1) Muscle Cell*myosin filament: changes shape and pulls on and releases actin filament allowing movement*If the myosin filament was missing or injured, it would be cause difficulty in movement2) Flagellum*Dynein arms: uses energy from ATP to "grab" the attached droplet allowing a wave like movement when pulling the droplets together* If the dynein arms was missing or injured the flagellum would have no possible way of moving causing it to stuck in mid-air
Ex. Air freshener.
simple diffusion is the process of a substance (such as air freshener) moving from high concentration to low concentration with little to no energy.
DNA is the main type of genetic material found in a cell. In addition, it is found in the nucleus of the cell, so (D) is correct. DNA in the nucleus is used in replication (through mitosis and meiosis) via daughter cells to continue cell growth.
Answer:
False.
Explanation:
Monohybrid cross may be defined as the cross done by taking the single character at the time. The monohybrid cross explains the concept of dominance and law of segregation.
The P1 parent of monohybrid cross doesnot have completely identical genes. This can be explained by the cross shown below:
Parent Tt × tt
Gamete T t × t
Here, the parents are not identical.
Thus, the answer is falsi.
