Answer:
Henry observed <u>ecological diversity</u>.
Explanation:
Ecological diversity can be described as the variations which are present among different ecosystems and how these variations impact the life on Earth. The differences present in the aquatic and terrestrial ecosystems are defined by the ecological diversity.
As Henry is observing the differences in the aquatic life as well as the terrestrial life, hence he is studying ecological diversity.
Ecological diversity is a type of biodiversity i.e diversity of all the living components of ecosystems.

Explanation:
Answer:
Antibiotic resistance is when pathogens such as bacteria or fungi develop a resistance to antibiotics. This happens when some pathogens die, and others survive. The small number of pathogens that had a resistance to the antibiotic will reproduce more offspring that are also resistant to, and those offspring will reproduce even more offspring and so on. Eventually most pathogens will be resistant to the antibiotic, so antibiotics won't work.
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.
