The series of events in which a carbon dioxide stimulus is received by a cell and converted into a molecular signal.

The directed movement of a motile cell or organism, or the directed growth of a cell guided by a specific chemical concentration gradient. Movement may be towards a higher concentration (positive chemotaxis) or towards a lower concentration (negative chemotaxis).

The series of molecular signals generated as a consequence of a G protein-coupled receptor binding to its physiological ligand, followed by activation of guanylyl cyclase (GC) activity and a subsequent increase in the concentration of cyclic GMP (cGMP).

The sequence of reactions within a cell required to convert absorbed photons into a molecular signal.

Behavior that is dependent upon the sensation of chemicals.

The directed movement of a motile cell or organism in response to environmental oxygen.

Any process that increases the frequency, rate or extent of gene expression. Gene expression is the process in which a gene's coding sequence is converted into a mature gene product or products (proteins or RNA). This includes the production of an RNA transcript as well as any processing to produce a mature RNA product or an mRNA or circRNA (for protein-coding genes) and the translation of that mRNA or circRNA into protein. Protein maturation is included when required to form an active form of a product from an inactive precursor form.

Any process that decreases the rate, frequency or extent of cGMP-mediated signaling. cGMP-mediated signaling is a series of molecular signals in which a cell uses cyclic GMP to convert an extracellular signal into a response.

Any intracellular signal transduction in which the signal is passed on within the cell via calcium ions.

Any process that modulates the rate, direction or extent of axon extension.

Any process that increases the rate of growth of all or part of an organism.

Behavior that is dependent upon the sensation of temperature.

Behavior that is dependent upon the sensation of temperature.

The behavior of an organism in response to an odor.

The behavior of an organism in response to an odor.

The directed movement of a motile cell or organism in response to a temperature gradient. Movement may be towards either a higher or lower temperature.

The directed movement of a motile cell or organism in response to a temperature gradient. Movement may be towards either a higher or lower temperature.

Any process that modulates the frequency, rate or extent of neuron differentiation.

Any process that activates or increases the frequency, rate or extent of transcription from an RNA polymerase II promoter.

The process, occurring above the cellular level, that is pertinent to the reproductive function of a multicellular organism. This includes the integrated processes at the level of tissues and organs.

The process in which the anatomical structures of a neuron projection are generated and organized. A neuron projection is any process extending from a neural cell, such as axons or dendrites.

The series of events in which a chemical stimulus is received and converted into a molecular signal as part of sensory perception.

Any process that results in a change in state or activity of a cell or an organism (in terms of movement, secretion, enzyme production, gene expression, etc.) as a result of a stimulus indicating increased oxygen tension.

Any process that results in a change in state or activity of a cell or an organism (in terms of movement, secretion, enzyme production, gene expression, etc.) as a result of a stimulus reflecting the presence, absence, or concentration of oxygen.

The process in which a cation is transported across a membrane.

The component of a membrane consisting of the gene products and protein complexes having at least some part of their peptide sequence embedded in the hydrophobic region of the membrane.

A neuron projection that has a short, tapering, morphology. Dendrites receive and integrate signals from other neurons or from sensory stimuli, and conduct nerve impulses towards the axon or the cell body. In most neurons, the impulse is conveyed from dendrites to axon via the cell body, but in some types of unipolar neuron, the impulse does not travel via the cell body.

An ion channel complex through which cations pass.

Proximal part of the ciliary shaft to which the inversin protein (also called Inv) specifically localizes. The inversin compartment appears to have a different protein composition than the rest of the cilium, although there is no structure that separates it form the distal part of the cilium.

A cilium which may have a variable array of axonemal microtubules but does not contain molecular motors.
