For many generations, the following genotypic frequencies were observed in a large population of dinosaurs: 4 percent AA, 32 per
Usimov [2.4K]

Answer:

C) 19.7%

Explanation:

The new population distribution after climate change wiped out homozygous recessive dinosaurs is:

AA = \frac{4}{4+32}=\frac{1}{9}

Aa = \frac{32}{4+32}=\frac{8}{9}

The percentage of offspring of this new population that are homozygous recessive is given by:

P(Aa\ x\ Aa) = \frac{8}{9} *\frac{8}{9} =\frac{64}{81} \\P(aa) = \frac{1}{4}\\P(Aa\ x\ Aa) \cap P(aa) = \frac{64}{81}*\frac{1}{4} =0.197=19.7\%\\

19.7% of these newborn dinosaurs died

Leokris [45]
Best Answer: Well, you have to look at the onion slide under the microscope and looks at each cell and tell what stage (interphase, prophase, etc.) they are in. and then for the description probably tell which one there is the most of and maybe why you think that is. You can find pictures of each phase in your book. I did a lab like this not too long ago in my bio class lol. And, i believe that you will get a lot in interphase (when cells are not currently dividing), just to let you know.

How does water's specific heat relate to its usefulness for life give examples?
RideAnS [48]
<span>Water covers around 70% of the Earth's surface and its high specific heat plays a very important role as it is able to absorb a lot of heat without a significant rise in the temperature. When temperatures decrease, the heat which is stored is released, restraining a rapid drop in temperature. The combined effect of these processes is a buffering of temperature on the Earth.</span>

Feliz [49]

Answer:

The correct answer is option b. "it has high face validity".

Explanation:

Face validity in a test is a very broad concept that simply refers to whether the test appears to be suitable to report what it claims to do. It is important to notice that high face validity in a test only means that the judgers of the test agree that the test is suitable, but it doesn't mean that the test is reliable for the patient and for the therapist. In this example, Kristoff should take other tests and examinations before he could be sure that he is not suffering from depression, particularly because he has many symptoms that indicate that he is depressed.
