Answer;
-Change in pressure.
Explanation;
-Increasing the pressure on a reaction involving reacting gases increases the rate of reaction. If you increase the pressure of a gas, you squeeze it into a smaller volume.
-When you increase the pressure, the molecules have less space in which they can move. That greater density of molecules increases the number of collisions. When you decrease the pressure, molecules don't hit each other as often and the rate of reaction decreases. Pressure is also related to concentration and volume.
Answer:
4C/hr
Explanation:
68-52=16 gives us the temp change, so you divide it by 4 hours for the temp increase each hour 16/4=4
Answer: As scientists started improving on the microscopes, the more they got to observe the cells in depth. Compound light microscope uses visible light to produce a magnified image and doesn't allow it to scatter.
Glassy, because of the crystals being clear and shiny and fast cooling
Answer:
The correct answer is ''gravity.''
Explanation:
Tropisms are movements or changes in posture that a living being normally makes in response to a continuous environmental stimulus. Plants have hormones that respond to the gravitational impulse of our planet. Gravity deeply influences their growth and development (positive geotropism) and plants have been found to bend in response to gravity due to redistribution of the plant hormone auxin at the root tip, so that auxin is redistributed to the underside of a root that grows when it is rotated 90 degrees, the stems will still grow upward, away from the center of the Earth (negative geotropism), just as roots will always grow in the reverse direction (positive geotropism).
