A covalent bond, also called a molecular bond, is a chemical bond that involves the sharing of electron pairs between atoms.
Sedimentary would be your answer. Sediment is the matter that settles to the bottom of a liquid, so as rocks, dirt and mud settled over the dead body it would fossilize inside the sedimentary rock.
Answer: A group of scientists wants to determine whether a relationship exists between alcohol consumption and certain types of cancer. To this end, scientists provide study participants with a questionnaire asking them how many alcoholic drinks they have per week and what diseases they have (if any). These scientists provide subjects with a similar questionnaire annually (for a decade). These scientists are performing an ASSOCIATION STUDY.
Explanation: Association study is observational study in different individuals to see if a particular behavioral pattern (such as alcohol consumption) can be associated with certain type of disease (such as cancer).
Information collected from the questionnaires distributed will be subjected to statistical analysis and conclusion(s) will be made.
B. the bond forms when electrons are shared
<u>Answer:</u>
<em>I belong to the kingdom Plantae.
</em>
<u>Explanation:</u>
<em>Plantae is one among the five kingdoms in the five kingdom classification. </em>Plants are not mobile organisms unlike organisms of other kingdoms. <em>The roots of plants hold them to the earth and thus they are immobile.
</em>
Being immobile, they cannot run away from potential dangers like mobile organisms. But being autotrophs they make their own food by the process of photosynthesis. <em>Heterotrophs depend on autotrophs for food to obtain energy. </em>
