How is genetic diversity to beneficial to a species?
Crossing over causes genetic diversity. If there was no genetic diversity in a species, the species would be prone to extinction.

Is spontaneous generation valid?
Yes, it's possible with certain species. Bacteria is a living matter, and it can come from a nonliving substance. Therefore, spontaneous generation of life does occur, though it cannot occur with any species other than bacteria.
What is the word that means a beneficial relationship?
In nature a relationship between two organisms of different species is called symbiotic. These relationships can be both beneficial and harmful to one or the other. A relationship where one obtains a benefit without doing harm to the other is called commensalism. Where both species are benefitted it is called mutualism.
Explain how a species can change over time?
Through mutations in DNA. If a mutation is beneficial and helps the organism survive it is passed on to the next generation which leads to the evolution of a species causing it to change.
What does the term naturalized mean?
The process by which organisms that are better suited to their environment than others produce more offspring. As a result of natural selection, the proportion of organisms in a species with characteristics that are adaptive to a given environment increases with each generation. Therefore, natural selection modifies the originally random variation of genetic traits in a species so that alleles that are beneficial for survival predominate, while alleles that are not beneficial decrease. Originally proposed by Charles Darwin, natural selection forms the basis of the process of evolution.
How might a decrease in competition between species lead to the sudden appearance of new species?
The decrease in competition between species can lead to the sudden appearance of many new species because by the time there is a decrease between species more species are developing and that is causing more species to appear so suddenly.

Could animals species decrease in captivity?
Yes. If animal in captivity stop breeding then the species would decrease.
Mutations within the DNA sequence of an organism can?
Result in early embryonic death, disease, deformity, have no obvious effect, have a long term positive effect if the mutation is beneficial to the subject organism's species as a whole and if environmental pressure increases the survival rate of individuals with the trait. Frequency of occurrence can decrease or increase based on genetic drift in smaller isolated populations.
Why an egg is a beneficial to have as a species?
Well and egg is not a specific species. What kind of egg are you talking about?
When do you think cloning is beneficial?
Cloning is beneficial when an animal species or other organism species is becoming extinct. By cloning them, there will be more of them now, and enough of them to reproduce and naturally restore the population.

What would happen if individuals in a species were sterile?
Then it would be the end for that species in one generation.
Why would eliminating sea stars cause the number of species to decrease?
There are 1,500 species sea stars...so eliminating them would decrease the number of species by 1,500. Any species that rely on sea stars for food will be adversely affected as well.
