Tetanus
Tetanus is an acute bacterial
infection caused by the Clostridium tetani bacterium. It is
characterized by muscle spasms. The bacteria enter the body through a deep cut
or wound. The early symptoms of this infection include diarrhea, fever, and
headache. Other symptoms include sweating and rapid heartbeat.
Answer:

Explanation:
a figure of speech in which a word or phrase is applied to an object or action to which it is not literally applicable.
Answer: Principle of Original Horizontality.
According to the principle of original horizontality all rock layers are horizontal in nature and this is specific to sedimentary rocks. The younger sediments remains in the top layers and older ones remains at the bottom. These sediments accumulate in horizontal and parallel layers and becomes compact to form rocks in the end.
1- Preparing the cDNA:
a- Using two different tissue samples (such as control and cancer cells), isolate mRNA.
b- For each sample, prepare complementry DNA (cDNA) from the isolated mRNA. Then fluorescent label cDNA of each sample with a different color and then mixed.
2- preparing the microarray:
a- Bind DNA fragments of different genes to microarray wells.
b- Attach ssDNA (single-stranded DNA) to microarray wells.
3- Combine the probe and the microarray samples:
Add labeled cDNA to the microarray wells.
Similarities:
Both move from a region of high concentration to a region of low concentration through a partially permeable membrane.
Differences:
Facilitated diffusion is for any small particles which can pass through a partially permeable membrane while osmosis is only for water molecules.
