Answer the following question given this paragraph: A later adaption for life on land was the evolution of vascular tissue. Vascular tissue is specialized tissue that transports water, nutrients, and food in plants. In algae, vascular tissue is not necessary since the entire body is in contact with the water, and the water simply enters the algae. But on land, water may only be found deep in the ground. Vascular tissues take water and nutrients from the ground up into the plant, while also taking food down from the leaves into the rest of the plant. The two vascular tissues are xylem and phloem. Xylem is responsible for the transport of water and nutrients from the roots to the rest of the plant. Phloem carries the sugars made in the leaves to the parts of the plant where they are needed. Q: What type of tissue transports water, nutrients, and food in plants? Choices: - rough tissue - normal tissue - smooth tissue - vascular tissue A:
**Answer**
vascular tissue

Answer the following question given this paragraph: Rutherford's atomic model became known as the nuclear model . In the nuclear atom, the protons and neutrons, which comprise nearly all of the mass of the atom, are located in the nucleus at the center of the atom. The electrons are distributed around the nucleus and occupy most of the volume of the atom. It is worth emphasizing just how small the nucleus is compared to the rest of the atom. If we could blow up an atom to be the size of a large professional football stadium, the nucleus would be about the size of a marble. Q: In an atom, what two major types of particles are located in the nucleus? Choices: - electrons and neutrons - molecules and neutrons - ions and electrons - protons and neutrons A:
**Answer**
protons and neutrons
