Answer:
A) The striations are due to the orderly arrangement of actin and myosin
Explanation:
Smooth muscles are non-striated involuntary muscles which are found in the walls of stomach, urinary bladder, blood vessels...Smooth muscle tissue is composed of spindle-shaped muscle cells with single central nucleus. Like the other two type of muscles (cardiac and skeletal), smooth muscles also have four main functions:
- Contractility-ability to contract. In the case of skeletal muscles it is voluntary, while in cardiac and smooth muscles it is unconscious.
- Excitability-ability to change membrane potential usually by the influence of nervous impulse.
- Extensibility-the capacity to lengthen
- Elasticity-ability to change its length and then return to previous.
Answer:
negative
Explanation:
electrons have negative charges and elements are usually neutral. so if you add a negative, it will make the atom have a negative charge. think of it as a seesaw, in an atom there are 10 protons and 10 electrons, if an 11th electron friend joins, the seesaw will lean more towards the negative side now. :) hope i helped
Answer:
urinary bladder does not help in reproduction
The answer to this question would be reuptake
Reuptake is a reabsorption of the neurotransmitters that had been released. Reuptake is important because if the neurotransmitter isn't removed, they can repeatedly induce a signal.
Some drug works by inhibiting this reuptake mechanism like serotonin reuptake inhibitor. By doing this, the drug will increase the number of the neurotransmitter since it won't reabsorbed.
