Ionic bonding is the complete transfer of valence electron(s) between atoms. It is a type of chemical bond that generates two oppositely charged ions. In ionic bonds, the metal loses electrons to become a positively charged cation, whereas the nonmetal accepts those electrons to become a negatively charge
Answer:
When an organism is buried quickly, there is less decay and the better the chance for it to be preserved. The hard parts of organisms, such as bones, shells, and teeth have a better chance of becoming fossils than do softer parts. One reason for this is that scavengers generally do not eat these parts.
Explanation:
It is an indicator of poor air quality from air pollution. This pollution is most often ozone or particulates. Typically it indicates that the air is unhealthy for children, the elderly, and sensitive groups.
The answer is <span>yellow and dominant.
We have two alleles, one dominant and one recessive: Y and y. Usually, a capital letter is used for dominant alleles, so Y is a dominant allele and y is a recessive allele. There are three combinations of those alleles, and thus, three genotypes: YY, Yy, yy.
We know that </span><span>Yy is for yellow seeds. An individual with Yy is heterozygote. Heterozygotes have one dominant and one recessive allele, but the dominant masks the recessive allele, so expressed trait is dominant. Since yellow seed is the result of heterozygous Yy, yellow seed is the dominant trait.
Therefore, Y means yellow and dominant.</span>
