Answer:
They use different detecting methods to assess neuronal circuits
Explanation:
Chemogenetics is a technique widely used in neuroscience research to explore signaling interactions by means of genetically modified receptors capable of interacting with small molecules. Chemogenetics was first used to determine the function of the chalcone isomerase gene by inducing mutations that altered its substrate specificity. On the other hand, optogenetics is a bioluminescence-driven genetic technique used to control genetically modified neurons that express light-gated ion channel genes. This technique is also used to monitor neuronal networks. In consequence, optogenetic and chemogenetic techniques have recently been combined in order to analyze neuronal circuits, it by analyzing the same actuator molecule.

2. Do you feel that government agencies, like the USDA, promote eating an animal-based diet? Why or why not?
3. Given this "sudden epidemic" of obesity in America within the last 30 years, do you feel the main cause of our "growing nation" is due to an animal-based diet, increased consumption of processed foods and refined sugars, or a decline in physical activity?
4. Do you feel the success of the patients was due to a) the increased amount of fruits/vegetables and plants or b) the elimination of meats or c) a combination of both? Why? Use information we've learned in class to justify your answer.
5. What part of the movie really stood out to you (good or bad) and why? Be very specific. This is where you show me you paid attention to the entire documentary.
Answer:
1. Yes
2. No
3. Yes
Explanation:
Yes, the elimination of the animal based foods decreases and reduce chronic diseases in many developed countries such as US and England etc. but meat is also very necessary for animal diet due to the presence of high protein content.
No, USDA does not promote the intake of an animal-based diet. this agency promote the intake of nutritious food in a limited amount so it does not cause any disease. They recommend the eating of Grains, Fruits, Protein, Foods, Vegetables and Dairy products in a limited amount.
Yes, the main cause of obesity in Americans is due to two reasons, first cause is the intake of meat in large amount and second cause is the decline in physical activity.
The success of the patients was due to combined effect of increased amount of fruits/vegetables and plants and the elimination of meats. By using these two element the patient will quickly recovered.

Herceptin cancer fighting antibodies cannot be produced through genetic engineering of bacteria. What is used instead to accomplish this? A. Selecting cells that produce a large amount of Herceptin to reproduce over generations B. Genetically engineered mammalian cells C. Genetically engineered Bacteriophages D. Producing them with chemicals instead of inside cells
Answer:
B. Genetically engineered mammalian cells
Explanation:
Herceptin is a monoclonal antibody that binds (attach) to specific antigens in cancer cells to destroy them. This antibody is used in the treatment of different types of cancers including breast and gastric carcinoma, in which HER2/neu protein is overexpressed. Herceptin targets HER2/neu receptors present in cancer cells to kill them. HER2/neu is a protein signaling receptor involved in cell proliferation, thereby this antibody works to selectively target cells that have an excess of HER2/neu receptors such as gastric and breast cancer cells.

Use the following information to answer the question below.
Two true-breeding stocks of pea plants are crossed. One parent has red, axial flowers and the other has white, terminal flowers; all F1 individuals have red, axial flowers. The genes for flower colour and location assort independently.
If 1000 F2 offspring resulted from the cross, approximately how many of them would you expect to have red, terminal flowers?
Answer:
750
Explanation:
With the f1 generation all being red flowers we can conclude that Red is dominant (R) and white is recessive (r).
This leads to the f1 generation having Rr. If you breed two Rr together you get
1 RR
2 Rr
1 rr
75% of the f2 will have red flowers. So if you take 1000 and multiply it by .75 you will get 750
Approximately 750 flowers will be Red.

1) What must occur for a strand of double-helix DNA before it can transcribe itself into RNA is the DNA must unwind its double- helix near the gene that is going to be transcribed. This region that the DNA has opened up is called transcription bubble.
2) The two key differences between DNA and RNA is that DNA contains sugar deoxyribose, while RNA contains sugar ribose. The second key difference is DNA's nitrogen bases are adenine, cytosine, guanine and thymine ( A, C, G, T ) while in RNA instead of thymine there is the uracil base.
( A, C, G, U )
3) The reason DNA transcribes itself into RNA because that is the whole goal of the process called transcription where a strand of DNA is copied into a new molecule of mRNA ( messenger RNA ) to to construct a functional product such as a protein.
4) A error during the process of transcription can change how the organism's physical characteristics or also can impact the way how DNA codes the phenotype. The name that was given for this situation is called a Mutation.

Desribe the structure of amino acids including what makes amino acids different from each other
Answer:
1) Amino acid contains a central carbon atom attached to: an anime group, carboxyl group, hydrogen atom and a side chain
2) The side chain of each amino acid differentiates from one another
Please find the description below
Explanation:
Amino acids are monomeric chemical compounds that forms the make up of a protein. Amino acids , like every other chemical compound, have a structure. Amino acids have two functional groups i.e. amine group (-NH2) and carboxylic acid group (-COOH).
All amino acids, which are naturally 20 in number have basic parts in common namely: 1) a central carbon atom, also called the alpha carbon 2) a hydrogen atom 3) an amine group i.e. (-NH2) 4) a carboxyll group i.e. (-COOH)
These are the basic parts of all amino acids, however, the difference between the amino acids is found in the series of different atoms called Side chains or R group that attach to the alpha carbon. These R group makes each amino acid specific and different. For example, a side chain containing sulphur (CH3-S-(CH2)2) is the R group of methionine. Each amino acid has a different side chain attached to the basic structure listed above.
Come up with your own story of a trophic cascade, describing how the organisms occupying the different trophic levels would be affected
Answer:
The leafhoppers eat plant tissues and, at the same time, they are eaten by spiders that are the food of large lizards. Finally, these lizards are the food of birds that are eaten by snakes.
Explanation:
The food chain starts with primary producers such as plants and algae (i.e., level 1), then goes through herbivorous species including insects and fish (level 2) and finally ends with carnivores such as rodents, snakes and hedgehogs (levels 3, 4 and sometimes 5, which depends on presence of larger predators). Thus, the trophic levels are represented by the number of steps of the food chain. In an ecosystem, the organisms can also be classified according to the mode of obtaining the food in producers (autotrophs), consumers (heterotrophs) and reducers (detritivores).

When curare, a South American arrow poison, is placed on a nerve-muscle preparation, the muscle though a neurotransmitter is still being released from the nerve. Give a possible explanation for the action of curare (be sure to include specific details explaining does not contract when the nerve is stimulated, even how and why).
Answer:
In a muscle contraction,neurotransmitter acetycholine stimulate the post synaptic membrane of the neuron or the sarcolemma of the muscles cells at the motor end plate .This neurotransmission effect leads to the opening of ligand gated sodium channels.
Therefore action potential(Endplate potential) is transmitted across the synaptic juction to to the muscles to bring about contraction of muscles(effector) .Therefore Acetycholine is refereed to as excitatory hormone.
Curare works as competitive inhibitor of acetycholine at the motor end plate. It prevents the binding of Acetycholine with the endplate.Therefore, ligand gated Na+channels can not open, thus End potential can not be generated due to lack of depolarization, thus contraction of muscles is inhibited.
Thus,despite the fact that the neurotransmitter is produced, the curare has blocked the end plate.So, no muscles contraction will occur because ,no place for the the excitatory acetylcholine to bind with.Hence the the muscle cells are in the permanent state of relaxation (resting membrane potential).
Animals poisoned with this substance usually asphyxiate because of paralysis of the diaphragm, external and internal inter-coastal muscles and collapse of the lungs and therefore failure of the entire respiration muscles and system.Thus lack of oxygen from failed breathing.

Phytoplankton, shown on the left in the image below, are microscopic organisms that can be found in freshwater and salt water environments. They perform photosynthesis to get energy and act as an important food source for larger organisms, such as the whale that is shown on the right. Phytoplankton A large whale. Which characteristic describes the whale but not its food source, the phytoplankton? The whale is heterotrophic. The whale has cell walls. The whale is unicellular. The whale is a prokaryote.
Answer:
The whale is heterotrophic.
Explanation:
All living organisms require energy for their life processes. In nature, this energy source is obtained by feeding on one another. When one organism eats another, it gets energy. In this case, a large whale is described to be reliant on a photosynthetic phytoplankton for its energy source.
The phytoplankton is capable of producing its own energy source (food) via the process of photosynthesis. Hence, making it an autotrophic organism. However, since the large whale is dependent on the phytoplankton for food/energy source, it is regarded to be heterotrophic i.e. incapable of producing its own food, hence, depends on other organism like phytoplankton in this case.
