The hominid that is described is <em>Australopithecus africanus</em>.
<em>Australopithecus africanus</em> is one of the extinct hominids. It lived approximately from between 3.2 to 2.1 million years ago, in the late Pliocene and early Pleistocene. It is a species that lived in Africa, but its total range is not well known as there is only four fossils from it found, all in the same region, in the southern part of Africa.
The <em>Australopithecus africanus</em> is thought to be the ancestor of the later <em>Homo habilis</em>, and it is also considered to be a direct ancestor of the modern <em>Homo</em> <em>sapiens</em>, though that is still debatable.
Answer:
a. increasing birth rate with a greater number of young organisms
Explanation:
When the population growth is increasing in an area there is an increasing birth rate and the age structure begins to young.
Population growth is the increasing trend in population parameters that ensures that more organisms are produced.
The birth rate is the chief factor that populates an area.
When birth rate increases, new and younger organisms are produced and this tips the population towards a very young age.
An ageing population is one where the birth rate is quite low.
Answer: The correct answer is-
D.the genes of its chromosomes.
Inherited traits are the characteristics of an organism that are transferred from parents to their next generation through genetic material (DNA).
For Example- Eye color, hair color, skin tone.
Gene corresponds to the unit of heredity that can be described as the segment of DNA that codes for a particular protein. They are present on the chromosome (thredlike structures composed of DNA).
The protein that is formed by gene, depicts a specific trait of the organism.
Thus, inherited trait of an organism are determined by the genes, located on the chromosome.
