Answer:
In horizontal rock layers, the oldest layer is at the bottom. Each higher layer is younger than the layers below it.
Explanation:
Answer:A. Codominance
Explanation:
This is a type of genetic inheritance where neither of the genes is dominant over another. Thus both pair of the gene are expressed on the same LOCUS equally with none masking another. Therefore an individual receive both allele of a heterozygous gene, and have equal phenotypic expression
An example is the AB blood group in man, where both allele present on the same locus are fully expressed with no one dominant over another.
Incomplete dominance refers to a blend of alleles where one does not have full dominance over another another, therefore gives a new phenotypic expression different from both alleles.
e.g pink flower allele in four o'clock flower.
Answer:
Deleterious alleles appear sporadically in a population
Explanation:
A population with a deleterious allele will have no or few individuals that have the ability to pass along these traits. These alleles appear less in a population because of selective pressure but they are not always absent. The alleles appear less often but are are not always passed on and the others that are genetically fit are able to pass along their genes. The reason the population equilibrium is not zero is because these alleles do appear but they are not necessarily passed along. These individuals may not be able to reproduce or reach the age of reproduction.
Deleterious alleles appear more often, making individuals less fit genetically, i.e. they pass fewer copies of their genes to future generations. Put another way, natural selection purges the deleterious alleles.
Answer:
Facilitated diffusion (also known as facilitated transport or passive-mediated transport) is the process of spontaneous passive transport (as opposed to active transport) of molecules or ions across a biological membrane via specific transmembrane integral proteins.

From Wikipedia
Which of the following statements is false? The inflammatory response can occur on the surface of the body and internally. Phagocytes are responsible for much of the healing that occurs with inflammation. Platelets release a growth factor that stimulates endothelial cells to divide, and the wound heals. Pus is produced during an inflammatory response that is inappropriately strong. Mast cells release propagandist, which are partly responsible for the pain of inflammation.
It's B
