Flicker-fusion is the ability to distinguish many seperate flashes of light simultaneously. How do most flying insects compare to humans and why?
Answer:
Flicker fusion is the ability to distinguish many separate flashes of light simultaneously.
Flying inscets and humans, both have the ability of flicker fusion and it provides them to give a better visual of a fast-moving objects. Though humans have less flicker fusion threshold than insects.
They both can change their flicker fusion threshold as a function of viewing stimulus size, distance, luminance, intensity, achromatic vs. chromatic, and retinal location.

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.

kidney.
A pancreas
B urethra
C kidney
D gall bladder
Answer:
C. Kidney
Explanation:
The kidney is a vital organ in the human body. It is bean shaped and helps in the filtration of toxic substances and wastes from the body fluids which is then reabsorbed into the bloodstream.
The kidney also controls the level of water, pH and sodium levels. It however controls the blood pH by excretion of hydrogen ions and forming bicarbonate which ensures the blood pH is within its optimal and normal range.
Answer:
kidneys
Explanation:
The kidneys are the body's filtration system, and are responsible for filtering out the fluids in the body. The biproduct of this is called urine and is removed from the body
Please help me come up with an answer for this question thankyou so much! Compare and contrast the processes of cellular respiration and photosynthesis. Think of as many similarities and differences as you can (things to consider: inputs and outputs, the role of energy, the types of organisms that do each process, the location within cells)
Explanation:
The end result is glucose, with oxygen being the waste product. The two processes are similar in that they both produce energy, albeit in two different forms. They are different in that photosynthesis assembles the glucose molecule, while cellular respiration takes it apart.

5. Provide the corresponding RNA strand that would
segment of DNA: ATTCGCACT
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.
5) DN: ATTCGCACT -----------> RNA: AUUCGCACU

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.

Explanation:
Pedigrees are used to help geneticists understand how traits are inherited between generations. The Romanovs, a Russian royal family, had a history of hemophilia, a sex-linked disorder that is determined by a recessive allele on the X chromosome.
A genetic pedigree is shown. Irene is a carrier. Her husband is not a carrier. Her children Waldemar and Henry have hemophilia.
What is the best evidence to prove that Irene was heterozygous for hemophilia?
Alice carried the recessive allele.
Alexandra carried the recessive allele.
Frederick carried the recessive allele.
Waldemar carried the recessive allele.
Answer:
Waldemar carried the recessive allele.
Explanation:
The carrier is the individual that has the affected allele or mutation but does not express the trait, or might express it in different levels. Although, as the person carries the mutation, she or he might transmit the genetic mutation associated with a disease to the progeny. In general, these diseases are inherited as recessive traits.
So, in the exposed example we know that:
hemophilia is a sex-linked disorderhemophilia is determined by a recessive allele on the X chromosome.Irene is a carrier.Her husband is not a carrier.Her children Waldemar and Henry have hemophilia.If Irene is a carrier, this means that she is heterozygous and that her genotype is X⁺X⁻ (Being the symbol + the dominant allele, and - the recessive one for that expresses the trait)
The fact that Irene´s husband is not a carrier means that his genotype is X⁺Y
Their boys Waldemar and Henry have hemophilia, so both their genotypes are X⁻Y
The best evidence to prove that Irene was heterozygous for hemophilia is that Alice carried the recessive allele.
Alice is Irene´s Mother, and she is a carrier as well. Irene´s father, Louis, is not a carrier, so she could have inherited a dominant allele from her father and a recessive allele from her mother, X⁺X⁻, or she could have inherited two dominant alleles from both her parents X⁺X⁺. This is not proof enough of Irene being heterozygous. The fact that Alexandra, Irene´s sister, was also a carrier does not say anything about Irene´s genotype, because they could both share the same genotype or not. This is not proof of Irene being heterozygous.Frederick (her brother) was hemophilic. He received a recessive allele from Alice, but this does not say anything about Irene´s genotype. The fact that Waldemar (her son) was hemophilic, is the best evidence to prove that Irene was heterozygous for hemophilia. Walderman received the Y chromosome from his father and an X chromosome from his mother. The X chromosome that he received from his mother carried the recessive allele for the trait, and this is why he had hemophilia. This means that there is no best evidence for Irene´s genotype than her son´s genotype.

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.

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.

What type of transport occurs in the cell membrane when a person does sports and is consuming alcohol?
Cellular transport: it is the exchange of substances through the plasma membrane, which is a semipermeable membrane. Transport routes are through the cell membrane
It allows the metabolism waste to be expelled from its interior It allows the movement of substances that it synthesizes as hormones. Metabolic energy: is the way in which it acquires nutrients through processes of incorporation into the cell of nutrients dissolved in water.
Therefore, when the person consumes alcohol in excess the ce transport is part of the disincorporation of toxic waste, while when the person does sports, and is supposed to have a balanced diet, the cellular transport uses it for his metabolic energy.
