Bryophytes are non vascular plants which include, mosses, liverworts and hornworts. They are seedless and lack specialized water conducting tissues.
Vacular plants are those plants that use specialized tissues to transport food and water to all parts of the plant. They have a root system, vascular system and also a shoot system. The dominant stage of the life cycle in vascular plants is the sporophyte.
Answer:
B: sample 4
Explanation:
This is because amino acids are basic units for proteins
The same receptor that responds to norepinephrine also respond to epinephrine, increasing the action of both. Adrenal medulla is NOT affected by the parasympathetic division of the autonomic nervous system (ANS
Answer:
Similarities: both are chemical messengers, both can have (but don't necessarily have) similar structures (made from amino acids), both can be produced by the central nervous system (hypothalamus produces some hormones), certain molecules can act as both hormones and neurotransmitters (example: norepinephrine).
Differences: neurotransmitters are released by neurons across a synaptic gap, have very short distances to travel, and act very quickly on the neighboring cell. Hormones are released by glands and often have to travel longer distances, which means that they are slower-acting. Also, hormones are typically used for regulation (negative feedback) while neurotransmitters are used for stimulation of a neighboring cell.
Explanation:
Answer:
strengths are it's simple and easily understood and limitations is that it cant maintain simplicity if it's more descriptive
