Explanation / Answer

8 Organs

    Tissues are combined to form organs each and every organ is made of two or more tissues combined to together and organs combined together to form organ system .

9 DNA

The structure of DNA and sets of nucleotides that contain genetic information . Genetic information is stored within the chemical structure of the molecule DNA.

10 Limited by what can be investigated by scientific method.

    Evidence of any scientific question should be answered after proper scientific investigations and method and anything should be should be conclude only after thorough examination and results.

11. Community

    A community can be considered when there is interaction and living of organisms of various species under same environment in same location can be considered a biological community here the tree is inhabited by squirrel, robins, mushrooms and beetles at same location.

12. 22

Atomic number is the total number of protons present in the nucleus here in the element 22 protons are present hence the atomic number will be 22.

13 Chlorine is highly reactive than argon

Chlorine atoms have a lot of valance electrons without being complete and uncompleted shell is seen so it has need to seek other elections from valence shell . That's called Electro negativity. As it has greater electro negativity it is highly reactive

  14 Provide a basis of comparison to an experimental group.

    Having a control provides the baseline to compare the results of the main experiment to, so that the researcher can validate if it was the intervention responsible for the outcome or not

15 Hydrogen bonding between water molecules

Water's specific is a property caused by hydrogen bonding among water molecules. When heat is absorbed, hydrogen bonds are broken and water molecules can move freely. When the temperature of water decreases, the hydrogen bonds are formed and release a considerable amount of energy.
