The
zebrafish lineage is the studied gene who evolved most rapidly as shown in its
branch where it manifest to have the longest lineages.<span> The changing branch lengths indicates
that the gene has evolved at different rates in each lineages and the branch length
is proportional to amount of the genetic variation in each linear.</span>
Energy
they could be producers or consumers
producers make their own food/energy
consumers get energy from other living things
Answer:<em> Living organisms must maintain a constant internal environment while living in a constantly changing external environment. </em>
Explanation: Maintaining the internal environment is important because the processes that keep the cell alive can only take place under certain conditions. There are different processes that occur in the body to maintain the constant internal environment such as diffusion, osmosis, homeostasis, active transport, passive transport, endocytosis, exocytosis, etc. Homeostasis helps to maintain an equilibrium of an internal environment.
- TGA (opal)
Answer:
Explained below
Explanation:
A mutation in a gene that results in total loss of the normal function of the gene product encoded by that gene, resulting in a Null phenotype.
Changes in DNA sequence are termed as nonsense mutation that introduce a stop codon, resulting in a non functional protein. This terminology results stop codons have also worked as nonsense codons.
There are three different stop codon-
In RNA
- UAG (amber)
- UAA (ochre)
- UGA (opal)
In DNA
- TAG (amber)
- TAA (ochre)
- TGA (opal)
