Which statement best describes the limits of science?
Answers
Answer:
Science cannot answer philosophical answers.
Answer:
No scientific theory can ever be proven true.
Physics has two tremendously good theories: Einstein’s Theory of Relativity, and Quantum Field Theory.
These have been around for about a century and no contradictions have shown them to be false.
And yet these theories contradict each other, so one or both will eventually be supplanted.
Explanation:
Science is based upon evidence. And no matter how much evidence you have for a theory, it is impossible to say it is true.
Thus, truth is beyond what science if capable of.

A graph with a calibration curve, linear regression and extrapolation was drawn up from your lab results. What were the two types of data that were being compared on the graph? (In other words what was on the X and Y axis) What does this graph tell you about the water sample you collected?
Answers
Answer:
X is the concentration of the substance being measured and Y is the response from the instrument that is being used to measure
Explanation:
A calibration curve is the plot of known concentration of substances where x is the increasing known concentration and Y is the response, typically "absorption" taken from the instrument that is used for measuring. This curve is then used to find out the concentration of the unknown substance by using it's absorbance and comparing it with the calibration curve. For example:
Concentrations and absorbance readings are as follows
0.5mg/mL=10 nm
1.0mg/mL=15nm
1.5mg/mL=20nm
2.0mg/mL=25nm
This data is plotted on a calibration curve. Next we measure the unknown substance the absorption is 20nm. We can suggest that the concentration is 1.5 mg/mL. If there are readings that fall inbetwen values then the formulat to calculate the right concentration would be y = mx + b, where m is the slope and b is the y-intercept.
Linear regression uses the modification of the slope formula y= a + bx to best see how the data of the water samples would fit on the slope of the calibration curve. X is the independent variable , b is the slope of the line and a is the y-intercept.
Extrapolation would be the action of calculating data that are outside the calibration curve, assuming the trend would continue.

Assume that three loci, each with two alleles (A and a, B and b, C and c), determine the differences in height between two homozygous strains of a plant. These genes are additive and equal in their effects on plant height. One strain (aa bb cc) is 10 cm in height. The other strain (AA BB CC) is 22 cm in height. The two strains are crossed, and the resulting F1 are interbred to produce F2 progeny. Give the phenotypes and the expected proportions of the F2 progeny.
Answers
Explanation:
In the given question, the trihybrid cross has been provided for the height trait and it is provided that recessive alleles (aabbcc) contribute 10 cm whereas dominant allele (AABBCC) contribute 22cm.
The height contributed by each dominant allele (A+A+B+B+C+C)= 22cm
The height contributed by each recessive allele (a+a+b+b+c+c)= 10 cm
The dominant genotype is 12 cm taller than recessive genotype which indicates that dominant allele contributes 2 cm.
In trihybrid cross-64 genotype will be formed with these dominant allele based on which the height of the plant will be determined.
The genotype with dominant allele (Height) and F2 progeny are
0 (10cm) - 1/64
1 (12cm)- 6/64
2 (14cm)- 15/64
3 (16 cm)- 20/64
4 (18cm)- 15/64
5 (20 cm)- 6/64
6 (22 cm)- 1/64
Answer:
Given,
aabbcc = 10 cm
AABBCC = 22 cm
The genes are additive which means that each dominant allele will contribute to the overall height. The base minimum height is 10 cm (no dominant allele) and the maximum height is 22 cm (all six dominant alleles). Thus, six dominant alleles contribute 12 cm of height to the base height, which means that each dominant allele adds 2 cm of height.
When, aabbcc X AABBCC :
AaBbCc ( F1 )
When, AaBbCc X AaBbCc :
7 types of phenotype is possible. They are:
6 dominant alleles = 22 cm
5 dominant alleles = 20 cm
4 dominant alleles = 18 cm
3 dominant alleles = 16 cm
2 dominant alleles = 14 cm
1 dominant allele = 12 cm
0 dominant allele = 10 cm
They will be in the ratio = 1 : 6 : 15 : 20 : 15 : 6 : 1 as given by the ratio of additive effect governing three loci. The intermediate phenotype ( 16 cm ) will be maximum in number and the numbers will decrease as we move to the extremes.

If a plant has a genotype Rr, what is the probability it will produce a gamete that’s is R?
A) 25%
B) 50%
C) 0%
D) 100%
Answers
Answer:
B 50percent I think
Explanation:
correct me if I'm not sure
If a plant has a genotype of Rr, then the probability that it will produce a gamete that is R is 50%, which is present in option B. 50% represents the R, and the remaining 50% represents the r.
What are the gametes?The gametes are the products of the cells that undergo meiosis, and by the law of segregation, the alleles can segregate and the gametes are formed by the law of independent assortment. The alleles in this case are the R and r that are present on the chromosomes, and according to the segregation rule, half of the cells get the R allele and the other half get the r type of allele.
Hence, if a plant has a genotype of Rr, then the probability that it will produce a gamete that is R is 50%, which is present in option B. 50% represents the R, and the remaining 50% represents the r.

A long, cold winter is likely to decrease the population of deer due to reduced food availability and increased stress and mortality rates.
Why cold winter affects deer population?A long, cold winter is likely to have a negative effect on the population of deer. This is because during a long, cold winter, the availability of food for deer can become scarce, especially if the winter is severe and there is a lot of snow on the ground. The snow can make it difficult for deer to access their food sources, such as grasses and shrubs. This can lead to malnutrition and starvation in some individuals, which can cause a decline in the population.
Additionally, a long, cold winter can also affect the reproductive success of deer. If the winter is too harsh, it can cause stress and illness in pregnant does, leading to fewer fawns being born in the spring. This can also contribute to a decline in the deer population.

There are two species of freshwater shrimp that are introduced to a pond. The first species, Caridina cantonensis, is brightly colored with red and white stripes. The second species, Caridina multidentata, is more mottled drab in coloration. Fish have an easier time finding and eating Caridina cantonensis due to their bright colors. When each of these species reproduce they produce about 100 offspring, but only 30% Caridina cantonensis offspring survive to reproductive age, while 75% Caridina multidentata offspring survive to reproductive age.
A. In this situation what is natural selection selecting for?
B. In this situation what is natural selection selecting against?
C. How do you predict this population will evolve?
D. Identify how each of the listed conditions from the above scenario that influence natural selection. Population must have variation. Some variations are favorable More offspring are produced than survive Those that survive have favorable traits Differential reproductive success

Answer:
A. Colour of the freshwater shrimp
B. Predator fish problem
C. Based on the number of offsprings that has survived
D. Differential reproductive success
Explanation:
A. The freshwater shrimp species C. cantonensis is brightly coloured which is easy to find by fish whereas C. multidentata is mottled drab in colour which can hide in the environment. Therefore the natural selection will select for the mottled drab of the shrimp.
B. The mottled drab colour of the shrimp will be selected against the predator species which feeds on the shrimp population as the predator species can find the brightly coloured species easily but the mottled drab colour will not be found.
C. The population is evolving can be identified based on the number of population found in that area as 75% of C. multidentata species reach reproductive stage while only 30% of C. cantonensis reach the reproductive rate.
D. The condition will be known as Differential reproductive success.

An object is located 8 cm away from a convex lens. The image is 24 cm away from the lens on the other side. What is the focal length of the lens?
A. 4 cm
B. 6 cm
C. 16 cm
D. 32 cm
Answers
Answer: B. 6 cm
Explanation:
First we take down the information given to us,
distance from the lens to the image (v) = 24cm
distance from the original object to the lens (u) = 8cm
So using the formula
1/u + 1/v = 1/f
Where f is the focal length
So we just input our information
1/8 + 1/24 = 1/f
Therefore;
3/24 + 1/24 = 1/f
4/24 = 1/f
1/6 = 1/f
f = 6
Our focal length = 6cm
