<span>Protein channels are needed to transport substances because it accelerates the transport process. Very few substances enter or leave cells without being attached to a transport protein. Different types of substances require different types of proteins to transport them. Protein channels transport water or ions downwards and ATP-powered pumps transport molecules or ions upwards. ATP generates energy to transport the molecules upwards. Gravity is used to transport the water molecules downwards. So, in a nutshell, if substances need to be transported from the top of the body downward, the force of gravity is used to transport the substances down. If substances need to be transported upwards, ATP, a coenzyme, is used to generate energy to transport the substance upwards</span>

Jobisdone [24]

Answer:

See the answer below

Explanation:

a) Shyam must have obtained a saturated solution of the sugar. A saturated solution is one that already contains the maximum amount of solute it can dissolve at a given temperature.

Shyam can get the sugar to dissolve in the water by

1. <u>continuously stirring the solution</u> in order to increase the entropy of the system. The more the entropy of a system, the faster the rate of reaction.

2. <u>raising the temperature of the water</u> through heating. The heat will increase the entropy of the system and cause more sugar to dissolve.

How is population size affected by limiting factors?
Tresset [83]

Answer:

How do limiting factors affect population size?

Explanation:

Limiting factors are factors that affects the size of a population and slows down its growth rate or stop it in its entirety.

These factors include food, space, temperature, sunlight etc.

Limiting factor like food can affect a population greatly like not having enough preys in a forest, therefore the predators are starved to death or even in a fish pond where there is high competition for space (overpopulated) which leads to oxygen deficiency i.e they compete for oxygen as well, and this can lead to death as well.
