ndividuals III-6 and III-7 have two little monstersand are expecting a third one. Their two childrenhave two eyes. What is the c
CaHeK987 [17]

Answer:

The correct answer is - 75% or 3/4.

Explanation:

In the given question, there is a cross between III-6 and III-7 that produced two double eyes monsters and expected one more. As given in the image that the A or single eye is dominant over the a or double eye then both parents must be heterozygous as they produced double eye offspring (aa) and they do have only one eye.

then chances of single eye offspring would be -

cross: Aa and Aa

gametes: A, a and A, a

Punnett square:

           A      a

A         AA     Aa

a         Aa      aa

so there are 75% chances to have a single eye and 25% chances for a double eye.

6. (a) What two major changes have occurred in the North Fork Toutle River?
antiseptic1488 [7]

A massive landslide Mud flows in the Toutle river.

<h3>How changes have occurred in the North Fork Toutle River?</h3>

There had been many earthquakes in the area prior to eruption but this happen to be a massive land slide because a moving magma have over steepened the mountain slopes.

This geologic process uses gravity to cause rock, soil, artificial fill or a combination of the three to move down a slope. Slow weathering of rocks as well as soil eruption and volcanic activity also causes landslides

Thus, massive landslide Mud flows in the Toutle river.

Flu vaccines need to be revised and changed every year because the flu virus constantly mutates. Flu viruses can change in two ways: drift or shift. Antigenic drift occurs when genes of the virus slowly change during replication until the immune system no longer recognizes it. On the other hand, antigenic shift occurs when a major change in the virus happens. This usually leads to a totally different kind of virus. This is what happened during the H1N1 scare in 2009.

DNA viruses like mumps are less prone to mutation due to the presence of DNA polymerase. RNA viruses are more prone to mutation because they undergo reverse transcription to simulate the role of DNA.
