Ground tissue makes up most of the interior of a plant. It carries out basic metabolic functions and stores food and water. Vascular tissue runs through the ground tissue inside a plant. It consists of bundles of xylem and phloem, which transport fluids throughout the plant. Choices: - dorsal - mucous - anterior - dermal A:
**Answer**
dermal

Q: How many valence electrons do neutral phosphorus atoms have? Read this paragraph and choose the correct option from the provided answers: The highest-numbered shell is the third shell, which has 2 electrons in the 3s subshell and 3 electrons in the 3p subshell. That gives a total of 5 electrons, so neutral phosphorus atoms have 5 valence electrons. The 10 remaining electrons, from the first and second shells, are core electrons. Choices: - nine - three - four - five A:
**Answer**
five
