Answer:
ways it rust are
1.you put water on it
2.let it sit out side for about a month or 2
or
you put the iron in water still wait a month or 2 then
you got the full or sum rusty parts
Explanation:
ether way you need water, air ,and the main thing... IRON

Answer:
Among the different types of scientific knowledge hypotheses are likely to be modified or discarded most frequently. Long ago in the 1600's scientists discarded the phlogiston theory because the new evidence didnt support it.
Explanation:
Hypothesis is the assumption of something possible or impossible to draw a consequence and is provisionally established as the basis for an investigation and which can confirm or deny its validity. For this reason, within scientific research, hypotheses are so important and so changeable that they are modified or discarded more frequently within scientific knowledge.
Based on a work by Johann Joachim Becher, the German scientist Georg Ernst Stahl created the phlogiston theory that said combustion occurred with certain materials because they had an “element” or a common flammable principle that was released at the time of burning . This theory was abandoned because there was no evidence, even through scientific experiments, to prove that this theory is true.
Hypotheses are likely to be modified or discarded most frequently in scientific knowledge. Phlogiston theory was discarded due to evidence contradicting its predictions.
Among the different types of scientific knowledge, hypotheses are likely to be modified or discarded most frequently. Long ago, in the 1600s, scientists discarded the phlogiston theory because evidence contradicted the predictions made by the theory. Phlogiston theory proposed that a substance called phlogiston was released during combustion, but experiments showed that substances gained weight instead of losing weight during combustion.

One example would be the dissolving of molecules with water so that they can be transported.
the cell theory states that all new cells come from other living cells, and it's true for both multicellular as well as unicellular organisms.unicellular organisms reproduce through asexual reproduction,There are different types of reproduction like binary fission, vegetative, budding, fragmentation etc reproduction in unicellular organisms, through that they directly divide into new similar cells.
whiltin multicellular organisms, reproduction takes place through sexual reproduction, where male and female gametes are formed in separate reproductive organs and get transferred to form an embryo.
so in nut cell in unicellular organisms there is no specific organs,that is responsible for reproduction, while in multicellular there coplex reproductive system
Answer:
D. chemical bonding
Explanation:
Atoms are joined to form compounds by ionic bonds (formed when one or more electrons are transferred from one atom to another) or covalent bonds (formed when atoms share electrons instead of transferring them). The ionic bonds and covalent bonds are both different types of chemical bonds.
Given statement that a single replacement reaction is reaction in which one element replaces similar element within compound is true as in these reactions similar element displaces other element from it's compound.
An element is defined as a substance which cannot be broken down further into any other substance. Each element is made up of its own type of atom. Due to this reason all elements are different from one another.
Elements can be classified as metals and non-metals. Metals are shiny and conduct electricity and are all solids at room temperature except mercury. Non-metals do not conduct electricity and are mostly gases at room temperature except carbon and sulfur.
The number of protons in the nucleus is the defining property of an element and is related to the atomic number.All atoms with same atomic number are atoms of same element.
