An adaptation in the stigma that helps with fertilization is the ability of pollen grains to germinate on this structure. It allows plants to reproduce.

An adaptation can be defined as a type of trait that allows organisms to survive and reproduce in particular conditions.

Adaptation favors the process of natural selection, which involves differential survival and reproduction.

Moreover, stigma is a plant structure that receives pollen grains (male gametes) during fertilization.

Answer:

hi there, proteins are related to DNA  because DNA carries the instruction for synthesizing  proteins, which can code for a certain amino acids based on the sequence.

Explanation:

A change in  base sequence can be either good or bad. But... Usually... a mutation could be a main factor that changes the sequence of the protein, which causes it to code for a different amino acid than the original. Base pairs could either substituted,  deleted, or inserted, which usually are what a mutation could be caused by or consisted of. This is also known as a gene mutation, which are changes in genes .

Answer:

3.31 atm.

Explanation:

Gay-Lussac's law states that for a given mass and constant volume of an ideal gas, the pressure exerted on the sides of its container is directly proportional to its absolute temperature.

∵ P α T.

∴ P₁T₂ = P₂T₁.

P₁ = 3.00 atm, T₁ = 20.0 °C + 273.15 = 293.15 K.

P₂ = ??? atm, T₂ = 50.0 °C + 273.15 = 323.15 K.

∴ P₂ = (P₁T₂)/T₁ = (3.00 atm)( 323.15 K)/(293.15 K) = 3.307 atm ≅ 3.31 atm.

Ion channels are specialized proteins in the plasma membrane that provide a passageway through which charged ions can cross the plasma membrane down their electrochemical gradient. The resulting ionic current, generated by the movement of charged ions through membrane channels, can be measured by patch-clamp methods.

Ion channels must be able to interact with the charged regions of the cell membrane so nutrients can enter the cell.

Ion channels are passages in the cell membrane that allow the passage of charged molecules such as

Ions pass from one side to the other of the cell according to the electrochemical gradient. In other words, they go from a place with high concentration to one of low concentration. But to do this, they need to interact with the charged regions of the membrane, which are the ion channels.
