Answer: Organism in this domain can be defined as living things that has an organized structure, and responds to stimuli, and has ability to reproduce, grow, and maintain a state of equilibrium. Organisms are of two types which are unicellular and multi cellular organisms.
Explanation: unicellular organisms are organisms that are made up of only one cell which carries out all the functions needed by the oragnism. Multicellular organisms are organisms that are made up of more than one cell. These organisms uses many different cells to function.
Unicellular organisms are often found in extreme environments such as hot springs, polar ice and frozen tundra.
Unicellular organisms have cell that contain a nucleus.
4) b removing more co2 from the atmosphere
5) a more sea ice melting
6) tolerate c
7) stained teeth b
8) polar bear will consume less seal meat
9) past and more current research (not sure)
Answer: The correct answer is D) The number of chromosomes remains the same in mitosis and is reduced by half in meiosis.
Explanation-
Mitosis and meiosis are the two forms of cell division. Mitosis occurs in all the living organisms. In mitosis, cell divides into two daughter, each having equal number of chromosomes with that of the parental cell. It is also a process of asexual reproduction.
Whereas, meiosis typically occurs in sexually reproducing organisms during gamete formation. In this process, the number of chromosomes are reduced to half as the homologous chromosomes are separated.
Thus, the number of chromosomes remains the same in mitosis and it is reduced by half in meiosis.
