Answer:
Explanation:
Firstly; the missing figure is attached in the diagram below.
Ligand A and ligand B can cause identical cellular responses in a cell due to the fact that there are cross-linkages in the various enzymatic activities taking place in the receptor proteins located in the plasma membrane.
This implies that a particular compound in the cell signaling in eukayortes can be triggered by some mechanism. For example as we can see right in the diagram; The ligands can trigger the G-protein in the plasma membrane which result into increase in cAMP.
In addition to that; IP3/DAG pathway can signal and trigger the calcium influx moving into the cytoplasm from the endoplasmic reticulum
Answer:
they help it thrive and live because it just goes in a circle sun grows plants plants feed herbivores, herbivores feed omnivores then it eventually gets to the top of the food chain and when the top of the food chain dies it decomposes and gives the ground fertilizer and starts all over again
Explanation:
because it is the circle of life
Sorry I don’t know that one
Answer: NATURAL SELECTION is the term used to describe the greater relative survival and reproduction of individuals in a population that leads to evolutionary change.
Explanation: Those individuals with characteristics (either physical or behavioral) that give them an advantage in a particular environment, are more likely to thrive and survive to breed, passing along their characteristics. Likewise, those who are disadvantaged are less likely to survive to breed and pass along their traits.
