For the given quadratic equation convert into vertex form, find the vertex, and find the value for x=6. Show your work.y=-2x^2 + 2x+ 2

Answers

Answer 1
Answer: A quadratic equation has the general form of: 

y=ax² + bx + c

It can be converted to the vertex form in order to determine the vertex of the parabola. It has the standard form of:

y = a(x+h)² - k

where h, k are the vertex points.

y=-2x^2 + 2x+ 2
y=-2(x^2 - x) + 2
y + 1/4 = -2 (x^2 -x +1/4) + 2
y = -2 (x - 1/2)^2 + 7/4

Therefore, the vertex is (-1/2, -7/4)

at x = 6, y = -58

A neuron's sodium channels are malfunctioning and will no longer open. How would this prevent the cell from changing its polarity, and why?

Answers

The cell will not be able to depolarize due to unavailability of sodium ions.

What is the role of sodium gates in action potential?

  • Sodium voltage-gated channels can be either closed, open, or inactive.
  • Voltage-gated sodium channels are closed when at rest. Both an activation gate and an inactivation gate are present in voltage-gated sodium channels.
  • Although the inactivation gate is open, the activation gate is closed. This conformation is closed but capable of opening. Some of the activation gates open as a result of membrane depolarization brought on by a stimulus.
  • Both the activation and inactivation gates will be opened at this point. As sodium ions enter the cells, nearby activation gates will open.
  • A greater amount of sodium will enter the cells as a result, initiating an action potential.
  • Both gates open when certain depolarization thresholds are reached. Action potential increases to its maximum as sodium rushes into the cell.
  • The inactivation gate will gradually close and the permeability of the membrane to sodium ions will decrease. The channel is now in a state known as "closed but not capable of opening."

#SPJ2

Answer:

it could not depolarize because the cell cannot become more positively charged.

Explanation:

When sodium gates open, depolarization occurs, changes the charge of the ion from negative to positive. Therefore, if the sodium channels no longer open, the flow of sodium into the cell that changes the charge from - to + and depolarization would not occur.

Gram-negative bacteria have a cell wall that is and does not accept the stain, making it appear .

Answers

Gram-negative bacteria have a cell wall that is thin and does not accept the stain, making it appear red or pink.

Gram staining is used for differentiation gram-positive from gram-negative bacteria based on the characteristic of their cell wall. Gram-negative bacteria have a thinner cell wall than gram-positive bacteria. In this staining, bacteria are first stained with crystal violet dye. Only gram-positive bacteria will be violet colored because they can retain the dye thanks to their cell wall. The second staining with fuchsine or safranin will give the red or pink color to the gram-negative bacteria.
