Answer:
0.0014; 0.0044
Explanation:
The absolute risk (AR) of a disease refers to the risk of developing the disease over a given time period. In this case, the absolute risk of the newborn African American child having sickle cell anemia is equal to 1 individual with the disease over 700 individuals >> AR = 1 / 700 = 0.0014. Moreover, the Relative Risk (RR) is calculated by comparing the likelihood of the absolute risk occurring between two distinct groups. In this case, the relative risk for the newborn African American having sickle cell anemia compared to a newborn European American child can be calculated by dividing the absolute risk of the newborn European American child with the measured absolute risk of the newborn African American child >> RR = 0.0000625 / 0.0014 = 0.0044.
All of the following factors contribute to the differences in complex trait risk predictions between different laboratories, EXCEPT ____________. differing methods of combining risk from multiple genetic variants selection of different genetic variants for risk determination different assessments of environmental factors genotyping of different variants
Answer:
different assessments of environmental factors
Explanation:
In humans, for predicting the future phenotype of any individual, the PSR is used.
A trait may be defined as the state of a character that is a distinct variation of the phenotypic characteristic of any organism.
The following factors contributes to the differences in the complex trait risk predictions in the different laboratories :
-- differing methods of the combining risk from the multiple genetic variants.
-- genotyping of the different variants.
-- selection of the different genetic variants for such risk determination.
Thus the factor which does not contribute is :
"different assessments of the environmental factors."

what must be true about two objects if heat is flowing between them
Answer:
The objects must be the same temperature.
Explanation:
if heat is flowing between two objects, so both the objects must have the same temperature because the heat in object 1 passes to the object 2 due to the conduction property present in these objects. The heat flows from one body to another body until both have the same amount of heat energy as well as temperature so that's why we can say that both objects must be the same temperature.

Answer:
A yellow lizard population living on an island with no predatorsA hawk was introduced to the habitat and starts preying on the yellow lizard because it is easier to see from the air Some of the lizards mutate their color from yellow to greyish brown so they can camouflageYellow individuals keep being hunted, while brown individuals get to survive The following generations of lizards will have a higher proportion of greyish brown individuals and just a few yellow individuals. Eventually, almost all of the lizards will be greyish brown individuals.Explanation:
The scenario is the following.
A population of yellow lizards lives on an island where there is no natural predator. Males of the species use the yellow color to attract females in reproductive seasons. The brighter the males are, the better their genetic quality is. Females are also yellow, but not as bright as males.
A new hawk species was introduced into the island to control some farm pests. But this hawk species prefer to feed on the lizards. The yellow color of these animals contrasts with the dark background and can be easily seen from the air. So the lizard population suffers from significant predation affecting its size sharply.
Some of the lizards then suffer from a mutation and change their color from yellow to greyish brown, which turns to be better to camouflage on the rocks and get to survive. Individuals with greyish brown color get to reproduce at a higher rate than yellow individuals, who keep being hunted by the hawk.
Eventually, after many generations, the yellow individuals decrease to near zero in the population, while greyish brown individuals increase significantly, with males still being brighter than females.
------------------------------------------------------------------------------------------------------
Natural selection is an evolutive force that can act favoring an allele or against it, according to how it affects the fitness of individuals. Natural selection selects beneficial alleles and increases their frequency in the population.
When many organisms in a population sharing the same trait die, it is because they did not have good fitness, so they were not adapted to the environment and its pressures. The alleles coding for that trait were not good for the fitness of the animals, so they do not get to survive.
These individuals die before reproducing, so they could not transfer their genetic charge to the following generation. Eventually, the alleles coding for the trait will decrease in the population, probably near zero. Natural selection is acting against this phenotype. Other alleles will be beneficiated, and their frequency in the population will increase.
This change in alleles frequency is what we call adaptation.
Natural selection results in adaptation, which means the increase of the aptitude phenotype. Aptitude is the contribution of each genotype to the next generation.
In many cases, adaptations can be correlated to environmental factors or selective pressures applied by other organisms or habitats.
Let us remember that a mutation is a change or alteration in DNI sequences that introduce new variants. Many of these are eliminated, but some of them might succeed and be incorporated into each individual. These mutations are the ones that have been selected by natural selection.
So, in the exposed example, we are focussing on the lizards population.
• The selective pressure or modeling environmental factor is predation by the introduced hawk.
• The lizards´ response to predation is the survival of only those that carry mutations ⇒ greyish brown color
• Natural selection benefits these mutations.
• Greyish brown lizards survive and increase their fitness.

3.Each onion plant begins as a single cell containing 16 chromosomes. How many chromosomes are present in each of the cells that you observed
Answer:
In somatic cells, 16 chromosomes are present whereas in sex cells, there is 8 chromosomes.
Explanation:
In the somatic cells, the replication of chromosomes occur and after the replication is completed, the parent cell is divided into two daughter cells having double number of chromosome by each daughter cell i.e. 16 chromosomes while on the other hand, in sex cells, first the parent cell divides into two daughter cells and after sometime, these daughter cells are again divided having total four daughter cells each receives half number of chromosomes i.e. 8 chromosomes.

You are out hiking and walk past a great outcrop of granite that is part of an exposed batholith. Looking closer you notice pieces of sandstone within the batholith. Which rock is OLDER, the granite or the sandstone?
Answer:
Sandstone is younger than the granite rocks
Explanation:
As the rocks layer found at the bottom are the oldest and closer to the ground surface are the younger. This is due to the law of superimposition and as when looking at the outcrops you will notice pieces of sandstone within the batholith that indicates that the base is formed by granite and is later cemented by sandstone rockUpon completion of seeding a flower and a vegetable, research and identify the optimum propagation conditions, such as, water and light demand, appropriate temperature, and, other elements that may affect the germination from seeding. Compare your research findings with your existing conditions. If any discrepancies found, address how you would like to mitigate. Describe the entire process in your weekly lab report journal. Add photos, sketches or other supplementary information, if necessary.
Answer:
Needs optimum environmental conditions.
Explanation:
Seedling, a flower and a vegetable needs suitable conditions for growth and development. All of the three stages of plant life cycle requires optimum water, fertilizers and light intensity in order to grow and develop at full speed. Seeds need a specific temperature in order to germinate. Most seeds germinate when the soil temperature is between 68 and 86 Fahrenheit. In the same way the plant also needs specific temperature for bearing flowers. All the stages requires optimum water in the soil for absorption.

5. Shawn has a hypothesis that fungicides harm bee development. Using what you now know, describe an experiment to test Shawn’s hypothesis. Be sure your response includes what data should be collected and how you would collect it.
Answer:
Yes.
Explanation:
Yes, the fungicides harm bee development by causing changes in behavior, immune health, and reproduction etc. For verifying this hypothesis, we have to take two environments, in one environment fungicides are applied to the plants while on the other environment, there is no fungicide applied to the plants. Th result shows that the bees are affected and act abnormal where fungicides are applied as compared to those bees which are normal in behaviour and other features.

We can also apply the equation for residence time to a single component of a fluid, such as carbon dioxide (CO2). Assume that the residence time of CO2 in the atmosphere is six years and the mass of CO2 in the atmosphere is 3 × 1015 kilograms. If these estimates are correct, what is the mass flow rate of CO2 into and out of the atmosphere? Assume the atmosphere is at steady state. Write your answer in scientific notation, and be sure to include the correct units.
Answer:
[tex]f=5*10^1^4kg/year[/tex]
Explanation:
[tex]T=m/f\\f=m/T\\f=\frac{3*10^1^5kg}{6 years}[/tex]
The mass flow rate of CO2 into and out of the atmosphere is [tex]f = 5 * 10^{14} kg/ year[/tex]
What is the method ?
[tex]T = m/f[/tex]
Therefore, [tex]f = m/ t[/tex]
[tex]f=3 * 10^{15} / 6 years[/tex]
