( Endocytosis / Exocytosis ) is the movement of substances out of a cell by vesicular transport.
tiny-mole [99]

Answer:

Exocytosis

Explanation:

Some molecules are simply too big to move via a transport protein or the plasma membrane. To carry these macromolecules in or out of the cell, cells employ two more active transport pathways. Macromolecules or big particles are transported across the plasma membrane via Vesicles transport or other cytoplasmic structures. They are of two types, Endocytosis and Exocytosis

From the given information, Exocytosis is the right answer.

It is the process of vesicles combining with the plasma membrane thereby releasing their contents to the exterior of the cell. When a cell creates components for export, such as proteins, or when it gets rid of a waste product or a toxin, exocytosis occurs. Exocytosis is the process by which newly generated membrane proteins and membrane lipids are transported on top of the plasma membrane.

A 32.8 g iron rod, initially at 22.4 C, is submerged into an unknown mass of water at 63.1 C, in an insulated container. The fin
laila [671]

Answer:

mass water = 32.4 g

Explanation:

specific heat iron = 0.450 J/g°C

specific heat water = 4.18 J/g°C

32.8 x 0.450 ( 59.1 - 22.4) + mass water x 4.18 ( 59.1- 63.1)=0

541.7 - mass water x 16.7 = 0

mass water = 32.4 g

The glancing angle (θ) of a Bragg reflection (n = 1) from a set of crystal planes separated by 99.3 pm is 10.42°. Calculate the
Rufina [12.5K]

Answer:

wavelength λ =  35.92 pm

Explanation:

Given that:

The glancing angle (θ) = 10.42°

Bragg reflection n = 1

wavelength λ = ???

diameter d = 99.3 pm

Using the formula:

nλ = 2dsinθ

we have:

1 × λ = 2 × ( 99.3) × sin (10.42°)

λ =  198.6 × 0.18086

λ =  35.92 pm
