Answer:
The statement is False
Explanation:
Radiation is the emission of energy as electromagnetic waves or especially high-energy particles which cause ionization. It is not necessary that the source of heat must be a liquid. Most of the time radiation is produced from a solid substance which burns with a high amount of temperature. That temperature is transferred to the surroundings in the form of electromagnetic waves and they do not require any medium to propagate.
The correct answer for above statement is:
They ravel faster than s waves.
Explanation:
A P-wave is one of the couple main types of flexible body waves, called seismic waves in seismology. P-waves move faster than other seismic waves and therefore are the first signal from a shock to arrive at any changed location or at a seismograph. P-waves may be conveyed through gases, liquids, or solids.
these are Congressional waves.They are longitudinal waves the particle swing parallel to the administration where the wave is progressing.They can travel within solids, liquids, and gas
Answer:
Angiosperms have seeds with an 3n endosperm due to double fertilization.
Explanation:
- Double fertilization is found only in flowering plants.
- In angiosperms, the female gametophyte does not grow after reaching eight nucleate stage.
- After fertilization and triple fusion, the zygote and primary endosperm are created and further growth of embryo sac continues.
- Triple fusion is the fusion of two haploid polar nuclei of female gametophyte and one male nuclei. This results in a 3n nucleus.
- The developing embryo obtains nutrition from the endosperm.
- If fertilization fails no endosperm is formed.
