Answer:

It is a series of processes for waters because it break down organic substances in water so that it will not result or cause pollution when water is released into the environment.

Explanation:

Bio remediation is a natural process in which microorganisms is use to clean and treat contaminated water, soil and surface. This process ensure the growth of microorganisms that feed on the contaminants present in the such contaminated media. It can be use to kill oil souls and other contaminated media. It is use as series of process in water so as to break down organic substances or contaminants in water so that it will not cause pollution when the water is released.

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.

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.

Correct answer choice is:

d.  Erosion caused by hurricanes can leave coasts more exposed to storms.

Explanation:

Important erosion, rapture, and removal of solids happen through storms. Beach erosion is a typical consequence of the high waves that transpire when hurricanes pass onto land. The decline of sand makes the beach to grow narrower and deeper in elevation. Storm loops take the sand offshore, keeping and depositing the sediment in great sandbars.

Explanation:

The deer population decreasing will most likely affect a population of deer.

This can be defined as the number of organisms in a given area over a period of time.

Winter season is characterized by unavailability of plants for grazing due to the harsh weather condition which will lead to starvation and a decrease in the deer population.

A long, cold winter is likely to decrease the population of deer due to reduced food availability and increased stress and mortality rates.

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.

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.

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.

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.

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
