The answer is B hope this helped!
Using the thick blood film to detect malaria enables observation od parasite morphology and it is used to quantify and identify parasites to the species level. For that kind of detection a high-power microscope (400 times to 1,000 times magnification) is required. The microscopist can look for parasites in a relatively large volume of blood, thus increasing the sensitivity of the test.
There are bacteria, like the Pseudomonas fluorescens and Marimonas protea, that can reside even in frozen surfaces. They do it by entering a dormant state where they wait patiently to be free from ice and grow again.
Bacterial adaptation to cold surroundings also involves changes in their membrane composition and translation and transcription machinery. This includes bacterial conjugation.
The answer is A.
