How might global climate change effect iguana populations?
Answer:
Since iguanas are cold blooded animals and can not regulate their own body temperatures, once temperatures reach 40° they become immobilized and they cant move, so if it is cold they will die.
which of the following best describes how the potential is affected by the structural change in the gene?
Answer:
A gene mutation is a permanent alteration in the DNA sequence that makes up a gene, such that the sequence differs from what is found in most people. Mutations range in size; they can affect anywhere from a single DNA building block (base pair) to a large segment of a chromosome that includes multiple genes.

The difference between PCR and real-time PCR is thatA. real-time PCR can measure the amount of DNA amplified as the reaction proceeds, while standard PCR cannot.B. real-time PCR can amplify DNA a billion-fold within just a few hours, while standard PCR cannot.C. real-time PCR can determine the DNA sequence, while standard PCR cannot.D. real-time PCR uses DNA polymerase, while standard PCR does not.
Answer:
The correct answer is A. real-time PCR can measure the amount of DNA amplified as the reaction proceeds, while standard PCR cannot.
Explanation:
PCR (Polymerase Chain Reaction) is a molecular biology technique. Conventional PCR and real-time PCR are diferent types of PCR, and are both used to exponentially amplify DNA molecules. In both types, a polimerase enzyme is employed to sinthesize DNA copies. The main difference is that conventional PCR is qualitative whereas real-time PCR is quantitative. So, real-time PCR permits not only to detect and amplify DNA but also permits to perform a quantification of the target DNA. This is accomplished by measuring a fluorescence signal - which is directly the amount of DNA amplified- during the course of the reaction.

Answer:
1. It's difficult to find out if someone is blood doping because the body has red blood cells. First the doctors get blood samples. Because the body constantly produces new blood, the blood that was stored shows that it is old with the blood samples it shows that there are some new and some old blood cells, which is how you can tell if they are doping.
2. Hemoglobin is a protein that is produced by the body that carries oxygen in the red blood cells the more red blood cells the more hemoglobin you have. Ex; If the athletes have a high level of hemoglobin on the day of the race than it had been days or weeks before, to shows that the athlete was blood doping.
3. It can help the body produce more blood cells to carry more oxygen (get more energy) and the body can get used to that kind of high altitudes and climates. Which leads to you getting even more energy at lower altitude levels.
Why do people, animals, and all other organisms do cellular respiration?

The unit states that any animal that can be domesticated probably already has been. Explain the logic behind the statement and whether or not you find it convincing.
Answer:
Saying that if an animal can be domesticated that it probably already has been is saying that a lot of things are documented and if it has the capability to be domesticated or brought under human control then someone somewhere probably has. So I would personally find this convincing.

All fish reproduce sexually, but fertilization may occur in one of two ways.
In__________
fertilization, the female fish releases eggs in the water or on a surface. The male fish spreads
sperm over the eggs to fertilize them.
In__________
fertilization, the eggs are fertilized inside the female's body. The young develop there until the
female gives birth.
exExplanation: external internal
Hello, 3Coli here!
Here is your answer:
In external fertilization, the female fish releases eggs in the water or on a surface. The male fish spreads sperm over the eggs to fertilize them.
In internal fertilization, the eggs are fertilized inside the female's body. The young develop there until the female gives birth.

What effect does dietary protein have on the body?
Answer:
Even mostly or entirely plant-based diets can be high in protein. Protein is an essential part of a healthy diet. It helps to build and repair muscle, organs, and bones. High-protein diets have also been shown to be helpful with reducing fat, losing weight, increasing satiety, or a feeling of fullness, and retaining muscle.

Answer:
rRNA - Ribosomal RNA, a molecular component of a ribosome, the cell's essential protein factory. Strictly speaking, ribosomal RNA (rRNA) does not make proteins. It makes polypeptides (assemblies of amino acids) that go to make up proteins
tRNA - Transfer ribonucleic acid (tRNA) is a type of RNA molecule that helps decode a messenger RNA (mRNA) sequence into a protein. tRNAs function at specific sites in the ribosome during translation, which is a process that synthesizes a protein from an mRNA molecule.

What is an essential characteristic of members of a given species?
the ability to produce eggs or live offspring without sexual reproduction
the ability to reproduce with members of another species
the ability to reproduce with one another and have fertile offspring
the ability to reproduce with organisms outside of their local gene pool
Answer:
the ability to reproduce with one another and have fertile offspring.
Explanation:
An essential characteristic of the members of a given species is the ability to reproduce with one another and have fertile offspring. Thus, the correct option is C.
What are the characteristics of a species?A species is a group of organisms which are living in an area with similar characteristics which are capable of exchanging genes and chromosomes and produce new organism similar to itself. The species are important as it maintains the equilibrium in the ecosystem.
A species can be defined as the largest group of organisms with the two individuals of the appropriate sexes can produce a fertile offspring, typically through sexual reproduction. The species can also be defined on the basis of their karyotype, DNA sequence, morphology, behavior or ecological niche.
Therefore, the correct option is C.

3.We anticipate our recombinant DHFR protein to be functional for use in future research applications. However, if you had been able to test functionality and found that your recombinant GST-DHFR-His protein was not functional, what would you propose is one potential issue you would investigate to troubleshoot further. In other words, what is one thing that could have gone wrong to result in non- functional protein from the method used and results obtained this semester
Answer:
In the given case, the protein would have required to go through the process of post-translational modification, however, the mentioned protein would have been cultured in the prokaryotic system, the process of post-translational modification would have failed to take place. This step would be essential for the functionality of the protein. Thus, there is a need to culture it within the eukaryotic system.
The covalent and generally the enzymatic modification of proteins post its biosynthesis is termed as post-translational modification.
