Most probably the right choice for this is <u>A. extraembryonic membranes</u> because this is known as the structural adaptation in chickens that allows them to lay eggs in arid environments rather than in water.
The four extraembryonic membranes that surround the chick's embryo are the chorion, which helps with gas exchange, the amnion, which encloses amniotic fluid, the yolk sac, which protects the yolk, and the allantois, which helps with waste removal and gas exchange.
Physical traits that have evolved on chickens through time in order to help them live and reproduce are called structural adaptations.
Over time, the hens that are more well-adapted to their surroundings survive and breed more consistently, causing their genes and adaptations to be passed down to future generations of chickens.

A prokaryotic cell does NOT have a membrane. Eukaryotic does on the other hand. A great example of a Prokaryotic cell is bacteria.
Hypertonic environment
<h3>
How do salts and sugars preserve food?</h3>
Salts and sugars work to preserve foods by creating a hypertonic environment. Salt and sugar will remove the water from the bacteria or fungi and they will not be able to proliferate. Loss of water results in plasmolysis, or cytoplasmic shrinkage.
<h3>What is hypertonic solution and plasmolysis?</h3>
Compared to another solution, a hypertonic solution has a higher solute concentration.
Plant cells subjected to hyperosmotic stress frequently exhibit plasmolysis as a reaction. The live protoplast violently separates from the cell wall as a result of the loss of turgor. The vacuole is primarily responsible for the plasmolytic process.

#SPJ2
Answer:
A number of reactions may occur simultaneously in groundwater and cement-based materials, including the dissolution of portlandite that is generated from the intrusion of hydrogen ion, the increase of the concentration of calcium in the pore solution, formation of ettringite by sulfate attacking the cement, and the dissolution of Calcium–Silicate–Hydrate (CSH) gel by chloride entering the cement, and the formation of Friedel’s salt
Explanation:
Distillation, Filtration, evaporation, and Chromatography
The filtration process is generally used to separate a suspension mixture where small solid particles are suspended in liquid or air.
Distillation uses boiling to separate mixtures of liquid solutions. It takes into account that different substances in the mixture will have different boiling points..
Chromatography is the separation of a mixture by passing it in solution or suspension or as a vapor (as in gas chromatography) through a medium in which the components move at different rates
Evaporation is a technique used to separate out homogenous mixtures where there is one or more dissolved solids. This method drives off the liquid components from the solid components
