Answer:
100% or 1
Explanation:
This question involves a gene coding for fur color in bears. According to the question, black fur allele (B) is dominant over the brown fur allele (b). This means that a bear heterozygous for fur color (Bb) will be phenotypically black.
In this question, a black father bear (genotype BB) and a brown mother bear (genotype bb) were crossed, the baby bears will all have a genotype Bb (see punnet square in the attached image). Since all the offsprings of this cross have genotype Bb, this means that 100% will have black fur.
Natural selection allows nature to chose which species survives. Only the fittest get to pass on their genes. And by fittest i mean the ones that are better adapted to the environment.<span />

Block mountains form along fault blocks. Tension in a fault block can cause horsts in the fault block to tip. The horst edges point upward, forming a range of exposed mountains.
Explanation:
D. Lysogenic cycle. In this cycle, viral DNA is inserted into the host cell's DNA. It divides with mitosis, soon creating many infected host cells. Once the lytic cycle is triggered (usually from external factors), the viral DNA is transcribed/translated into viruses.
Reptiles require external heat to thermoregulate. If a reptile's temperature gets too low, it will need to find a source of heat to raise its body temperature. In the wild, most reptiles do this by basking in the sun. In captivity, heat lights, heating pad, and other heat sources are provided to allow them to thermoregulate.
