You are reading a blog written by a student who is working at an archeological dig in cyprus. she mentions that they just uncovered an ancient burial site in which the skeletal remains of a human are found next to those of a cat. the arrangement of the bones suggests that the cat was buried with its owner and may have been a pet. remarkably, the location of the grave relative to other known artifacts suggests it is 10,000 years old. if this is correct, then this is the earliest evidence for cat domestication. the blog author suggests that dendrochronological analysis of some of the wood fragments found nearby, together with c14 analysis should confirm the dates. you are not so sure these two methods will work equally well. which method is most likely to shed accurate insight into the age of these two skeletons? why?

Obviously C-14 Method...

Explanation:

First things to clear first that the dendrochronological analysis is used only for plants that are alive. the second thing to under stand is that this analysis of a wood fragment would only give ages according to the size and number of rings present in the bark of wood.

The C-14 is a highly effective way because it can give aging analysis even for a million years or so and scientists used it everyday to predict the age by analyzing decayed organic carbon isotope C-14 present in every life form dead or alive on Earth.

water is a polar molecule. a chemical bond is a force of attraction between atoms or ions. bonds form when atoms share or transfer valence electrons. atoms form chemical bonds to achieve a full outer energy level, which is the most stable arrangement of electrons. so, false

explanation:

in h2o molecule, two water molecules are bonded by a hydrogen bond but the bond between two h - o bonds within a water molecule are covalent. the greater the electronegativity difference, the more ionic the bond is. bonds that are partly ionic are called polar covalent bonds. nonpolar covalent bonds, with equal sharing of the bond electrons, arise when the electronegativities of the two atoms are equal.

label a cell membrane

label b cytoplasm

label c ribosomes

label d dna

the membrane forms the outside of the cell

cytoplasm is the liquid within

ribosomes are the components within that distribute rna

the dna is the genetic make-up
