Answer:
13 is the answer for both
Explanation:
The atomic number is also the atoms count of protons and electrons when the element is of a neutral charge.
Answer:
Please the explanation below
Explanation:
DNA synthesis occur at the S phase of the cell cycle in preparation for cell division. The process which is also known as DNA replication occur in 3 main stages namely:
- Initiation
- Elongation
- Termination
At the initiation stage, the double helix DNA structure is unwound by DNA helicase enzyme to form a Y shape structure known as the replication fork. A short pieces of RNA called primer then binds to 3' end of the DNA strands at the starting point of replication.
During elongation, an enzyme known as DNA polymerase adds bases to the primer in the 5' to 3' direction. This makes the replication of the leading strand to be continuous. RNA primer binds to the lagging strand at multiple regions and are replicated in short disjointed fragments known as okazaki fragments. This kind of replication is discontinuous.
Termination involves the unbinding of RNA primer by an exonuclease enzyme. The primers are then replaced by relevant bases. Proofreading of the newly synthesized strands takes place and the okazaki fragments are joined together by an enzyme known as DNA ligase. Telomerase enzyme then adds telomeres to the end of the DNA strands and each newly synthesized strand winds to its parent strand.
Answer:
Sign stimulus
Explanation:
Sign stimulus is a stimulus that will always produce the same behavioral response of an organism. In this case, red coloring is a sign stimulus for the fish attack which is its behavioral response.
This type of innate behavior is called Fixed Action Pattern (FAP) because it is always the same (there is usually no variants in the behavioral response actions). If the model is colored differently, there is no behavioral response (attack).
