Answer: The probability of having an offspring that is dwarf in size is zero.
Explanation: Since tall phenotype is dominant to dwarf phenotype, let T represent allele for tall and t represent allele for dwarf. A heterozygous pea plant will have Tt genotype while a homozygous tall pea plant will have a TT genotype. A cross between them will produce two homozygous tall pea plants (TT) and two heterozygous tall pea plant (Tt). They will not have any offspring having a dwarf size. Therefore, the probability of having a dwarf offspring is zero.

Answer:
The major structural difference between chromatin and chromosomes is that the latter are more organized and condensed.
Explanation:
Chromatin is genetic material packaged into a complex by special proteins (histones). That complex is in the form of uncoiled structures, so chromatin fibers are long and thin. Chromatin structure is permissive to DNA replication, transcription and recombination events.
On the other hand, chromosomes are highly condensed structures of genetic material that are formed just before the cell division.
Metal contain free electrons which makes it easier to transfer energy through the solid (conduction). Non-metals are poor conductors (insulators) because they do not contain free electrons.

Answer:
The predation pressure increases mate
Explanation:
Since the observation of the scientist goes in order to increase the coloration in males, because of the predation pressure, and as a consequence the females are attracted by this colored mates.
It will be expected that the increase in pressure, it will increase the colored in skin, and this could end in an increase of the number of mates per male.
Answer:
The correct answer would be D. absorption and radiation of energy in the atmosphere.
Green house effect refers to the process by which heat or radiation from the sun as well as those radiated from the surface of the earth are trapped in the atmosphere.
It gradually results in increase of the temperature of the earth.
Due to increase in greenhouse gases such as carbon dioxide, methane et cetera the average temperature of the earth keeps on increasing and thus results in global warming.
