Can you identify the key changes that occurred during hominid evolution?
2.7 mya Neanderthal lives in woods and grasslands, has massive jaws for chewing on roots and vegetation.
2.5 mya Hominids start to use stone tools regularly, develop a brain 850 cm'.
Between 4-6 mya ape-hominin transitional species adopted bipedalism.

1.8 mya Homo erectus is found in Asia. First true hunter-gatherer ancestor, first to migrate out of Africa in
large numbers and attains a brain size of around 1000 cm
Australopithecus had a combination of humanlike and apelike traits: they were bipedal but had small
brains.
Homo habilis appears to be intermediate in terms of evolutionary development between the primitive
Australopithecus and the more advanced Homo species.
1.5 mya Homo Heidelbergensis lives in Africa and Europe. Similar brain capacity to modern humans.

the relative atomic mass of an element is the mass of one atom of that element, relative to 1/12th of the mass of a  1212c atom. to convert to an absolute mass in kg, it is necessary to multiply by  1.661×10−271.661×10−27.

the relative atomic mass is roughly equal to the number of neutrons, plus the number of protons, in the nucleus of the atom.

for elements with more than one stable isotope (different types of nucleus with different numbers of neutrons but the same number of protons), the quoted mass is usually the average mass, weighted by the relative abundance of the different isotopes.

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

well the answer is 2!

the answer is c. altitude. hope this ! #brainiac
