Answer:
present
Explanation:
Otherwise the only similarity is that they are organelles, and can generate themselves.
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
The nitrogenous bases guanine and adenine are called a. purines.

Many biological systems classify the organism based on the cells, reproduction, simplicity and complexity. The discovery of the new species and arrangement based on the hierarchy led to the change.
<h3>What was the new classification system?</h3>
Aristotle gave the most primitive biological hierarchical classification system that was replaced by the system of the Linnaeus. He gave the classification based on the taxonomy groups.
With time many new organisms and species were discovered that did not fit in Aristotle's classification system. Hence, with time new systems were established to classify the organism based on many new parameters.
Therefore, option A. new system was established to classify the new organism discovered.
