Explain incomplete dominance, using snapdragon
flowers as an example.
Answer:
Dominant allele does not completely conceal recessive allele.
Snapdragon with genotype Rr (R being red and r being white), would have a phenotype of pink flowers.
Explanation:
Incomplete dominance is where a dominant allele is not able to completely conceal a recessive allele, usually leading to a phenotype which appears to be a combination of the two.
For example, in snapdragons:
The allele for red flowers (R) is dominant over the allele for white flowers (r). Let's say a snapdragon flower had the genotype Rr, one allele for red flowers and one for white. In the case of 'normal' dominance the dominant red flower allele (R) would mask the effects of the recessive white flower allele (r), resulting in the phenotype (outward observable characteristics) of having red flowers.
However here in the case of incomplete dominance, the dominant allele would not be able to fully cover up the effects of the white flower allele, meaning that both colors (red and white) are expressed in the phenotype, resulting in pink flowers.
Hope this helped!
Answer:
Incomplete dominance is seen in offspring that have a third phenotype not seen in the parents. Snapdragons are an example. The third phenotype results when a snapdragon with the red pigment protein crosses with a snapdragon with a defective gene that produces no pigment, resulting in a white snapdragon. The offspring receive one allele from each parent, resulting in half the amount of pigmentation for red color being expressed. The offspring will be pink snapdragons instead of red or white.

Inhibitors of the electron transport chain exert their effects through a variety of mechanisms.
____________ blocks electron transport and proton pumping via inhibition of Complex IV.
____________ blocks electron transport and proton pumping via inhibition of Complex I.
____________ blocks electron transport and ATP synthesis by inhibiting the exchange of ATP and ADP across the inner mitochondrial membrane.
Answer:
Azide and Carbon monoxide block electron transport and proton pumping via inhibition of Complex IV.
Rotenone blocks electron transport and proton pumping via inhibition of Complex I.
Atractyloside blocks electron transport and ATP synthesis by inhibiting the exchange of ATP and ADP across the inner mitochondrial membrane.
Explanation:
The mitochondrial electron transport chain is composed of different complexes integrated into the inner mitochondrial membrane, which function to generate an electrochemical proton (H+ ions) gradient that is then used to drive the synthesis of ATP, the energy coin of the cell. The mitochondrial complex I catalyzes the electron transfer from nicotinamide adenine dinucleotide (NADH) to ubiquinone and then transports H+ ions across the inner mitochondrial membrane. Moreover, the mitochondrial complex IV, also known as Cytochrome c oxidase, receives electrons via the cytochrome pathway in order to complete the reduction of oxygen (O2) into two molecules of water (H2O). Azide is a selective inhibitor of the complex IV which acts as an uncompetitive inhibitor with regards to O2, while carbon monoxide (CO) binds to the cytochrome c oxidase enzyme, thereby suppressing its activity and thus disturbing ATP synthesis. Rotenone is a potent inhibitor of the mitochondrial complex I that inhibits electron transfer from the iron-sulfur centers in the complex I to ubiquinone, thereby blocking ATP synthesis. Finally, atractyloside is a competitive inhibitor that inhibits the transport of ADP across the mitochondrial inner membrane by blocking the ADP/ATP translocator, thereby preventing ADP from entering mitochondria.
The F2 generations of dihybrid crosses of Labrador retrievers are expected to produce the recessive epistatic ratio of 9 black: 3 chocolate: 4 yellow dogs. A random sample of 80 dogs was taken from F2 crosses. What is the expected number of yellow labs in the sample and what number of degrees of freedom is needed for a chi-square test of recessive epistasis

Which two types of biotechnology share a common goal of producing future generations of a population that share a particular desired trait?
A.DNA Fingerprinting and gene cloning
B.bioremediation and reproductive cloning
C.Selective breeding and genetic engineering
D.gene therapy and yeast fermentation
Answer: B. Selective breeding and genetic engineering.
Explanation:
The goal of selective breeding is to produce organisms that have a disered trait through only breeding said specis with that traits. (for example, farming breeds animals that are better for food.)
The goal of genetic engineering is to take a trait from one organism and apply it to another. (For example, putting artic fish gentics into a tommat so that it won't freeze.)
In conclusion, both of these processes serve the common goal of creating more disered organisms artifically.

How does the population of red-tailed hawks affect the population of prairie dogs living in the meadow? How does the population of prairie dogs affect nonliving parts of the meadow, such as soil? Help, please.
Answer:
Explanation:
Red tailed hawks will often prey on prairie dogs. The hawks will eat the prairies dogs so they will lessen the population. Prairies dogs create more fertile soil, so this allows plants to germinate, or grow. This results in more food for prairie dogs and thus more food for hawks.

A wealthy homeowner in Siberia, where the growing season is short, wants fresh tomatoes all year round.
Quonset hut greenhouse
hydroponic greenhouse
plastic sheeting greenhouse
polycarbonate greenhouse
Answer:
hydroponic greenhouse.
Explanation:
Hydroponic greenhouse is a type of greenhouse that would be best in Siberia where the growing season is short and we wants fresh tomatoes all year round. Tomato plants are able to grow takes less time in hydroponic greenhouse because plants grow 30% to 50% faster in hydroponics than when grown in soil. Under the right conditions, the productivity of tomato is higher three and 10 times as compared to traditional methods of tomato cultivation.
Explain how temperature and amount of precipitation can affect the type of plants and animals found in the desert biome?
Answer:
A influência da vegetação sobre o clima acontece de diferentes formas, influenciando tanto no albedo quanto na umidade e nas variações de temperatura. Isso significa dizer que alterar a cobertura vegetal de um dado local é também propiciar alterações climáticas no local da intervenção e também em outras partes do planeta. A consequência de uma maior umidade do ar é a menor amplitude térmica (a diferença entre a maior e a menor temperatura), ou seja, a ocorrência de médias de temperaturas mais constantes. Isso ocorre em razão do calor específico da água, responsável por conservar o calor por mais tempo.
Explanation:
Answer: In the desert biome the temperature's are extreme. They could get to over 100 degrees. Plants and animals adapted to their environment over man centuries. The amount of precipitation a plant or animal get can effect how they grow. Plants need lots of water so the can grow and flourish and animals need it so they can live. If the don't get enough then they could die. Th plants there need to endure long-spread drought. So they need deep roots so they can soak up lots of water. animals like the coyote go out in the night. when it's cooler. they hunt lizards.

An animal engaging in commensalism is as basic as a bird building a nest in a tree. Without being considerably injured or influenced by the bird, the tree offers the bird shelter and protection. Thus option A, E is correct.
What defines about Commensalism symbiotic relationship?A symbiotic relationship known as commensalism occurs when one species benefits while the other is unaffected. Usually, one species exploits the other for something outside food. For instance, mites will cling to larger flying insects to “hitch a ride.” Hermit crabs live in the dead snails' shells.
A relationship between members of two species when one species receives food or other benefits from the other without endangering or helping the latter. Commensalism.
