Answer:
C) Viruses are not living organisms; they cannot reproduce by themselves
Explanation:
In order for a virus to reproduce they must enter a living cell thus they are not living organisms.
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.

Movement of surface currents
Explanation:
- Remote sensing is used to gather data regarding Land use-mapping, weather forecasting, environmental study, and resource exploration.
- In the case of ocean currents, only satellite remote sensors can determine ocean currents synoptically over coastal regions.
- SAR(Synthetic Aperture Radar) is also used to determine the ocean currents.
- The flow patterns of ocean currents are drafted with satellite infrared scanners.
- Usually, many oceanographers use Radio antenna and high-frequency "Radio detecting and Ranging" for measuring surface ocean currents.
B. The sperm cells swim to the egg cells through their watery surroundings.
