Explanation:
In gases, the forces between particles are very weak. This explains why the particles in gases are not neatly arranged. They are not held together tightly and there are large spaces between them. These spaces are much larger than in the solid and liquid state.

Answer: One chromosome from each pair belongs to the mother and the other to the father

Answer:
All the offspring of a cross between a tall pea plant and a dwarf pea plant are tall. This means that the allele for tall plants is <u>DOMINANT OVER</u> the allele for dwarf plants.
Explanation:
Mendel's law of dominance state that the heterozygous genotype expresses only one allele of a gene out of the two alleles present together. The allele that is expressed in a heterozygous genotype is said to be the dominant one as it does not allow the expression of another allele of the gene. 
The allele of a gene that is not expressed in the presence of its dominant allele is said to be the recessive one. Under such conditions, a heterozygous genotype expresses the dominant phenotype. When a tall and dwarf pea plants are crossed, all the F1 progeny is tall. This means that the allele for the tallness is dominant over the allele for the dwarfism. 
 
        
             
        
        
        
Answer: Reduction of the greenhouse gas carbon dioxide in the atmosphere
Explanation:
phytoplankton use photosynthesis to take the sun’s light waves and convert it into energy. They also take carbon dioxide and convert it into oxygen for other organisms to breathe.
