In a classic episode of Star Trek, a gigantic amoeba engulfs an entire starship. Spock blows the cell to bits before it reproduces. Think of at least one problem a biologist would have with this particular scenario.
Considering which organelles were created through the endosymbiotic theory, which of the following is NOT something that the host could receive from the engulfing a symbiont?
A.
the engulfed cell provided the host cell with adenosine triphosphate (ATP)
B.
the host cell was able to survive anaerobic conditions with the engulfed cell alive
C.
the engulfed cell provided the host cell with carbon dioxide
D.
the engulfed cell allowed the host cell to metabolize glucose
I have a pet amoeba. It's name is Stretch. I look at stretch every day with my microscope, feed it, play with it, etc., like any good pet owner
would. But one day, I notice that Stretch is really stretching out! And a few minutes later, Stretch has turned into two. Amoebas reproduce
through mitosis, where they replicate all of their internal biology, then split themselves into two, each new cell carrying everything it needs to
survive.
Which one is Stretch? Both? How can that be, since things are only identical to themselves? We wouldn't call identical twins the same person,
even though they are very similar to one another. Are neither Stretch? One but not the other? How would we determine that? Explain whatever
it is that you think is true, and back it up with some reasoning. Be sure your response is at least 300 words. Like usual, find a classmate that you

The evolution/development of the skeletal system found in the Deuterostomes, is made up of two molecules, Ca+2PO4-2 and collagen These molecules are produced released from by a specialized type of stem cell. Therefore, one would expect that these stem cells perform which of the following a) the storage and the release of Ca+2PO4-2 and collagen from vesicles from the Golgi apparatus, b) high levels of protein synthesis c) active transport of amino acids and ions…arrow_forwardThe cells labeled A came from my (Riva's) cheek.

A dormant cyst form of the microbe infects human hosts through fecal-oral transmission if they come in contact with hamster droppings and don’t wash their hands before eating. The organism exhibits active, motile morphological forms at other stages of its life cycle. Sexual reproduction (fusion of haploid gametes) occurs in the hamsters; only asexual reproduction occurs in humans. It has a nucleus, but does NOT have a cell wall.
