Answer:
The correct answer is option (d)-"All of these are found in the fossil record and have been used by scientists to understand human evolution".
Explanation:
There is plenty of evidence that supports the proposal of how humans has evolved during past times. The fossil records that scientists has used understand human evolutionary patterns include the following. Ardipithecus ramidus bones that revealed advances in upright walking, even tough they had a small brain that measured between 300 and 350 cm3. Australopithecus lack of an opposable big toe suggest that they lived on the ground instead of in trees. Homo erectus was the first species to use and control fire, as suggested by evidence of microscopic traces of wood ash.
a,b,c and d
Explanation:
Most prokaryotes have capsule but most eukaryotes lack capsule
Eukaryotes are generally larger than prokaryotes
The ribosomes of prokaryotes are smaller than that of eukaryotes
Generally, prokaryotes have pili but pili is absent in eukaryotes
The changes only are passed down when they are in the gametes. So the answer is <span>sex cell</span>

Single-celled organisms exchange gases directly across their cell membrane. However, the slow diffusion rate of oxygen relative to carbon dioxide limits the size of single-celled organisms. Simple animals that lack specialized exchange surfaces have flattened, tubular, or thin shaped body plans, which are the most efficient for gas exchange. However, these simple animals are rather small in size.
