Answer:
Temperature
Explanation:
catalyst have specify temperature range for their efficiency
Answer:
The changing variables are: v and KE
Explanation:
Given

Required: What changes?
From the formula above:



m: The mass of the skater is constant.
v: Moving up and down the track may change the velocity of the skater.
KE: When velocity changes, the kinetic energy also changes
So:
The changing variables are: v and KE
They check for mistakes and bias
Answer:
b. where movement occurs through arm-over-arm swinging.
Explanation:
Brachiation is a form of locomotion observed in some species of animal that are adapted to arboreal (tree living) life.
<em>This type of locomotion involves the swinging of arms and the suspension of the body to move from trees to trees.</em>
Animals that exhibit brachiation usually have modified body structure with long forelimbs/hook-like fingers and a highly mobile shoulder joints. Examples of such animals include gibbons and siamangs.
The correct option is b.
Layers of cross-bedded sand can be indicative of a DESERT environment wind is responsible for the formation of these sedimentary structures. Sand dunes preserved in rocks can be quite large. These structures form as a result of the migration of dunes due to the action of the wind. Dunes are not often preserved but a few can be observed in thick sandstone units.
