Dr. Evil has just discovered a way to prevent mating from occurring during meiosis in the gametes of his lab rats. the effects her discovery would have on laboratory mice is that prophase I would be interrupted and there would be reduced genetic variation in the offspring of the mice. because crossover occurs during prophase I of meiosis I and results in genetic recombination, which promotes genetic variation. If this is avoided, genetic variation would be significantly reduced in the offspring.

<h3>What happens in prophase 1?</h3>

Prophase I – in this stage, the condensation of the chromosomes occurs; the temporary disappearance of the carioteca; disappearance of the nucleolus and the duplication of centrioles to the poles of the cell. In prophase, the exchange of genes (crossing-over) also takes place, through the exchange of pieces between homologous chromosomes.

With this information, we can conclude that Prophase I is the first stage of meiosis I. In it, the pairing of homologous chromosomes occurs and a phenomenon known as crossing-over can occur.

Lymphoid tissue is the body part that is an essential part of the immune system that provides immune response against different infection or pathogens and protects from these foreign bodies. These tissues are present in all over the body that includes spleen, adenoids, tonsils, lymph nodes and other parts.

Lymphoid tissues or organs are the sites of the proliferation of the macrophages and lymphocytes. These structures also assist in furnishing surveillance points for lymphocytes and macrophages.

skelet666 [1.2K]

Answer:

The correct answer is C. helps process explicit memories for storage.

Explanation:

The hippocampus is an structure of the brain and is located inside the temporal lobe. The main function of the hippocampus is to mediate the generation and recovery of memories in conjunction with many areas spread across the cortex and with other areas of the limbic system. It helps to process and recover the episodic memory (those related to events) and spatial memory (mode in which we perceive space or dimensions). This organ is also where short-term memories become long-term memories, that is, it acts as a mediator of memories, acting as an activation node that allows different memories distributed across different parts of the brain to be activated.
