Skulls of
(1) modern gorilla,
(2) australopithecus afarensis,
(3) homo erectus,
(4) homo neanderthalensis,
(5) homo sapiens

based on the diagram, which of the following best describes ways in which the physical appearance of h. neandertalensis and h. sapiens differ?

a. h. neandertalensis had a heavier brow ridge and less pronounced chin than h. sapiens.
b. h. neandertalensis had a larger brain and smaller jaw than h. sapiens.
c. h. neandertalensis had lighter bones and less body bulk than h. sapiens.
d. h. neandertalensis had smaller teeth and a larger forehead than h. sapiens.

The correct answer is option A

All the people today are classified as the Homo sapiens. Human beings evolved many years ago in association with the  H. neandertalensis. Homo sapiens did not came after  H. neandertalensis but were their contemporaries.

Modern humans have delicate skeleton system. Their skull are more rounded and their brow ridge generally protude less as compared to that of  H. neandertalensis.

hydroxyl -oh

alcohols, always polar, can form hydrogen bonds with h2o molecules

carboxyl -cooh  

cargoxylic acids, has acidic properties which is a source of hydrogen ions, found in cells in ionized for with a charge of oh-1

carbonyl > co

ketone if within skeleton, aldehyde if group is at the end of skeleton, k & a may be structural isomers, it determines 2 sugars (ketose & aldose)

amino -nh2

amines, acts as a base, it can pick up h+ ions from surrounding solution, ionized with charge of 1+

methyl ch2

addition to rna/dna affects and gene expression

phosphate -opo3 ²⁻

organic phosphates, contributes to negative charge to, molecule that it is a part of, and potential to react with h20

sulfhydryl -sh

thiols, cross-linking stabilize the protein, and it is structure

step 1 ammonium can be absorbed by plants, but some is converted into nitrates which are better for plants to absorb. this is called nitrification. 2. step 2 the deer eats the plants and uses the nitrogen-containing proteins for cell growth. 3. step 3 bacteria in the soil conduct nitrogen fixation to convert nitrogen gas from the atmosphere into ammonium. 4. step 4 some of the nitrates are absorbed back into plants, but denitrification breaks down the nitrates into nitrogen gas released back into the atmosphere. 5. step 5 nitrogen is found in the urine, which gets broken down into ammonium through the process of ammonification. 6. step 6 plants absorb the ammonium and begin assimilation, the process to add the nitrogen to protein.
