Division of labor is essentially when tasks are divided and carried out by specific parts. This occurs in cells, where different tasks are distributed among different parts, referred to as the organelles. For example, the mitochondria in the cell produce energy to carry out cellular activities. The nucleus is involved in cellular division and other genetic functions. In such a manner, the "labor" that a cell has to perform is divided among its organelles.
The invention of the electron microscope opened up many doors for biologists as it helped them to view and learn the appearance of cells and their sub-cellular structures
<h3>What is an electron microscope?</h3>
Electron microscope are microscopes which helps biologists to view the appearances of cells of organisms which cannot be seen with our nak -ed eyes.
Generally, electron microscopes:
- Uses a beam of accelerated electrons as its source of illumination
- Helps in obtaining high resolution images of biological and non-biological specimens.
- It is also used in biomedical research
In conclusion, electron microscope helps biologists to view, learn and to also understand the appearance of cells and their sub-cellular structures

#SPJ1
Of lower concentration and higher concentration
Answer:
Metabolic processes that require oxygen are called aerobic. Metabolic processes that do not require oxygen are called anaerobic.
Explanation:
Um I just looked it up
Answer:
Channel proteins form hydrophilic channels to passively transport substances down the concentration gradient.
Carrier proteins bind to substances to transport them actively against the concentration gradient. They do not form channels.
Explanation:
Channel proteins are the membrane proteins that serve in transport of small polar molecules and/or ions by making a hydrophilic pore across the membrane. These molecules diffusion through the pore and exhibit facilitated diffusion.
Carrier proteins are the membrane proteins that transport the substances across the membrane by binding to them. They do not form the hydrophilic channels. Carrier proteins serve in the active transport of molecules against the concentration gradient.
