This question involves a gene coding for feather colour in some birds in which the black allele (B) and white allele (W) is involved. According to the question the gene coding for feather colour exhibits co-dominance i.e. both the black (B) and white (W) allele are expressed in a heterozygous state (BW) to form an erminette phenotype.
Hence if the neither alleles is dominant or recessive over the other. The black phenotype will only be expressed when the genotype is BB.
The white phenotype will only be expressed when the genotype is WW
The combination of both alleles which results in the simultaneous expression of both in the erminette phenotype will be BW genotype.

Which type of transport requires the added energy of ATP?
A. active
B. passive
Answer: A. active
Explanation:
Answer:
(A)Active Transport
Explanation:
Active transport
During active transport, substances move against the concentration gradient, from an area of low concentration to an area of high concentration. This process is “active” because it requires the use of energy (usually in the form of ATP).

Compare the plant cell system vs the plant organ system. Plant Cell. Plant Organ System. 1. Nucleus. 1. Shoot system (Leaves, buds, stems, flowers, fruit) 2. Chloroplasts. 2. Root system 3. Cell wall 4. Mitochondria 5. Large vacuole 6. Cytoplasm
Answer:
Comparison is given below.
Explanation:
Nucleus controls and regulates the activities of the cell such as growth. Shoot system is the part of plant body present above the soil. The main function of shoot system is the production of food in the process of photosynthesis. Chloroplast is the where photosynthesis occurs. Root system is present inside the soil that is responsible for the absorption of water and nutrients from the soil. Cell wall is the boundary of cell whereas mitochondria is the powerhouse of the cell because energy for the cell is produced here. Large vacuole is the organelle that is responsible for the storage and waste disposal. Cytoplasm is the liquid medium in which the organelles are present in or over the surface.
why does the oceanic crust continuously subduct
Answer:
When an oceanic plate converges with a continental plate, the oceanic crust will always subduct under the continental crust. As the oceanic crust is naturally denser, this melting leads to heat being transferred upwards and uplifting the crust, eventually developing into a volcano.

17. To produce the same intensity and color of light, you can choose from a 60-watt incandescent bulb, a 17-watt compact fluorescent bulb, or a 10 watt LED bulbWhich is the most energy efficient?
a. The incandescent bulb.
b. The compact fluorescent FL) bulb.
c. The LED bulb
Answer:
10 watt LED bulb.
Explanation:
The most energy efficient is 10 watt LED bulb because it produces more light by consuming less amount of energy. If a substance is more efficient so it consumes less amount of energy for doing its work while on the other hand, less efficient substances uses high amount of energy for doing its work so that's why we can say that 10 watt LED bulb is more efficient its as compared to incandescent bulb and a 17-watt compact fluorescent bulb which uses high amount of energy.
A specific location in America has closed down several fossil fuel units and set up geothermal plants. In your own words, explain how this would affect the economy of the location. (5 points)
Answer:
The economy of the location would be affected in the following ways:
1. Setting up geothermal plants would create more Jobs as expertise in various fields would be required to render their services.
2. Setting up geothermal plants would increase more revenue generation for the government in taxes.
3. Setting up geothermal plants would attract the development of the location as more people would tend to live there, there would also be improved road networks, housing, e.t.c.
4. Closing down fossil fuel units would eradicate environmental pollution in terms of oil spillage and stop the reduction that has been ravaging agricultural activities due to contamination of water bodies and land as a result of the fossil fuel.
Explanation:
Geothermal power plants are expensive but renewable sources of electricity that use steam or hot water pumped to the Earth's surface from beneath the earth's crust to spin a turbine producing electricity.

Which of the following best explains why animals that inhabit warmer regions tend to have smaller body sizes?
A higher surface-area-to-volume ratio facilitates heat loss.
Animals in warmer climates need to move more quickly to catch prey.
More species inhabit warm climates, and smaller size enables a greater number to live in the same ecosystem.
Smaller body size enables faster reproduction and repopulation to maintain a niche in overpopulated warmer climates.
Answer:
I believe it may be a higher surface area to volume ratio facilitates heat loss
Explanation:
Out of the options it makes the most sense being that larger animals keep heat in...
Describe the three factors required for natural selection to occur in a population.
Answer:
Isolation,adaption,overpopulation
Natural selection is based on three principles which are as follows:
1. Hereditary/ inheritance
2. Competition
3. Differentiation
What is Natural selection?
Natural selection, is defined as the differential survival and reproduction of individuals due to differences in phenotype, is the dominant mechanism of evolution which is the change in the genetic properties of populations over generations.
Natural selection is based on three principles that most traits are inherited which is called heredity, more children are born that can survive which is called competition, and children with more desirable characteristics will survive and produce more offspring which is called differentiation.
Thus, Natural selection is based on three principles which are as follows:
1. Hereditary/ inheritance

Name the type of circulatory system found in the phylum Arthropoda
Answer:
Open circulatory system
Explanation:
An open circulatory system, found in arthropods, pumps blood into a cavity called a hemocoel where it surrounds the organs and then returns to the heart(s) through ostia (openings). The blood found in arthropods, a mix of blood and interstitial fluid, is called hemolymph.Arthropods have an open circulatory system. In an open circulatory system, blood isn't transported in the body through veins and arteries; it flows freely within body cavities and makes direct contact with the organism's internal tissues and organs! Most arthropods that live in the water have gills.

humans developed antibiotics to fight bacterial infections however some antibiotics are no longer effective in killing the bacteria than once killed how does the theory of evolution explain this antibiotic mutated the bacteria which allowed resistance develop
Answer:
Changes in genetic makeup occurs with the passage of time.
Explanation:
Antibiotic cause mutation in the bacteria which allowed to develop resistance in the bacteria. This resistance and change in the genetic makeup obeys the theory of evolution which states that all species are changed gradually with the passage of time. The genetic makeup of bacteria also changes with the passage of time and attain resistance due to regular application of antibiotics so due to this resistance, the antibiotic can't work on the bacteria.

Which of the following is TRUE about sedimentary rock?
A. does not contain layers
B. May contain fossils
C. the hardest of the rock types
Answer:
B
Explanation:
Sedimentary rock is layered. That makes A wrong, but it leads to another observation.
Things can die and think sink to the bottom of an ocean or sea or river or lake bed which over time changes. So you might find fossils which is the answer.
C is incorrect because there are much harder substances than sedimentary rock.
Answer:
B.May contain fossil.
Explanation:
These rocks are formed with the deposition of materials broken down from pre-existing rocks, followed by compaction and cementation
