Answer:
4.) This means that height in a rat is controlled by many different genes.
Explanation:
Answer;
Iodine
A diffuse, nontoxic goiter is usually due to a lack of Iodine in the diet.
Explanation;
-A diffuse non-toxic goiter is an enlargement of the thyroid gland without nodularity. It occurs in an endemic and sporadic distribution. It does not result from an inflammatory or neoplastic process and is not associated with abnormal thyroid function.
-Simple nontoxic goiter, which may be diffuse or nodular, is noncancerous hypertrophy of the thyroid without hyperthyroidism, hypothyroidism, or inflammation. Except in severe iodine deficiency, thyroid function is normal and patients are asymptomatic except for an obviously enlarged, non tender thyroid.
Chloroplast is the organelle and Chlorophyll is the thing that makes it green.
Explanation:
The resting membrane potential is negative due to the buildup of more sodium ions outside the cell than potassium inside.
Potassium ions readily diffuse out of the cell more quickly than sodium due to the presence of more channels which allow for potassium leakage. The sodium pumps in neuronal membranes bring more K+ ions into the cell; with every three sodium ions pumped out two potassium ions are brought in- this is in order to maintain the negatively charged membranes within the cell along with the resting potential.
Further Explanation:
Neurons have unique structures which aid in facilitating communication by sending and receiving electrical signals very efficient. Parts of a neuron are separated into the
dendrites which receive messages from other neurons allowing them to pass and some of the cell body which contains typical cell components like the nucleus, endoplasmic reticulum and mitochondria.
The axon is an insulated (by the myelin sheath) tubular structure which acts as a bridge to price impulses to other neurons these also contain axon hillocks which are junctions between the axon and cell body
Synapses are junctions where axons connect to dendrites of other neurons at these junctions chemical reactions occur in order to facilitate the passage of information as chemical signals.
There are several neuron types which include sensory motor and into neurons which bridge the two.
- The refractory period describes a period between the initiation of an action potential where Na+ channels are closed, and immediately after the action potential’s peak. Action potentials would require an influx of more positively charged ions; these must be more than a specific threshold in order to have the cells send along more action potentials which helps with figuring out stimulus intensity.
- Potassium ions readily diffuse out of the cell more quickly than sodium due to the presence of more channels which allow for potassium leakage. The sodium pumps in neuronal membranes bring more Na+ than K+ ions into the cell; with every three sodium ions pumped out two potassium ions are brought in- this is in order to maintain the negatively charged membranes within the cell along with the resting potential
