Darwin concluded that the finches all shared a common ancestor but had developed different beak structures. The second sentence best describes as an ecosystem.
Explanation:
- When Charles Darwin traveled to the Galapagos Islands, he observed 14 distinct varieties of finches on the islands Darwin also observed that each finch variety ate a different type of food and lived in a slightly different habitat from the other finches, Darwin concluded that the finches all shared a common ancestor but had developed different beak structures. The second sentence best describes as an ecosystem.
- An ecosystem is a huge group of living organism such as plants,animals, micro-organisms in a particular area.
- An ecosystem is a community of living organisms related with the nonliving components in the environment, together interacting as a system.
- its abiotic constituents, includes minerals, climate, soil, water, sunlight, and all other nonliving elements, and its biotic constituents, consists of all its living members.
Differentiation in plants refers to the processes by which distinct cell types arise from precursor cells and become different from each other. Plants have about a dozen basic cell types that are required for everyday functioning and survival. Additional cell types are required for sexual reproduction. While the basic diversity of plant cell types is low compared to animals, these cells are strikingly different. For example, some cells such as parenchyma cells retain the potential to respond to environmental and/or hormonal signals throughout their life and, under the right conditions, can be transformed into another cell type (transdifferentiation). Other cells such as the water-conducting vessel elements undergo cell death as part of their differentiation pathway and thus can never transdifferentiate to another cell type

They are energy production, energy storage, building macromolecules, sparing protein, and assisting in lipid metabolism

If the researchers replaced the bacterial proton pump with a proton pump that was activated only by atp then less ATP would be produced when the light is on because no proton gradient would be available to produce ATP.
<h3>What is
proton gradient ?</h3>
Two quinol (4H+4e) oxidations at the Qo site result in the formation of one quinol (2H+2e) at the Qi site, creating a proton gradient (in total six protons are translocated: two protons reduce quinone to quinol and four protons are released from two ubiquinol molecules).
For the ETC to continue functioning, the energy trapped in the electrochemical gradient of protons across the inner mitochondrial membrane must also be released in some manner. ATP is created using the energy in the proton electrochemical gradient.
Chemiosmotic coupling is the process by which ATP synthesis is coupled to the electrochemical gradient of H+ across the inner mitochondrial membrane.
Peter Mitchell, who in 1961 made the initial suggestion, was given the Nobel Prize for his efforts in 1978.
