Natasha's model of cellular respiration shows an aerobic pathway consisting of glycolysis, the Krebs cycle, and the electron transport chain.

Explanation:

Options for this question are:

An aerobic pathway consisting of glycolysis and fermentation.An aerobic pathway consisting of glycolysis, the Krebs cycle, and the electron transport chain.An anaerobic pathway consisting of glycolysis and fermentation.An anaerobic pathway consisting of glycolysis, the Krebs cycle, and the electron transport chain.

Cellular respiration is the process of energy production that occurs in mitochondria. This process requires energetic substrate, such as glucose.

Glucose is converted to pyruvate by the process of glycolysis, which occurs in the cytoplasm. This pyruvate is then transformed into acetyl-coa.

In the presence of oxygen, energy production in the mitochondria depends on the Krebs cycle, which starts with successive transformations from Acetyl-CoA to acetate and then to Citrate, through oxidation processes. These oxidative processes are necessary for electron transfer to occur.

Thus, cellular respiration in the presence of oxygen involves an aerobic pathway consisting of glycolysis, the Krebs cycle, and the electron transport chain.

That is true tge cactus as a structural adaptation to its envirinment has it leaves reduced to spines. but this doesnt mean it cant produce food it produces food because of the presence of chlorophyll in its stem

c. earths continental crust is thicker than its lithosphere.

because, the lithosphere is the outermost layer of the earth/ 100 km thick and is defined by its machanical properties.the lithosphere contains oceanic and continental crust that varies in age and thickness across locations and geologic time. the lithosphere is the coolest layer of the earth in terms of temperature. the term lithosphere should not be confused with the use of "geosphere" which is used to indicate all of earth systems, including the atmosphere, hydrosphere and biosphere. the surface of the earth can be divided into the continental crust and the oceanic crust. the continental crust is made mostly of granite while the oceanic crust is made of basalt. the average thickness of the continental crust is 25 miles and the average thickness of the oceanic crust is 5 miles. three types of rock, igneous, sedimentary, and metamorphic, make up the surface of the earth. that's why 3 option is preferable.
