Adult males show more lateralization than adult females.
The jugular veins are the veins responsible for bringing deoxygenated blood from the head to the heart. There are two sets of jugular veins, the internal and external ones. In pigs, the internal and external jugular veins are similar in size, while in humans the internal jugular vein is bigger in diameter than the external.
Answer:
The order of development has been large brains, bipedalism, tool use, modern behavior.
Explanation:
A is not correct because the human ancestors had large brains before they become bipedal, which is not weird considering the fact that all primates have proprtionately large brains, even for mammals.
B is correct because the large brains were already a trait of the human ancestors, with the change of environment they developed bipedalism, with the further growth of the brain and anatomic changes in the fingers the humans developed tools, and last but not least came to modern behavior.
C is not correct because bipedalism occurred before the usage of tools.
D is not correct because the tool usage did not occur at the beginning of human evolution, but several million years later.
E is not correct because the bipedalism occurred later than the large brains, and the modern behavior came the last, not in the early stages.
True I think it is to beacuse I did the work
Okay, first the clear up. The Homozygous dominate trait is RR and is Red, the Heterozygous trait is Rr and is Pink, and the Homozygous recessive trait is rr and is white.
Part A: The co-dominance or incomplete dominance mixes the colours together, so the phenotype for the Heterozygous Rr flower is pink.
Part B: This question is easiest to explain with a punnet square... so. Diagram attached.
Part C: To get only Heterozygous genotypes, the gardener must cross only White flowers with red flowers. Because both these flowers are homozygous pairs, it means that any offspring created from that group would have a mix of the two. This is clearly seen in the F1 generation of Mendel's experiments for further proof. If any other pair is chosen ie Red with red: all red offspring, white and white, all white offspring. Pink and pink, a 1:2:! ratio. Red and Pink: 1:1 ratio of red and pink. White and pink: 1:1 ratio of pink and white. Red and white: Only pink offspring.
Hope that helps, message if you need it explained.
