b. the amount of organisms in a unit area
c. the total number of organisms in a population
d. where and in what arrangement organisms are located Please select the best answer from the choices provided
The correct option is (d) The early solar system had large amounts of water; so, the oldest objects in the solar system should also be abundant in water.
The statement that answers the scientific questions in the form of scientific data that supports the claim is called a scientific claim. There is need for the justification of the claim. The scientific claim here is The early solar system had large amounts of water and the justification to the claim is water is found in all the primitive bodies like the comets and the asteroids and in many dwarf planets like ceres. There are many evidences that shows that there are abundant amount of water in our solar system.
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
