An investigator can collect hairs they observe visually (with tweezers or by hand), and they can also use clear tape to lift non-visible hair from a variety of surfaces, such as clothing. Other methods of hair sample collection include combing and clipping methods.
I really hope this helps I’ve been there too and I’m just doing this so I get the 20 words and I have the picture
In the given question according to the information the process of polymerization is an addition polymerization.
<h3>What is polymerization?</h3>
Polymerization is a process in which addition of many small molecules takes place for the formation of a large three dimensional substance known as polymer.
In the polymerization of polyethene the small repeating molecule is ethene and in this process product formed due to the addition process to the double bond of the ethene.
- In condensation polymerisation removal of water molecule or any other molecule takes place.
- In dehydrogenation polymerisation removal of hydrogen molecule takes place.
- In dehydrohalogenation polymerisation removal of hydrogen halide molecule takes place.
Hence given process is an addition polymerisation.

Respuesta:
340 N/cm²
Explicación:
Paso 1: Información provista
Peso de la estructura (F): 8500 Newton
Area superficial (A): 25 cm²
Paso 2: Calcular la presión (P) ejercida por la estructura de concreto sobre su base
La presión es igual al cociente entre la fuerza ejercida y la superficie sobre la que se aplica.
P = F/A
P = 8500 N / 25 cm² = 340 N/cm²
Answer:
because it will control the birth of a child which can happen alot being overpopulated in the country or world. It also can mange their life and create a small and happy and healthy family.Also the child can get more love and support from their parents if they have less children and it wont be a taruma for the couple as well. because growing a child can be expensive time costly and really hard.
