Answer:
The correct option is B) a pattern of biological functioning that occurs on a 24-hour cycle.
Explanation:
Biological rhythm is defined as the regular variation of an organic function related to the course of time, circadian biological phenomena (around the day), are those with a period of approximately 24 hours.
Circadian rhythms are physical, mental and behavioral changes that follow a daily cycle (the biological rhythm), and that respond primarily to light and darkness in an organism's environment. This cycle close to 24 hours, allows to recognize the sleep-wake phenomena and their homeostatic action, in the systemic processes of every living being. The circadian system is composed of photoreceptors, pacemakers and efferent pathways that allow a regular functioning of the sleep and wakeful state.
Answer:
Organic compounds contain carbon and hydrogen (which may be replaced by other atoms).
Answer:
The transitional epithelial tissue is perfect for bladder function because it has the ability to stretch.
When the bladder is empty, the cells have a cuboidal shape. When the bladder is full, the cells have a flat shape.
Explanation:
Transitional epithelial tissue is the tissue that makes up the entire bladder and some organs of the urinary system. This tissue has the ability to allow the organs covered by it to have the ability to change shape and size, because this tissue allows these organs to stretch, so it is the perfect tissue to cover the bladder.
As we know, the bladder is the organ responsible for storing urine. When it is filled with urine, the bladder stretches, at that moment, the bladder cells are compressed and assume a flat, stretched shape. When it is empty, the bladder shrinks in size, becoming "wilted", at that moment, its cells assume a cuboidal shape.
Answer: HI your question is incomplete but i will provide a general answer that can help you
answer : Permeable Rock layers allow the flow of fluid like substances through them, While Impermeable rock layers do not allow the flow of fluid like substance through them.
Explanation:
Permeable rocks are rocks containing pores through Fluid like substances can penetrate through in the rocks. examples of Permeable rocks are ; Sandstones and Chalk
While an Impermeable rock is a rock that does not allow the flow of fluid like substance through it due to the absence of pores in its rock layers . examples of such rock are ; Clay and marble
Although some permeable rocks might exhibit low level of permeability as well but generally Rock sample with pores are classified as permeable rock layers.
