Answer:
Structural
Explanation:
Structural adaptations are a change to a organism's body, gills are part of the fish's body which would be why this is a structural adaptation!

Answer:
The measurement of the force it takes to work against gravity is called weight. You can measure weight on a scale. If you try to pick up heavy objects, you might need to be as strong as a super hero to lift them. Lifting overcomes the pull of gravity. Heavier objects need to have a strong force to lift them.
Explanation:
so I think it's D
Answer:
a)P(exactly 2 bulb from watt)= 0.11
b)P=0.097
c)P=0.233
d)P=0.235
Explanation:
Total bulb = 22
13 watt bulb = 8
18 watt = 9
23 watt = 5
We have to select 3 bulb out of 22 bulb
We know that probability is the ratio of favor condition to the total condtion.
The total number of way to select 3 bulb out of 22 =N
a)
P(exactly 2 bulb from watt)= 0.11
b)
The probability that all three of the bulbs have the same rating =P
P=0.097
c)
The probability that one bulb of each type is selected=P
P=0.233
d)
The probability that it is necessary to examine at least 6 bulbs =P
P=0.235
Answer:
False
Explanation:
According to Newton's 3rd law, the tension between the engine and the 1st freight cars would equals to the force required to pull all the freight cars from the 1st one on ward. In addition, Newton's 2nd law states that the F = ma, which means that force is proportional to the mass of all the freight cars, given that the freight train is accelerating. So if some of the cargo in the last car were transferred to other cars, their total mass would stay the same, and so as force F and tension.
