Based on the pedigree that is shown above, how to describe Fred?
slavikrds [6]

Answer:

The given pedigree analysis shows sex-linked trait where the female work as a carrier and have X linked recessive gene that is X^{h} and the male is normal.

So, Fred will be a male with X^{h}Y gene and Fred will be affected with X linked disease which is carried by female.

If,  X^{h} gene in the female (Ann)  act as a carrier of hemophilia and the male (John) is normal, then Fred will be a male affected with hemophilia (sex linked disease).

Hence, Fred will be affected male with  X^{h}Y genotype.

Influenza is an acute human viral disease that causes brief cellular damage followed by healing and complete clearing of the vir
Oksana_A [137]

Answer:

Influenza is caused by a lytic virus while Hepatitis C is caused by a non-lytic virus.

Explanation:

The lytic cycle for reproduction enables the virus to make several copies of itself and destroys the host cell in the process. Many bacteriophages (viruses that infect bacteria) adhere to the lytic cycle. During the lytic cycle, once the virus has attached itself to the host cell, it injects its DNA into it. The virus is thus able to use the host cell's machinery to synthesize proteins and replicate itself.

Hope that answers the question, have a great day!

If you were to use an adult cell’s nucleus with intact DNA from a Tasmanian tiger to replace the nucleus of a Tasmanian devil’s
balandron [24]

Answer:

The organism would be genetically almost similar to Tasmanian tiger.

Explanation:

DNA is the genetic material and is responsible for heredity. The DNA present in the nucleus of an egg cell contributes genetic traits of the mother to the progeny. It imparts the progeny some of the genetic traits of the mother.

In the given experiment, DNA from the Tasmanian tiger was introduced into the egg cell of the Tasmanian devil and the transgenic egg cell was allowed to produce a new progeny. Since the implanted transgenic egg cell carried the genetic information from the Tasmanian tiger, the resultant progeny would be almost similar to a Tasmanian tiger.

What are some possible future changes in the global climate?
Ugo [173]

The most probable future changes in the global climate are:

- Global warming;

If the levels of CO2 and methane increase enough in the atmosphere to be able to intensify the Greenhouse effect, than some portion of the ice on the planet will melt because of the rising temperatures, thus lifting up the sea level, creating more unpredictable weather with larger and stronger storms, but also making the mainland much drier. This would be a scenario if the continents are arranged like they are now, but if there isn't a sufficient mass of land on and around the poles, than all of the ice will melt and the sea levels will rise so much that the planet will come in the ''water planet'' scenario, and it will have wet tropical climate pretty much everywhere on the planet.

- Ice Age;

If there's a disruption in the warm ocean streams and some of them disappear, or the levels of nitrogen or oxygen increase in the atmosphere, the Earth will start to cool off, thus coming to a situation of an Ice Age. In this kind of situation, there will be large ice sheets on and around the poles that are stretching much further towards the lower latitudes, as well as mountains all over the world that are covered in snow and shaped by glaciers.
