Which statement represents an abiotic environmental factor in an ecosystem?
sukhopar [10]

Answer:

An example of an abiotic factor within an ecosystem is the air temperatures in the mountains.

Explanation:

In an ecosystem, abiotic factors refer to all those non-living elements, which depend on chemical and physical elements. Water, soil, wind, temperature, climate, minerals and soil pH are abiotic elements.

In comparison to the other statements, the one that corresponds to an environmental abiotic factor is the air temperature in the mountains, describing even two factors, <u>air and temperature</u>.

<em>     The other alternatives, lion hunting the gazelle, flower growing on the vine or fish swimming in the lake represent </em><em>biotic</em><em> or living elements of an ecosystem.</em>

After the experiment the students noticed that the potato stick with the lowest mass was soft and floppy. Explain why the potato
Savatey [412]

Answer:

When a potato chip is put into salt water, the potato cells become flaccid (soft and floppy). This is because there is a higher concentration of water molecules inside the potato cells than outside. If more water enters the cell, it becomes turgid. This is important in supporting plants.

A report on the structure of the plasma membrane and its role in maintaining the cell
ycow [4]

<em>The structure of the plasma membrane is to protect the cell from its surroundings. The plasma membrane is composed of a bilayer of phospholipids, with their hydrophobic, fatty acid tails in contact with each other. The landscape of the membrane is studded with proteins, some of which span the membrane. Some of these proteins serve to transport materials into or out of the cell. Carbohydrates are attached to some of the proteins and lipids on the outward-facing surface of the membrane. These form complexes that function to identify the cell to other cells. The fluid nature of the membrane owes itself to the configuration of the fatty acid tails, the presence of cholesterol embedded in the membrane (in animal cells), and the mosaic nature of the proteins and protein-carbohydrate complexes, which are not firmly fixed in place. Plasma membranes enclose the borders of cells, but rather than being a static bag, they are dynamic and constantly in flux</em>.
