Answer:
<em><u>A. Neither the subjects nor the researchers can bias the results.</u></em>
Explanation:
As described, a double- blind study is one in which the researcher and his study does not know the person receiving the actual treatment.
Researchers can be bias in their studies as they seek to establish and fine tune results in the way the best favors them. A double-blind study helps to bridge this gap to prevent bias that might be introduced into an experimental set up or while interpreting results.
Answer:
b. a fluid-mosaic of phospholipids and proteins
Explanation:
According to the currently accepted structure, the cell membrane is made up of two layers of amphipathic phospholipids in which proteins are embedded or present. The hydrophobic tails of phospholipids make the core of the membrane. These tails are not covalently attached to each other and are free to move laterally. Likewise, the protein molecules float in the fluid bilayer. This mosaic pattern is not static since the positions of the proteins in the bilayer are constantly changing. The fluid mosaic model to explain the structure of the cell membrane was given by S.J. Singer and Garth L. Nicolson in 1972.
Down syndrome, turner syndrome, Klinefelter syndrome, and fragile X syndrome.
Most of the seismic activity on Earth is found on (or near) the boundaries of tectonic plates. Earth's lithosphere is divided into a number of fragments, known as tectonic plates and these plates are in constant motion.
Answer:
These pellets are not eliminated as feces, but are regurgitated through the mouth. Pellets are not found exclusively within the owl families. There are many species of birds known to regurgitate pellets: hawks, eagles, kites, harriers, falcons, and even robins are some of the more familiar ones.
tell me if im wrong :/
