The peppered moth provides a well-known example of natural selection. The light-colored form of the moth was predominant in England before the Industrial Revolution. In the mid-nineteenth century, a dark-colored form appeared. The difference is produced by a dominant allele of one gene. By about 1900, approximately 90% of the moths around industrial areas were dark colored, whereas light-colored moths were still abundant elsewhere. Apparently, birds could really find the light morhs against the soot-darkened background in industrial areas and, therefore, were eating more light moths. Recently, use of cleaner fuels has greatly reduced soot in the landscape, and the dark-colored moths have been disappearing.
1.What forces are causing evolutionary change in these populations?
2. Should the two forma be considered separate species?
3. How would you determine if these are separate species?
4. Give a prediction for what future generations of moths will look like and explain why.
Answer:
a) Natural selection
b) Different
c) Different genotypes
d) Evolution of dark colored moth species from the light colored moth species
Explanation:
a) The pressure of selection due to the changing color of bark of tree because of air pollution caused by industries leads to natural selection in a way that dark colored moth are emerging
b) Yes the two forms of moths are two different species.
c) The genotype of the two species is different
d) All the moths will be of dark color in order to save themselves from predation. This will lead to evolution of dark colored moth species from the light colored moth species and hence will lead to extinction of light colored moth

In an early experiment, it was found that a mouse in a sealed glass jar soon died, but if a plant was included in the jar, the mouse lived much longer. Explain theses results.
Answer:
The correct answer is - mouse produces carbon dioxide which is used by the plants for photosynthesis that in turn produces oxygen that is used for cellular respiration.
Explanation:
A mouse can not live in a sealed container or jar for a long time whereas with a plant in a closed and sealed jar mouse can live longer. This is due to the fact that in absence of the plant there is no oxygen for the mouse to get perform cellular respiration.
in a jar with a plant, the mouse lives longer because the plant still produces oxygen by the process of photosynthesis which is used by the mouse for cellular respiration and produces carbon dioxide that is taken by the plant.

1.1 Cell division is found to occur in:
A growth
B reproduction
С
cancer
D all options.
Answer:
Cell division is found to occur in both groth and reproduction.The answer is D
Answer:
D all options.
Explanation:
Cancer
Cancer is unchecked cell growth. Mutations in genes can cause cancer by accelerating cell division rates or inhibiting normal controls on the system, such as cell cycle arrest or programmed cell death.
Reproduction
Cell division usually occurs as part of a larger cell cycle. Both of these cell division cycles are used in the process of sexual reproduction at some point in their life cycle.
Growth
In unicellular organisms, cell division is the means of reproduction; in multicellular organisms, it is the means of tissue growth and maintenance. Most tissues of the body grow by increasing their cell number, but this growth is highly regulated to maintain a balance between different tissues

Assume that sound A has a decibel level of 10 and sound B has a decibel level of 30. How many times louder is sound B than sound A?
Answer:
3 times louder

What is sound and types of sound?There are two types of sound:
Audible and Inaudible.Inaudible sounds are sounds that the human ear cannot detect.
Whereas human ear hears frequencies between 20 Hz and 20 KHz.

Polar bears live in the tundra. They obtain their energy almost exclusively from eating other animals, although they do eat some vegetation. Black bears that live in temperate forests tend to be more omnivorous, eating a wide variety of plants and animals for energy.
An adaptation is a behavior or an anatomical structure that can help an organism survive in its environment. Why are diet choices important adaptations for these animals’ survival in their biomes? Based on the images, what other adaptations do these animals display?
Answer:
In the tundra, vegetation is rare, so polar bears had to adapt to eat a heavily animal-based diet. In the temperate forest region, a wider variety of plants is available, so black bears can eat a more omnivorous diet. The bears’ colors are adaptations. The polar bear blends in with the snowy background, and the black bear blends in with the trees of the temperate background. The bears’ coloring could help them hunt for prey.

(4) The coral can be hurt by too much carbon dioxide being dissolved in the water from the air above.
(5) If the coral dies, the reef becomes bare rock and sand no longer full of life.
Answer:
(5) If the coral dies, the reef becomes bare rock and sand no longer full of life.
Explanation:
The atmosphere is a part of coral reef because a large population of organisms lives in these coral reefs. It provides habitat to the biosphere of the ocean as well as oxygen to the marine organisms. It can greatly affected with the increase concentration of carbondioxide due to acidification of water that kills the algae that is lives on the surface of these coral reef. So if these algae die due to lowering of pH, a large portion of marine organisms also removed from the environment due to unavailability of suitable environmental conditions.
