The lineage that produced chimpanzees and humans split from other primates roughly 30 million years ago. Chimpanzees' skulls have the following features: Trait A, found in fossils as old as 10 to 12 million years, is molars with thick enamel. Trait B, found in fossils as old as 55 million years, is a postorbital wall that ventrally separates the orbit from the temporal fossa. Which of the following statements is TRUE? a. Trait A is more beneficial for chimpanzee survival because it is newer.
b. Trait B is more beneficial for chimpanzee survival because it is older.
c. Trait Ais more likely to be widespread among other primate species because it is newer.
d. Tralt is more likely to bo widespread among other primato species because it is older.

The answer is D

Explanation:

The statement is telling us about the moment when the lineage of chimpanzees and humans separated from other primates, it is not telling us which trait or characteristic is superior.

Of the options given, the one that comes closest to the logic and coherence of the statement is option D, since it confirms the statement that possibly until 55 million years ago the lineage that produced chimpanzees and humans had not yet been separated from others primate lineages.

answer: zinc is the substance which has a volume of 1.38 .

density is defined as the mass of an object per unit volume.

it can be calculated by dividing mass of a substance by its volume i.e.

si unit of density is kg per cubic meter and cgs unit of the same is gram per cubic centimeter.

now from the given data volume can be calculated by the formula .

hence, the volume of aluminium will be = which comes out to be 1.703 .

similarly, volume of zinc, chromium, and nickel will be 1.378 , 0.869 , and 0.356 respectively.
