How can katey and amanda's amino acid sequence be the same and yet they may have a differences in their DNA?

Answers

Answer: Two people can have different DNA sequences but these sequences can code for the same amino acids due to the redundancy of the genetic code in which two different codons can code for the same amino acid.

Explanation:

The genome of an organism is found in a molecule called DNA (deoxyribonucleic acid). The main function of this DNA molecule is the long-term storage of information to build other components of cells, such as proteins and RNA molecules (ribonucleic acid); and the portion of the genome that codes for a protein or RNA is known as a gene. These protein-coding genes are composed of trinucleotide units called codons, each of which codes for an amino acid. For a protein whose sequence is encoded in the nucleotides of DNA to be synthesized, that DNA molecule must first be transcribed into a molecule called messenger RNA, and this molecule is used for a process called translation or protein synthesis. The sequence of the genetic material is composed of four distinct nitrogenous bases, which are represented by letters in the genetic code:

Adenine (A)Thymine (T)Guanine (G) Cytosine (C)Uracil (U) instead of T in RNA

The genetic code is the set of rules that defines how a sequence of nucleotides in RNA is translated into a sequence of amino acids in a protein. This code is common to all living things, which shows that it has had a unique origin and is universal. So, the code defines the relationship between each sequence of three nucleotides (codon) and each amino acid.  The number of possible codons is 64, of which 61 code for amino acids (one of them being the start codon, AUG) and the remaining three are stop sites (UAA, UAG, UGA). The codon sequence determines the amino acid sequence in a particular protein, which will have a specific structure and function.

However, the genetic code has redundancy but no ambiguity. For example, two different codon can code for the same amino acid, and the differences between codons encoding the same amino acid have differences in the third position. This is explained by the wobble effect, where the same anticodon (present in the transfer RNA that loads with the amino acid and interacts with the codon in the messenger RNA) can establish interaction with different codons, which differ in their third base. This is why, in general, tolerance to change at this position is greater than at the first and second positions, and therefore tends to be less represented in the case of variations that result in pathologies.

Thus, two people can have different DNA sequences but these sequences can code for the same amino acids due to the redundancy of the genetic code in which two different codons can code for the same amino acid.

Why are vestigial structures not removed by natural selection?

Answers

Structures that have no apparent function and appear to be residual parts from a past ancestor are called vestigial structures. Examples of vestigial structures include the human appendix, the pelvic bone of a snake, and the wings of flightless birds.

In which sealed container would the organisms be able to continuously cycle O2 and CO2 gases? A. A terrarium with a plant and a snail B. An aquarium with fish and plastic plants C. A terrarium with tadpoles and a pool of water D. An aquarium with rocks and snails

Answers

Answer:

A terrarium with a plant and a snail

Explanation:

This is because snail uses oxygen for cellular respiration and releases carbondioxide as by product.

Where as plants uses carbondioxide exhaled for photosynthesis in the presence of light energy and chlorophyll with water to produce glucose and oxygen. Therefore cycle if oxygen and carbondioxide gases is continuous.

People with antisocial personality disorder are often more difficult to treat than people with other types of personality disorders. Why do you think this is so?

Answers

Answer:

I think that the difficulty in dealing with a person suffering from antisocial personality disorder is due to their lack of remorse towards the bad things they can do, things that possibly exceed the ethics or judgment of the person who is going to treat them. In addition, their lack of discernment towards what is really right or wrong can cause serious confrontations or discord between the person who suffers from the disorder and others.

Explanation:

The antisocial personality disorder consists of the lack of understanding of good and evil, with which, the person can come to commit bad things without any remorse and even seeming something normal, which is why their dealings with a person who has an ethic Iron could be very complicated, unlike other disorders where the person may do bad things, but they are aware of the bad things they do and, therefore, they regret it and they could try a change in their behavior.

Compensation Point

Compensation Point for Light (of photosynthetic plants) is the intensity of light at which the rate of carbon dioxide uptake (photosynthesis) is exactly balanced by the rate of carbon dioxide production (respiration) or equivalently, the light intensity at which the rate of oxygen production is exactly balanced by the rate of oxygen consumption.

Explain how abiotic factors can have influence on the survival for individuals through natural selection.

Answers

Selection: Organisms live within ecosystems, which are made up of various biotic and abiotic factors. These factors contribute to selecting which variations provide the individual with an increased chance of surviving. ... Examples of abiotic factors include temperature, shelter, sunlight, water and nutrients.

Answer:

Biotic and abiotic factors are the environmental conditions that the organisms have to face to live in a specified environment.

Abiotic factors

Abiotic factors are the physical and chemical conditions of an environment. For example : heat, salinity, pressure, light, wind, pH ...

Biotic factors

Biotic factors are all the biological conditions of an environment for a specie/taxa. It can include prey and predator abundance, available food amount, available space, intra and interspecific competition...

The development of organims is under the control of abiotic factors. Some are adapted to heat, cold etc ... The abiotic factors will define which organisms are able or not to live in a specified place.

The living organisms will constitute the biotic factors, which define if and how can an organism live in a specified environment.

So, the abiotic factors are controling the biotic factors of an environment.
