They are diffrent by having diffrent cells like cell membrane and others because arthopods do not have back bones and mammals have back bones because we are in the mammals area because we have spines

They told me that my answer was too short so I'm just adding this on, don't mind me.
<u>Answer</u>:
1. <em>The student could increase the number of loops of wire around the iron core. </em>Increasing the number of windings will increase the strength of the electromagnet also known as the magnetomotive force.
2. <em>The student could use a bigger battery so that the voltage is increased. </em>Thus, according to Ampere's Law, the magnetic field around the current-carrying wire will also increase as it is directly proportional to the current's strength.
Answer:
Small, nonpolar molecules (ex: oxygen and carbon dioxide) can pass through the lipid bilayer and do so by squeezing through the phospholipid bilayers. They don't need proteins for transport and can diffuse across quickly.
Explanation:
The channel proteins act like doors through the cell membrane.
They allow large polar molecules to move in and out of the cell.
The process is called passive diffusion or passive transport, because it does not need energy.
Sometimes the protein changes shape to help the polar molecules move through the channel.
It often uses a gated pore mechanism, in which the channel is never completely open.
The fruit is the product of the reproduction of the flower. The fruit stores food and can help in attracting pollinators, although this is not its main job.
