Answer:
21 chromosomes
Explanation:
Meiosis is a type of cell division that produces 4 haploid daughter cells (i.e., gametes) from a single diploid cell. This parental cell undergo one (1) cycle of DNA replication and two (2) cell divisions, thereby, in the case of the Norway rats that have 42 chromosomes, the final number will be 21 (21 x 2= 42)
Diffusion is the movement of particles from a high concentration area to a low concentration area.
Things that can go through a membrane are ions (charged), small polar molecules. Big molecules can't go through the membrane due to its large size and disrupting the membrane.
Passive transport is the movement of substances acrpss the cell membrane w/o the use of energy. Active transport needs energy to move substances across a cell membrane.
Couples who cohabit are characterized by a lower level of commitment when
compared to married couples. Cohabiting couples are two people who live
together but are not married. The form of relationship between the two people
is a loose relationship because it does not have a legal binding and they are
free to separate at any time.
Explanation:
Distance = 826m
time = 70second
velocity = distance/ time
v = 826/70
v = 11.8m/sec
