution may further results a heterotrophic organism. It had heterotrophic mode of nutrition.
2. In photosynthetic bacteria, the mode of nutrition is autotrophic. It can produce it's own food.
Advantages
. If the ancestral cell having a photosynthetic bacterium as an endosymbiotic, the evolution may results a photosynthetic organism. It had the ability to do photosynthesis. If the pigments present in the organism is capable of doing photosynthesis efficiently, it can produce it's own food.
what is the advantage to an ancestral eaukryotic cell of having 1. a heterotrophic bacterium as...
Endosymbiosis is an evolutionary theory that explains the origin of eukarvotes and suggests a specific order in which this might have occurred. Ancestral cells enguited and then began to use the metabolic processes of the smaller cells. Based on shared core processes and features, which statement most accurately describes the order, the theorY and the evolutionary implications for all organisms within domain Eukarya? OAll ancestral eukaryotes would have most likely consumed a nucleus-ike prokaryote that eventually became the eukaryotic nucleus....

Which of the following does not describe plants? a) Photosynthetic b) Eukaryotic c) Cell wall made of cellulose d) Non-motile e) Heterotrophic 3. Which of the following is a characteristic of fungi? a) Photosynthetic b) Motile c) Mostly unicellular d) Prokaryotic e) Cell wall made of chitin
1) A spherical mammalian cell of radius ‘R’ is infected by a single coccus bacterium having 100 times smaller radius. Given that the host cell will lyse when 1/2 of the cell volume is taken up by the bacterium, approximately how many times will the bacterium divide before the host cell is lysed? Options : 1. 19 2. 3X105 3. 106 4. 40 2) Two experiments were conducted with an enzyme following Michaelis Menten kinetics at substrate concentrations of 0.5...
1. Hypothesize in what type of environments it would be advantageous for a protist to be autotrophic, heterotrophic, or mixotrophic. 2. Many algae are photosynthetic, like plants. Why then are they not classified as such? 3. Some protists are colony forming. Hypothesize why this may be an advantage or disadvantage. PLEASE TYPE ANSWERS
A student is examining a bacterium under the microscope. The E. coli bacterial cell has a mass of m = 1.10 fg (where a femtogram, fg, is 10−15g) and is swimming at a velocity of v = 4.00 μm/s , with an uncertainty in the velocity of 1.00 % . E. coli bacterial cells are around 1 μm ( 10−6 m) in length. The student is supposed to observe the bacterium and make a drawing. However, the student, having just...

1. The eukaryotic cell is thought to have arisen through an intimate association of an ancestral “pre-eukaryote”and a prokaryote. Briefly... Name one energy yielding pathway the “pre-eukaryote” would have been using to generate ATP prior to its association with the prokaryote. 2. Describe the process of primary endosymbiosis. 3. With reference to your description in part 2 above, name and describe two types of evidence that eukaryotic cells arose by endosymbiosis.
