Water is a polar molecule.
Have a wonderful day :)
Heart rate is controlled by the two branches of the autonomic (involuntary) nervous system. The sympathetic nervous system (SNS) and the parasympathetic nervous system (PNS). The sympathetic nervous system (SNS) releases the hormones (catecholamines - epinephrine and norepinephrine) to accelerate the heart rate. The parasympathetic nervous system (PNS) releases the hormone acetylcholine to slow the heart rate. Such factors as stress, caffeine, and excitement may temporarily accelerate your heart rate, while meditating or taking slow, deep breaths may help to slow your heart rate.
Small segments of dna that can move from one region of a dna molecule to another are transposable elements or "transposons"
Answer:
d. Fungi have cell walls made of cellulose.
Explanation:
The cell wall is an extracellular envelope present in all vegetables and some bacteria, fungi and protozoa. Its composition varies according to the habit of each organism before the evolutionary and adaptive processes. This structure precludes morphological changes of organisms, due to its semi-rigid character, that is, cells cannot change shape as a result of spatial impediment limited by the rigidity of the cell wall.
In plants, the cell wall is basically composed of the cellulose polysaccharide, which forms the cellulosic wall. In most fungi, the wall is formed by chitin. Therefore we can state that the statement that does not describe a way in which fungi differ from plants, among the options given is "the fungi have cell walls made of cellulose."
