I dont know what the options are. just send the options and i can answer
Answer:
1) the genes and chromosomes do not double after each generations because parental sex cells are haploid and only contain one set of chromosomes. During fertilization the two cells fuse to form a diploid zygote with two copies of genes and chromosomes. For example a normal human has 46 chromosomes (2 copies of 23 chromosomes) during reproduction gametes which contain 23 chromosomes (haploid) fuse to form an offspring with the correct number of chromosomes ( 23 + 23 = 46).
2) offspring only receive one set of chromosomes from each parent so to maintain the chromosome number of humans. If this did not happen you would not be the same species.
The properties of water that contribute To The formation of the meniscus are:
Meniscus is defined as the upward or downward curve located at the surface of a liquid in a tube.
When water is placed in a tube or wettable container, a concave or downward meniscus is formed due to surface tension created in water through the following properties of water:
- Cohesion: This is the tendency of water molecules to stick to itself.
- Adhesion: This is the tendency of water molecules to stick to other molecules that are charged or polar.
Therefore, the cohesion and adhesion of water molecules contributes to the formation of meniscus.

It's important because we need the scientists to discover where it is. the lokiarchaeota is a main cause for infections, and diseases, and if we identify it, and study it, we may know how to cure certain diseases, and how to prevent them.
Meiosis: cell division into four daughter cells (each has half the number of chromosome of the parent cell)
mitosis: cell division that results in two daughter cells (each has the same number and type of chromosomes as the parent cell)
