On average, an adult male sea otter weighs 36 kg (79 pounds), with some individuals weighing as much as 45 kg (99 pounds). A female weighs an average of 23 kg (50 pounds). To maintain their weight, otters must consume 250 kilocalories/kg of body weight each day to survive. Otters eat almost entirely small invertebrates for which they must dive to catch.

You have been tracking an adult female otter who weighs 25 kg. Answer the following questions based on the data provided.

How many kilocalories must she consume each day to maintain her body weight?



Question options:

6,250 Kcals


275 Kcals


1,620 Kcals


9,000 Kcals

Answer:

the answer that i would presume is a

Explanation:

25 x 250

The female otter which weighs 25 kg must consume a total of 6,250 kilocalories per day in order to maintain her body weight.

According to the illustration, otters must consume 250 kilocalories per kg of body weight in order to survive.

A female otter that weighs 25 kg must, therefore, eat 25x of the recommended kilocalories per kg daily in order to main her weight.

Thus: 25 x 250

                    = 6,250 kilocalories

Two colleagues that share the same office are exposed to the flu virus one week in January. Janet just recovered from the same flu virus two weeks earlier, while Mark has not been sick yet this winter. Which person do you expect would be more likely to become sick with this flu virus and why?

Janet: since she already had the flu, her immune system is weaker than Marks.

Janet: she will most likely get the flu again, and a more severe case of it.

Mark: he has not acquired any active immunity to the flu, and Janet has.

Mark: he has only passive immunity to the flu which will not benefit him in this case.

Answers

I believe Mark is more likely to get sick with the flu virus because Janet has acquired a slight immunity because she was infected with it while Mark has not been infected with the virus

3.We anticipate our recombinant DHFR protein to be functional for use in future research applications. However, if you had been able to test functionality and found that your recombinant GST-DHFR-His protein was not functional, what would you propose is one potential issue you would investigate to troubleshoot further. In other words, what is one thing that could have gone wrong to result in non- functional protein from the method used and results obtained this semester

Answers

Answer:

In the given case, the protein would have required to go through the process of post-translational modification, however, the mentioned protein would have been cultured in the prokaryotic system, the process of post-translational modification would have failed to take place. This step would be essential for the functionality of the protein. Thus, there is a need to culture it within the eukaryotic system.

The covalent and generally the enzymatic modification of proteins post its biosynthesis is termed as post-translational modification.
