The fossils from
Australopithecus provide evidence for evolution because some parts of the bone
that contains the DNA of it can be identified as this type of animal. They can
be detected through the use of carbon dating devices.

Answer:
a. Trisomic
Explanation:
A trisomy is a genomic phenomenon whereby a particular chromosome is present in three copies. In this case, the trisomy involves the chromosome P, being this species a tetraploid with 5 pairs of homologous chromosomes (2n = 10). In humans, the trisomy for chromosome 21 is one of the most common types of aneuploidies that lead to the Down syndrome by producing alterations in gene expression patterns that are associated with changes in the phenotype
The question is incomplete as it does not have the options which are:
A) chordate.
B) echinoderm.
C) nematode.
D) mollusc.
Answer:
A) chordate.
Explanation:
The animals can be distinguished based on embryonic development and are categorized into two types: Deutrostomes and the protostomes.
The deuterostomes are the organism in which the small opening in the embryo called the blastopore develops into the anus. The deuterostomes organism belongs to two groups of the animal: the echinoderms and the chordates.
The chordates are the animals which possess the bilateral symmetry that is can be divided into left and right sides and posses true cavity or coelom.
Thus, Option-A is correct.
