Explain the adaptive-inactivity theory of sleep.

2 answers:

One of the earliest theories of sleep, sometimes called the adaptive or evolutionary theory, suggests that inactivity at night is an adaptation that served a survival function by keeping organisms out of harm's way at times when they would be particularly vulnerable.

Answer:

Adaptive theory of sleep is also called as evolutionary theory which states that period of inactivity evolved as a means of conservation of energy.

According to the adaptive inactivity theory of sleep all species have a adopted tendency to sleep at the time period when waking is dangerous for the species.

It says that sleeping is necessary and it is a strategy of the body to conserve energy in order to stay energetic and healthy.

What are the two theories that are combined in the synthetic theory of evolution?

Alika [10]

The Modern Synthetic Theory of Evolution combines the Darwinian theory of evolution with Mendel's genetic theory.

<h3>Synthetic theory of Evolution </h3>

The synthetic theory of evolution states that evolution are the changes occurring in the allele frequencies within the populations.

The theory explains that changes in the genes of organism are what causes the evolution of organism.

The Darwinian theory of Evolution states that organisms better adapted to their environment survive and give birth to offspring suited for their environment.

The Mendelian theory of genetics states that the combination and resassortment of genes are responsiblefor character inheritance.

Therefore, the Modern Synthetic Theory of Evolution combines the Darwinian theory of evolution with Mendel's genetic theory.

During meiosis i, assuming no crossing over, what chromatid combination(s) will be present at the completion of prophase i?

arsen [322]

Answer

Crossing over is the phenomenon in which exchange of chromtids occur between non sister chromatids and result into recombinant chromatids, which is an important tool for evolution and bring about genetic changes in offsprings as compare to their parents.

No crossing over

If no crossing over occurs, it means no exchange of chromatids between non sister chromatids of homologous chromosomes, then no recombinant chromatids will be formed.

Result

At the end of meiosis II, when four haploid cells are formed, all these cell will contain similar chromosomes as present in parent. Thus chromosomes are non recombinant because of no crossing over.

Answer:

In many species, females choose the male they will mate with. For their part, males try to be chosen as mates. They show females that they would be a better mate than the other males. To be chosen as a mate, males may perform courtship behaviors. These are special behaviors that help attract a mate. Male courtship behaviors get the attention of females and show off a male’s traits. These behaviors are often observed as direct competition between males. Different species have different courtship behaviors.
