Lightweight beaks, heavy teeth, stability in flight
Answer: RNA is a more stable molecule than DNA
Explanation: DNA (deoxyribonucleic acid) is much stable than RNA (ribonucleic acid) for many reasons; Frist of all its because of the double strand of the DNA versus the single-stranded RNA. This is thanks to the Hydrogen bonding between bases since those bondings release free energy that allows the molecule to be provided by more thermodynamic stability.
Also the lack of 2′ OH groups makes DNA more stable since the OH groups are very reactive by themselves. In the DNA sugar molecule there is not a spare OH group that could start reacting on its own. So this is why DNA is immune to chemical reactions, while RNA (having an extra OH group) is more chemically "promiscuous".
Answer:
True
Explanation:
A group of organisms of the same species, living in the same area at the same time.
Answer:
When a new infertile hybrid appears in an environment, it feels like an anomaly in the environment and there are no possible measures to classify it as a new specie or a member of a specie just by a physical examination. When 5110 subject appears in that environment it is possible to classify it as a piece of a terminated branch of only one member as an anomaly of the closely related species.
His fate is solely relied on better care of himself for a good life span cause there are no other measures to save him. Futhermore added he is also not a proper member of a specie so no mating oppurtunities at all.
