Parkinson’s disease is a brain disorder that may be caused by mutations in several genes that code for the production of alpha-synuclein. Individuals who have Parkinson’s disease exhibit symptoms such as uncontrollable tremors, difficulty walking, and loss of coordination. How might geneticists determine where the mutations that cause Parkinson’s disease are located? PCR analysis gene mapping DNA fingerprinting STR analysis
Answer:
They could use SNPs(Single nucleotide polymorphisms) of DNA, which are an anaylysis of chromosomes using high tech laser magnification. This SNPing allows scientist to more closely view specific genes in chromosomes that cause certain traits. It allows for a greater genetic mapping and could also be used to see mutations, if you know which chromosome to look at.

The image shows the skulls of three different organisms. The foramen magnum position is the hole in the skull where the spinal nerve cord passes through. Based on the structure of the skulls, which two statements can you infer?
Complete question: The image shows the skulls of three different organisms. The foramen magnum position is the hole in the skull where the spinal nerve cord passes through. Based on the structure of the skulls, which two statements can you infer?
a) All three organisms share a common evolutionary lineage
b) Wolves do not share any common ancestors with humans and chimpanzees.
c) Humans likely share more common ancestors with chimpanzees than they do with wolves.
d) Chimpanzees share more common ancestors with wolves than they do with humans.
Note: The skull figures are shown in the attached file
Answer:
a) All three organisms share a common evolutionary lineage
c) Humans likely share more common ancestors with chimpanzees than they do with wolves.
Explanation:
Although controversial, there is a theory that states that the foramen magnum is associated with bipedalism and human beings´ evolution. According to different studies, the foramen magnum moved from the posterior part of the skull to a central and ventral position. This displacement occurred as mammals began to move in two legs - bipedalism-.
When comparing different mammals skulls it seems evident that bipedalism and foramen magnum position and orientation are highly related. Although all mammals have a common ancestor, the foramen magnum of bipeds mammal organisms is located more anteriorly and ventral than the foramen magnum of the quadrupeds mammals.
In the exposed example, when comparing these three skulls, the two statements that might be inferred are:
a) All three organisms share a common evolutionary lineage. This is true because they are all mammals, and as a group, they share a common ancestor in evolution.
c) Humans likely share more common ancestors with chimpanzees than they do with wolves. This is true because by analyzing the foramen position, we can see that both the chimpanzee and the human´s foramen is located on the ventral side of the skull. Chimpanzees´ hole is more posteriorly and humans´ hole is more anteriorly or centrally located, but in both cases, they are in ventral position. Wolves´ hole, on the other hand, is located posteriorly. As we said before, Although all mammals have a common ancestor, the foramen magnum of bipeds mammal organisms is located more anteriorly and ventral than the foramen magnum of the quadrupeds mammals. And groups closer to human beings (in this case is chimpanzee) show their foramen magnum in a similar place than those mammal groups that are further in evolution (wolves).

Why is ATP important in the metabolism or organisms? a. It hydolyzes to add free energy to exergonic reactions. b.The terminal phosphate bond has higher energy than the other two phosphate bonds. c. The terminal phosphate is held by a strong covalent bond that when hydrolizes, captures free energy. d. ATP provides energy coupling between exorgonic and endergenic reations
Answer:
ATP provides energy coupling between exergonic and endergonic reactions.
Explanation:
Adenosine triphosphate is an important molecule found in the cells and its role is to transport energy that is necessary for the cell or metabolic activities. These activities include muscle contraction and nerve impulse propagation. The ATP provides energy to both the energy consumption actions and energy-releasing reactions and thus needs a small amount of input of energy. The chemical bonds on breaking provide energy for cells to work.Two fruit flies that are heterozygous for body color and eye color are crossed. Brown body color is dominant to black body color.

Read the passage: Genetically Engineered Corn. Then 1. Explain what Bt corn is and how it is made. 2. Describe the benefits of Bt corn. 3. Describe the risks of Bt corn. 4. Make an argument for or against the use of Bt corn and provide support for your position.
1. Bt maize is a genetically modified maize. It is produced through biochemical techniques and with the use of biotechnology that allows genes of Bacillus thuringiensis bacteria to be introduced in the DNA of corn. These genes allow Bt maize plants to produce a toxic protein specific to certain groups of insects.
2. With the production of this protein, Bt corn becomes immune to attack by these insects. As a result, the use of pesticides in the corn crop is reduced, which makes production healthier and avoids side effects on the soil. In addition, it prevents the production of corn from falling due to the attack of insects.
3. Among the disadvantages, we can say that Bt maize does not control all the pests that attack maize, only a few, which allows maize to be attacked. It can also trigger evolution in pest species that are immune, creating a toxin-resistant species. Finally, it can create contamination in wild maize crops (that is, those that have not been genetically modified), ending diversity.
4. I believe that the use of Bt corn is favorable. This is because it allows a greater production of food to meet our need and increasingly intense demand for food. However, it is necessary to affirm that the use of this corn needs regulation and inspection, mainly in the big industries that can harm the small producer.

Which is a result of a seasonal change (meaning a change that happens over
and over at a certain time of year)?
A. Plankton dying due to an oil spill
B. Frogs digging into mud to hibernate in the winter
C. Grass dying due to overgrazing
D. Fish moving away from a polluted site and into cleaner water
Answer:
b
Explanation:
the winter is a season
The answer is B. Frogs digging into mud to hibernate in the winter is a seasonal change that happens every year as temperatures drop in the winter.
What can be with case of planktons ?Plankton dying due to an oil spill, grass dying due to overgrazing, and fish moving away from a polluted site and into cleaner water are not necessarily tied to seasonal changes, but can occur due to other factors such as pollution, climate change, or human activities.
A seasonal change is a natural occurrence that happens regularly and predictably during certain times of the year. These changes are often triggered by shifts in the amount of sunlight, temperature, and precipitation that occur as the Earth moves through its annual orbit around the sun.
Some common examples of seasonal changes include the arrival of spring flowers, the turning of leaves in the fall, and the migration of birds in the winter.
In the case of frogs digging into mud to hibernate in the winter, this is a natural response to the colder temperatures that occur during the winter months.
As temperatures drop, frogs begin to slow down and their metabolism slows, causing them to seek out shelter and protection from the cold. By digging into the mud, they are able to protect themselves from freezing temperatures and other harsh winter conditions.
In contrast, the other examples given - plankton dying due to an oil spill, grass dying due to overgrazing, and fish moving away from a polluted site and into cleaner water - are not necessarily tied to seasonal changes.
These events can occur at any time of year and are often caused by human activities such as pollution, climate change, and overuse of natural resources.
While these events may have a significant impact on the environment, they do not represent the natural, predictable seasonal changes that occur as part of the Earth's natural cycles.

Answer:
Frogs reproducesexually and when organisisms reproduce sexually there are benefits which include:
produces genetic variation in the offspring.
the species can adapt to new environments due to variation, which gives them a survival advantage.
a disease is less likely to affect all the individuals in a population.
A disadvantage is that sexual reproduction takes longer than asexual reproduction. A mate must be found, the egg must be fertilised by sperm, and then the offspring develop. The benefit of introducing genetic variation into the species , however, outweighs this disadvantage.
Answer:
Frogs reproduce sexually: they require sperm from a male and an egg from a female to produce offspring. This type of reproduction allows for greater genetic variation. But organisms that sexually reproduce need to reach sexual maturity before they can reproduce. They also use energy to find a mate.
