Answer:
The 10X objective is use for the identification of actual size of histology tissues and 4X magnification is best for observation of most tissues slides
Explanation:
4X magnification is best for observation of most tissues slides because it has an objective lens that have lower power and have great high field overview which make it very easier to locate specimens on the slide. It is use to get the overview of histology slides. It is use to showcase more detailed observations about histology.
The 40X objective is use majorly to identify tissue , to observe the finer details and study tissue organization on the histology slide.
Answer:
Potential energy
Kinetic energy
Gravitational energy.
Explanation:
The potential energy is the stored energy, it is the energy and object posses at rest. When the base jumper is still at rest i.e without motion, she has potential energy.
Gravitational energy this refer to the potential energy an object or body with mass posses in relation to another object due to gravity.
This is seen when the base number is still at rest and the force of gravity on the Earth acting on her.
Kinetic energy is the energy posses by an object or body in motion.
As the base jumper falls to the ground, she posses kinetic energy which is the energy in motion.
Answer:
B. 1 m/s
Explanation:
Metric unit conversions:
0.3 km = 300m
5 minutes = 5*60 = 300 seconds
So if a seal can reach a depth of 300m in a time of 300 seconds, its diving speed is the distance divided by time duration
v = s/t = 300/300 = 1m/s
So B is the correct answer
