The bad effect is that the pesticides could go into the air or other places that they shouldn't be. But this is a quicker way.

volatilization.- it occurs when a pesticide turns into a gas or vapor after it has been sprayed, allowing it to travel through the air and spread to different pieces of land.

Why is meiosis important for organisms? It allows for genetic variation among organisms. It determines which genes are dominant
Studentka2010 [4]

Meiosis is important for organisms since it allows for genetic variation among organisms.

<h2>Further Explanation</h2><h3>Cell division</h3>
  • Cell division is the process in which cells undergo division to form other new cells.
  • There are two types of cell division;
<h3>Mitosis Division  </h3>
  • Mitosis is a type of division in which a parent cell undergoes division to yield two daughter cells that are similar to the parent cells.
  • The daughter cells have equal number of chromosomes as the parent and are identical to the parent.
  • This type of cell division normally occurs in somatic cells of organisms and facilitates growth and development of organisms.
<h3>Meiosis division</h3>
  • Meiosis division is a type of division that occurs in gamete cells where a parent cell divides into four daughter cells that differ from the parent cells in terms of the number of chromosomes.
  • In meiosis the daughter cells have half the number of chromosomes as the parent cells.
  • Meiosis occurs in the gamete cells and facilitates sexual reproduction in living organisms.
  • Meiosis occurs in two phases, that is, meiosis I and meiosis II
  • During the process of meiosis several processes occurs that cause genetic variation among organisms.
  • These processes include, crossing over, independent assortment of genes, among others.
<h3>Crossing over  </h3>
  • Cross over is the process that occurs during the prophase I phase of the first stage of meiosis known as meiosis I.  
  • During the process of crossing over, genetic material is exchanged between homologous chromosomes which enhances the genetic variation in organisms.

Keywords: Cell division, meiosis, crossing over, genetic variation

For a species with a haploid number of 15 chromosomes, how many different combinations of maternal and paternal chromosomes are
babymother [125]
The answer is:  " 32,768 " .
___________________________________________
Explanation:
__________________________________________________________
 →  2ⁿ  = ? ;  {that is: "2" , raised to the "n th" power, equals {<u>what value</u>} ?
___________________________________________
 → Note that "n" is the haploid number, which is: 
                           "15" (value given within this very question).
__________________________________________________
→ So we plug in "15" for "n" ; to obtain the "final value" —
                                                          which is the answer.
__________________________________________________
           →  As such:  " 2¹⁵ = 32,768 " .  (using scientific calculator online).
___________________________________________________
           →  The answer is:  " 32,768 " .
