jeka94

Answer:

The correct answer is- activation synthesis theory

Explanation:

The activation-synthesis theory tells us about the role of neuron in dream production during sleep. It was first proposed in 1977 by Allan Hobson and Robert McCarley which was psychiatrists at Harvard University.

This theory says that in REM sleep some neurons in the lower brains for example in the brain stem randomly activates due to change in neural signals and dream occurs when the cerebral cortex tries to interpret the meaning of these neuron signal changes.  

So the correct answer to this question is- activation-synthesis theory.

Genetic variation helps populations adapt to a changing
timama [110]

Answer:

Please find the explanation below

Explanation:

Sexual reproduction is the kind of reproduction that requires two organisms (male and female) to form an offspring. The male organism produces gametes called SPERM while the female organism produces gametes called EGG. These two gametes come together in a process called FERTILIZATION to produce a zygote, which develops into an offspring.

In sexual reproduction, gametes are produced by organisms involved via a process called MEIOSIS. Meiosis, however, reduces the chromosome number of the gametes by half. However, one process unique to only meiosis and sexual reproduction is called CROSSING OVER.

Crossing over is the process whereby chromosome segments is exchanged between non-sister chromatids of homologous chromosome. This process causes a recombination of chromosomes (alleles) in such a way that the gametes will be genetically different from the parent organisms (genetic variation). According to this question, sexual reproduction leads to more genetic variation than asexual reproduction due to the process of CROSSING OVER that occurs in sexual reproduction.
