There are five characteristics of Muscles; namely Responsiveness, Conductivity, Contractibility, Extensibility and elasticity.
Assigning each example to the universal muscle characteristic being described;
Conductivity; (electrically stimulating a muscle) Local electrical change triggers a wave of excitation that travels along the muscle fiber.
Contractibility; Shortens when stimulated
Elasticity; Returns to its original resting length after being stretched,
Extensibility; capable of being stretched between contractions.
Responsiveness; to chemical signals, stretch, and electrical changes across the plasma membrane.
Answer:
is the movement of substances due to random thermal molecular motion. is the diffusion constant, representative values of which are found in [link]. Osmosis is the transport of water through a semipermeable membrane from a region of high concentration to a region of low concentration.
Explanation:
Forms solid that are relatively insoluble and nontoxic
Uric acid is product of the metabolic breakdown of the purine nucleotides. It is considered as a normal component of urine. In birds and reptiles the evolved the ability to convert toxic ammonia into uric acid or guanine rather than urea. These organisms are called as uricothelic organism because they have the ability to convert toxic ammnonia to uric acid instead of urea. Uric acid is less toxic than ammonia.
The statement is true, the four blood types result from various combinations of the three different ABO alleles, giving rise to A, B, AB and O as the four universal blood types.
The above is not an example of sexual selection because sexual selection is about differential success in acquiring males.In sexual selection one biological sex chose mates of other sex to mate with. and compete with members of the same sex for access of members of opposite sex
