Farmers have cultivated five different vegetable crops by artificially selecting for certain traits from the wild mustard plant. This table lists
information about five different vegetables that originated from the wild
mustard plant.
Vegetable
Trait
Broccoli Suppression of flower development
Cabbage Suppression of internode length
Kale
Enlargement of leaves
Cauliflower Sterility of flowers
Kohlrabi Enhancement of lateral meristems
Which statement is correct about the development of these vegetables
through artificial selection?
O a
Фь
They resulted from a characteristic of the mustard plant that was changed or enhanced by the selective cultivation.
They resulted from the exposure to extreme temperatures and ultraviolet sun rays.
They were created over one generation when crossbreeding took place between two different varieties of vegetables.
They stopped forming additional varieties at the end of a growth cycle

Scientists are often interested in knowing the molar heat of combustion – the heat released during the combustion of one mole of a substance. use the periodic table to find molar masses. how many moles of ethanol are present in the sample?

For questions 1 and 2, consider the following experimental data.hydrogen emission lines were detected at the following wavelengths (in nm): 121.6102.697.395.093.8question 1use the electromagnetic radiation classifications below and figure 1-1 in the introductory information for this lab (in the lab manual) to determine the nf value for the experimental data provided? wavelength, ?
