Which of the following describes acceleration? A. Acceleration cannot be described with a negative number. B. Acceleration is a
Ainat [17]

The answer would be:

<u><em>B. Acceleration is a vector quantity.</em></u>

We can rule out the others because:

---Acceleration CAN be described with a negative number. The sign actually shows the direction. A negative number indicates a deceleration.

---Displacement change over time is the definition of velocity NOT acceleration.

---The SI unit for acceleration is m/s².

***A <em>vector quantity</em> is measure of <u>magnitude</u> and <u>direction</u>, which acceleration has.

Describe what happens as a plant's turgor pressure increases and decrease AS MUCH POINTS AS I CAN GIVE​
Dimas [21]

Answer:

Brainliest pls

Explanation:

Turgor pressure in plants. Turgor pressure within cells is regulated by osmosis and this also causes the cell wall to expand during growth. Along with size, rigidity of the cell is also caused by turgor pressure; a lower pressure results in a wilted cell or plant structure (i.e. leaf, stalk).

Turgor pressure in plants plays a key role in processes such as growth, development, mechanical support, signalling, flowering and stress response. Turgor pressure is an ideal means in plant cells through which the energy content of water molecules (water potential) can be adjusted quickly, within seconds.
