Answer: 23
Explanation: One pair of the 23 chromosomes, known as sex chromosomes, determines at conception whether a fertilized egg will develop into a male or female. Today, human females have one pair of identical X chromosomes.
The pH scale is a logarithmic one, meaning that each pH unit has 10 times as many hydrogen ions as the unit above it. So, at pH 4, there are 10 times more hydrogen ions than at pH 5 and 100 times more hydrogen ions than at pH 6.
Inhale and exhale because you inhale the oxygen and exhale the carbon dioxide
Answer:
Northern
Explanation:
The northern hemisphere is not in the sunlight, therefore it is winter.
Answer:
The results indicate that two independently assorting genes are involved (modified 9:3:3:1 ratio), with white blocking the expression of color by the other gene. The ratio of white : color pups is 3:1, indicating that the F.1 is heterogeneous (W/w). Among colored dogs, the ratio is 3 black : 1 brown, indicating that black is dominant to brown, and the F.1 is heterogeneous (B/b). The original brown dog is w/w ; b/b, and the original white dog is W/W ; B/B. The F.1 progeny are W/w ; B/b, and the F.2 progeny are: 12: 3: 1.
