Answer:
The correct answer is D. On the plasma membrane.
Explanation:
Prokaryotes do not have mitochondria to synthesize ATP but ATP synthesis takes place in prokaryotes on the plasma membrane as the plasma membrane contains the enzymes that are required for ATP synthesis.
The process of ATP synthesis is just like in the mitochondria. NADH helps in building the proton gradient in the outer portion of the membrane by the help of electron carriers embedded in the plasma membrane. Then these protons come back in the cytoplasm through ATP synthase enzyme complex.
This entry of protons helps in the generation of ATP from ADP and inorganic phosphate with the help of ATP synthase enzyme. Therefore the correct answer is D. On the plasma membrane.
A scientist named Hans Christian Gram made 2 kinds of bacteria that is based on their differences in the cell walls. The gram positive and the gram negative.There are differences on these 2. One of it is that Gram negative are more resistant with antibodies compared to the gram positive. Example of these would be pseudomonas aeruginosa while for the positive would be Staphylococcus. Another difference between the 2 would be for flagellar structure in gram negative have 4 rings while positive has only 2.
Answer:
extant; extinct.
Explanation:
A species is a group of individuals that can interbreed to produce fertile and viable progeny. A species may be present on the earth and is surviving or may not be present now on the earth and have become extinct due to one or more reasons. Extant species are the species living on the earth in the present time while extinct species do not exist now. For instance, <em>Plateosaurus engelhardti</em> is a species of dinosaurs that survived on the earth during the Triassic period but does not exist now. On the other hand, <em>Homo sapiens, Apis indica</em> are some of the examples of the extant species that are surviving on the earth.
Different structures of cells can exist within the same organism. Different structures of cells may be indicative of different organelles presents different structures mostly arise due to different functions of the cell, as how structure of cells always complement the function of cells hence it is most it is mostly likely the last option that the cells have different functions
Answer:
the production of new living organisms by combining genetic information from two individuals of different types (sexes). In most higher organisms, one sex (male) produces a small motile gamete which travels to fuse with a larger stationary gamete produced by the other (female).
