Answer: Water erosion

A scientist observes the ocean tides moving large amounts of sand away from the beach is a evidence for natural process which is known as water erosion. Water erosion is a process of removal or detachment of  upper soil layers from its's original place due to the effect of water. The rate of erosion may be rapid or slow depending upon the soil, the landscape and weather conditions. The beach exhibit sandy soil whose particles are not connected or aggregated with each other and not with the surface over which it is present. Therefore, sand being loose soil is taken away by oceanic tides due to water erosion.

Allen pours water into a graduated cylinder. He notices that the surface of the water is curved, as shown below.
Slav-nsk [51]

Answer:

When water is added to a graduated cylinder, having a surface where the sides of the water look higher than the center means that the curved surface is a concave meniscus which has formed because of surface tension (Choice C).

Explanation:

A meniscus is simply the curvature that the surface of a liquid acquires when it is in a container, such as a graduated cylinder. It is concave when there is attraction between molecules -water and glass- or it can be convex when both surfaces are repelled.

<u>Water is a polar molecule</u>, with the capacity to adhere to the surfaces it comes into contact with. This characteristic causes it to form a concave meniscus, as the outermost molecules adhere to the glass surface, while the surface tension of the water attracts the molecules from the centre downwards, causing the concavity.

Contact [7]

According to the research, the correct answer is fiber composites. Because cell walls consist of a cross-linked network of long filaments embedded in a stiff surrounding material, they can be called fiber composites.

<h3>What are cell walls?</h3>

It is a network that covers prokaryotic cells and plant cells that is located outside the plasma membrane, helping to form the structure.

In this sense, since it is made up of a network of carbohydrates, phospholipids and structural proteins, and the different cell types of plants can be identified by their characteristics, they can be called fiber composites.

Therefore, we can conclude that cell walls are a network embedded in a matrix composed of carbohydrates and proteins.

Which answer best explains the difference between protists and bacteria?
Delvig [45]

Answer:

The correct option is A. Bacteria are prokaryotes and protists are eukaryotes

Explanation:

The major difference between BACTERIA AND PROTISTS is the Bacteria are PROKARYOTES in nature and they dont have what we called nucleus reason been that their microbes are single celled microbes while protists on the other hand are EUKARYOTIC in nature and they have nucleus and they can either have a single-celled or have more than one celled.

The Second difference is that protists can only be found in the area or surrounding that are mostly moisture while bacterial on the second hand can be found in every area, environment or surrounding.

Therefore the answer that best explains the difference between both protists and bacteria

Is option A which states that Bacteria are PROKARYOTES while protists are EUKARYOTES.

Which part of the earth system interacts with solar flares?
ss7ja [257]
The magnetosphere interacts with solar flares. It helps to redirect them. Otherwise, the Earth would be greatly heated and human life would become much harder to sustain, as homeostasis would require better cooling mechanisms.
