Answer;
-Elements, that are metallic (metals)
Experiment;
Metallic minerals contain metal in raw form.Metallic minerals occur in rare, naturally formed concentrations known as mineral deposits.These minerals contain metallic bonds.
Metallic bonding result from atomic nuclei and inner filed electron shells in a sea of electrons made up of unbound valence electrons or not equally shared
Metallic bonding yield minerals that are soft, ductile / malleable, highly conductive due to easily mobile electrons - metals, also non-directional bonding produces high crystal symmetry
About Phospholipid:
Cells are surrounded by a very important type of lipid called phospholipid. Phospholipid consists of hydrophilic (water loving) head and hydrophobic ( water fearing) tail. Phospholipid like to line up and arrange themselves into two parallel layers called phospholipid bilayer.
Importance of phospholipid:
Forms bilayer which provides barrier around the cell and only let in certain molecules like carbondioxide and oxygen necessary for cellular respiration.
During digestive process phospholipid form clusters to help move vitamins, nutrients and fat containing molecules through the body.
They can be used as signal transducer between cells.
They split to form product called second messenger, that can signal for leukocyte to migrate to the site of infection.
Phospholipid that is both structural and functional is sphingomyelin, forms the insulation that protect your nerves and facilitates the conduction of nerve impulses.
Phospholipid in stomach helps in breaking down the fat.
Phospholipid in bile help emulsify fats so they can be carried in blood.
<span>Scientific research has an integral relationship to environmental resources. Resources that exist in the environment can help scientific research by making available the material that is necessary to conduct experiments. Water is an environmental resource and scientists can test the water in the environment in order to see if there are toxic levels of chemicals in the water. Without these resources, the science would not be as relevant.</span>
