I got you :)
The molecular clock (based on the molecular clock hypothesis (MCH)) is a technique in molecular evolution that uses fossil constraints and rates of molecular change to deduce the time in geologic history when two species or other taxa diverged. It is used to estimate the time of occurrence of events called speciation or radiation. The molecular data used for such calculations is usually nucleotide sequences for DNA or amino acid sequences for proteins. It is sometimes called a gene clock or evolutionary clock.
Answer:
Horizon A es deficiente en minerales.
Horizon B sufre la menor cantidad de cambios.
La roca madre se encuentra debajo de las capas del suelo.
Explanation:
Answer: d
Remember you always have to have the opposite letter (Chargaff’s rule). A=T G=C vice versa T=A C=G.
I hope this helps, I’m sorry if it’s a but confusing:)
Answer:
He experiences them because he still has more to learn. He takes those failures, and use them to his advantage. He gets better at what he's doing by learning from the failures and mistakes.
Answer:
Explanation:
Semiconservative replication is one of the type of replication methods proposed to take place in the cell and has also been confirmed to be the type that actually takes place in the cell. Semiconservative replication involves the production of two copies (of which one is the parental strand which acts as template and the other is the newly synthesized strand) of the original DNA molecule. A leading strand is the newly synthesized strange running in the 5' to 3' direction, the template strand runs from the 3' to 5' direction while the lagging strand is the newly fragmentally synthesized strand oriented in such a way that its production runs in the 5' to 3' direction for each okazaki fragment. Its template strand runs in the 5' to 3' direction.
The cell copes with errors in replication either by performing the 3' to 5' exonuclease proofreading during replication or by utilizing the cell's DNA repair system.
