Answer: Mutation. The allelic variations that make evolution possible are generated by the process of mutation, but new mutations change gene frequencies very slowly, because mutation rates are low. Assume that the gene allele A1 mutates to allele A2 at a rate m per generation and that at a given time the frequency of A1 is p.
Explanation:
Answer: D. An adaptive process that allows children to deal more efficiently with their environment.
Explanation:
Synaptic pruning is a natural process between early childhood and adulthood which occurs in the brain. The brain removes the extra synapses during synaptic pruning. Synapses are brain structures that allow the neurons to transmit to another neuron an electrical or chemical signal.
Synaptic pruning is thought to help the brain transition from adolescence, when it can quickly learn and make new connections, to adulthood, when it is much more stable in its structure, but can concentrate on a single question for longer and conduct more complex thinking processes. Synaptic pruning make brain more adaptive to the external environment in early ages.
Hence, the correct option is D. An adaptive process that allows children to deal more efficiently with their environment.
The question has been answered itself but the answer will contain the detail explanation.
Answer:
1. The replication fork formation during DNA replication is important for the continuity and the addition of the further base pair on the template. The DNA initiation process starts by the formation of replication fork.
2. The okazaki fragments are the short DNA fragments that are formed on the lagging strand. These fragments are later joined by the enzyme DNA ligase.
3. Leading strand is the continuous strand that formed during the DNA replication. The direction of the leading strand is 5' to 3' .
4. DNA polymerase is the main replicating enzyme during the DNA replication process. Different types of DNA polymerase with multiple subunits are present in prokaryotes and eukaryotes.
5. The new DNA that are formed from the parental strand and complementary with each other are called daughter DNA.
Answer:
B. Oxygen molecules recombine to allow cells to get larger
