For the first time in five years California authorities have issued a first stage smog alert, warning people in some areas of unhealthy levels of ozone in the air. Smog contains several dangerous chemical compounds beside ozone: sulfur dioxide, nitrogen dioxide, and carbon monoxide. Since it would be impossible to wear gas masks like those in the picture, a reasonable plan would be to

Describe the typical movement of ciliates.

Answers

Paramecium: This large single-celled protist contains many, many short little "hair-like" structures called cillia, that cover the entire cell. The cillia move like little oars that help the paramecium swim and gather food into it's "food grove". The paramecium appears a light pink in color. Is known as a Ciliate.

during a 30 year period a severe drought occurred in three separate years according to this information what is the yearly frequency of drought?

Answers

During a 30 year period, the yearly frequency of drought is 10%, which is experienced in three separate years.
Additionally, drought is a period where precipitation is below average and thus resulting in prolonged shortages of water supply as far as both ground and surface water are concerned. This can last for several months or even for years.

Answer:

During a 30-year period, the yearly frequency of drought is 10%,

An example of a xerophyte would be _____. moss a cactus corn hornwort

Answers

Answer: cactus

A xerophytic plant is a species of plant that exhibit adaptations which allows them to survive in an environment where the atmosphere is dry and water availability is low. The regions where the xerophytic plants grow are deserts, ice or snow covered regions such as Artic or Alps.  

An example of a xerophyte would be cactus. Cactus are the xerophtic plants which dominate deserts as vegetation. These are leafless spiny plants, to prevent the loss of moisture by transpiration, the stems of these plants are called as succulent as they are adapted to store water.  

Answer:

a cactus

Explanation:

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.
