It would be that the cornea is not curved enough, thus not allowing the pupil to expand to perceive further distances clearly. :)

Answer:

The correct answer is a cornea that is not curved sufficiently.

Explanation:

Hyperopia or farsightedness refers to a condition or state of vision in which far off objects are generally seen evidently, however, the close objects do not come into focus properly. The condition takes place in case if the cornea has too little curvature or if the eyeball is too short, thus, the light getting inside the eye does not get focused accurately.

Explain how a drought poses a threat to life and the biosphere. Use complete sentences.
Marina CMI [18]

Answer:

A drought poses a huge threat to all life. If a drought occurred the entire food chain would disintegrate within months. There would be no water for any animals or plants. Small mammals would not be able to eat plants, and reptiles would not be able to the small animals, and so on. A drought can destroy an ecosystem in a short amount of time.

Water is only being moved into the air through water vapor, so the air will become hotter than water. Land is also not moving in the atmosphere and absorbing heat like air is, so air will also be hotter than land, depending on what the land is made of.

Through precipitation, water in the atmosphere can return to the hydrosphere or percolate into the ground to become groundwater—part of the geosphere. ... Water in the biosphere can be released into the atmosphere through transpiration in plants, or respiration in animals.

Find the volume of a gold ring that has a mass of 12.00 grams. The density of gold is 19.30 g/mL. The volume is
kozerog [31]

Answer:

<h3>The answer is 0.622 mL</h3>

Explanation:

The volume of a substance when given the density and mass can be found by using the formula

volume =  \frac{mass}{density}  \\

From the question

mass = 12 g

density = 19.30 g/mL

We have

volume =  \frac{12}{19.30}  \\  = 0.62176165...

We have the final answer as

<h3>0.622 mL</h3>

Hope this helps you

Hey I need help with this element, compound, and mixtures worksheet
Alika [10]

We should describe a little bit the legend.

A - Element - we should have circles with same color and not bonded together (argon gas).

B - Compound - here we may have circles with same or different color bonded together (water or oxygen which is a diatomic molecule).

C - Mixture of elements - circles with different colors not not bonded together (mixture of noble gases).

D - Mixture of compounds - circles with same or different color bonded together but we should see two or more types of connectivity between circles (mixture of water and ethanol).

E - Mixture of elements and compounds - circles with same or different color bonded together mixed with circles with same color and not bonded together (a mixture between oxygen which is a diatomic molecule and noble gas like argon).

Now we may answer the question:

1) B

2) C

3) D

4) D

5) A

6) B

7) B

8) E
