4m/s²
Explanation:
Given parameters:
Velocity of the ride = 6m/s
radius of the ride = 9m
Unknown:
Acceleration of ride = ?
Solution:
We are going to solve this problem using the formula for centripetal acceleration:
Centripetal acceleration = ![\frac{[tex]V^{2}](https://tex.z-dn.net/?f=%5Cfrac%7B%5Btex%5DV%5E%7B2%7D)
}{
}[/tex]
V is the velocity
r is the radius
Centripetal acceleration = 
= 4m/s²

Answer:
B. To provide energy for the bass and snapper turtles
Answer and Explanation:
To determine the overall health of the alligator pond, Mr. Ortiz should carry out the following tests:
pH is extremely important in this type of research as a reduction of pH could lead to a higher availability of toxic metals that may be absorbed by aquatic organisms such as alligators and fish species.
<em>pH is acceptable in a range of 6.5 to 8.2.</em>
- <u>Nitrates and Ammonia (NH3) levels</u>
Oversaturation of nitrates and ammonia could lead to the death of organisms that are crucial for the maintainance of a healthy pond and for the balance of the food chain.
Moreover, it could lead to algal blooms that result in a lower concentration of oxygen available for other organisms.
<em>Over 0.2 per L could be lethal</em> to some fish species that are also important for the health of the alligator pond.
<em>Less than 0.1 </em>indicates a healthy alligator pond.
- <u>Bacterial coliform test</u>
This test determines the amount of bacteria that comes from waste (animal or human), which could lead to mild to serious bacterial infections and diseases.
If it is a healthy pond, the results should indicate <em>less than 10 fecal coliform bacteria/100 mL.</em>
The answer seems like water. We're made up of 70% of water & many of the chemical reactions necessary for live need water as a reactant or a solvent.
Hope that helps!
Answer:
Stomata - specialized cells that contract and expand to open or close pores for gas exchange. Stomata can adjust to temperature, staying closed when temperatures are hot and dry to prevent gas and water loss.
Explanation:
Stomata (singular stoma) are pores found in the epidermis of plant leaves. Stomata open and close in response to the change in structure of two guard cells either side of the pore opening. When the guard cells are turgid, the stomata open, when they are flaccid, they are closed.
This functions to permit gas exchange while preventing the loss of water, especially during hot, dry weather. The stomata can only open when the guard cells are turgid, pulling the stomata apart.
