If a somatic human cell is about to divide, then it has 92 chromatids. this is because there are 23 pairs of homologues chromosomes in a cell, one is given by both parents. when a cell divides my mitosis, the pairs separate into 46 chromatids, each one that is replicated which gives you 92 chromatids.

Answer:
1,2
Explanation:
During mitosis, a eukaryotic cell undergoes a carefully coordinated nuclear division that results in the formation of two genetically identical daughter cells. ... Then, at a critical point during interphase (called the S phase), the cell duplicates its chromosomes and ensures its systems are ready for cell division.
 
        
             
        
        
        
Answer:
Adjust your day-to-day behaviors
Energy conservation can be as simple as turning off lights or appliances when you do not need them. You can also use energy-intensive appliances less by performing household tasks manually, such as hang-drying your clothes instead of putting them in the dryer, or washing dishes by hand.
