Biology
1 answer:
Alla [95]3 years ago
8 0

Answer:

D

Explanation:

The correct option would be D.

12 - 2 would give +10

-5 + 5 would give 0

-5(-2) would give +10

24 - 34 would give -10

Hence, options A, B, and C are incorrect because they give figures that deviate away from -10. <u>The only option whose operation results to -10 is D.</u>

Why do hevier objects fall more slowly than lighter objects
Delicious77 [7]

Actually, heavier objects fall faster. The difference is infinitesimal, but there is a tiny difference because more mass causes objects to fall faster (e.g. objects fall faster on earth than on the moon). On earth, the different rate of fall between heavier and lighter objects is negligible (because objects are tiny compared to the earth's mass), so objects of different weights fall at virtually the same rate. But not at exactly the same rate. Objects of different weights must accelerate at different rates because accel.

The two graphs shown below represent data collected from the same lake
Natali [406]

Answer:

C. The trout population decreases as oxygen levels decrease.

Explanation:

We can see that the relationship between the number of trout and time passed is decreasing from the graph on the right because its line is decreasing. From the graph on the left, we can see that oxygen is decreasing as time goes on. Thus, we can interpret that the trout population decreases as oxygen levels also decrease; a proportional relationship.

The other options are incorrect because we can actually see that for...

A; the population of whitefish actually decreases as oxygen levels also decrease.

B; the population of carp actually increases significantly as sewage levels increase.

D; the walleye population actually also decreases overall as sewage levels increase.

What part of the brain is being tested when a police officer asks a DWI suspect to walk a straight line and touch his nose with
Illusion [34]
The part of the brain that is being <span>tested when a police officer asks a DWI suspect to walk a straight line and touch his nose with his finger is the primary motor cortex.
The motor cortex has to do with movement and balance - so obviously, if you need to prove that you can walk a straight line, which involves both of these things, or if you need to move your finger to a certain spot, which also involves both balance and movement, that would be the correct answer.
