Answer:
The male creeper and the female creeper are both heterozygous for the creeping trait.
Explanation:
The creeping allele Cr is dominant. For any chicken to have the wild-type long leg attribute, the dominant allele must be absent in its genotype. This means that such an individual would have two recessive alleles, each from either parent.
Hence, in order for two parents to produce wild-type offspring at all, both of them would have to be heterozygous for the creeping trait.
Assuming that the alternate trait is represented by cr allele:
Crcr x Crcr
CrCr Crcr Crcr crcr
<em>The two parents in the above cross are creepers but were able to produce wild-type offspring as a result of both parents being </em><em>heterozygous. </em>
The characteristics of the nutria include of those here EXCEPT that "nutria can only live in freshwater marshes in coastal areas along the Gulf Coast".
<u>Option: D</u>
<u>Explanation:</u>
Nutria survives not only in freshwater marshes but also in wetlands, and can respond to various environments reasonably easily. In aquatic habitats, the species flourish and migrate rapidly across rivers into coastal wetlands. Nutria harm prone ecosystems can be seen in many ways.
Beyond destroying plants and crops, nutria kills the channels of ditches, streams, and other water bodies. Even so, the irreversible harm that nutria can do to marshes and other wetlands is of utmost importance. Nutria in these places rely on native plants which hold together wetland soil. This vegetation's degradation exacerbated the depletion of coastal marshes caused by sea level rise.

Answer:
Life on Earth began in the water. So when the first animals moved onto land, they had to trade their fins for limbs, and their gills for lungs, the better to adapt to their new terrestrial environment. ... In air, eyes can see much farther than they can under water.Explanation:
Answer:
Eukaryotes have multiple replication forks, histones. Eukaryote have more Deoxyribonucleic acids in their genome compared to prokaryotic cells (e.g bacteria)
Explanation:
Bacteria is an example of prokaryotic cell. The difference between Eukaryotic cells and Prokaryotic cells is that prokaryotic cells are simple in structure, they have no nucleus, no organelles and a small amount of DNA in the form of a single, circular chromosome. While Eukaryotic cells have a well defined nucleus, multiple organelles and more DNA arranged in multiple, linear chromosomes
DNA synthesis is therefore more complex in eukaryotes because eukaryotes have multiple replication forks in which when replication occurs, precautions need to be set in place in order to prevent unwinding of the DNA strand in multiple sites in a single replication cycle. Also, the DNA in eukaryotes is packaged around histones to form chromatin. Before replication can occur, DNA needs to first be unwound around histones.
Eukaryotic DNA polymerase incoperates DNA at a much slower rate (17 nucleotides per second) than prokaryotic polymerase (1000 nucleotides per second). Therefore the eukaryotic cells are equipped with a slower polymerase but numerous replication forks more than just the two that are found in prokaryotic cells in order to effectively replicate the increased amount of DNA.
