Answer:
By observing the size of fontanels.
Explanation:
The archaeologist can determine the age of the skull bones found by observing the fact that whether the large bones of the cranium are fused or not.
The large bones of the skull are joined by connective tissues which is known as fontanels.
The archaeologist can estimate the time it takes for the fontanels to close and this can be determined by observing the size of the fontanels.
Therefore, the observation of the size of the fontanels provides a good estimate of the age of the child which is predicted to be less than 1 year old.
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.
