What kinds of particles must diffuse through a membrane via passive transport, or facilitated diffusion?

Biology

Facilitated diffusion therefore allows polar and charged molecules, such as carbohydrates, amino acids, nucleosides, and ions, to cross the plasma membrane. Two classes of proteins that mediate facilitated diffusion are generally distinguished: carrier proteins and channel proteins.

semi anThe bones of a prehistoric man found in the desert of New Mexico contain approximately 5% of the original amount of carbo
Kitty [74]

Answer:

24555 years

Explanation:

Data provided in the question:

Half life of carbon 14 = 5700 years

carbon present in the dead man = 5% of the original amount of carbon 14

Now,

let the initial Amount of carbon be 'A'

Therefore,

after half life

Amount of carbon = \frac{A}{2}

Thus,

\frac{A}{2} = Ae^{kt}

here,

k is the decay constant

t is the time = 5700 years

therefore,

1 = 2e^{k\times5700}

or

0.5 = e^{k\times5700}

taking natural log both the sides

-0.69314 = 5700k

or

k = - 0.000122

therefore,

for dead man Amount of carbon = 5% of A = 0.05A

thus,

0.05A = Ae^{( - 0.000122)t}

or

0.05 = e^{( - 0.000122)t}

taking natural log both the sides

we get

-2.995 = - 0.000122 × t

or

t = 24555.18 ≈ 24555 years

What are the parts of the aminote egg?<br><br> Select from the drop-down menus to label a, b, and c.
lianna [129]

Answer:

the chorion, the allantoids, the amnion and the yolk sac.

Explanation:

The amniotic egg has four layers. All of these layers are enclosed by a shell

The chorion helps for gas exchange. It's the layer that covers the whole embryo

The allantoid is a sac that helps with gas exchange but also is the one that encloses the wastes of the embryo during the development into the egg, one analogy is with the garbage bag, where all the waste is lookup

The amnion is the layer that protects the embryo, is like a jacket that surrounds the embryo

The yolk sac is the one that has the nutrients that are necessary for the embryo throughout all the development. It is like a lunch box for the embryo
