The FedEx of the cell are the vesicles.
Vesicles are the structures in which many cell materials are packed and transported. Vesicles are cellular organelles that are composed of a lipid bilayer and they function as cellular envelopes to transport cell materials from one place to another inside the cell.
An example of one material is protein. After a particular protein has been synthesized in the ribosomes of the cell, it is packaged in a vesicle called a transport vesicle. The vesicle carries this package to the Golgi apparatus for final tweaking after which it is again repacked in a new vesicle which transports it to its required destination in the cell.
Answer:
This is because fluids have a polar nature, so they couldn´t cross the lipidic bilayer that constitutes the plasma membrane
Explanation:
Plasma membranes are contituted by lipid bilayers. These kind of compounds are hidrophobic (they reject water) and don´t permit the freely passage of hidriphilic molecules that can disolve in water, constituing fluids. Because of that cells developed transport mechanism like endocytosis.
Explanation:
Natural selection is the mechanism that is responsible for the evolution of organisms.
In the given case, the Freshwater shrimp has been introduced to a pond in which the two species with variations are introduced.
The <em>C. cantonensis </em>is brighter in color whereas the <em>C. multidentata</em> is mottled drab in color. The predator fish can feed easily on the species which is brighter therefore <em>C. cantonensis</em> is more susceptible. The mottled drab species is not easily predated by the species.
The 30 % offsprings of <em>C. cantonensis</em> can survive till the reproductive age whereas 75% of C. multidentata. This shows that natural selection has acted on the color of the shrimp species selected against the predator fish species.
The species with mottled drab color is the result of the differential reproductive rate.
Answer:
if i'm not mistaken it's the nucleic acid.
c. run faster is the correct option
Primates have large brains and dexterous limbs. Non-primates have small brains and inflexible limbs. The main differences between primates and non-primates are the size of the brain and the flexibility of the limbs.
Humans are primates and are a diverse group containing about 200 species. Monkeys, lemurs, and apes are our cousins, and we have all evolved from a common ancestor over the last 60 million years.
Primates: Humans, apes, monkeys, chimpanzees, gorillas, baboons, and orangutans are examples of primates.
Non-primates: Birds, reptiles, amphibians, and some mammals are not primates.
