<h2>Rates of Population Growth</h2>

Explanation:

  • <em>Growth is precisely defined for microbes as increment in number of cells, not size</em>
  • Development rate is change in cell numbers per unit time. Age time is the time it takes for a cell to double. Also called doubling time.
  • Development rates allude to the rate change of a particular variable inside a particular time span and given a specific setting.  
  • r = (births-passings)/populace size or to get in rate terms, <em>simply increase by 100</em>
  • The populace is so a lot greater, a lot more people are included. In the event that a populace develops by a consistent rate for every year, this inevitably indicates what we call exponential growth..

Assuming one nerve impulse must end before another can begin, what is the maximum firing rate of a nerve in impulses per second?
pav-90 [236]

Answer:

The correct answer is - 10³ seconds.

Explanation:

The nerve impulse is an electrical signal in which fluctuation in membrane potential occurs and forms an electrical signal that takes place that travels along the axon to the synapses.

Suppose a nerve impulse starts only when the first impulse ends according to the question so the one impulse last for the 10⁻³ second or 1 ms.  

Thus,  the nerve impulse fires per second will be equal to impulse generate in each second which is 1/10⁻³ = 10³.

Thus, the correct answer is - 10³ impulse per second or 1000 impulse per second.

What are sunspots?
mel-nik [20]
Sunspots are temporary phenomena on the Sun's photosphere that appear as spots darker than the surrounding areas. They are regions of reduced surface temperature caused by concentrations of magnetic field flux that inhibit convection. Sunspots usually appear in pairs of opposite magnetic polarity.
