Answer: Option A
Explanation:
ESTs are Expressed sequence tags, which are the segments of mRNA sequences that is derived through the single sequence reactions performed on the clones from cDNA libraries which were randomly selected.
This is possible by the help of bioinformatics that this much of data is available nowadays for study and research purpose.
Till date we have 45 million expressed sequence tags obtained from over 1400 species or can be said as eukaryotic species.
Answer:
Your carbon atom enters the leaf as CO2 (carbon dioxide) from the atmosphere. In the leaf, chlorophyll uses the energy from the sun to convert CO2 and H2O to the sugar glucose, C6H12O6. Your carbon atom is part of this molecule; it is now one of the carbons in the glucose.
Next, the glucose carrying your carbon atom is sent down the phloem tissue of the carrot plant to the root, which is the carrot itself. Enzymes in the carrot root connect the glucose molecule with your carbon atom into a chain with other glucose molecules, forming cellulose, or plant starch, and there you go. Your carbon atom went from being part of an atmospheric gas to a starch via photosynthesis and starch formation in the root.

Answer:
The correct option is 'the ability to absorb other cells gave some prokaryotes a survival advantage.'
Explanation:
The scientists have brought forward the theory of endosymbiosis which explains how eukaryotic cells evolved from prokaryotic cells. According to this theory, the scientists claim that the organelles found today in the cells, once existed as individual prokaryotic cells. These organelles were engulfed by larger prokaryotic cells with time and hence, the eukaryotic cells evolved from these prokaryotic cells. The larger prokaryotes might have engulfed the smaller cells for survival.
Answer:
In order to breathe as an amniote does, the terrestrial salamander would have to <u>develop new musculature associations in the ribcage.</u>
Explanation:
The solid respiratory musculature in amniotes is a transformative trait of them, which can't in the earthbound lizard. During the existence time of lizard it utilizes various organs for breath and it again differs with species. It might utilize, skin, gills or lungs for the procedure of breath, though amniotes only breath through lungs.
c oxygen is released for photosynthesis
