A.it is a gas at room temperature
B. it reacts to iron to form rust
C.it expands when heated
Dit combines to form O2 molecules
It is multicellular.
B.
It does not have a nucleus.
C.
It possesses a membrane-bound nucleus.
D.
It possesses a hard outer shell.
The smallest living organisms which are capable of survive independently in nature are those which possesses a membrane-bound nucleus. Thus, the correct option is C.
A cell is the fundamental unit of life. It is the structural and functional unit of all living organisms. Cells are classified on the basis of its structure, function and origin.
Cells contain a nucleus which contains all the genetic material of an organism The genetic material is stored in the form of nucleic acids such as DNA or RNA. A membrane-bound nucleus is present in all eukaryotic organisms. This membrane helps to separate the nuclear material from the cytoplasm.
The presence of a nucleus is important for all the living organisms as this nucleus contains genetic information which is transferred to the offsprings and hence responsible for reproduction and maintaining the number of organisms.
Therefore, the correct option is C.

Cool ocean air can cause a cooler climate.
Explanation: An ocean is a very important abiotic factor in any environment and has impacts on the climate of the environments it is found. The ocean currents are driven by the global wind system, which is powered by the energy of the sun. These currents transfer heat to the polar regions from the tropics and brings about the sooling of their environment, thus giving rise to cool climate.
Answer:
2 (if you are just talking about Mitosis)
Explanation:
In Mitosis (the reproduction of body cells) there are two diploid (and identical) daughter cells
In Meiosis (the reproduction of gametes) there are four haploid (but non-identical) gametes (or reproductive cells)
I am pretty sure that you are talking about Mitosis but I wanted to add in Meiosis just for kicks.
