A microbiologist obtained two pure biological samples: one of a virus, and the other of a viroid. Unfortunately, the labels had

been lost. The microbiologist felt she could distinguish the two by analyzing for the presence or absence of a single molecule. What molecule would she search for and why?

The researcher could look for the presence of proteins, because viruses have a envelope (capsid) composed of proteins that involve their genetic material. The capsid may have a helical or icosahedral structure and is extremely regular. Viroids cannot synthesize any type of protein, so differentiation is possible.

What adaptations of the wild yak enable it to survive in the alpine biome?
elixir [45]

The alpine biome is one of the coldest biomes on the planet, it is generally because of the high altitudes. The summer temperature varies in between -12 to 10 degree Celsius, and the average precipitation in the biome is about 30 cm in a year.  

The animals living in the region, adapt to the cold by migrating to warmer regions, hibernating, or insulating their bodies with the help of fat and fur layers. Their bodies seem to possess shorter tails, legs, and ears, in order to minimize the loss of heat.  

One of the animals living in the alpine biome is the wild yak, the animal has adapted to the biome with the help of dense and wooly coats, specially amended feet, horns to dig for food, and if necessary does the migration in winter times to the warmer regions.

irga5000 [103]

Protein denaturation results in a disruption of the secondary and tertiary structure.  A denatured protein does not have the function it previously had. Some proteins owe their functions to the three dimensional shape they have; what is responsible for holding the shape of a protein is the R-group interactions.

If an object has a mass of 20 kg, what is the force of gravity acting on it on earth? A. 196 N B. 32.67 N End of exam C. 1.96 kg
Tems11 [23]
We have to find the force of gravity of an object that has a mass of 20 kg and then to choose the correct answer. The formula for the force of gravity is: F = m * g, where m is the mass of an object and g is the acceleration of the gravity ( on Earth : g = 9.81 m/s^2 ). F = 20 kg * 9.81 m/s^2 = 196.2 N, or approximately 196 N. Answer: A. 196 N<span>.</span>
