Answer:
a. 100% of the offspring will have the Bb genotype
Explanation:
In a BB x bb cross, the one with BB genotype produces B gamete, while the other only produces b gamete.
Therefore, the zygote in this cross has Bb genotype.
The sequence that represents the proper order of increasing bond strength is A. single bond >double bond>triple bond. Single bond is normally present in saturated compounds such as alkanes, while double bands and triple bonds are present in unsaturated compounds such as alkenes and alkynes.
Let's go back to "Darwin's" evolution theory. mice can be smarter than the average hawk, they are fast, have underground protection from cold,heat, rain,ECT..and they scavenge during p.m. hours, not all hawks are nocturnal, that's why owls are nocturnal. This cycle ensures enough food source for all predators. A hawk can consume at least 6 mice per day/night. rodents are natural prey for all preditors., even coyote. hope this helps, plus mice reproduce quickly compared to preditors.
hope this helps..
Answer:
If the cancer cell's DNA is sequenced than the anticipated results will be that the cytosines in or close to the promoter region will get methylated. It has been stated that in the cancer cells one allele of p53 is mutated and the other allele, however, of exhibiting an intact promoter, does not express the protein.
Thus, it shows that the expression in the other allele gets suppressed by methylation rather than by mutation. Methylation generally takes place in CpG islands in or close to the promoter region and therefore inhibits transcription.
Mammals survived the K-Pg mass extinction event because they are able to regulate their body temperature in the face of reduced sunlight and colder temperatures.
<h3>What is the K-Pg mass extinction event?</h3>
The K-Pg mass extinction event is a sudden extinction of mammals that happened over 66 million years ago on earth and affected several species.
One of the factors that enabled the mammals to survive this K-Pg mass extinction event is that mammals are able to regulate their body temperature in the face of reduced sunlight and colder temperatures.
