False. Oxygen is absorbed in the alveoli sacs of the lungs.
Upon inhalation Air must first pass through the larynx and down to the trachea, which then splits off into two separate bronchial tubes, the bronchial tubes divide into smaller air passages known as the bronchi and those into even smaller bronchioles. The bronchioles end in tiny sacs called the alveoli which transfer the oxygen from the inhaled air to the bloodstream.
The answer would be to gain information about the current state of environment and ways to inprove it.
Answer:c).Random mate choice
d. )A large population e.) No new mutations
Explanation:The Hardy-Weinberg Principle predicts that in the large randomly mated population in the absence of migration,selection and mutation the gene frequencies remains the same. Hence, for the allele and genotype frequencies to remain constant there must be; a)random mated population b)large population c) No new mutation.
Answer:
Transposition to different chromosomes by the ancestral gene
Explanation:
Transposable Elements (TEs), also known as jumping genes, are genetic mobile elements which are able to move from one location to another on the genome. There are two major mechanisms of TE transposition: 1-cut-and-paste mechanism, where one particular TE is inserted into a new position on the genome without replication, and 2-copy-and-paste mechanism, where a new copy is generated and the original TE remains at the original genomic site. In this case, it is likely that new TE copies containing the ancestral (duplicated) gene have proliferated through the copy-and-paste mechanism.
