A channel protein serves as a tunnel across the membrane into the cell. More specifically, channel proteins help molecules across the membrane via passive transport, a process called facilitated diffusion. These channel proteins are responsible for bringing in ions and other small molecules into the cell

Explanation:
To decide which days would be okay for her team to conduct the experiment that involves, canopy fogging, here are some information and facts that we should have in mind:
1. Canopy fogging is a technique employed in the collection of insects in the study of forest insects. It basically involves the use of a chemical that would only affect only insects, such as pyrethrine.
2. A sprayer, which may be in the form of a machine is used in spraying this chemical in the form of aerosol with the aid of a blower.
3. Living insects are mostly collected this way for research and studies.
4. Canopy fogging is not usually done when the weather is windy and/or raining. Wind and rain would disrupt the effectiveness of the chemical used in fogging. Wind would blow away the tiny particles of the chemicals being sprayed. Rain may also wash away the particles, and rain might come with storms, hence wind would be present also.
5. Canopy fogging can be done in a sunny and windless weather with no storm.
<em>So therefore, </em><u><em>Monday, Saturday and Sunday</em></u><em> should be ideal days for carrying out canopy fogging since rain and/or wind are absent in these days.

Explanation:
Most diving birds have (relatively) long necks and shorts legs, although their necks aren't as long as say herons, storks or egrets. Take the common loon for instance. Their necks can be up to half as long as their bodies but their legs are so short and set so far back that they are very awkward on land.
