Answer:
The reason why animals <u>cannot synthesize oxaloacetate</u> is because the fatty acids which they produce, are not able to create glucose (oxaloacetate).
Explanation:
The fatty acids in animals need to be converted to acetyl-CoA first, but this acetyl won't convert into oxaloacetate, in comparison to plants, that use the glyoxylate cycle, that allows them to produce the mentioned glucose.
Answer:
d. secondary endosymbiosis.
Explanation:
- When a living cell acquires another organism that eventually becomes a part of this cell, this process is known as primary endosymbiosis.
- When an organism that has already undergone primary endosymbiosis engulfs another eukaryotic organism then this process is known as secondary endosymbiosis.
- Secondary endosymbiosis has been known to occur in plastids because of which they are surrounded by two membranes. This bilayer is present because one of the layers is the original outer membrane of the organism and the other membrane is that of the organism that has been engulfed.
