Answer:
Chemical properties of water are neutral pH and weak ionization while physical properties of water are that it is present in solid , liquid and gas form and it is a tasteless and odorless molecule.
Explanation:
Water is also called universal solvent due to its polar nature. Water has a neutral pH when it is present in pure form but with the addition of salts and other impurities, pH of water changes. Water has weak ionization rate. Water is present in liquid form at room temperature but increasing in temperature , they transform in gaseous state.. Water is a taste less molecule and having no odor or smell.
Answer:
: Notice the rate of diffusion increases as the concentration gradient increases. If the concentration of molecules outside the cell is very high relative to the internal cell concentration, the rate of diffusion will also be high.
For Ms. Cantu, the GRB7 gene is not expressed in malignant breast tissue while the ESR1 gene is upregulated in such tissue.
Upregulated genes are shown by the colour red.
Down-regulated genes are shown by the colour green.
Non-differentially expressed genes are indicated by the colour yellow.
Absence of expression is shown by the colour black.
Hence from the table and colours ESR1 The GRB7 gene is not expressed, and the gene is upregulated.

Somatic sensory division of the pns is responsible.
<h3>
Somatic sensory division</h3>
A component of the peripheral nervous system known as the somatic nervous system (SNS) or somatic sensory division, sometimes known as the voluntary nervous system, is responsible for the voluntary control of skeletal muscle-based motions of the body.
The somatic sensory division is made up of motor nerves with efferent nerve fibers that relay motor commands from the central nervous system (CNS) to cause muscle contraction and sensory nerves carrying afferent nerve fibers that relay feeling from the body to the CNS.
Each voluntary muscle system in the body as well as the process of voluntary reflex arcs are under the direction of the somatic sensory division.
The top cell bodies of motor neurons are the starting point of the basic sequence by which nerve signals travel within the efferent somatic sensory division.

The postsynaptic potential is the membrane potential, which takes place in the neuron present post synapsis (after the chemical synapse). The presynaptic neuron releases neurotransmitter, which causes the firing in the postsynaptic neurons.
The firing of the post synaptic neuron depends on the excitation and inhibition inputs received from the presynaptic neuron. The firing is the resultant of the summation of excitatory and inhibitory potential. In case, the excitatory potential is greater than inhibitory potential, the post synaptic neuron would be excited. in case, inhibitory potential is greater than excitatory potential, then the post synaptic neuron would be inhibited.
Hence, the correct answer is option d.
