Answer:
The earliest known life-forms are putative fossilized microorganisms, found in hydrothermal vent precipitates, that may have lived as early as 4.28 Gya (billion years ago), relatively soon after the oceans formed 4.41 Gya, and not long after the formation of the Earth 4.54 Gya.
Explanation:
A. Migration (birds migraye to warmer climates during colder months)
Answer:
Explanation:
False
Elastic collision is one where two colliding particles both lose some of the kinetic energy. gases tend to have lower densities than solids because gases have lower molar mass. ... if a gas and a liquid are both at the same temperature, the particles of gas have a higher average kinetic energy.
Answer:
The inducer will combines with the repressor and inactivates the pathway.
Explanation:
Inducer is a term in Molecular Biology, which represent a molecule or substance that has the capability to activate the transcription of a gene, where by it joins with and then inactivates a genetic repressor.
In other words, the inducer binds with the repressor in order to prevent the RNA polymerase to combine to the DNA, and chemically produce mRNA, this is done by repressor proteins combining with the DNA strand.
Inducer specifically makes repressor to change shapes, which will make it not combine with the DNA, and therefore, allow formation of transcription, such that expression of gene will eventually occur.
