False, that's actually backwards I believe.

Answer:
The increase in cranial or cerebral capacity inherited from the primate ancestors is the characteristic that allows the creation and use of tools.
Explanation:
The evolution of the human brain allows the creation of more complex tools.
Homo habilis was the first hominid to make tools. its size was similar to the australopithecus but its brain was twice with a cranial capacity of 650 cc. These tools were made of stone and were used by striking against each other.
In addition to several other factors, the overall risks of environmental chemicals depend on genetically determined variations in the <u>proteins</u> involved in the transport, metabolism, and excretion of these chemicals.
Environmental Chemicals
Various chemicals and compounds present in the air, food, soil, water, dust, etc are called environmental chemicals. In humans, there are more than 400 listed environmental chemicals. Most of these chemicals are already present in the environment while the others were manufactured for humans to use. Some chemicals may be harmful to all humans while others may be selectively harmful to certain individuals and they are commonly referred to as allergens. Even though there are many environmental chemicals around a human being, most of them are not harmful.
The risks involved in exposure to chemicals depend on variations in the proteins present in various metabolic functions. If the functions of the proteins are hampered then it will create a cascade of errors that may end up causing serious harm to the person.

Answer:
DNA is the evidence that biologist use to identify new type of organisms
Explanation:
Taxonomy is the system biologist use to name living things
Answer:sensory nuerone to internuerone to motor neurones
Explanation:
The sensory nuerone usually receive inputs from the receptors cells in the skin,organs,and other parts of the body.
These receptors send signals as action potential to the spinal cord to the brain.(CNS).
Synapse take place at the synaptic junctions, in the spinal cord with the internuerone.
The latter transmit the action potential to the motor neuron which synapse with the internuerone and transmita signal to the neuromuscular junction where it synapse with the muscels at the toe.
The action potentials causes influx of calcium ions and the relase of acetylcholine neurotransmitters for action potential to reach the toe muscles (effector)for contraction
