Metallic Bonding is restricted to metals only. In the metallic bonding, There is a electrostatic force of atrraction between the metal ions (which are positive)
and the electrons(which are negative).
The metal ions are arranged in a lattice pattern which is the regular repetitive structure.
_____________________________________Electron Sea Level:Every metal atom donate one or two valence electrons, so due to the BULK presence of the electrons, It results in a formation of sea of electrons. So the valence electrons don't just stay on their own atom, they roam around the whole metal. They are just like a sea of electrons. This is why it is called the electron sea model. basically metal ions are present as a iceberg or island in the freely floating sea of electrons.
_____________________________________How is Sea of electron related to the malleable and ductile property?The sea of electron works as a electron GLUE, That means the metal ions are strongly ATTRACTED to the electron, so When apply pressure on the metals they DONT BREAK that means they are not brittle but malleable and ductile. This is because of the moving electrons and because the cations slide easily past each other, The ability of the atoms to roll over each other into new positions without breaking the metallic bond is because of the electron glue.
_____________________________________IMPORTANT STATEMENTSBrittle; Hard but breakable due to absence of sea of electron.
Malleable and Ductile; Transformed into sheets and thin wires so they are somewhat ELASTIC.

Explanation:
if your poop is green, is that a good thing or a bad thing.
Answer:
All shades of brown and even green are considered normal. Only rarely does stool color indicate a potentially serious intestinal condition. Stool color is generally influenced by what you eat as well as by the amount of bile — a yellow-green fluid that digests fats — in your stool.
Answer:
You will be fine I hope. :) It just says you have been eating green foods.
Explanation:
What organelle(s) gives plant cells their shape?
O A chloroplasts
O Blarge central water vacual
O C cell wall
O D both B and C contribute to the plant cells shape.
Answer:
A. Chloroplasts
Explanation:
Plant cells have a cell wall, chloroplasts and other specialized plastids, and a large central vacuole, which are not found within animal cells. The cell wall is a rigid covering that protects the cell, provides structural support, and gives shape to the cell.
Hope this helped. Have a Great Day!!!
Answer:
options 1 chloroplasts is the correct answer
The structures responsible for completing the breakdown of carbohydrates into usable energy for the cell are the
A. Nuclei
B. Mitochondria
C. Ribosomes
D.chloroplasts
Answer:
The correct option is;
B. Mitochondria
Explanation:
The mitochondria are the organelle of the cell bund to the membrane that are referred to as the cell powerhouse they function in the same manner as the digestive system, such that they take in raw nutrients which are broken down to produce energy containing molecules which makes up the majority of the chemical energy required for the various biochemical reactions of the cell in a way such that the energy they produce are stored in adenosine triphosphate (ATP) molecules.
Answer:
B. Mitochondria
Explanation:
The mitochondria are cellular organelles found in eukaryotic cells. They are structures involved in cellular respiration, which is the process whereby energy in form of ATP is synthesized for use by the cell.
Cellular respiration in eukaryotes occurs in stages including glycolysis, kreb's cycle and oxidative phosphorylation. All these processes combine to breakdown carbohydrates (glucose) into usable energy for the cell. The structures responsible for this process is MITOCHONDRIA.
What is true about autotrophs, but no heterotrophs?
Answer:
They use sunlight, water, and carbon dioxide to make sugars.
Explanation:
The process of photosynthesis is energy-storing because the process converts light energy into chemical energy, which is stored in the bonds of glucose.

how steroids affect skeletal system and muscular system.
(5 sentences for each system)
Answer: Many drugs can affect muscular control and skeletal strength. Steroid use during childhood or adolescence, resulting in artificially high sex hormone levels, can signal the bones to stop growing earlier than they normally would, leading to short stature. PCP can cause a user to have severe muscle contractions.

4. Which statement describes an exception to the cell
theory?
A) Plants and animals are made up of structural
units known as cells.
B) Mitochondria and chloroplasts contain genetic
material and can replicate.
C) All cells arise from preexisting cells.
D) The cell is the basic functional unit of all living
things.
The statement describes an exception to the cell theory - B) Mitochondria and chloroplasts contain genetic material and can replicate.
The cell theory is the theory that is given by German researchers Theodor Schwann, Matthias Schleiden, and Rudolph Virchow. This theory states three major principles:
All living organisms are composed of one or more cells.The cell is the basic unit of structure and organization in organisms.Cells arise from pre-existing cells which means cells divide and pass on hereditary informationenergy flows within cells.Thus, the statement describes an exception to the cell theory - B) Mitochondria and chloroplasts contain genetic material and can replicate.

phenotype and genotype of this punnet square?
Answer:
Phenotype: whatever the capital P is
PP and Pp
Explanation:
So the genotype is PP 1/2 Pp 1/2
and so in your question it should have whatever the "PP" and "Pp" stand for in your question would be it. So lets say red flower = PP and Yellow flower = Pp so it would be Red Flower 1/2 and Yellow Flower 1/2
