The cell cycle is the period of time from the beginning of one cell division to the beginning of the next.
The cell cycle is the series of biological events which cells go through as they grow and divide. The cell cycle has two phases.
(i) Mitosis
(ii) Interphase.
Interphase is broken down to G1 which is growth phase, S which is Dna synthesis phase and G2 which is growth phase again. In Mitosis it consists of anaphase, telophase, prophase, and metaphase.
The cell cycle begins in cytokinesis and ends in Mitosis. Mitosis cannot start before interphase ends because mitosis requires a lot of energy and nutrients to go through the process.Since interphase is the beginning of G1,Dna synthesis and G2 comes to play, it helps to create nutrients and energy.
Let’s have an example of a menstrual cycle. You bleed at the beginning of a cycle not at the end. The first day of your period is the menstrual cycle.
Let's take the example of touching something hot:
there's sensory nerves in all our body, including our hands and fingers. When a finger touches something hot. a nerve impulse will be born due to the stimulus and will be transmitted from the sensory nerves in the finger to the CNS (central nervous system)
The CNS will integrate the information, then transmit nerve impulses through the motor nerves which goes to the muscles of the finger (which are skeletal muscles) to order them to contract, to avoid the contact between the finger and the hot thing. (the same map for the blinking eye)
Well a,b and c are plants
