The interactions can be harmful because they can poison the organisms and they can be helpful because they can help improve the organisms surroundings ex. food/ water supply.
Answer:
1000, 2000 and 3000.
Explanation:
The example given in the question is of a DNA with 4000 base pairs and it is being cut at 1000 pairs, 1500 pairs and 3000 pairs. So the lenghts of the segments that are cut from the original spiral are 1000, 500, 1500 and 1000 respectively. And the information that only the linear fragments are being produced is given to us in the question so the sizes of DNA expected would be 2000, 1000, 3000 and 2000 again respectively.
I hope this answer helps.
The light independent reactions send NADP+ and ADP back to the light dependent reaction to convert them into ATP and NADPH. The light-independent reactions send the ATP and NADPH made during the light dependent reactions to the dark reaction to make glucose.
Answer:
b. brings the postsynaptic cell to the chloride equilibrium potential
Explanation:
Gamma-aminobutyric acid (GABA) is one of the most important neurotransmitters, chemicals that brain cells use to communicate with each other. In fact, it is the most frequent inhibitory neurotransmitter. Inhibiting neurotransmitters decrease the chances that a nerve impulse will be triggered.
The main function of GABA as an inhibitory neurotransmitter is to slow down brain activity. It is also involved in vision, sleep, muscle tone and motor control.
It is widely distributed both inside and outside the central nervous system. It is found in the intestines, stomach, bladder, lungs, liver, skin, spleen, muscles, kidneys, pancreas and reproductive organs.
In vertebrates, GABA leads the postsynaptic cell to the chloride equilibrium potential. Through it, chloride ions flow out of the cell to achieve equilibrium.
