To answer these questions, let's analyze each option and eliminate the incorrect ones based on the given information.
2. The question asks about the most abundant type of plant that produces something to reproduce. Let's evaluate each option:
- Gymnosperms are plants that produce seeds but not through sperm, so this option is incorrect.
- Nonvascular plants do not produce anything to reproduce, so this option is incorrect.
- Vascular plants do produce seeds, but the question states that the plants are seedless, so this option is incorrect.
The correct option is "seedless vascular; spores."
3. The question asks why mosses never grow very tall. Let's evaluate each option:
- Lack of cell walls is not the cause of mosses not growing tall, so this option is incorrect.
- The presence of cuticles refers to a waxy layer on the surface of leaves to prevent water loss, but it is not the reason mosses do not grow tall, so this option is incorrect.
- More complex reproduction is not the reason mosses do not grow tall, so this option is incorrect.
The correct reason is "lack of vascular tissue." Mosses lack specialized tissues for water and nutrient transport, which limits their ability to grow tall.
4. The question asks about the earliest stage of something that will be produced over time with certain conditions. Let's evaluate each option:
- Coal is not produced with a lot of pressure, so this option is incorrect.
- Natural gas is not produced with moisture, so this option is incorrect.
- Petroleum is not produced with heat, so this option is incorrect.
The correct option is "peat; moisture." Peat is the earliest stage of coal, formed over a long period of time with an abundance of moisture.
