Answer:
Signal the end of protein-coding sequences
Explanation:
The codons UGA, UAA, and UAG are known as stop codons. When the RNA is being translated to protein, and the RNAm reads those codons, it knows it has to end the protein sequence
a molecule is made up of atoms or ions
some molecules found in the human body are H20 or CO2 or O2
Answer:
the rate of change of velocity with time is called acceleration.
it can also be defined as the increase in velocity per second.
The S.I. unit of acceleration is meter per second square or ms−2.
formula; a = Δv / Δt
where a is acceleration,
Δv is the change in velocity,
and Δt is the amount of time it took for that change to occur.
The correct answer would be DIFFUSION. The mechanism that controls water changes in the cells by the movement of water from an area of high water concentration to an area of low water concentration is called Diffusion. This mechanism continues until there is balance in the water concentration. On the other hand, Osmosis is the movement of water from an area of low water concentration to an area with high water concentration.
Answer:
B
Explanation:
Chemistry starts with the atom as this is the building block of all chemistry.
The cell, nucleus, and enzyme are all part of biology and not chemistry (at this level at least)
