There is a moth in England called the peppered moth. Before Britain's industrial revolution, these moths were usually salt and pepper colored. Because of their coloring, they blended in well with the tree trunks on which they tended to rest. The coloring helped them hide from the birds that ate them. During the British industrial revolution, industry expelled a lot of soot from the burning of coal into the environment. This soot darkened the tree trunks, and it was noted that black-colored moths were becoming predominant. The idea is that with soot in the environment, black-colored moths fared better than light-colored moths. There is some debate as to whether this is actually the case or not, but for the sake of this question, let's assume it is. In your own words, explain the concepts from the four observations discussed in 12.2 using the moth as an example. In other words, how does the moth illustrate the first observation, the second observation, etc.
Answers
Answer:
The correct answer is - natural selection in moths.
Explanation:
This is an event of historical Industrial melanism, an event caused by the process of natural selection. Due to this event, the evolution of dark body colors in moth species that present in such habitats become black by industrial soot.
Peppered moths in the UK were pale grey before the revolution of industries, But after the habitat become polluted with soot from coal‐fired industries, melanic snd become numerous and spread to other regions.
After the century the pollution comes down and the pale phenotype becomes the predominant form.

Explain how specific membrane-bound organelles of the keratinocytes are used to produce, transport, and modify aquaporin polypeptides from mRNA.
Answers
Answer:
Epidermis.
It is composed of keratinized, stratified squamous epithelium and is made up of 4 layers of epithelial cells depending on its location in the body. From deeper to superficial these layers are stratum Basale, stratum spinosum, stratum granulosum, and stratum corneum. The cells in all the layers except for stratum besele are called keratinocytes which is a cell that manufactures and stores the protein keratin.
Stratum Basale.
It is a cuboid-shaped stem cell that is a precursor of the keratinocytes of the epidermis. Two other cell types found in this basal cell are Merkel cells which function as a receptor and are responsible for stimulating sensory nerves that the brain perceives as touch. The second is melanocyte that produces melanin pigment which gives the skin its color.
Stratum spinosum.
It is spiny in appearance due to the protruding cell processes that join the cells via a structure called desmosome. The desmosome cell interlock with each other to strengthen the bond between the cell. Keratinocytes in the stratum spinosum stats synthesizing keratin and release water-repelling glycolipid that helps to prevent water losses from the body.
Stratum granulosum.
They are grainy in appearance due to further change in keratinocytes as they are pushes from the stratum spinosum. The cells become flat as their membrane thickens to allow the production of protein keratin which accolades as lamellar granules within the cells.
Stratum Lucidum.
It is a smooth and translucent layer of the epidermis situated above the stratum granulosum. Keratinocytes containing these cells are dead and flat. Stratum lucidum cells are packs with eleiden derived from keratohyalin which give these cells their transparency and provide a barrier to water.
Stratum corneum.
This is the most superficial layer in the epidermis and it prevents penetration of microbes and dehydration of underlying tissues.
Dermis.-This is the inner layer of the skin and has the following functions.
Reticular layer
Just below the papillary layer, we have a much thicker layer called the reticular layer composing of dense connective tissue. It contains elastin fibers providing elasticity to the skin enabling movement.

Two populations of birds with somewhat different coloration live on two different islands. When birds from the two populations are brought together, they produce young whose appearance is intermediate between the two parents. These offspring can successfully breed with each other or with birds from either parent population, and all offspring of these pairings appear intermediate to various degrees. According to the biological species concept, the two populations on different islands ___.
Answers
Answer:
represent a single species
Explanation:
According to the biological species concept, a species can be defined as a group of organisms that can potentially interbreed (i.e., mate) in order to produce viable and fertile offspring. Based on this concept, the cohesion forces that maintain the integrity of the species as a single group are 1-interbreeding between its members and 2-reproductive isolation mechanisms that prevent successful mating between organisms from different species. In this case, both bird populations represent the same species because when individuals of these populations are brought together they can interbreed to produce viable and fertile offspring.

the producers had 6,000 kcal of energy , how much would be passed to the primary consumer?
Answers
Answer:
600 kcal
Explanation:
In an ecosystem, energy is transferred from one organism in a trophic level to another organism in another trophic level. Organisms called PRODUCERS are capable of deriving energy from the sun. However, when fed upon by PRIMARY CONSUMERS, only about 10% of the energy is transferred to them because most of the energy (90%) is lost as heat.
Hence, in this case where the producers had 6,000 kcal of energy, 10% i.e. 10/100 of 6000 = 600 kcal of energy will be transferred to the primary consumers.
You design an experiment to test the hypothesis that consuming caffeine increases a person's chances of developing a headache. Participants in the experimental group will be told to drink 8 ounces of caffeinated soda in the morning once a day for 10 days, and to abstain from drinking any other caffeinated beverages or soda. Which of the following is an appropriate control group for your experiment?
a) A group that drinks 8 ounces of decaffeinated hot coffee (no caffeine) in the morning once a day for 10 days and abstains from drinking any other caffeinated beverages or soda
b) A group that drinks 8 ounces of caffeinated soda once a day for 10 days in addition to their normal beverage habits
c) A group that drinks 8 ounces of decaffeinated soda (no caffeine) in the morning once a day for 10 days and abstains from drinking any other O caffeinated beverages or soda.
d) A group that does not drink soda (caffeinated or decaffeinated) or other caffeinated beverages for 10 days
Answers
Answer:
d) A group that does not drink soda (caffeinated or decaffeinated) or other caffeinated beverages for 10 days
Explanation:
In an experiment, two groups exist as follows: experimental group and control group. Experimental group is the group that receives the experimental treatment (independent variable) while the CONTROL GROUP is the group that does not receive the experimental treatment.
In this experiment, the experimental treatment is the CAFFEINATED SODA (contains caffeine). Hence, the appropriate control group for this experiment will be the group that does not drink any soda (whether caffeinated or decaffeinated) or other caffeinated beverages for 10 days.

There are a number of similarities, and some differences, between the Q cycle in the mitochondrial electron transport system and the PQ cycle found in the chloroplast electron transport system. Sort the items into the appropriate locations, depending on whether they are unique to the PQ cycle, unique to the Q cycle, or common to both.The cycle converts a two-electron transfer process into two one-electron transfer processes.Two electrons are transferred from the reduced carrier to cytochrome c.Addition of electrons one at a time generates a semiquinone intermediate.Used to translocate protons across a membrane.Two electrons are transferred from the reduced carrier to plastocyanin.
Answers
Answer:
1. unique to the PQ cycle:
Two electrons are transferred from the reduced carrier to plastocyanin
2. unique to the Q cycle:
Two electrons are transferred from the reduced carrier to cytochrome c
3. common in both PQ cycle and Q cycle:
- The cycle converts a two-electron transfer process into two one-electron transfer processes
- Addition of electrons one at a time generates a semiquinone intermediate
- Used to translocate protons across a membrane
Explanation:
The Q cycle (Q due to quinol) refers to the cycle by which electrons are transferred from ubiquinol to cytochrome c. This cycle is associated with the sequential mechanism of oxidation-reduction between ubiquinol and ubiquinone, also known as Coenzyme Q10 (CoQ10, used as electron carrier), in order to move protons across the inner mitochondrial membrane. In the first phase of the cycle, ubiquinol attaches onto the cytochrome c oxidoreductase, also called complex III (because this complex is the third complex in the electron transport chain), in order to transfer two electrons to the complex. On the other hand, the PQ cycle (PQ due to plastoquinone) refers to the cycle where plastoquinone transports electrons during light-dependent photosynthetic reactions. In the PQ cycle, the plastoquinone serves as an electron carrier through the membrane of the thylakoid. In the first step of this cycle, plastoquinone obtains two electrons from photosystem II and absorbs two protons from the chloroplast stroma, resulting in plastoquinol, which subsequently transfers electrons to plastocyanin in a process coupled with the generation of a proton gradient between the lumen of thylakoid discs and stroma.

When water evaporates from plants through leaves, it diffuses through tiny openings called stomatal pores. If the water vapor needs to diffuse a distance L through one pore to exit the leaf in a time t, what is the time needed for water vapor from the same leaf to diffuse through another pore of length 1.30 L
Answers
Answer:
L means same time.
Explanation:
Same time is needed for water vapor from the same leaf to diffuse through another pore of length 1.30 L because the evaporation takes place at the same time in the pore and water is evaporated to the atmosphere but more water is evaporated due to increase of surface area as compared to the other pore that have small opening so the time is same but the amount of water evaporated is different.

This question may be completed independently or as a group exercise. You have learned that humans have 46 total chromosomes, and chimpanzees have 48 total chromosomes. Use other textbooks in biological anthropology and biology (or reputable online resources) to find the number of chromosomes in other organisms. Give an organism with considerably more chromosomes than humans. Give an organism with considerably fewer chromosomes than humans. Did your findings surprise you
Answers
Answer:
In comparison to humans, there are more chromosomes in the Hermit crab that is 127 pairs of chromosomes for a grand total of 254 and in Myrmecia pilosula has fewer chromosomes than humans.
The complexity of an organism or how advance is an organism has nothing to do with the number of chromosomes it had. The chromosome number is subject to change over time. Human ancestors had more chromosome numbers as compared to now but they are not advanced to us.
