Answer:
C
Explanation:
This is what is referred to as peer-reviewing. To gain veracity for her results, the fellow scientist replicates the experiment under the same parameters that she did and determines if the same results are achieved, If so, the results and experiment gain veracity and can be quoted on other scientific journals. For the experiment to be replicated, it needs to be clearly defined in the report, a requirement for all scientific reports.
<span>The cells all have different qualities.
A plant cell will have a cell wall (the others don't have these) and so it will be kept in a rigid shape, unlike the others which are free to be blobby. Inside a plant cell, there is also a vacuole containing cell sap. The others don't have this. Plant cells also have chloroplasts, which look similar to mitochondria on a diagram. Chloroplasts contain chlorophyll, and this is used for photosynthesis. </span><span>

The number of covalent bonds that an atom tends to form is equal to the number of valence electrons.
Explanation:
Covalent bonds are formed between non-metals by sharing of the equal number of valence electrons between the two atoms. The valence electrons are the number of electrons in the outermost shell of the atom. These valence electrons share between the atoms and from bonds. eg. are NH3 and H2.
The sharing of valence electrons complete the octet rule and covalent bonds are formed.
