The question pertains to vision and somatosensation, two sensorial systems that detect physical energies. Vision pertains to the detection and interpretation of light patterns, while somatosensation involves responses to various stimuli such as temperature, pain, pressure, vibration, and internal body movements and positions. Both systems require stimuli to reach a certain energy level, known as the absolute threshold, to be detected.
The ability to detect physical energy through our visual or touch systems refers broadly to our senses, specifically vision, and somatosensation. These are crucial to human functionality, allowing interaction and understanding of the environment. Vision is the ability to detect light patterns from the outside environment and interpret them into images. It involves converting stimuli such as light into an electrical signal in the nervous system through a process called sensory transduction.
On the other hand, our sense of touch, referred to as somatosensation, encompasses reactions to stimuli like temperature, pain, pressure, vibration, body movement (kinesthesia), and the position of bones, joints, and muscles (proprioception). Proprioception and kinesthesia are part of our general senses, distributed throughout the body with receptor cells within the structures of other organs contributing significantly to autonomic functions. This system also uses sensory transduction to convert stimuli into neural signals.
Both of these sensory systems operate on principles of threshold sensitivity, successfully detecting stimuli only once it reaches a certain minimum energy level. This is known as the absolute threshold.

passive immunity
innate or natural immunity
Answer: The correct answer for the full in the blank is "Passive immunity".
Passive immunity is the transfer of active humoral response (with ready made antibodies) into the individual.
It can be naturally acquired by mother during gestation period (where antibody from mother is transferred to fetus via placenta) and through breast feeding (antibody transferred through breast milk).
Thus, antibodies transferred to child from mother are part of Passive immunity.
Answer: any small molecule that can bind in a specific manner to a larger one
Explanation:
A ligand can be simply defined as an ion or a molecule that binds to usually a metallic element, in a coordination or complex compound.
The term "ligand" refers in cell biology to any small molecule that can bind in a specific manner to a larger one.
The functional significance of ligand-receptor binding in biological and molecule cell mechanisms is based on the fact that these binding activates signaling pathways required for the metabolism of a given cell.
Therefore, with this data, we can see that ligand receptor binding is fundamental during signaling cascades and it involves the activation of a specific metabolic pathway.

Human liver cells make proteins that promote homeostasis that neurons do not.
B.
Different species of bacteria have different shapes and structures to their cells.
C.
The DNA in the cell nucleus of chimpanzees and humans are 98% identical.
D.
Prokaryotes do not have nuclei, but they can still carry out the basic functions of life.
Answer:
A
Explanation:
Human liver cell make proteins that promote homeostasis that neurons don't have.
Homeostasis is the regulation of an internal steady environment.
