Infections spreading:
Infections are caused by bacteria, virus and other microscopic organisms. They spread through droplet (sneezing etc), they can spread through blood contact (used needles that are re-used), direct physical contact (skin infections), stool (germs from excretion) and contaminated objects.

How people fight off disease:
We have antibodies in us that fight off invading cells that contain foreign bodies. Our immune system secretes these antibodies and these antibodies will fight off the infection. The time it takes for the infection to be eradicated depends on the strength of your immune system and whether you have been vaccinated.

Natural disaster:
Natural disaster such a tsunami's and earthquakes can contaminate water supplies. In tsunami's the water from the sea will go into the drinking water which isn't safe because it could cause diseases such as cholera to spread. Earthquakes disrupt sewage structures. If these are broken, water regulation would not be as good so we end up drinking dirty water, which could also be contaminated with cholera!

Wow that was long, hope it helped! :)

the correct answer is: b. pantala flavescens, because these organisms would have a high level of genetic variation due to sexual reproduction.

because involves two organisms (parents) whose genetic material combines, sexual reproduction leads to genetic variation in new generations of offspring. the offspring is an unique organism, with new genome, more protected with the higher ability to adapted. this process is fundamental to evolution.

Well i had the same answer, so the correct answer would be a. but in this case it would be the one with plasma membrane and cell wall circled that is next to the hairy pill type of thing.

The empty trna moves off and picks up another matching amino acid from the cytoplasm in the cell. the anticodon of the trna, with its attached amino acid, pairs to the codon of the mrna, which is attached to a ribosome. this sequence is repeated until the ribosome reaches a stop codon on the mrna, which signals the end of protein synthesis. the ribosome forms a peptide bond between the amino acids, and an amino acid chain begins to form. when a second trna with its specific amino acid pairs to the next codon in sequence, the attached amino acid breaks from the first trna and is bonded to the amino acid of the second trna.
