Which of the following statements about the ‘hobbits’ of flores is false?
select one:
a. all the answers are true
b. hobbits were alive at the same time as modern homo sapiens
c. the trapezoid bones (belonging to the hands) of hobbits are more similar to the trapezoid bones of chimpanzees than to the trapezoid bones of modern humans
d. ct scans of the fossilized skulls of hobbits suggest they were probably microcephalic modern homo sapiens

d. CT scans of the fossilized skulls of Hobbits suggest they were probably microcephalic modern Homo sapiens.

Explanation:

The work of Falk et al in 2007 compared the CT of microcephalic humans skulls and normal humans skulls, finding the variables that allow them to classified with 100% success. When compared with the skulls of the ‘Hobbits’ of Flores, the size is similar to the microcephalic skulls in humans but the shape features sort it with normal humans skulls. They concluded that the ‘Hobbits’ of Flores are a separate species.

what image you forgot to include it.

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.
