Due to a rise in global sea level, a shallow sea covered most of eastern Virginia during the Cretaceous. Virginia had drifted north from the equator and conditions no longer supported the formation of limestone. The tropical climate disappeared, replaced by more temperate conditions. In place of limy sediments, sand and silt were deposited as the sea level receded in the region we now know as the Plateau region. Under these conditions, we would expect to find more fossils of ____________ life forms in this location.
A) marine
B) primitive
C) single-celled
D) terrestrial

D) terrestrial////////////////////

In pea plants, tall (T) plants are dominant over short (t) plants. If a heterozygous (Tt) pea plant is crossed with a homozygous dominant (TT) pea plant, all of the resulting pea plants should be tall (TT or Tt). Each plant will receive a dominant allele from the homozygous dominant plant, while they could receive either a dominant or recessive allele from the heterozygous plant.

The fact that each plant gets only one allele from each parent plant is detailed in the law of _______.
A.
genetic inheritance
B.
multiple alleles
C.
independent assortment
D.
segregation

4. The “Dust Bowl” event of the 1930s occurred in what Region of the United States?

5. The mass soil erosion that occurred during the Dust Bowl event was caused by several contributing factors. Choose all that influenced this strategy

[ ] severe drought was affecting the entire region
[ ] wild herds or buffalo over grazed the plains
