Answer:
c. Acclimatization
Explanation:
<u>Acclimatization</u> : Various physiological readjustments and compensatory mechanisms in body that reduces the effects of hypoxia in permanent residents at high altitude. These are basically the respiratory and hematopoetic adjustments to long-term move to high altitude.
As the Chum Salmon (oncorhynchus keta) are born in freshwater water constantly diffuses into the body and ions are lost from the body while in the sea water, they lose water.
As alot of changes are occrun in the cells of the gills of chum salmon, that is acclimatization as various physiological readjustments are being made.
The fossil record essentially keeps track of the abundance and appearance of various fossils during different time periods. As time goes on, the fossils change. Using the fossil record, we can compare and contrast the fossils to develop theories about changing life forms and their connection to time.
Hope this helped :)
Answer:
E. will have the same genes at the same locations
Explanation:
Homologous chromosomes are the pairs of chromosomes. The members of a homologous pair are genetically and morphologically similar to each other. One chromosome of a homologous pair is inherited from the father while the other one comes from the mother.
Genes have two or more alleles. The alleles of a gene occupy the corresponding position on the homologous chromosomes. These specific positions of alleles of a gene are called loci. Therefore, a particular locus is occupied by alleles of the same gene on two homologous chromosomes.
