Humans - caused environmental changes lead to the natural selection among the pepper moths in Manchester England.
The evolution of the peppered moth is a metamorphic occasion of a directional color change in the moth population as an aftereffect of air pollution during the Industrial Revolution.
Answer:
B. He has no E alleles.
Explanation:
In order for the boy to have an attached earlobes phenotype, he must have no E alleles, because the E is dominant. So his genotype must be ee. If he has even just a single E allele (like Ee) he will have detached earlobes, because the dominant trait will mask the expression of the recessive trait.
Why not A or D: Heterozygous Ee (one of each allele) would result in detached earlobes.
Why not C: If he has no recessive alleles, EE, he would have detached earlobes.
Reducing sugar is any sugar (all monosaccharides, some disaccharides, oligosaccharides, and polysaccharides) that is capable of acting as a reducing agent because it contains free aldehyde group or free ketone group.
Aldehyde group or alkanal is an organic compound containing formyl group. The formyl group is a functional group consisting of a carbonyl center bonded to hydrogen and an R group. This group can be readily reduced to primary alcohol with the help of catalyctic hydrogenation either applied directly or by transfer hydrogenation.
Ketone group unlike aldehyde group does not have a hydrogen atome bonded to the carbonyl group but it can still be hydrogenated.
Answer:
yes
Explanation: The atoms and molecules that make up a gas are constantly moving. Temperature is a measure of the speed with which they move (more accurately it is a measure of their kinetic energy). The higher the temperature, the faster they move. It is thus produced a greater intensity in the collisions against the walls: the pressure of the container containing the gas increases.In this way, if the graph shows the increase in temperature as well as the increase in speed, yes, it is correct.
