A patient is admitted to your emergency room because of uncontrollable flailing arms. After a quick test, you determine the cell membranes in their arm nerves are damaged, and the cells aren’t signaling properly. Which type of protein needs to be repaired?

Answers

Answer 1
Answer:

Answer:

A patient is admitted to the emergency room because of uncontrollable flailing arms.After a quick test we determine the cell membranes in their arm nerves are damaged and the cells are not signalling properly. They are endoplasmic proteins.

Explanation:

The endoplasmic reticulum have many functions including the folding of proteins in many sacs called cisternae and the transport of synthesized proteins in vesicle to Golgi apparatus. RER is made up of cisternae, tubules and vesicles.The cisternae are made up of flattened membrane discs which are involved in the modification of proteins.The main function of smooth endoplasmic reticulum is to make cellular products like hormones and lipids.The type of RNA that contains the information for making protein is called messenger RNA or mRNA because it carries the information or message from DNA out of the nucleus into the cytoplasm.Through the process of transcription and translation the information from the genes is used to make proteins.

Well if endoplasmic reticulum stops working there would be many enzymatic processes  which would not occur ultimately leading to the death of many cells. Example of protein deficiency is kwashiorkor.Symptoms include fatty liver, flaky skin,diarrhoea, apathy ,failure to grow,edema of belly and legs.This edema is explained by the action of lipoxygenase on arachidonic acid to form leucotrienes and the normal functioning of proteins in fluid balance and lipoprotein transports. Dietary sources of proteins are milk, meats and eggs.Soy and quinoa are vegetable sources of complete proteins.Combining red beans or lentils with wholegrain rice or peanut butter with wholemeal bread also provides complete protein.

How doe vertical farming work

Answers

Vertical farming is exactly what it sounds like: a way of farming on vertical surfaces rather than traditional, horizontal farming. By using vertically stacked layers, farmers can produce a great deal more food on the same amount of land.

Polydactyly is a rare autosomal dominant trait that is 80% penetrant. What is the chance that a child born to an affected father and a normal mother will have the disorder

Answers

The question is incomplete, below is the complete question.

Polydactyly is a rare autosomal dominant trait that is 80% penetrant. What is the chance that a child born to an affected father and a normal mother will have the disorder?

Assume the paternal grandfather is normal.

I will use P to encode polydactyl as it is dominant and use p allele to encode normal phenotype

P= Polydactyl

p= Normal

From what is given in the question,the paternal grandfather is normal and that means that the father of the child receives one wild type allele from the paternal grandfather, however,the father is affected with the disease,hence the genotype is A a but the mother being normal will have the genotype of aa.

That is Parents;

Father Aa × Mother aa

Gametes a a A Aa ( P ) Aa ( P )

a aa ( p ) aa ( p )

So if it is 100% penetrant, that implies that the chances of the affected child is;

(2/4 ) ×100=50%

However, only 80% penetrant is given here,so that is why the chances of the affected is then ; (50/100) ×(80/100) ×100= 40%

That means the affected child chances are 40%.

Final answer:

Polydactyly is a rare autosomal dominant trait with 80% penetrance.

Explanation:

Polydactyly is a rare autosomal dominant trait that is 80% penetrant. This means that if a person carries the genetic mutation for polydactyly, there is an 80% chance that they will express the trait. Therefore, if the father is affected by polydactyly (carries the gene) and the mother is normal (does not carry the gene), each child they have has a 50% chance of inheriting the gene from the father and a 50% chance of inheriting the normal gene from the mother.

However, if a child inherits the gene for polydactyly from the father, there is an 80% chance that they will express the trait, meaning they will have the disorder. On the other hand, if the child inherits the normal gene from the mother, they will not have the disorder.

Most cells cannot harness heat to perform work becausea. heat does not involve a transfer of energy.
b. cells do not have much thermal energy; they are relatively cool.
c. temperature is usually uniform throughout a cell.
d. heat can never be used to do work.

Answers

Answer:

Temperature is usually uniform throughout a cell (Ans. C)

Explanation:

Heat or thermal energy is a kinetic energy. That is connected with the random movements present in the atoms. Temperature is usually uniform throughout the cell so the most cell can not harness heat to perform work.

Heat is a type of energy which is transfer from one body to another body due to the temperature difference.

It can only perform work if it is transferred from one source which is warmer to a body which is cooler. The temperature in living organisms is usually kept very constant due to the process of homeostasis.

Final answer:

Most cells cannot harness heat to do work because temperatures within the cell are typically uniform, so there's no heat gradient for work to be conducted. Heat tends to be lost instead.

Explanation:

Most cells are not able to harness heat to perform work because heat energy is often dissipated as waste during biochemical reactions. The correct option is c. The temperature is usually uniform throughout a cell. This means that there isn't a high temperature gradient in the cell, which would be needed in order for heat to be used for work. For heat to be harnessed and used for work, there must be a temperature difference because work is done when heat flows from a hotter area to a cooler one. Without a temperature gradient, heat energy cannot be used to perform work within a cell and is instead lost to the surrounding environment.

Many cities suffer from serious air and noise pollution—as well as endless traffic jams—because of too many cars. Some people feel that cities with extensive public transportation systems should ban passenger cars and force people to walk, bike, or use public transportation. Do you think this is a good idea? Why or why not?

Answers

Answer: I do think its a good idea cause it lessens pollution in the air we breathe in and stops us from burning fossil fuels

Explanation:

Final answer:

Banning passenger cars and promoting public transportation in cities is a good idea for reducing pollution and traffic congestion.

Explanation:

I believe that banning passenger cars and promoting the use of public transportation in cities is a good idea. This approach can help reduce air and noise pollution, alleviate traffic congestion, and improve overall quality of life. By encouraging people to walk, bike, or use public transportation, cities can create a more sustainable and livable environment for their residents.

One example of a city that has successfully implemented this approach is Copenhagen, Denmark. The city has an extensive public transportation system, including a well-connected network of bike lanes. As a result, more than 60% of residents commute by bike or public transportation. This has significantly reduced air pollution and traffic congestion in the city.

Additionally, adopting this approach can have numerous benefits, such as promoting physical activity, reducing carbon emissions, and improving public health. Overall, I believe that cities with comprehensive public transportation systems should consider implementing policies that restrict the use of passenger cars in order to create a cleaner, more sustainable urban environment.
