As liquid water freezes, the molecules arrange themselves in a way that takes up more space than liquid water. what would most likely occur if the arrangement of frozen water molecules required less space than that of liquid water molecules?

a).the density of ice would be greater than the density of liquid water, and ice would not float.

b). ice would form in layers, and liquid water would get trapped in between the layers.
liquid water would have a higher specific heat, making it less likely to undergo vaporization.

c).the freezing point of water would decrease, making ice more difficult to form.

The construction of phylogenetic trees is a mapping out the proposed divisions and common ancestors of all living species. traditionally, these trees have been built using morphological data, such as appearance and embryology. recently, it has been possible to construct these trees using molecular data. phylogenetic trees based on different types of information agree with each: that there is strong evidence of a real underlying common descent. this phylogenic tree is composed based on molecular data (rrna). what statements can we infer are true about the organisms throughout the tree? because the tree is rooted, all branches share a common ancestor. all organisms have some sort of cellular structure/organization. all eukaryotes evolved from bacteria. since the organisms contain rna, they share the same dna. if the organisms contain rna, the share the same four nitrogen bases.

The ruiz family is exchanging euros for us dollars. the exchange rate is 1 euro equals 1.35261 usd. since the ruiz family knows that usd are stated to the nearest hundredth of a dollar, they used the conversion ratio

How do the evolutionary chart and the video support the claim that all living things are made up of cells?
