the true fact about cilia is that Cilia, flagella, and centrioles. Cilia and flagella are projections from the cell. They are made up of microtubules , as shown in this cartoon and are covered by an extension of the plasma membrane. They are motile and designed either to move the cell itself or to move substances over or around the cell.
The genotypes for the parents should be RR and rr. I hope this helps!
A signal cascade is a series of chemical reactions which are triggered by a stimulus acting on a receptor that is then transduced to the intracellular space through second messengers. Finally, effector molecules receive the signal causing a cellular reaction to the initial stimulus. A signal cascade is very useful because it facilitates and accelerates the communication between cells that could be in different parts of a living organism. This communication is vital for cell processes in complex multicellular organisms.
A. theory because it is an explanation that is supported by extensive observations, experimentation, and reasoning.
Explanation:
Evolution can best be described as a theory because it is an explanation that is widely supported by extensive observations, experimentation and reasoning.
Theories are formulated after careful observation into a particular phenomenon.
- Most theories provides a vivid explanation into an observed event or process.
- The theory of evolution is one of such theories that suggests that an organism changes in order to adapt to its environment.
- Some of the key figures who contributed to the study of evolution are J. B Lamarck, Charles Darwin, Williams Smith e.t.c
