Answer:
K+ ion concentration is high inside the cell under resting membrane potential.
Explanation:
Neurons generates electrical signals across its membrane called the resting potential. The resting potential is determined by the concentration gradient of ions and membrane permeability to ions.Therefore, in a resting neuron there are a concentrations gradient for Na+ and K+ ions across the membrane. The movement of ions towards the gradient through channels . The ions' movement create a resting potential by separating its charge.
Living things are placed into certain kingdoms based on how they obtain their food, the types of cells that make up their body, and the number of cells they contain. The phylum is the next level following kingdom in the classification of living things.
Answer:
B
Explanation:
process by which a population of organisms who are best adapted change over time is the answer
In an experiment, the respiration rate of a goldfish is measured by placing the goldfish in cold water and then the respiration rate is measured again, the cold water is the independent variable.
<h3>What is an independent variable?</h3>
Independent variable is the variable of an experiment that is manipulated or changed while the dependent variable is the variable that is measured or recorded in an experiment.
According to this question, the respiration rate of a goldfish is measured. The goldfish is placed in cold water and then the respiration rate is measured again.
The cold water is the independent variable because it is the variable that is changed in terms of temperature difference.
