Answer:
B There will be blue colonies only
Explanation:
This screen in called the blue white screening. This is a rapid test that allows scientist to check for their insert of choice in the colonies at a glance. The concept is that where the insert is located the <em>lac Z </em>gene in the vector is interrupted and therefor Xgal, a reporter can be produced. Where there are blue colonies being formed the plasmid has self-ligated and the <em>lac Z</em> gene is not interrupted and the X-gal can be formed rendering a blue color.
Answer: choice c
Explanation: choice a and choice c are very similar, but the phrasing of the words is different. Genes are made up of DNA.
Answer:
because California is located on the San Andreas Fault
Explanation:
California is one of the states that have higher seismic activity because it lies on an individual fault known as the San Andreas Fault. Faults are regions where two tectonic plates are moving with respect to one another, thereby they are prone to suffer earthquakes. The San Andreas Fault is a continental fault that extends approximately 800 miles (1,200 kilometers) through the US state. Conversely, earthquakes in North Dakota are uncommon because this state is located in the middle of a tectonic plate. The last earthquake in North Dakota had a magnitude of 3.3 (Richter Scale) and it happened almost 10 years ago (2012), in Williston.
Answer:
The answer is C, 40,000.
Explanation:
You can obviously tell that 400 is too low... that's one meal for all of the turtles! They would need 40,000 minnows because it's a stable number. They can reproduce, and keep the population up. 4,000, though, is too low because they wouldn't have enough time to reproduce and continue to keep the population alive. Therefore, 40,000 should be a stable population.
