Answer:
A. fossils of archaic humans show we have evolved through the differences in bone structure. Humans used to look a lot like chimps, and through fossils we can see differences in our skull shape and size, differences in the amount of body hair we had, and through vestigial bones like wisdom teeth, which we do not need anymore today. Wisdom teeth were likely used to chew raw meat, which we do not do anymore.
C. Chimpanzees are our closest living relatives on the planet, with 99% of our DNA being the same.

Answer:
The correct answer is - transformation.
Explanation:
Griffith's experiment was performed by Fredrick Griffith with Streptococcus pneumoniae. Streptococcus P. are rough non encapsulated streptococci that are converted into smooth encapsulated streptococci bacteria in presence of heat-killed smooth encapsulated bacteria.
This experiment was the first experiment that showed that this bacteria can get DNA by the process of transformation.
He suggested that the nonencapsulated bacteria had been transformed into the encapsulated smooth bacteria strain by the transformation process that was somehow part of the dead encapsulated strain bacteria.
Thus, the correct answer - transformation.
Answer:
Chick with in the egg depend for all its energy and food requirement on the egg yolk , therefore egg yolk is rich in fat, protein, and cholesterol.
Explanation:
Before the egg breaks and the chick comes out, few days nourishment for chicks is required. Hence, the egg yolk needs to be nutritious as new developing chick (with in the egg) rely for essential nutrients (required for growth) on the egg yolk. Chick require energy from yolk, hence it is rich in fat (energy). It also needs to grow and develop, therefore egg yolk has lot of protein (building blocks). Lipid and cell with in the yolk help in formation of cell and strengthening of bones and feathers
