As electrons move along the chain, hydrogen ion are pumped from the stroma of the chloroplast into thylakoid lumen. these leads to creation of proton gradient in thylakoid lumen with the potential energy that will be used to synthesize ATP by enzyme ATPase in the process referred to as rotational catalysis. both chloroplast and mitochondria use electron transport chain to pump protons across the membrane and both enzyme ATPase to produce ATP using proton gradient created in the process of transport of hydrogen ions. the main existing between the electron transport chains of chloroplast and mitochondria is the initial source of energy. chloroplasts obtain their energy from sunlight whereas mitochondria obtain theirs from organic molecules.
Hello. You forgot to enter the necessary data for this question to be answered. The data are shown in the figure attached below:
Answer:
Red-capped Robin is the group of Robins that share a more recent common ancestor with the Norfolk Island robins.
Explanation:
Red-capped Robin is the group of Robins that share a more recent common ancestor with the Norfolk Island robins, this can be seen by the degree of genetic similarity between these two species, since the Red-capped Robin has 98.2% of genetic similarity .
When two species have the same common ancestor, these species have great genetic similarity and the more recent this ancestry is, the greater the genetic similarity between the species.
Answer:
Nitrate is the form of nitrogen most used by plants for growth and development. Nitrate is the form that can most easily be lost to groundwater. Ammonium taken in by plants is used directly in proteins. This form is not lost as easily from the soil
The correct answer is option B- sea anemone
Sea anemone belongs to group of marine animals, predator in nature. They belong to the phylum Cnidaria
Sea anemone has a foot like structure at the bottom which helps in attachment with rocks or anchor in sand but most of the species come near to the surface and float at the surface of water.
The most important and interesting factor about anemone is the presence of small tentacles around the mouth used to capture the prey.
