Answer:
Explanation:
a bird feather is biotic because it was made on a living thing. fog is abiotic because its not living or was never living. i might be wrong about the feather tho.
Answer:
Correct choice should be:
"SGSG"
Explanation:
The cell cycle consists of G1, S, G2 and M phase. The former three phases include the interphase and M phase is the dividing phase of cell . G1 prepares cell for DNA synthesis. S phase is the phase where DNA replication takes place. G2 phase prepares cell for cell division or M phase.
G1 phase preceeds replication or S phase and G1 phase licences DNA replication.
During other phases of cell cycle, ORC complex masks origin of replication. ORC phosphorylation takes place at S phase, which removes this omplex and unmasks origin of repication site so that replication machinery can bind to it.
DNA helicase activation: S phase
DNA helicase deposition on DNA at the replication origins: G phase (actually G1)
ORC phosphorylation: S phase
Licensing of replication origins : G phase (actually G1)
Hence correct choice should be:
SGSG
The squirrels are attuned in their brains to understand that owls are a threat because it is a predator. This is visual stimuli that evolved over many years to elicit a conditioned response. This is an innate behavior (meaning that it has been pre-programmed into an animal's genes) and offspring are naturally born with it.
Answer:
Fermentation method is likely to occur in her cells so that glycolysis can continue to produce ATP
Explanation:
Through Fermentation and glycolysis ATP is produced without oxygen. The muscle cells of human under goes fermentation when their cells are running out of oxygen. To meet the need of oxygen, fermentation occurred in the cell of the athlete at the end of her race.
The conversion of glucose into a cellular energy and to a lactic acid is conducted in the cell, by lactic fermentation. This is anaerobic fermentation which occurs in some particular cell.
The answer is C, the mitochondria is the powerhouse of the cell
