Answer:
The correct answers would be maintain chromosome number through generations  and cause genetic variations by recombination.
In Meiosis a cell divides into four daughter cells all of which have half the number of chromosomes present in a parent cell.
It helps in the formation of gametes in sexually reproducing organisms.
These gametes (one from father and one from mother) fuse together to form a zygote. It re-established the chromosomal number as that of the parent.
In absence of meiosis, the chromosomal number would have doubled after each generation.
In addition, the meiosis also increases the genetic variation among the population with the help of crossing over which occurs during the pachytene stage of prophase I.
During this event, genetic information is exchanged between the non-sister chromatids of the homologous chromosomes. It produces a new combinations of genes that are different from either parent.
 
        
                    
             
        
        
        
One of the major functions of erythrocytes (also known as red blood cells) is to carry blood gases such as oxygen and carbon dioxide around the body. Red blood cells contain the pigment haemoglobin which binds to oxygen and carries it around the body, releasing it and allowing the process of aerobic respiration. 
        
             
        
        
        
Answer: The correct answer is peripheral 
Explanation:
The Peripheral nervous system consists of the following:
- sensory neurons, which leads all parts of the body to the central nervous system 
- motor neurons that runs the central nervous system to all parts of the body.
Thus, Peripheral nervous system is the answer
