The best answer is D.
A carbon sink is anything that absorbs more carbon than it produces or releases.
The main carbon sinks found in nature are plants, the ocean and soil. Plants such as trees capture carbon dioxide from the atmosphere and use it in photosynthesis. Part of this carbon is transferred to soil as the trees and other plants die and decompose.
Due to the effectiveness of trees and other plants as carbon sinks, the Kyoto protocol proposed that emission reduction can be achieved through absorption of carbon dioxide by these plants.
The answer should be B Convection
Answer:
A- Different species
Explanation:
Dogs and Cats are distinct species incapable of producing offspring because of the many differences in their genome.
Answer:
In humans the genetic commonality of height and skin tone is that they are both <u>Polygenic Traits.</u>
Explanation:
Polygenic traits can be described as those characteristics for which there is more than one gene to determine its inheritance. The outcomes of polygenic genes result in many differentiated phenotypes. For example, the difference in height, the difference in skin colour etc.
Polygenic traits occur because one allele for a gene does not have complete dominance over the other gene. This is termed as incomplete dominance. Incomplete dominance is a Non- Mendelian trait as Mendelian traits showed one allele to be completely dominant over the other allele.
Since it's incomplete dominance we know that all the traits are of course dominant.
That in mind we know that anything heterozygous will have two different traits, making the cream colored mice have a punnet square somewhat like this:
W Y
W WW WY
Y WY YY
Referring back to the yellow and white mice being homozygous (two of the same traits) we can gather from this punnet square the ratios for both.
WC = Cream colored = 50%
WW = White = 25%
YY = Yellow = 25%
