Scientists take scientific measurements carefully in order to ensure their reliability and validity. What is the difference between accuracy and precision in scientific measurements?
a.
Accuracy is how far out the measurement is taken, while precision is how close a measured value is to its true value.
b.
Accuracy is how close a measured value is to its true value, while precision is how close measured values are to each other.
c.
Accuracy is how close a measured value is to its true value, while precision is how close the average value is to the true value.
d.
Accuracy and precision are two different words for the same thing.

Answers

Answer 1

The difference between accuracy and precision in scientific measurements is as follows: Accuracy is how close a measured value is to its true value, while precision is how close measured values are to each other (option B).

What is accuracy and precision?

Accuracy is the exact conformity to truth, or to a rule or model i.e. the degree of conformity of a measure to a true or standard value.

On the other hand, precision is the ability of a measurement to be reproduced consistently.

Accuracy and precision are two measures of observational error. Accuracy is how close a given set of measurements are to their true or standard value, while precision is how close the measurements are to each other.

Explanation:

This is because incomplete dorminance is a type of inheritance pattern in which a dorminant allele does not completely masked the effect of recessive allele. The recessive allele is expressed little and the dorminant. Example is the nose size. The allele for big nose and recessive allele for small nose are not completely dorminant.

The order of the genes on a plant chromosome is A, B, C, where A and B are located 10 cM apart and B and C are located 3 cM apart. What is the probability that the trihybrid ABC/abc will produce any kind of recombinant gamete

Answers

Answer:

Double Crossing-over prob = 0.3% Simple Crossing-Over prob A-B = 9.7%Simple Crossing-Over prob B-C = 2.7%Total Crossing-Over prob = 12.7%

Explanation:

Available data:  

order of the genes on a plant chromosome is A, B, CA and B are located 10 cM apartB and C are located 3 cM apart

The genetic distance = recombination frequency x 100 expressed in map units (MU). One centiMorgan (cM) equals one map unit (MU).

We can use the provided map with the distances between genes to predict the occurrence of any kind of recombinant gamete.  

We know that there is a probability of a simple crossing over to occur between genes A and B, or between genes B and C. And we also know that there is a probability of double crossing-over occurrence.

We can get the probability of the double-crossing over by multiplying the recombination frequencies between A-B and B-C. So,

DCO prob = recombination frequency A-B x recombination frequency B-C

                 = 0.1  x  0.03 = 0.003 = 0.3%

DCO prob = 0.3%

According to this, we would expect to find

0.15% AbC0.15% aBc

Now we need to know what are the probabilities of getting a simple crossing-over, SCO. We already have the genetic distances between genes. 10 cM equals 0.1 of recombination frequency, and 3cM equals 0.03 of recombination frequency. However, we can not estimate the probabilities of simple crossing over using only this information, because this data is including the probabilities of the double crossing-over occurrence. So we need to substrate this percentage.    

SCO prob A-B = 0.1 - 0.003 = 0.097 = 9.7%

SCO prob A-B = 9.7%

we would expect to find

4.85% Abc4.85% aBC

SCO prob B-C = 0.03 - 0.003 = 0.027 = 2.7%

SCO prob B-C = 2.7%

we would expect to find

1.35% ABc1.35% abC

The total Crossing-over probability, TCO, is then the sum of all the crossing over probabilities,

TCO= SCO A-B + SCO B-C + DCO

TCO prob = 9.7% + 2.7% + 0.3%

TCO = 12.7%

1. What is a biogeochemical cycle?
2. What drives, or powers, the water cycle?
3. What causes water to condense and form clouds?

Answers

Answer:

1. In ecology and Earth science, a biogeochemical  cycle or substance turnover or cycling of substances is a pathway by which a chemical substance moves through biotic and abiotic compartments of Earth.

2. The sun, which drives the water cycle, heats water in the oceans. Some of it evaporates as vapor into the air. Rising vapor cools and condenses into clouds.

3. Heated by sunshine, the ground heats the air just above it. That warmed air starts to rise because, when warm, it is lighter and less dense than the air around it. As it rises, its pressure and temperature drop causing water vapor to condense. ... The air cools as it rises, and eventually clouds form.

As atmospheric CO2 increases, the amount of CO2 dissolved in seawater is expected to increase as well. This produces more carbonic acid, which then dissociates into hydrogen ions and something else.

Describe the difference between gene mutations and chromosomal mutations, including:

- What are they?

- How do they occur, including their types?

- When will they result in a change in the phenotype of offspring?

Answers

Explanation:

Genetic alternations include chromosomal abnormalities and gene mutations. Chromosomal abnormalities generally arise during cell division. ... Gene mutations are permanent changes in DNA gene sequence. They can arise during normal DNA replication or in response to environmental factors.

Answer:

When a gene mutation occurs, the nucleotides are in the wrong order which means the coded instructions are wrong and faulty proteins are made or control switches are changed. The body can't function as it should. Mutations can be inherited from one or both parents. They are present in the egg and/ or sperm cells.

What type of mutation can affect offspring?

The only mutations that matter to large-scale evolution are those that can be passed on to offspring. These occur in reproductive cells like eggs and sperm and are called germ line mutations. No change occurs in phenotype. Some mutations don't have any noticeable effect on the phenotype of an organism.

Your mother asked you to put water soluble fertilizer around the roots of her prize winning rose bush. The following week, you noticed the leaves of her rose bush are beginning to turn yellow and wilt. In terms of tonicity and water movement, explain why the rose began to die after the addition of fertilizer. Bonus: What can you do to solve this problem

Answers

Answer/Explanation:

The water soluble fertilizer that was added created a hypertonic environment. Concentration of solute is higher around the plant cells thereby leading to the movement of water molecule away from the cells of the rose bush. This is why the rise bush began to wilt as the leaves turn yellow.

Solution:

Give the plants a reasonable amount of water to cause the solution to be isotonic. When the amount of fertilizer and water is relatively balanced, the plants would be able to utilize the fertilizer, feed well and grow well.
