Answers

Answer 1

Answer:

1. unique to the PQ cycle:

Two electrons are transferred from the reduced carrier to plastocyanin

2. unique to the Q cycle:

Two electrons are transferred from the reduced carrier to cytochrome c

3. common in both PQ cycle and Q cycle:

- The cycle converts a two-electron transfer process into two one-electron transfer processes

- Addition of electrons one at a time generates a semiquinone intermediate

- Used to translocate protons across a membrane

Explanation:

The Q cycle (Q due to quinol) refers to the cycle by which electrons are transferred from ubiquinol to cytochrome c. This cycle is associated with the sequential mechanism of oxidation-reduction between ubiquinol and ubiquinone, also known as Coenzyme Q10 (CoQ10, used as electron carrier), in order to move protons across the inner mitochondrial membrane. In the first phase of the cycle, ubiquinol attaches onto the cytochrome c oxidoreductase, also called complex III (because this complex is the third complex in the electron transport chain), in order to transfer two electrons to the complex. On the other hand, the PQ cycle (PQ due to plastoquinone) refers to the cycle where plastoquinone transports electrons during light-dependent photosynthetic reactions. In the PQ cycle, the plastoquinone serves as an electron carrier through the membrane of the thylakoid. In the first step of this cycle, plastoquinone obtains two electrons from photosystem II and absorbs two protons from the chloroplast stroma, resulting in plastoquinol, which subsequently transfers electrons to plastocyanin in a process coupled with the generation of a proton gradient between the lumen of thylakoid discs and stroma.

The location for the SI gene is 3q26.1. What does this information tell you?

Answers

The SI gene provides instructions for producing the enzyme sucrase-isomaltase

Annotation 3q26.1. indicates a specific localization of a gene on chromosome number 3.

The localization of a gene in a chromosome is indicated by a specific pattern of bands generated by different cytogenetic staining techniques.

The first number/letter used in this code indicates the chromosome (in this case, 3 indicates chromosome number 3).

The letter q represents the long arm of the chromosome, whereas the shorter arm is referred to as p (in this case, 3q)

The following numbers represent the position of the gene on the chromosome arm, which is evidenced by specific patterns and staining techniques.

In conclusion, annotation 3q26.1. indicates a specific localization of a gene on a chromosome.

A track and field coach is trying to decide what beverage is the best pre-training beverage for athletes to drink before a daily training session. The coach has chosen three beverages: a soda, a Gatorade, and water for the athletes to drink before training. The coach will then collect data on their performance during the period of time while training.
Afterward, the coach will track the performance of the athletes over an eight week period to see how their performance has changed.


What is the best Hypothesis for the experiment above? Explain why that is the best Hypothesis.

Answers

Answer:

The correct answer is - "which beverage would help athletes the best if he takes it before a daily training session".

Explanation:

The coach is trying to decide which beverage is going to help best for the athletes before their training session. He tried soda, water, and Gatorade and compare the data he gets after his experiment.

According to his experiment, he wanted to find the best beverage that will help athletes best. For this, the best hypothesis would be "which beverage would help athletes the best if he takes it before a daily training session", as it provides the real idea of the experiment.

Answers

Answer:

All organisms must regulate gene expression by turning genes on and off different cells at different times. In prokaryotic cells, related genes may be organized into operons , which can be turned on and off as a single unit. Eukaryotes have more complex modes of control, including the packing of chromosomes, RNA slicing (which can produces several mRNAs from a single gene), and the control of translation.

An understanding of gene regulation mechanisms has led to several interesting and important applications. For example, the loss of gene regulation can result in cancer, or out-of-control cell growth. And reproductive cloning can produce new live individuals, while therapeutic cloning can produce potentially therapeutic stem cells.

Why is DNA locked in the nucleus of the cell?​

Answers

Answer:

Inside the nucleus lies the blueprint that dictates everything a cell will do and all of the products it will make. This information is stored within DNA. The nucleus sends “commands” to the cell via molecular messengers that translate the information from DNA.

Explanation:

Answer:

In organisms called eukaryotes, DNA is found inside a special area of the cell called the nucleus. Because the cell is very small, and because organisms have many DNA molecules per cell, each DNA molecule must be tightly packaged. ... Researchers refer to DNA found in the cell's nucleus as nuclear DNA.

It turned out that all the turkeys had eaten peanuts from Brazil. A fungus was growing on the peanuts. The fungus produced a dangerous poison called aflatoxin. Aflatoxins cause stomach pain, lung failure, cancer, and death in people and animals.

Farmers make a great effort to prevent fungi from growing on their stored crops. In a pile of grain or nuts, fungi have plenty of food and living space. The best way for farmers to prevent fungi from growing is to make sure there is not enough for fungi to survive and grow.

Anthropologists have been studying the role of soybean curd andrelated products in the culture of Hong Kong. The researchers interviewpeople about how frequently they eat soybean products, where they eatthem (at home or in restaurants), and during what time of day they eatthem. The researchers also ask people about how they preparesoybean products, where they obtain soybean products, and any beliefsthey might have about soybean products (such as their nutritionalvalue). The data are used to assess the role of soybean products in theculture. The researchers are also considering how their findings relateto global soybean consumption patterns.

Answers

Answer:

1.) Cultural Anthropology

2.) Biological Anthropology

3.) The research  could be used to compare quinoa consumption in other parts of the world.

Explanation:

Anthropology is a scientific field that studies humans. It studies humans all over the world with respect to their behaviors and cultures in both past and present eras. Anthropology is divided into four major types: Cultural, Biological, Linguistic and archaeological.

1.) Because this research is towards the role of soybean and related products in Hing Kong, we can confidently say that it falls under the cultural aspect of anthropology which focuses on the study of differences in cultures among humans.

2.) Considering the fact that the research deals with a biological product (soybean) that has effects on humans, then biological anthropology is the most closely related field.

3.) The researchers intend to relate their findings from this research to global soybean and other related products consumption pattern. Therefore, this research could be used to compare quinoa consumption in other parts of the world.
