What is burning of fossil fuels, slash and burn agriculture, and volcanic activity?
Answers
The burning of fossil fuels, slash and burn agriculture, and volcanic activity is called Air pollution.
Most automobiles and power plants burn fossil fuels. These non-renewable resources power nearly all manufacturing and other businesses. Carbon monoxide, nitrogen dioxide, sulphur dioxide, and hydrocarbons are a few of these pollutants.
Biomass is total amount of living material present in an environment. Burning biomass is done for slash-and-burn farming. The pollutants, which include CO2, carbon monoxide, methane, particulates, nitrous oxide, hydrocarbons, and organic and elemental carbon, are largely the same as those produced by burning fossil fuels.
When anything burns, particles are produced. Particulates can also be found in nature as a result of dust from wind or volcanic eruptions.

How are the line spectra of the different elements related to the observed color with the unaided eye?
Answers
Line spectra of different elements vary due to difference in wavelengths of emitted light.
To the unaided eye, the various wavelengths denoting colors of light given by an element are combined together, and appear as a single color that is a combination of the constituent colors.
Electrons in atoms usually occupy the lowest energy states possible (ground state). However, electrons can be excited to high energy states when they absorb excess energy.
When they return to the ground state, they release this excess energy in the form of light. Each atom or molecule releases a single photon of light for each electron energy transition it makes.

b) How would the rate of speciation be different if the islands were much closer together? Explain
Answers
Isolation, Divergence and Reproductive isolation are the three reasons of higher rate of speciation.
What are the three reasons that this area had a high rate of speciation?Isolation, Divergence and Reproductive isolation are the three reasons that this area had a high rate of speciation. Isolation of populations is the main reason of speciation. Divergence in traits of separated populations have different mating system or habitat. Reproductive isolation of populations causes the populations come into contact again and again.
How would the rate of speciation be different if the islands were much closer together?
The rate of speciation would be different if the islands were much closer together because the species can easily move from one island to another island which leads to diversification of population.

What factors might favor the evolution of semelparity versus iteroparity in different species of salmon?
A number of factors such as changes in water temperature, size at reproduction, energy loss during reproduction, and post reproductive feeding may significantly affect post reproductive mortality (Baird et al., 1986, 1987.
What is semelparity versus iteroparity?Living things have two different reproductive options: semelparity and iteroparity. A species is categorized as iteroparous if it experiences several reproductive cycles throughout its existence, and semelparous if it exhibits just one reproductive event before passing away
In truly semelparous species, death following reproduction is a component of a larger plan that includes optimizing reproduction at the expense of future existence. There will always be some iteroparous individuals who pass away between their first and second reproductive episodes, but this is not considered semelparity unless it is a symptom of a syndrome of programmed death after reproduction.

Answers
The greater the working distance of an objective lens, the lower the magnification.
Magnification:Magnification is the process of enlarging something's apparent size rather than its actual size. This enlargement is measured in terms of a calculated quantity known as "magnification." The term "minification" or "de-magnification" is frequently used to describe a reduction in size when this number is less than one.
Magnification frequently refers to enlarging graphics or images to view more detail, boosting resolution, using a microscope, printing methods, or digital processing. The viewpoint of the image is unaffected by image magnification in every situation.
The ratio of the image's height to the object's height is represented by the formula for magnification. Additionally, the letter "m" stands for the object's magnification. Additionally, its formula is
Magnification (m) = h / h’
Here, the object's height is indicated by the letters h and h'.
Additionally, it might be connected to the image and object distances. So, it can be written as follows:
