The correct answer should be A. spores
Ferns don't have seeds and they reproduce using spores. Cones have seeds in them and seeds fall out. Pollen enters a flower and then the flower becomes a fruit. This is sexual reproduction of plants. Since ferns don't have this, they have to reproduce with spores.
Must be talc because it is one of the softest minerals
Answer:
Volume= 4 cm³
Density= 2 g/cm³
Explanation:
We have the following data:
volume= V= 8 cm³
mass= m= 16 g
The density is the mass per volume of a substance, so the density of the rock is:
density= d= 16 g/8 cm³= 2 g/cm³
When we cut the rock in half, we have a half volume and a half mass:
V= 8 cm³/2= 4 cm³
m= 16 g/2= 8 g
But the density is not altered because it is an intrisic property - it does not change with the amount of subtance. Thus, the density of a half rock is:
d = m/V= 8 g/4 cm³= 2 g/cm³
Given what we know, we can confirm that the biome is in fact an open system due to the interactions between the biosphere, atmosphere, lithosphere, and hydrosphere.
<h3>What is the biome?</h3>
- The biome is the collection of air, soil, water, and all the organisms that reside within these ecosystems.
- In order to describe an open system, we say that the system must have external interactions.
- A biome is an open system because it has both internal and external interactions, such as with asteroids in space.
- The internal interactions include the ones between the<em><u> biosphere, atmosphere, lithosphere, and hydrosphere.</u></em>
- A prime example is the movement of water through each of the spheres.
Therefore, since each part of the biome interacts with each other as well as with external sources such as space, we can confirm that it complies with the definition of an open system.

I can’t see the image but I would guess animals such as deer or horse or elephants or any large animal have the ability to run over the rocks and turn them to smaller sediments
