Other characteristics of mollusks are:
1) Bilaterally symmetrical
2) Body has more than two cell layers, tissues and organs
3) body without cavity
4) body monomeric and highly variable in form, may possess a dorsal or lateral shells of protein and calcarous spicules.
5) has a nervous system with a circum-oesophagal ring, ganglia and paired nerve chords
6) has an open circulatory system with heart and aorta
7) has a pair of kidneys
8) reproduction normally sexual and gonochoristic

The virus has very high spread and can be transmitted through aerosol spread thus speaking, coughing, sneezing, etc can spread it very quickly. It’s also quite a slow acting virus and can take over two weeks to show symptoms making it even easier to spread as the carrier doesn’t know they have it until it’s sort of already too late. Usually when viruses get like this the most effective way to eradicate them is to develop effective treatment and vaccination. Treatment helps to stop the effects of the virus and allow the body to fight it off and vaccines help prevent the virus as well as allow the body to develop certain levels of immunity to the point where if an individual does catch the virus they are able to fight it off more effectively and with decreased risk of mortality or long term and permanent side effects of the virus.
Well here's an image of the things that do occur (different phases). You can see which ones are are right in the answer choices and pick out the wrong one. I hope this helps...
A red hot horseshoe. It have to be hot
The answer to this question would be because phospholipid is polar has <span>a </span>charge.
Since phospholipid is polar, it can attract molecule with a charge. That will cause the molecule cant move easily pass the membrane. The hydrophobic molecule doesn't have charge, so the molecule can pass through the phospholipid membrane if it small enough.
