Answer:
The inside is becoming positive.
Explanation:
The membrane potential may be defined as the difference in the electric potential between the outside and inside of the cell. This potential difference is important for the conduction of nerve impulse.
The depolarization of the cell occur due to the movement of sodium ions inside the cell. The depolarization of the cell changes the membrane potential from -70mV to +30mV. The inside of the cell become more positive than outside of the cell.
Thus, the correct answer is option (a).
It is a metabolic process that is one of the main parts of cellular respiration
Answer:
Iodine
Explanation:
This is a trace element needed for the synthesis of the two thyroid hormone ; T4- thyroxine and T3-triiodothyronine. Four iodine molecules are added in T4 synthesis, and three for T3 synthesis. Generally T4 is the major hormone produced, but biologically transformed into active form T3.
Iodine majorly and selenium are the two trace elements needed for thyroid hormones synthesis. Therefore required amount of iodine is important in daily diet. iIn adequate supply of this leads to under production of iodine called hypothyroidism. poor brain development ( especially in kids),and goiter.
Sea foods . eggs, poultry seaweeds are rich sources of iodine.
Conversely, when excessive amount is present in the blood, autoimmune thyroid diseases can occur,including cancer developments in the thyroid gland due to hyper cell activities.
You have transcription in which DNA is transcribed into mRNA , then there is Translation in which mRNA is translated into proteins, in other words mRNA translated into amino acids that are going to be bonded together to become a protein
This process is called melting. When a solid melts, it turns into a liquid.
