Answer: Option A (Density-independent factor)

Explanation:

Density-independent factor is a population regulation factor that affect or influence the size of a population without considering the population density. Climate and weather are the main density-independent factors in nature.

Their effects increment is directly proportional to the increase in population size. These factors are environmental agents that checkmate the size of a population without putting the reproductive and behavioral patterns of the organisms into consideration.

What kind of tissue provides plants with the first line of defense against damage and disease?
sergeinik [125]


The best answer - dermal tissue.

Dermal tissue in plants forms the first line of defense against physical damage and infection from the outside world.

Dermal tissue covers the outside of the plant, except in woody shrubs and trees, which have bark. The most common cell type in dermal tissue is epidermal cell. Generally, a thin waxy layer called a cuticle covers the epidermal cells and protects them.

Other cells in the dermal tissue are guard cells that surround the stomata, which are openings in the leaves. Gases enter and leave the dermal tissue through the stomata.

There are 1000 micrometres (um) in a millimetre (mm).
Vesna [10]

Answer: The length of the cell in millimetres is 0.0015.

Explanation:

Given conversion :

1000\mu m=1mm

Thus 1\mu m=\frac{1}{1000}mm=0.001mm

Given : Length of the cell = 1.5 micrometers (\mu m)

To find: Length of the cell in milllimeters (mm)

Length of the cell in milllimeters (mm) = 1.5\times 0.001mm=0.0015mm

The length of the cell in millimetres is 0.0015.
