Use the numbers 1, 2, 3, 4, and 5 to place the protein creation steps below in the correct order. Ribosome attaches to the mRNA.

Information is transcribed in DNA to mRNA. tRNA anticodon carries an amino acid that compliments the mRNA codon. mRNA leaves the nucleus. The chain of amino acids forms a protein.

Answer: The correct sequence for the protein creation is as follows-

1) Information is transcribed in DNA to mRNA.

2) mRNA leaves the nucleus.

3) Ribosome attaches to the mRNA.

4)  tRNA anticodon carries an amino acid that compliments the mRNA codon.

5) The chain of amino acids forms a protein.

According to the Central Dogma, the genetic information is transferred from DNA to mRNA to Proteins.

The first step is transcription in which DNA is converted to mRNA with the help of enzyme RNA polymerase. In eukaryotic cells, this process occurs in the nucleus.

This is followed by translation, which takes place in the cytoplasm when mRNA leaves the nucleus.

Ribosomes are the specialized organelles, which act as the site for protein synthesis ( translation).

Ribosomes attach to the mRNA. tRNA brings amino acid, which has anticodon complementary to the codon present in the mRNA. A chain of amino acids is thus synthesized, which is called Protein.

Round seeds and yellow seed color are dominant to wrinkled seeds and green seed color. What is the probability of having offspri
adoni [48]

Answer:

<h2>The probability of a cross between RRYY x RrYy to generate a yellow and wrinkled seed offspring is 0%.</h2>

Explanation:

Circular and yellow seeds are overwhelming and wrinkled and green seeds are passive. It is vital to keep in mind that resective characteristics are as it were displayed when the sibling has two passive alleles for those characteristic, in the event that the descendant includes a latent allele and a overwhelming allele, the characteristic that will be presented is the overwhelming one. For this reason, able to say that a cross between RRYY x RrYy plants, would not create any descendant with wrinkled and yellow seeds. Typically since, the descendant of a crossing, must show an allele of each parent. One parent as it were has overwhelming alleles (RRYY), so able to say that all descendant will get 1 overwhelming allele for color and a overwhelming allele for seed surface, anticipating the sibling from communicating latent characteristics.

According the law of Inertia _____.
kobusy [5.1K]

Answer:

Law of inertia, also known as Newton’s first law of motion states that An object will continue to be in the state of rest or in a state of motion unless an external force acts on it. We have read about the Aristotle fallacy, as per which an external force is always required to keep a body in motion.

Explanation:

Galileo’s Free Fall Experiment

The most accepted theory of motion in Western philosophy, prior to the Renaissance, was the Aristotelian theory which stated that “In the absence of external power, all objects would come to rest that moving objects only continue to move so long as there is a power inducing them to do so. ” Despite its general acceptance, the Aristotelian theory was discredited by several notable philosophers. Later, Galileo refined the theory of inertia.

How did Galileo Explain Inertia?

Galileo hypothesized that a falling object gains an equal amount of velocity in equal intervals of time. This also means that the speed increases at a constant rate as it falls. But, there was a problem in testing this hypothesis: it was impossible for Galileo to observe the object’s free-falling motion and at the time, technology was unable to record such high speeds. As a result, Galileo attempted to decelerate its motion by replacing the falling object with a ball rolling down an inclined plane. Since free-falling is basically equivalent to a completely vertical ramp, he assumed that a ball rolling down a ramp would speed up in the exact same way as a falling ball would.

Using a water clock, Galileo measured the time it took for the rolling ball to reach a known distance down the inclined plane. After several trials, it was observed that the time it took for the ball to roll the entire length of the ramp was equal to double the amount of time it took for the same ball to only roll a quarter of the distance. In short, if you were to double the amount of distance the ball traveled, it would travel four times as far. Through this experiment, Galileo concluded that

If an object is released from rest and gains speed at a steady rate (as it would in free-fall or when rolling down an inclined plane), then the total distance, s, traveled by the object is proportional to the time squared needed for that travel.

PUNTOS POSIB!
Sindrei [870]

Aim

When dividing the world into zoogeographical regions, Alfred Russel Wallace stipulated a set of criteria by which regions should be determined, foremost the use of generic rather than species distributions. Yet, recent updates of Wallace's scheme have not followed his reasoning, probably explaining in part the discrepancies found. Using a recently developed quantitative method, we evaluated the world's zoogeographical regions following his criteria as closely as possible.

Location

Global.

Methods

We subjected presence–absence data from range maps of birds, mammals and amphibians to an innovative clustering algorithm, affinity propagation. We used genera as our taxonomic rank, although species and familial ranks were also assessed, to evaluate how divergence from Wallace's criteria influences the results. We also accepted Wallace's argument that bats and migratory birds should be excluded (although he was contradictory about the birds) and devised a procedure to determine the optimal number of regions to eliminate subjectivity in delimiting the number of regions.

Results

Regions attained using genera (eight for mammals and birds and six for amphibians) strongly coincided with the regions proposed by Wallace. The regions for amphibians were nearly identical to Wallace's scheme, whereas we obtained two new ‘regions’ for mammals and two for birds that largely coincide with Wallace's subregions. As argued by Wallace, there are strong reasons not to consider these as being equivalent to the six main regions. Species distributions generated many small regions related to contemporary climate and vegetation patterns, whereas at the familial rank regions were very broad. The differences between our generic maps and Wallace's all involve areas which he identified as being uncertain in his regionalization.

Main conclusions

Despite more than 135 years of additional knowledge of distributions, the shuffling of generic concepts, and the development of computers and complex analytical techniques, Wallace's zoogeographical regions appear to be no less valid than they were when he proposed them. Recent studies re‐evaluating Wallace's scheme should not be considered updates as such because they have not followed Wallace's reasoning, and all computer‐based analyses, including this one, are subject to the vagaries of the particular methods used.
