When a neuron carries the electrical potential of -70 millivolts, it is in the state called RESTING POTENTIAL. At the resting stage of the neuron, the inside of the neuron is 70 millivolts less than the outside. At this stage, there are more sodium ions outside the neuron and more potassium ions inside the neuron.

Explain how natural selection and a color mutation associated with greater exoskeleton strength interact to result in evolutiona
KIM [24]
<h2>Evolution of Beetle Population. </h2>

Explanation:

  • Natural selection is the reproduction of people because of contrasts in phenotype and the differential survival.
  • It is a key system of development, the adjustment in the heritable qualities normal for a populace over ages.
  • Variety exists inside all populaces of organisms.For model, tree frogs are in some cases eaten by<em> snakes and birds.</em> This clarifies the appropriation of Gray and Green Tree frogs.  
  • The  transformation caused  qualities with parents for a quality for dark colored hue and for the bright green coloration. That would make the qualities for <em>darker creepy crawlies</em> progressively visit in the populace.
  • A few people from a populace of darker beetles. It is connected to the populace of green beetles.

Sholpan [36]

Answer:

The original water sample contains 830,000 cells per milliliter.

Explanation:

A sample of well water is tested for its bacterial content in a plate count assay. A one-milliliter sample of the water is diluted in a 1:10 dilution series. One milliliter of the fourth dilution tube is plated in a pour plate. After incubation, the plate has 83 colonies, indicating that the original water sample contained 830,000 cells per milliliter.

Charles Darwin observed a unique beak size and shape in the finch population of each of the Galapagos Islands that he visited. 4
Rasek [7]

Natural selection would probably favor different varieties in the different islands. In other words, beaks changed as the birds developed different tastes for fruits, seeds, or insects picked from the ground or cacti (due to lack of food resources). Long, pointed beaks made some of them more fit for picking seeds out of cactus fruits.

100 POINTS!!! ANSWER ASAP [5 SENTENCE ANSWER] Explain the relationship among distance, mass and gravitational force between any
Karolina [17]
Since the gravitational force is directly proportional to the mass of both interacting objects, more massive objects will attract each other with a greater gravitational force. So as the mass of either object increases, the force of gravitational attraction between them also increases. If the mass of one of the objects is doubled, then the force of gravity between them is doubled. If the mass of one of the objects is tripled, then the force of gravity between them is tripled. If the mass of both of the objects is doubled, then the force of gravity between them is quadrupled; and so on.

Hope this helps.
