Answer:
Option E, C tactile (CT) afferent
Explanation:
Whenever a slow moving gentle touch experienced, the response is due to the nerve fibers called C-Tactile afferents (CTs).
C-Tactile afferents (CTs) are unmyelinated mechanoreceptors of low threshold and low conduction velocities.
In humans, CT neurons are found in hairy skin.
The pleasant feeling observed during a slow gentle touch is due to the interaction of
CT neurons project to the insular cortex in the brain
Hence, option E is correct
Antheridia- is reproductive that produces MALE gametes. AND
Archegonia- is reproductive that produces LADIES gametes
Answer:
Nitrogen fixation (N2 to NH3/ NH4+ or NO3-)
Nitrification (NH3 to NO3-)
Assimilation (Incorporation of NH3 and NO3- into biological tissues)
Ammonification (organic nitrogen compounds to NH3)
Denitrification(NO3- to N2)
Explanation:
The answer is A.The calcium atom must bond with an atom of high electronegativity (like fluorine) because the higher electronegativity atom will bully the low electronegativity atom and take away its electrons.
These are the choices:
A. an atom with a high electronegativity, like fluorine
B. another atom with a low electronegativity, like lithium
C. another atom that would like to share electrons
D. no other atoms because it's too weak to bond with anything
