I would say individual biodiversity. I have read that there are variations in genes so genetic variation is a biodiversity along with species diversity and ecosystem biodiversity. In fact, genetic diversity is similar to species diversity. Species have their own genetic variation.

True. We are losing biodiversity at a higher rate than ever before.
A subsurface rock layer that is composed of clay and bedrock and is an impermeable barrier to water flow would be described as a(n) <u>aquifer(option b)</u>.
An aquifer is an underground layer of water-bearing permeable rock, rock fractures or unconsolidated materials (gravel, sand, or silt).
The study of water flow in aquifers and the characterization of aquifers is called hydrogeology. Aquifers occur from near-surface to deeper than 9,000 metres (30,000 ft).
There are three different types of aquifers: confined, unconfined, and perched. Recharge zones are typically at higher altitudes but can occur wherever water enters an aquifer, such as from rain, snowmelt, river and reservoir leakage, or from irrigation.

I think two are stem cell research and cloning
Distance/Time = 120 Km/2 hours =120/2 Km per hour or for short 60 Km per hour
Glucose and galactose are bond together in the molecule, and lactase assists in the process of separating them through a mechanism called hydrolysis. In lactose a water molecule is inserted across the glucose-galactose bond, adding an oxygen and hydrogen to the galactose.
