I’m pretty sure a nucleotide. Since it seems to be made up of a phosphate group, pentose sugar, and nitrogenous base. Hope this helps!
Answer:
yes
Explanation:
Because the most common isotope of hydrogen consists of a single proton and a single electron, a hydrogen ion is commonly referred to as a proton.
Explanation:
Organisms (within populations) exhibit individual variation in appearance and behavior. These variations may involve body size, hair color, facial markings, voice properties, or number of offspring.
Answer: DNA
Explanation:
Analyzing DNA from present-day and ancient genomes provides a complementary approach for dating evolutionary events. Because certain genetic changes occur at a steady rate per generation, they provide an estimate of the time elapsed. These changes accrue like the ticks on a stopwatch, providing a “molecular clock.” By comparing DNA sequences, geneticists can not only reconstruct relationships between different populations or species but also infer evolutionary history over deep timescales.
Answer:Self-assembly into a simple membrane
Explanation:
The cell membrane is the biological membrane that separates the interior of the cell to the exterior of the cell.
The cell membrane is made of lipid by-layer. The first cell membrane was made of lipids. It is so because it has the ability to assemble and form a membrane like structure.
It helps in entry and exit of the substances from inside of the cell to outside and vice versa.
