Biofilms preferentially form in moists environments with high levels of
nutrients.
<h3>What are Biofilms?</h3>
These comprises of one or more types of microorganisms which grow on
different types of surfaces.
The surface which favors the growth of these microbes are usually very
moist with high nutrients which they feed on for their growth and survival.

Explanation:
<h3>The antiparallel arrangement of the two strands is what causes the twist. Because the strands run in opposite directions, they pull the sides of the molecule in opposite directions, causing the whole thing to twist around itself. Most naturally occurring DNA spirals clockwise.</h3>
20 chromosomes.
A cell with 40 chromosomes going through meiosis will result in individual haploid cells with 20 chromosomes each.
After the first nuclear and cellular division in meiosis, each cell will already have 20 chromosomes each, since homologous chromosomes are separated at Anaphase I in Meiosis I. After the second nuclear and cellular division in meiosis, each cell will have 20 chromosomes as well, since the sister chromatids of each of the 20 chromosomes are separated during Anaphase II in Meiosis II.
Hope this helps! :)
Crops need nutrients just like people do. A fertile soil will contain all the major nutrients for basic plant nutrition (e.g., nitrogen, phosphorus, and potassium), as well as other nutrients needed in smaller quantities (e.g., calcium, magnesium, sulfur, iron, zinc, copper, boron, molybdenum, nickel). Usually a fertile soil will also have some organic matter that improves soil structure, soil moisture retention, and also nutrient retention, and a pH between 6 and 7. Unfortunately, many soils do not have adequate levels of all the necessary plant nutrients, or conditions in the soil are unfavorable for plant uptake of certain nutrients.
