oak tree DNA is much longer than that in human and the number of chromosomes also differ
Answer: What does the endosymbiont hypothesis propose? It proposes that early eukaryotic cells acquired the precursors of mitochondria and chloroplasts by engulfing certain types of bacteria. ... Mitochondria, chloroplasts, and centrioles in eukaryotic cells each contain their own minute and unique supply of DNA.
Explanation:
The first piece of evidence that needed to be found to support the endosymbiotic hypothesis was whether or not mitochondria and chloroplasts have their own DNA and if this DNA is similar to bacterial DNA. This was later proven to be true for DNA, RNA, ribosomes, chlorophyll (for chloroplasts), and protein synthesis.
Globin 1 and globin 2 genes of insects are understood to have diverged approximately 170 million years ago, through duplication, from a common globin gene ancestor. The two genes that code for haemoglobin have conserved regions; oxygen-binding and heme- regions. Globin 2 gene has lost the intron region that is still present in the globin 1 gene. The percentage divergence is 7.2% with 20 varying nucleotides.
Answer:
Water shed is created when an area or land separates the water flowing to different rivers, basin and seas.
Explanation:
Water shed are of different types-
- Large water sheds-Contain well developed channel networks.
- Small water sheds-Contain dominant land phase.
- Urban watershed-It is dominated by building,roads,pavements.
- Agriculture water shed-
- Forest water shed-Evapotranspiration is the dominant component of the hydrologic cycle.
- Mountain water shed-mountain is the dominant component that separates the water flow.
- Desert water shed-Sand dunes sand mounds that are formed by blowing air causes separation of water flow.
- Coastal watershed-Coastal area may partly be urban and is dynamic contact with sea.The hydrology is influenced by tidal action.
Bar graphs show patterns in data with variables that change over time; Whereas pie charts, show data as parts out of a whole, (such as 100%).
