Apencil measures 18 cm long. how many millimeters long is the pencil?

180 mm

Explanation:

We are given that a pencil whose measure 18 cm long .

We have to find that length of pencil in millimeter

In order to find the value of length of pencil in millimeter we are using conversion of centimeter into millimeter  by the unitary method

We know that

1 cm =10 mm

Multiply 10 by 18

18 cm =

After multiplying we get

18 cm =180 mm

Length of pencil in  millimeter is 180 mm.

Hence, the pencil is 180 mm  long.

step 1 ammonium can be absorbed by plants, but some is converted into nitrates which are better for plants to absorb. this is called nitrification. 2. step 2 the deer eats the plants and uses the nitrogen-containing proteins for cell growth. 3. step 3 bacteria in the soil conduct nitrogen fixation to convert nitrogen gas from the atmosphere into ammonium. 4. step 4 some of the nitrates are absorbed back into plants, but denitrification breaks down the nitrates into nitrogen gas released back into the atmosphere. 5. step 5 nitrogen is found in the urine, which gets broken down into ammonium through the process of ammonification. 6. step 6 plants absorb the ammonium and begin assimilation, the process to add the nitrogen to protein.

archaebacteria are found in in forest soil.

hope i spelled it right lol
