Answer:
The evolutionary success of this group results from its 1- small size, 2- simplicity and 3- fast reproduction rate
Explanation:
Bacteria are evolutionarily successful organisms that makeup about 15 percent of all biomass on Earth, and they occupy almost all habitats in nature. The small size of these unicellular organisms facilitates the exchange of nutrients and waste products with the surrounding environment. In addition, the relative simplicity of bacteria also facilitates the assembly of cell structures as well as a fast reproduction rate by the fast division of single cells. All these features are critical in order to understand the rapid evolution rate observed in this group.
Answer:
Letter A. G-protein coupled receptor
Explanation:
G protein-coupled receptors are a large protein family of transmembrane receptors that pick up extracellular signals and activate signal transduction pathways within the cell. They start this transduction through a chain of events triggered by phosphorylation.
In this question, we may be confused by the options that involve protein kinase, but we have to consider only cell surface receptors, as the request in question.
scientists who can consult with environmental scientists in such cases are:
b. a botanist
<h2>Further Explanation
</h2>
a botanist is a scientist who is an expert in the field of plants. In this way, in botany, all the knowledge learned about biologies, such as genetics, reproduction, growth, metabolism, development, interaction with biotic components and abiotic components, and evolution associated with plants.

The cell body of the preganglionic neuron in this figure could be located in
the central nervous system.
Preganglionic neuron are nerve fibers which connect the central nervous
system to the ganglia. This connection help in the relay of impulses
between different components of the nervous system.
All preganglionic neuron are located in the brain or spinal cord which make
up the central nervous system which explains why it's the most appropriate
choice.
