While you and your classmate are studying for your biological anthropology midterm, your classmate tells you that the bones of Lucy, a famous australopithecine specimen that dates to about 3.2 million years ago, were dated based on carbon-14 analysis. Why is this incorrect?

Answers

Answer 1

The options for this incomplete question are :

Fossils are living organisms that have wholly or partially been transformed into rock.

Lucy does not have bones with organic material necessary for carbon-14 dating.

This specimen is also far too old for C-14 dating to be accurate, as well as for any other technique but palaeomagnetic dating.

Your classmate is therefore incorrect for all of the reasons listed. (All of the above)

Answer:

The correct answer is - all of the above reasons.

Explanation:

Fossils are living life forms that have completely or mostly been changed into the rock during the process of fossilization. Lucy doesn't have bones with organic material that are essential to use the carbon 14 dating technique.

This example is additionally very old for C-14 dating to be exact, just as for some other method, however, palaeomagnetic dating can do the job of dating in this case.

Thus, the correct answer is - all of the above reasons.

Determine whether the given procedure results in a binomial distribution​ (or a distribution that can be treated as​ binomial). If the procedure is not​ binomial, identify at least one requirement that is not satisfied. The YSORT method of gender​ selection, developed by the Genetics​ & IVF​ Institute, was designed to increase the likelihood that a baby will be a boy. When 150 couples use the YSORT method and give birth to 150 ​babies, the genders of the babies are recorded. Does the procedure represent a binomial​ distribution? A. ​No, because there are more than two categories for each trial. B. ​No, because the trials of the procedure are not independent. C. ​Yes, because the procedure satisfies all the criteria for a binomial distribution. D. ​No, because the probability of success differs from trial to trial.

Answers

Answer:

The correct answer is  C)

Explanation:

The number of couples who used YSORT method  (x) =  150That is, the number of couples who used YSORT method is limited or defined or definite.The probability of giving birth to a boy, for each couple is 1/2 or 0.5The gender of the baby born in each case mutually exclusive (Independent)

We can conclude that the procedure results in a binomial distribution because the assumptions of the binomial distribution are met.

A football hits the ground and an apple hangs from a tree.
Which statement is correct?
Both football and apple have kinetic energy.
Both football and apple have potential energy.
The football has potential energy and the apple has kinetic energy.
The football has kinetic energy and the apple has potential energy.

Answers

Answer:

The football has kinetic energy and the apple has potential energy.

Explanation:

Potential energy is the energy of an object at rest. Because the apple is hanging from a tree, it is not moving. Therefore, it has potential energy.

Kinetic energy is the energy of an object in motion. Because the football is moving from being in the air to hitting the ground, it has kinetic energy. When it hits the ground, the kinetic energy gets transferred into the ground.

Hope this helps.

Answer:

Yes, the Clements successional theory been subjected to peer review and publication.

What is  Clements successional theory?

Plant succession was characterised by Clements as a developmental process that, during the course of a community, it went through a well-defined series of stages that, in the end, resulted in a mature community, also known as the climax community. The climatic conditions that determined the climax community's existence manifested themselves in the form of an indicator and an expression of that community.

His hypothesis of community formation, sometimes known as plant succession, is what brought Clements the most fame. Even after World War II, Clements' organicism and physiological perspective were still around, albeit in a watered-down version, despite the fact that it was extensively discredited by later ecologists.

The number of chromosomes during meiosis is incredibly important.why is that?

Answers

Meiosis is important because it ensures that all organisms produced via sexual reproduction contain the correct number of chromosomes, Meiosis also produces genetic variation by way of the process of recombination.

I hope this helps you

Meiosis refers to the process by which a single cell divides twice to produce four haploid daughter cells. These are the gametes, which are sperms in males and eggs in females.

Why the number of chromosomes is important during meiosis?

Meiosis is a eukaryotic cell division process.  However, the genetic material distributed among the resulting daughter cells is distributed in very different ways by these two processes.

Mitosis results in the formation of two identical daughter cells, each with the same number of chromosomes as the parent cell.

Meiosis, on the other hand, produces four distinct daughter cells, each with half the number of chromosomes as the parent cell.

Because meiosis generates cells that will become gametes (or reproductive cells), this reduction in chromosome number is critical; without it, the union of two gametes during fertilization would result in offspring with twice the normal number of chromosomes.

Thus, we can conclude that the number of chromosomes during meiosis is incredibly important because It allows gametes to have half the original number of chromosomes of the organism.

The fuel for nuclear power plants comes from

Answers

Answer:

Most nuclear reactors are fueled with a compound known as uranium dioxide. This uranium dioxide is put together in a fuel assembly and inserted into the nuclear reactor—where it can stay for several months or up to a few years. While in the reactor the fuel undergoes nuclear fission and releases energy

Explanation:

Answer:

Uranium is the most widely used fuel by nuclear power plants for nuclear fission. Nuclear power plants use a certain type of uranium—U-235—as fuel because its atoms are easily split apart. Although uranium is about 100 times more common than silver, U-235 is relatively rare at just over 0.7% of natural uranium.

Some viruses can be crystallized and their structures analyzed. One such virus is yellow mottle virus, which infects beans. This virus has a single-stranded RNA genome containing about 6300 nucleotides. Its capsid is 25-30 nm in diameter and contains 180 identical capsomeres.If the yellow mottle virus begins its infection of a cell by using its genome as mRNA, which of the following would you expect to be able to measure?
A) replication rate
B) transcription rate
C) translation rate
D) formation of new transcription factors

Answers

The correct answer is 9 proteins form each of the 20 facets of this virus. A capsid is the protein shell that surrounds a virus. A capsomere is the subunit of the capsid. Depending on the virus, capsomeres arrange in many different shapes to form the capsid. The yellow mottle virus has 20 facets, this means that it has an icosahedral capsid. Since it contains 180 identical capsomeres, we can conclude that 9 proteins form each facet.

He was standing up straight enough now; dressed in a smart blue uniform with gold buttons, the sort worn by the employees at the banking institute; above the high, stiff collar of the coat his strong double-chin emerged; under the bushy eyebrows, his piercing, dark eyes looked out fresh and alert; his normally unkempt white hair was combed down painfully close to his scalp. He took his cap, with its gold monogram from, probably, some bank, and threw it in an arc right across the room onto the sofa, put his hands in his trouser pockets, pushing back the bottom of his long uniform coat, and, with look of determination, walked towards Gregor. He probably did not even know himself what he had in mind, but nonetheless lifted his feet unusually high. Gregor was amazed at the enormous size of the soles of his boots, but wasted no time with that he knew full well, right from the first day of his new life, that his father thought it necessary to always be extremely strict with him. And so he ran up to his father, stopped when his father stopped, scurried forwards again when he moved, even slightly. In this way they went round the room several times without anything decisive happening, without even giving the impression of a chase as everything went so slowly. Gregor remained all this time on the floor, largely because he feared his father might see it as especially provoking if he fled onto the wall or ceiling. Whatever he did, Gregor had to admit that he certainly would not be able to keep up this running about for long, as for each step his father took he had to carry out countless movements. He became noticeably short of breath, even in his earlier life his lungs had not been very reliable. Now, as he lurched about in his efforts to muster all the strength he could for running he could hardly keep his eyes open; his thoughts became too slow for him to think of any other way of saving himself than running; he almost forgot that the walls were there for him to use although, here, they were concealed behind carefully carved furniture full of notches and protrusions then, right beside him, lightly tossed, something flew down and rolled in front of him. It was an apple; then another one immediately flew at him; Gregor froze in shock; there was no longer any point in running as his father had decided to bombard him. He had filled his pockets with fruit from the bowl on the sideboard and now, without even taking the time for careful aim, threw one apple after another. These little, red apples rolled about on the floor, knocking into each other as if they had electric motors. An apple thrown without much force glanced against Gregor's back and slid off without doing any harm. Another one however, immediately following it, hit squarely and lodged in his back; Gregor wanted to drag himself away, as if he could remove the surprising, the incredible pain by changing his position; but he felt as if nailed to the spot and spread himself out, all his senses in confusion. The last thing he saw was the door of his room being pulled open, his sister was screaming, his mother ran out in front of her in her blouse (as his sister had taken off some of her clothes after she had fainted to make it easier for her to breathe), she ran to his father, her skirts unfastened and sliding one after another to the ground, stumbling over the skirts she pushed herself to his father, her arms around him, uniting herself with him totally now Gregor lost his ability to see anything her hands behind his father's head begging him to spare Gregor's life. A. Gregor's father appears more businesslike to Gregor. B. Gregor notices a difference in his father, after which the father attacks and injures Gregor. C.
