Answer:
1. The chi-square statistic is 0. The p-value is 1. Not significant at p < .05.
The chi-square statistic with Yates correction is 0.0642. The p-value is .800028. Not significant at p < .05.
Explanation:
2. By generating large sets of data the ratio will remain same (F1 = 3:1, F2 = 9:3:3:1) according to the Chi-Square analysis. In actual reality, it fails to justify by giving a probability value of 1 that is impossible due to the exceptions of Co-Dominance and Incomplete Dominance...
B
Vaccinations protect people when they are exposed to the microorganism to which they were vaccinated. This secondary response happens when the person is exposed to the microorganism. At that time, IgG production is a lot higher, making it the main antibody class in the second response. IgM is more active when it comes to the first exposure. A lot of people who have allergies have IgE in their bodies, too. IgA is the most common secretory antibody, and it stops pathogens from attaching and invading through the mucosal membranes of the body.

Answer:
The correct option is <em>3. they break down rock into soil in which plants can grow</em>
Explanation:
When a disaster is such huge that even the soil and organic matter get removed from the place, then the succession that will occur in such kind of place will be termed as primary succession. For example, a volcanic eruption or an earthquake.
On the other hand, if after a disaster some of the organic matter remains on the land, then the succession that will occur will be termed as secondary succession. E.g a succession after fire
In primary succession, the pioneer species will be plants that require less soil such as the lichens. The lichens will break down the rocks into the soil and eventually new species of plants will start to grow on the land.
