Answer:
Through facilitated diffusion
Explanation:
A molecule that finds it difficult to enter through the cell membrane's phospholipid bilyaer can be assisted in doing so through a process known as <u>facilitated diffusion</u>.
Ordinary diffusion will not permit the movement of molecules against a concentration gradient or molecules can be prevented from passing the phospholipid bilayer due to their sizes/charges. Within the phospholipid bilayer exists special passages lined with <u>carrier </u>or <u>channel proteins.</u>
<em>These proteins facilitate some molecules that will ordinarily not pass through the bilayer to pass through their special passages. This process is referred to as facilitated diffusion.</em>
Answer:
i'm gonna need more details to answer
Explanation:
because a glucose molecule is to large to pass through a cell membrane cells assist glucose diffusion through facilitated diffusion and two types of active transport.
Rose pollen is large and sticky in comparison to grass pollen as it has to stick to insects to cross pollenate! Grass pollen is produced in larger quantitys and is smaller and lighter than rose pollen because grass pollen is dispersed by wind!
B) Businesses might invest in places that lack environmental regulations.
Explanation:
- Certain gases in the atmosphere has the ability to trap the radiating heat from the earth and keep the atmosphere warm even during the night.
- These gases are called greenhouse gases.
- Carbon dioxide, methane etc are some example of green house gases.
- These gases are added to the atmosphere in large amounts due to burning of fossil fuel.
- Though green house gases are very important in maintaining the temperature of the Earth but if their percentage increases in the atmosphere then they may contribute to global warming.
- Global warming is a environmental havoc and is leading to global climate change and melting of ice caps.
- To manage this problem it is very necessary to reduce the increasing green house gases.
- To achieve this goal governments of various nation has formulated rules according to which, the industries that do not have efficient machinery to reduce consumption of fossil fuel and reduce green house gas emission are charged fines.
- But since these rules are not implemented in all places , the industries choose to establish business in those places where they are not forced to comply with strict environmental rules. So, there is a negative impact on the economy of the nation that have strict regulations to conserve environment.
