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.
Our bodies sweat to cool us off and to avoid overheating. Therefore, I think the answer would be "liquid (sweat) sitting on the skin's surface" because sweat has been produced and is sitting to cool the skin. The other options seem to be either after the sweating occurs or interrupts the process of cooling. The third option is my best, process-of-elimination guess. Hope this helps.
B. Anions have more electrons than protons, giving them a negative charge.
D. Cations have more protons than electrons, giving them a positive charge.
Explanation - Ions are the result of atoms or molecules that lose or gain electrons. If an atom or a molecule is positively charged then it is called as cation and if it has negative charge then it is called as anion.
Cations have positive charge because the atom has lost its electron while anions have negative charge because the atom has gained the electron. The number of protons is more than the electron in cations and less in anions.
