The "photoelectrons" emitted as a result of the photoelectric effect have a certain kinetic energy, which can be measured. This kinetic energy (for each photoelectron) is independent of the intensity of the light, but depends linearly on the frequency; and if the frequency is too low (corresponding to a photon energy that is less than the work function of the material), no photoelectrons are emitted at all, unless a plurality of photons, whose energetic sum is greater than the energy of the photoelectrons, acts virtually simultaneously (multiphoton effect) Assuming the frequency is high enough to cause the photoelectric effect, a rise in intensity of the light source causes more photoelectrons to be emitted with the same kinetic energy, rather than the same number of photoelectrons to be emitted with higher kinetic energy.
If the photoelectric effect is occuring, increasing the intensity of the light source causes what?
more photoelectrons to be emitted with the same kinetic energy

Plants synthesize a number of unique polymers like the polysaccharide molecules cellulose, pectin and xyloglucan from which the land plant cell wall is constructed. Vascular land plants make lignin, a polymer used to strengthen the secondary cell walls of xylem tracheids and vessels to keep them from collapsing when a plant sucks water through them under water stress. Lignin is also used in other cell types like sclerenchyma fibers that provide structural support for a plant and is a major constituent of wood. Sporopollenin is a chemically resistant polymer found in the outer cell walls of spores and pollen of land plants responsible for the survival of early land plant spores and the pollen of seed plants in the fossil record. It is widely regarded as a marker for the start of land plant evolution during the Ordovician period. The concentration of carbon dioxide in the atmosphere today is much lower than it was when plants emerged onto land during the Ordovician and Silurian periods. Many monocots like maize and the pineapple and some dicots like the Asteraceae have since independently evolved pathways like Crassulacean acid metabolism and the C4 carbon fixation pathway for photosynthesis which avoid the losses resulting from photorespiration in the more common C3 carbon fixation pathway. These biochemical strategies are unique to land plants.
What gas is in lower concentration now due to plants?
carbon dioxide

In the 1874 general election, Disraeli was returned to power. He passed the Public Worship Regulation Act 1874, which removed Catholic rituals from the Anglican liturgy and which Victoria strongly supported. She preferred short, simple services, and personally considered herself more aligned with the presbyterian Church of Scotland than the episcopal Church of England. He also pushed the Royal Titles Act 1876 through Parliament, so that Victoria took the title "Empress of India" from 1 May 1876. The new title was proclaimed at the Delhi Durbar of 1 January 1877.
What allowed Victoria to become the Empress of India?
Royal Titles Act 1876
