Answer:
The amphipathic property of the phospholipids that constitute the membrane
Explanation:
It seems like a options-based answer so it would be better if they were included here but basically, each of those phospholipid molecules has two parts with antagonistic reactions towards water.
The head is polar or hydrophilic, wich means it can be sorrounded by water. The tail, is apolar or hydrophobic which means it is repelled by water.
The interior and exterior of the cell is contain water-based substances, that's why the heads of the phospholipids are oriented like that with the tails protected inside the membrane.
This double layer structure has a fundamental role in the fluid property of the cell membrane from which derive most of it's functions.
<span>If you examine a rock sample and observe fossils in it, the type of rock the sample represent in C - sedimentary. Igneous rock is a melted and cooled rock and there are no remains of any kind of fossils. Still, can be found some fossils traces in some metamorphic rocks with the lowest grade of metamorphism but those are very very rare.
the answer is C, sedimentary </span>
<span>Bariatric surgery is a surgery created to help one lose weight. The set-point theory says that the body’s regulatory controls help a person maintain a specific body weight as time goes on. Bariatric surgery works to establish a new set-point by altering body weight and establishing weight loss results.</span>
Answer:
PFK: cytoplasm
insulin: ER--> Golgi--> outside cell
Explanation:
As described in the question, the enzyme phosphofructokinase (PFK) functions is a cells cytoplasm. Enzymes are proteins and proteins are made in the ribosomes of a cell. As ribosomes are present in the cytoplasm, hence PFK once made in the ribosomes will be released into the cytoplasm.
As for insulin, it will be made in the ribosomes. from there, it will move to the Endoplasmic Reticulum for packaging. Then to the Golgi complex for modifications and further packaging. Only after these stages, it will be ready to move out from where it is produces to areas where it has to be used.
Answer:
Convergent Evolution
Explanation:
Convergent evolution occurs when two unrelated species that have no common ancestor evolve independently in order to adapt to a similar environmental constraints to ensure survival.
An example of convergent evolution can be seen in birds, bats, flight/wing insects. They all do not share a common ancestor, but have evolved, separately, a similar structure for flight.
Another example can be seen in dolphins and sharks. These two different species share similar physical characteristics that make them adapt well in marine habitat that helps them to predate
