Answer the following question given this paragraph: Figure 26.8 illustrates the life cycle of a conifer. The sporophyte (2n) phase is the longest phase in the life of a gymnosperm. The gametophytes (1n)microspores and megasporesare reduced in size. It may take more than year between pollination and fertilization while the pollen tube grows towards the megasporocyte (2n), which undergoes meiosis into megaspores. The megaspores will mature into eggs (1n). Q: The sporophyte phase is the longest phase in the life of what? Choices: - echinoderm - arthropod - angiosperm - gymnosperm A:
gymnosperm

Question: Answer the following question given this paragraph: Pollination by Insects Bees are perhaps the most important pollinator of many garden plants and most commercial fruit trees (Figure 32.12). The most common species of bees are bumblebees and honeybees. Since bees cannot see the color red, bee-pollinated flowers usually have shades of blue, yellow, or other colors. Bees collect energy-rich pollen or nectar for their survival and energy. Q: What important function do bees perform on garden plants and many commercial fruit trees? Choices: - hibernation - ruination - condensation - pollination A:
Answer: pollination

Answer the following question given this paragraph: Consider the example of water forming from hydrogen and oxygen. Both hydrogen and oxygen gases exist as diatomic ("two-atom") molecules. These molecules are the reactants in the reaction. The Figure below shows that bonds must break to separate the atoms in the hydrogen and oxygen molecules. Then new bonds must form between hydrogen and oxygen atoms to form water molecules. The water molecules are the products of the reaction. Q: What is the name for a molecule with two atoms? Choices: - hydrostatic - ionized - covalent - diatomic A:
**Answer**
diatomic
