Answer:
A. 17,100
Explanation:
The half life of carbon-14 is around 5,700 years. When the shell contains 50% of its original carbon-14, 5,700 years have passed. 25% means another 5,700 years have passed, meaning 11,400 years in total have passed. 12.5% means another 5,700 years have passed, meaning 17,100 years have passed in total.
Answer:
1. Segregation, one, 50%.
2. Punnett Square, A Punnett square allows the prediction of the percentages of phenotypes in the offspring of a cross from known genotypes (shows the probability of an offspring with a given genotype resulting from a cross), It does not show actual offspring.
Explanation:
Punnett Square, this gives you the total number of predicted offspring.

An example of vesiscle-mediated transport would be cell secretion by exocytosis.
The reason why this would be an example of vesicle-mediated transport is because all the other types of transport listed here are not something you would call vesicle-transport; the substances don't really get transported in vesicles. This is different in exocytosis where the compounds gets packaged into vesicles.
