Answer: Herbivore that feeds on producers
Answer: feed-back
When the product of a metabolic pathway accumulates, it may be able to slow down or turn off the pathway by inhibiting the activity of an enzyme that catalyzes an early step in the pathway. This is referred to as feed-back inhibition.
Explanation:
Feed-back inhibition is said to occur when the final product of a biochemical pathway signal the inactivation of the starting materials of the pathway.
For example: when pyruvate signal the inactivation of phosphofructokinase, the glycolytic pathway gets turned off.
I believe its (B). Giving up a neutron
Carbohydrate residues attached to the membrane lipids are always positioned on the extracellular side of the membrane
Carbohydrates are significant parts of the cell membrane, present just on the external surface of the plasma layer, and are appended to proteins, framing glycoproteins, or lipids, and framing glycolipids. These carbohydrate chains might comprise 2-60 monosaccharide units and can be either straight or branched.
The carbohydrates of the membrane are engaged with cell bond and acknowledgment and go about as a physical barrier. Enormous, uncharged particles, for example, glucose can't diffuse through the membrane.
These carbohydrates structure particular cell markers, that permit cells to perceive one another. These markers are vital in the resistant framework, permitting safe cells to separate between body cells, which they shouldn't assault, and unfamiliar cells or tissues, which they ought to.
