The density of cristae is higher in the mitochondria of the cell with higher rates of respiration.
The folds found inside the inner mitochondrial membrane are called mitochondrial cristae.
These folds provide a larger surface area where chemical processes, like redox reactions, can occur.
Due to the fact that the ETC enzymes are encased in the inner mitochondrial membrane, an increase in surface area through the production of many cristae may result in higher rates of respiration.
The inner membrane is folded into cristae to boost the mitochondrion's ability to produce ATP.
These folds enable the mitochondrion to contain many more ATP synthase and electron transport chain enzymes.
Hence, the density of cristae is higher in the mitochondria of the cell with higher rates of respiration.

#SPJ1
The CSF is confined between the pia mater and arachnoid mater
Answer:
The answer is B. Eumetazoa and Lophotrochozoa.
Explanation:
The difference between the lophotrochozoa and deuterostomia is the way they develop on the cigote phase.
Lophotrochozoa are a clase that has a spyral shape.
The literature mentions that the phylum Cycliophora are coelomates and their embryos undergo spyral cleavage which is a common characteristic of the Lophotrochozoa.
The Eumetazoa clase are conformed on organisms whit his own tissues and the phylum Cycliophora has a "U-shaped intestine that brings it´s sanus close to the mouth".
In conclusion, the correct answer is that the phylum Cycliophora gets into the clases Eumetazoa and Lophotrochozoa.
A for the first one and D for the second
Answer:
an advantage is living cells can be examined in their natural state without previously being killed, fixed, and stained
