A teacher asks her students to find the average mass of a chicken egg. Each student is provided a carton of a dozen eggs and is

asked to create his or her own procedure for finding the average mass. Felicia chooses an egg that appears to be of average size. She places the egg on a balance and records its mass as the average. Darren finds the individual mass of one of his eggs and records it. He repeats the procedure for each of the 12 eggs. He lists all of the masses in order from smallest to largest and then records the most commonly appearing mass as the average. Colin finds the individual masses of all of his eggs. He also asks his classmates for the individual masses of their eggs. He adds the masses of all of the eggs in the classroom and divides by the total number of eggs measured. He records this mass as the average. Ella places all 12 of her eggs on a balance at the same time. She divides the total mass by twelve and records it as the average. Whose procedure is likely to produce the most accurate result?

If you have all the eggs weighed at different times and then write them down, after that add all of the number together. Divide the number by the amount of eggs. BOOM ANSWER!

Answer:

Collin's procedure will likely produce the most accurate result

Explanation:

The number of trials done in any lab or scientific investigation helps to reduce the uncertainty in the result or divide the uncertainty proportionally.

Here, Darren among all the students has taken 12 trials for 12 eggs individually while Felicia just picked one egg of average size based on her guess analysis. Collin on the other hand sum up the individual masses of all eggs in the classroom and then takes the average of it. Ella put all 12 eggs at once , finds a combined weight of them and then divides it by 12.

Now, since Collin has taken the maximum number of samples (as he has taken weight of individual eggs of all his class mates), therefore his result will give more accurate result.

Goshia [24]

Answer:

A. the two genes on chromosome 1 are more than 50 mu apart.

Explanation:

Two or more genes present on the same chromosomes are the linked genes. Linked genes do not assort independently and do not exhibit crossing over. Therefore, the linkage of genes results in deviations from Mendel's law of independent assortment. However, if the linked genes are present far from each other on the same chromosome, they may exhibit crossing over.

The greater the distance between the linked genes, the higher are the chances of crossing over. Crossing over of linked genes would result in some of the progeny to have the new gene combinations as it occurs during an independent assortment of two genes. Therefore, Mendel observed an independent assortment of two genes present together on chromosome 1 since they were present far apart from each other (more than 50 mu apart).

Describe the major differences in acute versus passive range of motion (rom) when distinguishing between an articular and nonart
Ierofanga [76]
The question should be about active vs passive range of motion.

In the active range of motion, the test is done by asking the patient to move their body themselves. In this case, the patient should use their muscle to move their body. If there is a restriction in this examination, it could be caused by the muscles or the joints, or the nervous system that used to contract the muscle.
In the passive range of motion, the test is done by the examiner moving the patient body. Since no muscle used, the test shouldn't be influenced much by the muscle. Then, if there is an articular joint issue, the restriction would be found in both passive and active ROM, but the nonarticular joint issue might only cause abnormality in the active ROM.

Which of the Caulerpa taxifolia’s traits make it so dangerous to local ecosystem
k0ka [10]

<u>Answer:</u>

<em>Caurepa taxifolia is an invasive species of algae and is listed in the IUCN list of 100 invasive species. </em>

<u>Explanation:</u>

In is an algae usually found in the pacific ocean. It was earlier used in aquariums as  an <em>ornamental species of algae</em>. The dangerously invasive nature overshadows its attractive appearance.

It is inedible and  increases in numbers at a surprisingly <em>accelerated rate.</em>  The growth of other plants is difficult in areas dominated by the Caurepa taxifolia. The introduction of this <em>algae was in the Meditteranian sea. </em>

Umnica [9.8K]

Answer:

Genetic mapping for unequivocal identification of the potentially causative mutation  

Explanation:

Galactosemia is a genetic disorder caused by mutations in the Galactose-1-phosphate uridylyltransferase (GALT) gene, which encodes an enzyme involved in the metabolism of galactose. Gene mapping is a technique widely used in genetics to identify the position of one locus a chromosome by using molecular markers to estimate genetic distances. Genetic mapping provides useful evidence in order to identify when a disease that is transmitted from parent to offspring can be associated with one or more genes and then determine which gene/s is/are responsible for this condition.
