Answer:
Inhibitor molecules that interfere with GAP activity
Explanation:
The mitogen-activated protein kinase (MAPK) is a pathway composed of proteins that amplify and integrate signals from receptors localized on the surface of cells and trigger the transcription of specific genes in the nucleus of the cell. In eukaryotic organisms, the MAPK pathway is known to control critical cellular processes such as, for example, cell proliferation, cell differentiation, cell death, etc. RAS proteins are GTPases localized to the plasma membrane involved in MAPK signaling. Moreover, the GTPase activating proteins such as RasGAP (Ras GTPase activating protein) regulate Ras-GTP bound by promoting GTP hydrolysis. It has been shown that RasGAP expression is down-regulated in different types of cancer. In this regard, it has been proposed that the interference of GAP activity should result in an enhanced Ras protein activation in cancer cells, thereby initiating tumorigenesis by inducing, for example, uncontrolled cell proliferation.

11. The balanced chemical reaction is:
2 B(IO₃)₃ + 3 Fe₃P → 2 BF₃ + 3 Fe(IO₃)₂
12. In this case, the limiting reagent is the Iron (II) phosphide.
13. The amount of Iron (II) iodate produced is 1.825 moles.
14. The amount of excess Boron iodate remaining after the reaction is 0.265 moles.
15. The actual yield of the reaction is 132.1 g.
11. To write the balanced chemical reaction, we need to first determine the correct coefficients for each reactant and product. We can do this by balancing the number of atoms of each element on both sides of the equation.
12. The limiting reagent is the reactant that is used up first. In this case, the limiting reagent is the Iron (II) phosphide. This is because 112.0 g of Iron (II) phosphide is equivalent to 0.560 moles, which is less than the 1.825 moles of Boron iodate.
13. To calculate the amount of Iron (II) iodate produced, we need to multiply the number of moles of Boron iodate by the molar ratio between Boron iodate and Iron (II) iodate.
14. The amount of excess Boron iodate remaining after the reaction is 0.265 moles. This is because 1.825 moles of Boron iodate minus 0.560 moles of Iron (II) phosphide is equal to 0.265 moles.
The amount of excess Iron (II) phosphide remaining after the reaction is 56.0 g. This is because 0.560 moles of Iron (II) phosphide is equal to 56.0 g.
15. To calculate the actual yield of the reaction, we need to multiply the theoretical yield by the percentage yield.
The actual yield of the reaction is 132.1 g. This is because 1.825 moles of Boron iodate is equivalent to 132.1 g and the percentage yield is 72.659.

Why do daughter cells have DNA that is identical to the parent cell? Explain your answer.
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.

An S-shaped pattern formed when a stream flows through channels is called
Answer:
meander
Explanation:
A meander is a series of regular sinuous curves in the channel of a stream/river/watercourse, thereby forming a rounded or "S"-shaped bend curve. Meanders are common in alluvial areas that have low gradients, where they are formed by the dynamics of the watercourse. The meander belt is the zone within which a meandering watercourse occupies on its floodplain. The sinuosity is a measure to calculate the degree of meandering in the channel of a watercourse.
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.
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.

The mutation rate is the probability of a single gene mutating in an offspring bug.
a. True
b. False
Answer:
True
Explanation:
A mutation is any alteration in the genetic sequence of the genome of a particular organism. Mutations in the germline (i.e., gametes) can pass to the next generation, thereby these mutations can increase their frequency in the population if they are beneficial or 'adaptive' for the organism in the environment in which the organism lives (in this case, an insect/bug). The mutation rate can be defined as the probability of mutations in a single gene/locus/organism over time. Mutation rates are highly variable and they depend on the organism/cell that suffers the mutation (e.g., prokaryotic cells are more prone to suffer mutations compared to eukaryotic cells), type of mutations (e.g., point mutations, fragment deletions, etc), type of genetic sequence (e.g., mitochondrial DNA sequences are more prone to suffer mutations compared to nuclear DNA), type of cell (multicellular organisms), stage of development, etc. Thus, the mutation rate is the frequency by which a genetic sequence changes from the wild-type to a 'mutant' variant, which is often indicated as the number of mutations per round of replication, per gamete, per cell division, etc. In a single gene sequence, the mutation rate can be estimated as the number of de novo mutations per nucleotide per generation. For example, in humans, the mutation rate ranges from 10⁻⁴ to 10⁻⁶ per gene per generation.
