Answer:
60 beats per minute
Explanation:
heart rate is measured in minute, if he counted for 10 seconds, he would need to multiply that number by 6 to get his resting heart rate. 10×6=60
Answer:
Atoms are electrically neutral as a result of having an equal amount of positive (due to the protons) and negative (due to the electrons) charges on it.
An ion generally is an electrically unbalanced atom (i.e an atom with a net charge on it)
A negative ion called an anion is produced when an atom gains an extra electron from a neighboring atom, giving it an extra negative charge. This can be produced by ionization with a radioactive radiation or simply by dissolution.
A positive ion is called a cation and it is produced when an atom loses electron to a neighboring atom. The loss of this electron causes the positive charges to outweigh the negative charges in the atom. Cations can be produced by radioactive radiation ionization of an atom or by simple dissolution.
The subatomic particle that is negative is the 'electron'.
Answer:
A threshold level depolarization.
Explanation:
In a neuron, the action potential threshold is known as the point of depolarization where the neuron fires, when the neuron reaches a point, it will fire and if it does not reach the point of depolarization, it will not fire and it helps to transmit the information to another neuron.
A neuron transmits the information with the help of electric impulses which are sent through its axon. When a neuron in an inactive phase, more +ve charged ions recline outside the axon membrane. In the process of stimulation, the axon membrane admits more Na+ ions and providing the neuron more +ve charge.
DNA to 8. the genetic blueprint for all cells
Nucleus to 5. acts as the "brain" of a cell
Connective cells to 9. tendons, blood, and fat are examples of these cells.
Epithelial tissues to 6. designed to regulate temperature, secrete lubricants, and protect the body from harmful substances.
Cytoplasm to 7. fluid like substance in a cell
Organelles to 3. structures that perform special functions within a cell
These are the only ones I know.
Answer: None of the Above.
Explanation: Protista can be anything, and are basically off-brands, Plant based, Fungi Based, Animal Based, Etc.So the ENTIRE kingdom cant be Prokaryotic or Eukaryotic.
Animals and Plants aren't Single-Celled because you can see them.
Fungi are Eukaryotic
