castortr0y [4]

Answer:

The correct answer is ''They are all vascular plants''.

Explanation:

Vascular plants or tracheophytes are those organisms of a more evolved plant nature, they are those that have leaves, stem and roots and that have a vascular system formed by conducting vessels. Ferns are pteridophytic vascular plants, they do not produce flowers or seeds and are mostly herbaceous. All those vascular plants that have seeds but do not have flowers are called gymnosperms. The seeds are not covered or protected by an ovary, so they appear visible on the leaves or other parts of the plant. Angiosperms are plants with flowers, whose seeds develop within the ovary, which grows and becomes fruit.

An aquarium has a volume of 2.75 cubic meters. How many liters of water can the aquarium hold?
Slav-nsk [51]

Answer:

2,750 liters of water

Explanation:

A cubic meter or 1 m³ is equivalent to 1,000 liters. Knowing this you can covert 2.75 m³ to liters.

2.75 m^{3} \times \dfrac{1,000L}{1m^{3}}= 2.75 \times 1,000L = 2,750 L

Just remember if you're using this method that always put the value with the unit that you want to convert as the denominator so you can cancel them out.
