Prokaryotic cells have a simpler structure than eukaryotic cells.
Evidence shows that eukaryotic cells evolved from prokaryotic cells.
Some might argue that prokaryotic cells are less important than
eukaryotic cells. But a case can be made that prokaryotic cells are just
as important to life on Earth today as eukaryotic cells. Which do you
think is true? Are prokaryotic cells important to life on Earth? Analyze
the similarities and differences of these cell types to explain your
position.
why this is in my portfolio
I chose this because I
think I wrote my argument well and because if I put this in my portfolio
more people will know how awesome prokaryotes are
my answer
Answer:
Because of the great deal of active transport that occurs here, the <u>proximal convulated tubules</u> of all the nephrons collectively account for about 6% of one's daily resting ATP and caloric consumption.
Explanation:
Proximal convulated tubule is responsible for transport of a very large number of substances mentioned below :
- Sodium bicarbonate
- Sodium Chloride
- Glucose
- Amino acid
- Organic solutes
- K ions are absorbed via paracellular pathway.
- Water is absorbed passively.
Transporters include :
- Na/K transporter
- Na/HCO3 transporter
- Na/glucose
- Na/Amina acids
As a large number or transporters are present in the PCT , large amouny of ATP is cleaved here, and about 6% of daily resting ATP and caloric consumption occurs.
Answer:
This assertion is false since it depends on the type of selection exerted on the trait under investigation
Explanation:
Geographic isolation is caused by physical barriers such as, for example, rivers, mountains, longer distances, etc, which prevent the interchange of genetic material among populations of the same species. Over time, complete geographic isolation leads to genetic isolation among populations and the development of reproductive barriers, resulting in the separation in two species (speciation). Intermediate populations prevent speciation by enabling gene flow among populations. In consequence, intermediate populations often exhibit intermediate traits as a consequence of bidirectional gene flow; however, there are cases where a given trait is favored by non-directional selection, thereby favoring phenotypic values exhibited by marginal populations localized at the extreme distributional range of the species.
