What happens to the abundance of angiosperm and gymnosperm pollen fossils at the kt boundary?
dimaraw [331]
The KT boundary marks a mass extinction event. the KT boundary is the time between the Cretaceous and Tertiary periods. An asteroid hit the earth at the end of the Cretaceous and that caused the end of the Cretaceous period. Before the KT boundary, pollen from angiosperms and gymnosperms is high. After the meteor hits the earth, a mass extinction occurs and the amount of pollen from gymnosperms and angiosperms decreases dramatically, while the amount of spores from ferns increases. During the Cretaceous period there were many species of gymnosperms and angiosperms but they disappeared at the KT boundary, when the asteroid hit the earth.

1.Explain how the TATA box and transcription
jeka94

Answer:

The TATA box is an alternating sequence of Adenine and Guanine nucleotides that transcription factors bind to. The TATA box is found just before a gene. The transcription factors tell the RNA polymerase where to bind to begin transcription. This ensures the RNA polymerase will know where to start and which gene to transcribe.

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.

disa [49]
The assessment activity that enabled the nurse to derive to the conclusion of "related to" factor is THE USE OF ATROPINE MOLECULE.

Atropine injection is used before anesthesia. This decreases the mucus secretion and keeps the heartbeat normal during anesthesia and surgery. In case of any allergic reaction, atropine sulfate should not be administered in the patient.
