It implies that There are 46 chromosomes (dsDNA (double-stranded) molecules) are present in each somatic cell.
Homo sapiens has 46 chromosomes divided into 23 pairs: 22 pairs of autosomes and 1 pair of gonosomes or sex chromosomes, called X and Y. Male individuals have X and Y (XY) chromosomes. Female individuals have 2 X (XX) chromosomes.
Aneuploidy is an abnormal change in the number of chromosomes in a cell or organism (for example 45 or 47 chromosomes).
In addition to the chromosomes in the nucleus, human cells have DNA in the mitochondria (circular DNA).

It seems that you have missed the necessary options for us to answer this question, so I had to look for it. Anyway, here are the answers. The six statements that reflect angiosperm adaptations to life on land are the following:
*Fruits aid in the dispersal of seeds by wind or by animals that carry or eat the fruits.
*Seeds protect and nourish plant embryos, and fruits protect the seeds.
*Seeds enable plant embryos to be dispersed long distances from the parent plant via wind or animals.
*In many angiosperms, the male gametophyte contained in a pollen grain can be transported many miles away by wind or animal pollinators.
*Flowers attract animal pollinators carrying pollen from other plants of the same species.
*Floral parts of the sporophyte protect the reduced female gametophyte from drying out and <span>from UV radiation.</span>
When a gene mutation occurs, the nucleotides are in the wrong order which means the coded instructions are wrong and faulty proteins are made or control switches are changed. The body can't function as it should. Mutations can be inherited from one or both parents. They are present in the egg and/ or sperm cells.
