i) Because the worms would have either learned to become night worms or all day worms would have been eaten faster than they could reproduce
ii) Natural selection. Humans had no interaction with which worms survived, so it's all natural.

W Within a forest ecosystem, there is a large amount of diversity among members of a warbler species. Of the following stages of meiosis illustrated for a typical cell, which contributes most to diversity among the warblers? Pay special attention to the chromatids.
Answer:
Explanation:
How a Forest Ecosystem Matures . Forest ecosystems tend to always be moving toward maturity or into what foresters call a climax forest. This maturing, also called forest succession, of the ecosystem increases diversity up to the point of old age where the system slowly collapses. One forestry example of this is the growth of trees and the entire system moving toward an old growth forest.
A Large amount of warbler species, crossing over between homologous chromosomes, is closely involved in genetic variation. The stage that most contributes to diversity is stage C, where you can see chromosomes after crossing-over.
There are different mechanisms involved in producing genetic variation among descendants, are-
Crossing-over between homologous chromosomes (prophase 1), The Random lining of homologous chromosomes (metaphase 1), Random fertilization
The Crossing-over events occur between two homologous chromosomes within the equatorial plane and make the daughter cells genetically different from the first one.
The Chiasma is the position where two homologous chromatids interchange genetic information, giving an area for brand spanking new genetic material or information to be provided to descendants.
After crossover, homologous chromosomes get separated again. In the attached image there are four different stages of meiosis.
Stage C is the one that contributes foremost to diversity. We can see that crossover has already occurred between homologous chromosomes and that they have already interchanged segments.
In the image, you will see the difference between chromosomes that have gone through the crossing over mechanism, and chromosomes that have not. The difference in color represents segments interchange and variation.
Therefore, that answer shows the contribution to diversity among the warblers.

Answer:
Ecological tolerance refers to the ability of an organism, or animal to be able to adapt and survive changing environmental conditions.
The combination of factors that would result in an island community with the lowest ecological tolerance would be option B Introduction of invasive species, increased deforestation because with the introduction of invasive species, there would be more competition for natural resources such as food, water, sunlight; and with increased deforestation, there is greater chances of soil erosion.

Insular biogeography or island biogeography is a field within biogeography that examines the factors that affect the species richness and diversification of isolated natural communities. The theory was originally developed to explain the pattern of the species–area relationship occurring in oceanic islands.
The reptile population decreases as arthropods decrease with their habitat
Migrating species are more likely to find larger habitats over smaller ones. Explanation: The concept of island biogeographical model establishes that larger islands and habitats will have a larger number of species than a smaller island. Larger islands have more tendency to attract new species.The species–area relation, whereby the number of species in a spatial unit increases with that unit’s area, well predates the MacArthur and Wilson theory of island biogeography, having been documented for about 150 years. Two general kinds of models for this relation have been proposed. The first has number of species predicted from an assumed species–abundance distribution and the total number of individuals of all species combined (assumed proportional to area). The second develops species–area relations from MacArthur and Wilson’s species-equilibrium approach.

In this location, a thunderstorm is expected, a thunderstorm is a small-scale storm that includes both thunder and lightning.
What is a thunderstorm?Some thunderstorms have a chance of producing hail and/or tornadoes. Localized heavy snow showers during the winter may also include thunder and lightning. Additionally, it frequently delivers heavy rain as well as violent gusts.
Thunderstorms are ferocious, brief meteorological disturbances that are nearly always accompanied by lightning, thunder, thick clouds, significant amounts of rain or hail, and strong gusts of wind.
Layers of warm, moist air rise in a strong updraft to cooler areas of the atmosphere, whereupon thunderstorms form.
Therefore, according to all directions shown in the image thunderstorm weather is expected at the location.

On a scratch sheet of paper, complete the Punnett square of the cross between two heterozygous red-eyed flies (Rr). What color eyes will the offspring have?
Answer:
75% red, 25% other color (brown?)
Explanation:
A cross between two heterozygous red eye flies (Rr x Rr)
R r
R RR Rr
r Rr rr
The possible genotypes are RR, Rr, and rr. There are two possibilities of Rr.
Since the heterozygotes have red eyes, the red eye allele must be dominant. Therefore, RR and Rr genotypes will all have red eyes. That means 3/4 (75%) of offspring will have red eyes. 1/4 25% are h0m0zygous recessive (rr), and will therefore have the other eye color (question doesn't mention which colour this is, it is likely brown)

Explain how heat can be a source of water pollution.
Answer:
Decreases amount of available oxygen in water causing some fish to decay because of the lack of oxygen.
Explanation:
Heat boosts fish metabolism and lowers water's ability to hold dissolved oxygen, making it a water pollutant. Low-dissolved oxygen water kills game fish like trout.
Why is heat a source of water pollution?The ability of water to keep dissolved oxygen in solution is reduced when heat is present, and fish have a faster metabolic rate when heat is present. For these reasons, heat is regarded to be a pollutant in water. In waters with exceptionally low concentrations of dissolved oxygen, game fish such as trout and other valuable species simply are unable to live.
The release of warm water into existing bodies of water is referred to as thermal pollution. Thermal or nuclear power plants, industrial effluents such as petroleum refineries, pulp and paper mills, chemical plants, steel mills and smelters, and sewage effluents, as well as biochemical activity, are the primary contributors to thermal heat pollution. Other contributors include biochemical activity.
