DNA microarrays allow scientists to determine the genotype of a chunk of our genome and also measure the how the genes in that chunk are expressed. Using this technique has been essential in isolating genes that predispose people to cancers, and therefore allowing physicians to preemptively identify and monitor at-risk individuals. For instance, the genes BRCA1, BRCA2, and PALB2 have all been identified (using DNA microarrays) and linked to breast cancer. Knowing this allows individuals to seek out testing and take appropriate measures to prevent cancer/monitor the possible onset of cancer, which has proven to be life-saving.
The trapping of the sun's warmth in a planet's lower atmosphere due to the greater transparency of the atmosphere to visible radiation from the sun than to infrared radiation emitted from the planet's surface.
Cilia are found in certain a. protozoa.
In the field of biology, cilia can be described as thread-like projections which are membrane-bound, found in mammals and various microorganisms referred to as ciliates.
Protozoa are eukaryotic organisms that are single-celled. The protozoa can either live freely or choose a parasite to live in.
Cilia are present in certain protozoa in order to help the protozoa in movement. The cilia also help the protozoa in gathering food for nutrition. The cilia also make it possible for protozoa to attach to a surface. Sensations in a protozoa can also be generated through cilia.
The cilia cover the entire surface of the protozoa cell.
