Processes such as changes in orbital geometry or volcanic eruptions have clearly affected climate in the past, and these explain
docker41 [41]

Answer:

TRUE

Explanation:

There has been a constant increase in the earth's global surface temperature. This global rise in temperature is due to the increasing number of volcanic eruptions on earth's surface, changes in the orbital geometry as well as due to the introduction of the industrial revolution, that has been taking place on earth for the last 200 years.

The eruption of volcanoes leads to the release of a large number of pyroclastic materials and greenhouse gases and volcanic gases such as CO₂, SO₂, H₂O, H₂S and many other gases, which is harmful to the atmosphere. This leads to an increasing amount of temperature, resulting in the melting of the glaciers in the polar region.

Over this long time, plate motions have rapidly taken place, due to which the volcanoes were formed and erupted near the convergent and the divergent plate boundaries.

Thus, the above-given statement is true.

If you are testing traits for Mendelian inheritance, how do you calculate the EXPECTED values?
Georgia [21]

n a cross between two heterozygous individuals, the offspring would be expected to show a 3 : 1 ratio. For example, in Case 1, three-fourths of the individuals would have red (wild-type) eyes, and one-fourth would have sepia eyes.

If there are 44 offspring, how many are expected to have red eyes?

We expect three-fourths to have red eyes.
<span>34</span> of 44 = 33

If there are 44 offspring, how many are expected to have sepia eyes?
<span>14</span> of 44 = 11

Now you are ready to calculate chi-square.
