The image to determine the 'component a' is not found here, but the electrophoresis device is composed of an agar/polyacrylamide gel, a chamber and poles (cathode and anode).

<h3>What is electrophoresis?</h3>

Electrophoresis is a device used in the laboratory to separate biomolecules depending on their charge and mass.

The electrophoresis device consists of an agar/polyacrylamide gel, a chamber, and two poles: cathode (positive) and anode (negative).

Electrophoresis is very useful to separate DNA molecules, which migrate to the positive pole due to their negative charge.

Look at the table you filled in above. How does the numbers for how much the snakes are consumed compare to how much these preda
S_A_V [24]

The number of organisms decreases on movement from producers to consumers in a food chain. This happens due to decreased energy levels at higher trophic levels.

<h3>What is a food chain?</h3>

Food chain is the sequence of matter and energy transfers as food from one organism to another.

Food chains interconnect locally into a food web as most organisms consume more than one type of animal or plant.

The number of organisms decreases on movement from producers to consumers in a food chain. This happens due to decreased energy levels at higher trophic levels.

Thus, it can be concluded that this is the main reason behind the number of snakes consumed as compared to other organisms.

What is embedded in the phospholipid bilayer that helps in the movement of larger molecules ?
gladu [14]

Answer:

\boxed {\boxed {\sf A. \ Channel/Transport \  proteins}}

Explanation:

The phospholipid bilayer is also known as the cell membrane. It covers cells and regulates the transport of substances. Certain ones can pass and others cannot, depending on certain factors like size and polarity.

Smaller substances tend to diffuse or move across the membrane quite easily. However, larger molecules have a much harder time. Many depend on special proteins embedded in the membrane. These are called transport proteins and they form a channel so large molecules can still move in or out of the cell.

So, salt, water, and fats do not contribute to the movement of larger molecules, but <u>channel or transport proteins do and choice A is correct. </u>

Regan is trying to determine if an unknown element is a metal. She does not want to damage or change the physical appearance of
34kurt

Explanation:

Well, one could use a magnet to see if it's ferrous. One could melt it to check which type it is, use a metal detector, or just use their senses: If it dings or clinks like metal, and feels like it’s texture. If it polishes with metal polish, is reflective, can be shaped or shape when heated… It usually is a metal. If it rusts, or oxidizes, it is or contains metal. If it “smells" like metal, most likely, it is metal. Finally, if it walks like metal, and quacks like metal, most likely we have a metal
