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).
Answer:Phosphorylation cascades are similar to a row of dominoes falling down, instead of one domino knocking down the next, a phosphate being added activates the message. In this way, a series of different _(phosphate group) are each _(added ) after another. Inactive protein kinase 1 gets a __(phosphate group_)___ added and now it is active protein kinase 1. Active protein kinase 1 transfers a (phosphate group) and now inactive protein kinase 2 is now ___(active)_____. This continues until the desired (protein ) is activated to cause a cellular response.
Explanation:
Answer:
pressure
Explanation:
the earth's tectonic plates create pressure to make the magma rise
It is because leaves are the main users of photosynthesis in a plant. The sunlight seeps into the leaves, and the leaves transform the sunlight's energy into sugar; their food.
