The correct answer is B. Predation

Explanation:

In ecosystems, one of the most common interactions between organisms is predation, this occurs when one organism feeds on others. This type of interaction includes a predator (organism killing and eating another organism) and prey (an organism that is being killed). Additionally, in predation is the predator the one that benefits completely, although this relationship is necessary to regulate the population of the prey. In the case presented, predation occurs because the sea snail eats the species of algae and therefore the seasnail is the predator while the algae are the prey.

Which is an example of an insertion mutation that changes all of the amino acids that follow the mutation?
astra-53 [7]

Answer:


2) CAG - TTC - ACG mutates to CAG - TTC - ACC - ACG

Explanation:

Insertions are mutations in which extra base pairs are inserted into a new place in the DNA. The number of base pairs inserted can range from one to thousands!

In option no. 1: We see that there is not addition of a single or more than one base, but the new base sequence is different from the original sequence at three places i.e: TTA - CAC - G

In option no. 2: The insertion of three bases ACC has been made exactly after TTC, the whole sequence and arrangement of bases remain same except this insertion.


In option no. 3: The first base of the sequence T is replaced with A, and all other sequence is same. This type of mutation is called substitution in which one base is replaced by other.


In option no. 4: The last base of the sequence C is deleted, and is not present in new sequence. This type of mutation is called deletion in which a base is removed from the sequence.


Conclusion: Therefore, the best option is 2, in which whole codon is inserted in the DNA base sequence.

Distinguish the types of forgetting: anterograde amnesia, retrograde amnesia, encoding failure, retrieval failure, and interfere
Karo-lina-s [1.5K]

Answer:

Anterograde amnesia is the inability to create new memories after the onset of amnesia, while memories from before the event remain intact. Brain regions related to this condition include the medial temporal lobe, medial diencephalon, and hippocampus. Anterograde amnesia can be caused by the effects of long-term alcoholism, severe malnutrition, stroke, head trauma, surgery, Wernicke-Korsakoff syndrome, cerebrovascular events, anoxia, or other trauma. Retrograde amnesia is the inability to recall memories made before the onset of amnesia. Retrograde amnesia is usually caused by head trauma or brain damage to parts of the brain other than the hippocampus (which is involved with the encoding process of new memories). Brain damage causing retrograde amnesia can be as varied as a cerebrovascular accident, stroke, tumor, hypoxia, encephalitis, or chronic alcoholism. The there is encoding failure. Encoding is the process of converting sensory input into a form able to be processed and stored in the memory. However, this process can be impacted by a number of factors, and how well information is encoded affects how well it is able to be recalled later. On the other hand, retrieval failure is the failure to recall information in the absence of memory cues. Proactive interference occurs when old memories hinder the ability to make new memories. In this type of interference, old information inhibits the ability to remember new information, such as when outdated scientific facts interfere with the ability to remember updated facts. This often occurs when memories are learned in similar contexts, or regarding similar things. It’s when we have preconceived notions about situations and events, and apply them to current situations and events.Retroactive interference occurs when old memories are changed by new ones, sometimes so much that the original memory is forgotten. This is when newly learned information interferes with and impedes the recall of previously learned information. The ability to recall previously learned information is greatly reduced if that information is not utilized, and there is substantial new information being presented. This often occurs when hearing recent news figures, then trying to remember earlier facts and figures.
