A bacterial cell measures 2.5 micrometers (µm) in length. What is the size of this cell in nanometers (nm)?

250 nm

Explanation:

Data provided in the question:

Length of the bacteria cell = 2.5 micrometers (µm)

Now,

We know that,

1 m = 10⁶ µm

or

1 µm = 10⁻⁶ m

also,

1 m = 10⁹ nm

or

10⁻⁹ m = 1 nm

Therefore according to the above results we get,

2.5 micrometers (µm) = 2.5 × 10⁻⁶ m

and,

2.5 × 10⁻⁶ m = ( 2.5 × 10⁻⁶ ) × 10⁹ nm

= 2.5 × 10³

= 250 nm

the correct answer is 4) heat and pressure

metamorphic rocks arise from transformation of existing rocks types, in a process called metamorphism. during metamorphism the original rock(prolith) change into metamorphic rock by heating (150-200c) and pressure of more than 1000 bar. the original rock can be sedimentary, igneous, or existing metamorphic rock.

the answer is z.

the human body has five levels of organization. level 1: cells. cells are the basic units of life and form the first level of organization. cells in the human body have specific functions. examples include nerve cells, blood cells, liver cells, and so on.
