Answer:
a cell that has half the number of chromosomes as the parent cell
Because they need to make a cell a haploid cell which only has half of the total number of chromosomes.
Chloroplast is what help the plant get sunlight and it gives the plant color so if u took this out the plant wouldn't get proper sunlight and wouldn't have much color.
A zygote is the product of fertilization. The diploid zygotes of the four organisms seen here all underwent Mitosis and differentiation in order to produce the four very different embryos. In mitosis cell divison occur in which mother cell divide to form two daughter cell . When we talk about the cell differentiation , it is the process in which cell changes from one form to another.
Answer:
The reflex arc follows this sequence of events
1. sensory receptor activation
2. sensory neuron activation
3.information processing
4. motor neuron activation
5. effector response
Explanation:
Reflex arc is the pathway of nerves during a reflex action. An example of a reflex arc is when we accidentally touch a hot object. First, the receptor in the skin detects a stimulus in this case the change in temperature. Second, the sensory neuron transmit the electrical impulses to the Central Nervous System for information processing. Then relay neurons connect sensory neurons to motor neurons. Third, motor neurons sends electrical impulses to an effector wherein the effector produces a response ( muscle contracts to move the hand away from the hot object. This happens in a split of seconds.
