1. Stockroom tools: this includes:
Beaker: this is essential to take or storing small substances
Bunsen Burner: this is important in the biological lab to heat a substance
Flask: this is essential in holding liquid substance.
Pipette: it forms of a lab spoon that is used in mixing substances to form a compound or mixture
2. Computer and Imaging system: this is important in image analysis and sequence-analysis programs
3. Cell cultures: this is used in the biological lab to enhance the complex cell differentiation required in the experimentation of animal cell structure
4. Microscopes: this is essential in determining and examining the microscopic organism that we can not see with our makes eyes
Answer:
Parabolic dunes
Explanation:
A parabolic dune is a U-shaped mound of sand. The tips point upwind because they are anchored by vegetation.
A is wrong. The tips of a barchan dune point downwind
C is wrong. A longitudinal dune is parallel to the prevailing wind.
D is wrong. The ridge of a transverse dune is perpendicular to the prevailing wind.
A minimum stream velocity <span>needed to keep a 6.4 cm diameter particle in motion must be 100 cm/s.
It can be concluded from Hjulstrome curve, a graph used to determine whether stream will transport, erode or deposit particles. The faster is the current, the heavier particles it could transport.</span>
