Answer:
Confocal Microscope is used for cell structures in the micrometer range while Electron microscope is used in the range of nanometers
Explanation:
The confocal microscope makes use of optical sectioning in order to achieve a thin section with the sample still intact. It is used for cells or structures inthe micrometer range such as the lisosomes. The lisosomes in a cell can be tagged with a flourescence dye and they would be seen using the confocal microscope. They provide a high-resolution image with all areas in focus throughout the field of view
The Electron Microscope on the other hand requires real sections, it makes use of transmitted electrons (electrons which are passing through the sample) to create an image. It is used in a range of nanometers, with it, you can view the nanoparticles inside a lisosome.
The medial pathway, which controls gross movements of the head, trunk, and limbs, consists of tectospinal, reticulospinal and vestibulospinal tracts.
The tectospinal tract in humans, also known as colliculospinal tract, is a nerve tract that coordinates head and eye movements. This tract is a part of the extrapyrimidal system in which it particularly connects the midbrain tectim and cervical regions of the spinal cord.
The vestibulospinal tract is a neural tract found in the central nervous system. It is specifically also a component of the extrapyramidal system and is a classified component of the medial pathway. The vestibulospinal fibers of the tract relay information from the nuclei to the motor neurons which is the same with the other descending motor pathways.
Lastly, the reticulospinal tracts or the descending or anterior reticulospinal tracts are extrapyrimidal motor tracts that goes down from the reticular formation in two tracts to act on the motor neurons supplying the trunk and the flexors and extensors of the proximal limb.
Answer: Geologic time is divided into units. Major changes in the earth's surface or climate and the extinction of species help to divide the time scale into smaller units.
Explanation: Rocks grouped within each unit contain a similar fossil record.
Answer:
The dependant variable would be the fertilizer
Explanation:
The dependant variable is what the new or tested variable is.
