Not every plant grows from a seed. Some plants, like ferns and mosses, grow from spores. Other plants use asexual vegetative reproduction and grow new plants from rhizomes or tubers. We can also use techniques like grafting or take cuttings to make new plants.
gas to liquid
Explanation:
The change of state indicated by this analogy is from gas to liquid.
Cylinder to the left is filled with gases
Cylinder to the right is made up of liquid.
- Gases occupy the volumes of containers they are introduced into.
- They are random and possess a high kinetic energy.
- Liquids have definite volume and flow with one another.
- The gases in A are dispersed and in random motion.
- This phase change is called condensation

Answer:
D
Explanation:
Because I carbon atom and 1 hydrogen atom plus 2
Oxygen atoms are needed
Heat energy is supplied to materials and can cause an increase in temperature of the material. the formula is as follows
H = mcΔt
where H - heat energy
m - mass of material
c - specific heat
Δt - change in temperature - 40.0 °C - 22.5 °C = 17.5 °C
substituting the values
H = 175 g x 0.234 Jg⁻¹°C⁻¹ x 17.5 °C
H = 716.6 J
716.6 J is required
