Some plants increase in height due to changes in specialized regions of cells in the tips of their branches. The processes that
Nookie1986 [14]

Answer:

mitosis, cell growth, and differentiation

Explanation:

There are several ways through which plants grow which may include the process of mitosis mainly that involves cell division. The increase in height in plants is attributed to not only cell division but also growth of the newly formed cell.

Mitosis involved division of cell and in cell growth, cells increase their size that ultimately cause growth of plant height. The highly active growth cells are meristem cells that are found at tips of the plants. They are actively dividing zones of plants and with their division and growth plant increases their heights.

Another mechanism, responsible for increase in height is cell differentiation. Differentiation is the process during which cells are specialized to perform specialized function. For example: Xylem are specialized for transport of water. Phloem are specialized for the transport of food. Similarly, some cells are specialized for growth and they are aimed at increasing in size and division that ultimately increase the plant height.

So, mitosis, cell growth, and differentiation are the mechanisms, that increase plant height due to changes in specialized regions of cells in the tips of their branches.

Hope it helps!

Like rods, cone cells are depolarized when their opsin molecules are inactive. In the case of a cone, why might it be misleading
Olenka [21]

The most responsive of the three different types of cones to various light wavelengths. When light is present, a cone may become entirely depolarized if the sunlight is of a wavelength that is not optimal.

<h3>What do the eye's rods and cones do?</h3>

Rods are in charge of seeing in dimly lit environments (scotopic vision). They have poor spatial acuity and do not integrate color vision. Cones are responsible for color vision, high spatial acuity, and activity under higher light levels (photopic vision).

<h3>In the eye, how many rods are there?</h3>

The total number of rods inside the human retina (91 million) is significantly higher than the total number of cones, despite the fact human perception of average daytime ambient light is dominated by cone-mediated vision (roughly 4.5 million). As a result, over the majority of the retina, rod density is substantially higher than cone density.
