The answer is;
How are the organisms related?
What are molecular-level changes that are associated with
human disease?
The former applies in the field
of evolutionary biology while the latter in the field of medicine and molecular
biology. Another application of the whole
genome sequencing technology is in forensics (paternity testing and DNA matching and profiling). Also, metagenomics
that enables researchers to determine which types of microbes may be present in
a particular biome.
Answer:
The correct answer is option A. "The rate of diffusion would be faster for the right cylinder".
Explanation:
The rate of diffusion is defined as the amount of molecules that are exchanged from a body to another. The rate of diffusion is directly proportional to the ratio of surface area to volume , where the higher the ratio of surface area to volume the higher the rate of diffusion. In this case, a sphere have a ratio of surface area to volume equal to 0.3 m, and a right circular cylinder have a ratio of surface area to volume equal to 2.1 m. Since the right cylinder have a higher ratio of surface area to volume, the rate of diffusion would be faster for the right cylinder.
Answer:
1. The correct answer would be A) allow you to view living cells, while electron microscopes do not.
There are many advantages of light microscope over electron microscope such as:
- It is easy to use as compared to the electron microscope.
- It enables us to view both alive as well as dead specimen whereas electron microscope can be used to view dead specimen only.
- Light microscopes are much cheaper and have much lower maintenance cost as compared to the electron microscope.
2. The correct answer would be C) scanning electron microscope
Scanning electron microscope or SEM is a type of electron microscope which is used to observe surface topography and composition of the specimen. It can achieve resolution of up to 1 nanometer.
3. The correct answer would be 400x
The total magnification of the microscope can be calculated by multiplying the powers of the objective lens and that of the eye lens.
Thus, the magnification of the specimen would be 40*10 = 400x.
Answer:
I. High concentrations of dissolved ions in seawater.
