Answer: It shows that the object is supposedly moving toward the observer
Explanation: A spectrum typically displays intensity and wavelength which characterises light.
The condensed formula would be CH3-CH(CH4)-CH2-CH(CH4)-CH2-CH(CH4)-CH3. The molecular formula would be C10H25.
Answer:
NA + F2 = NAF - Chemical Equation Balancer.
2 Na + F 2 → 2 NaF
Na is a reducing agent, F 2 is an oxidizing agent. ; Pale-yellow to greenish gas with a pungent, irritating odor.
Vacuoles
➡️Plants have single large vacoule as compared to the animals which have many small vacuoles.✔️
➡️The main reason behind this fact are as follows:✔️
Storage:
➡️Plants form the base of the food chain.✔️
➡️They are capable of converting inorganic matter to organic matter.✔️
➡️To store these inorganic ions they are provided with the large vacuoles.✔️
➡️Moreover, plants can not move from one place to another.✔️
➡️So, it is very
easy for a plant to be able to store extra nutrients when they are around for use later when nutrients may not be available✔️
Growth:
➡️Plant cells grow by swelling.✔️
➡️They are provided with a rigid cell wall.✔️
➡️To make this wall expand, plant cells fill their vacuoles to exert pressure from inside.✔️
B)Argon and Krypton is applied for that..........
