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.
Answer:
Chlorophyll is a green pigment which is present inside the chloroplast. Chlorophyll is responsible for the conversion of sun energy into chemical energy in the process of photosynthesis. Photosynthesis is a process in which energy is produced by the combination of carbondioxide and water in the presence of sunlight produces glucose and oxygen. This sunlight is absorbed by chlorophyll which is present in the leaves.
<span>Antibiotic resistance arises due to the evolution of the organisms they are designed to destroy. Subsequent generations of such organisms develop resistance to the antibiotic. Hospitals' overuse of antibiotics quickens the process, as does the administration of antibiotics to feedlot cattle, whose meat is consumed by people.</span>
Answer:mutualism
Explanation:
In a mutualistic relation,both organisms involved benefit from the activities of each other. The benefits may be nourishment,shelter, protection etc.
In the above example,the birds are known to guide humans by responding to specific calls made by the human. They guide humans to beehives and then in return gets to feed on left over honey. Both the bird and human benefits by getting nourishment.
Mutualism is unlike parasitism where one of the organism involved benefits and the other organisms Is most likely harmed. It is also not commensalism, where one organism benefits and the other neither benefits nor is harmed
