Step 1: Understanding spore dispersal in Funaria.
Funaria, commonly known as moss, utilizes peristomial teeth located around the mouth of the spore capsule. These teeth are hygroscopic, meaning they respond to moisture changes. When it's dry, they bend outward to release spores, and when it's moist, they close to protect the spores inside.
Step 2: Mechanism functionality.
The mechanism allows Funaria to efficiently disperse its spores during favorable conditions, ensuring better germination and survival rates in suitable environments.
The percentage error in the measurement of mass and velocity are 3% and 4% respectively. The percentage error in the measurement of kinetic energy is:
If \( L, M, N \) are the midpoints of the sides PQ, QR, and RP of triangle \( \Delta PQR \), then \( \overline{QM} + \overline{LN} + \overline{ML} + \overline{RN} - \overline{MN} - \overline{QL} = \):
