emphysema and asthma are respiratory disorders that may both be attributed to smoking; they also share many symptoms in common. As a physician, how would you distinguish between these two disorders when diagnosing a patient? explain.

Answers

Answer 1

Emphysema happens when the tiny sacs in your lungs (called alveoli) are damaged. Chronic bronchitis is when the tubes that carry air to your lungs (bronchial tubes) get inflamed. Smoking is the most common cause of those conditions (and COPD).

Some people have asthma and COPD at the same time. If you have symptoms of both diseases, your doctor may call it asthma-COPD overlap syndrome.

People who smoke or breathe in pollution or chemicals at work for many years have higher chances of having COPD. That's why the condition often starts in middle age or later in life.

Asthma is sometimes caused by gene changes that are passed down through families. If one of your parents has the disease, you're more likely to have it. Symptoms often start in childhood.

Since asthma and COPD both make your airways swell, they both can cause shortness of breath,coughing, and wheezing.

One main difference is that asthma typically causes attacks of wheezing and tightness in your chest. COPD symptoms are usually more constant and can include a nasty cough.

To figure out which condition you have, your doctor will start with a physical exam and questions about your medical history. They’ll look at your nose and throat and listen to your lungs with a stethoscope. Your doctor will also want to do a test called Spirometry that checks how well your lungs work.

How does a genotype differ from a phenotype?

Answers

The sum of an organism's observable characteristics is their phenotype. A key difference between phenotype and genotype is that, whilst genotype is inherited from an organism's parents, the phenotype is not. Whilst a phenotype is influenced the genotype, genotype does not equal phenotype.

Answer:

What is the difference between a genotype and a phenotype? A genotype refers to the genetic characteristics of an organism. A phenotype refers to the physical characteristics. For example, having blue eyes (an autosomal recessive trait) is a phenotype; lacking the gene for brown eyes is a genotype.

Which is part of the nonspecific immune response?
O A. Fever
O B. B cells
O C. Lymphocytes
O D. Making antibodies

Answers

Answer:

A. Fever

Explanation:

Fever is part of the nonspecific immune response. Therefore option A is correct.

Fever serves as a defense mechanism against infections. When the body raises its temperature, it creates an environment that is less favorable for the growth and reproduction of many pathogens.

Higher temperatures can also enhance the activity of immune cells, such as white blood cells, allowing them to function more efficiently in fighting off the infection.

Fever is triggered by the release of certain chemicals, such as cytokines, by immune cells in response to the presence of pathogens.

These chemicals act on the hypothalamus in the brain, which regulates body temperature, causing it to increase.

Thus, fever is a physiological response of the body to infection or inflammation and is considered a part of the nonspecific immune response.

Question 1 of 10

Earlobes can be either attached or detached. The allele for attached earlobes
is recessive (e), and the allele for detached earlobes is dominant (E). What
must be true if a boy is born with attached earlobes?
A. He has a heterozygous genotype.
O B. He has no E alleles.
C. He has no recessive alleles.
O D. He has one of each allele,
SUBMIT

Answers

Answer:

B. He has no E alleles.

Explanation:

In order for the boy to have an attached earlobes phenotype, he must have no E alleles, because the E is dominant. So his genotype must be ee. If he has even just a single E allele (like Ee) he will have detached earlobes, because the dominant trait will mask the expression of the recessive trait.

Why not A or D: Heterozygous Ee (one of each allele) would result in detached earlobes.

Why not C: If he has no recessive alleles, EE, he would have detached earlobes.

If a boy is born with connected earlobes, he has no E alleles because the allele for detached earlobes is dominant (E), whereas the allele for attached earlobes is recessive (e). So, the correct option is B.

What is Dominant allele?

A dominant allele is one that will overpower a recessive allele's expression. Hence, only the trait linked to the dominant allele is manifested when a dominant allele and recessive allele coexist in the genotype of offspring. Consequently, for a recessive allele phenotype to manifest, both of the recessive allele must be present in the progeny.

A recessive allele causes connected earlobes (e) while the dominant earlobe detachment allele (E)

A child with the EE genotype would have disconnected earlobes.

As features of dominant alleles are manifested in heterozygous genotypes, offspring with the Ee genotype would also have disconnected earlobes. Only the child with the ee genotype would have connected earlobes. A homozygous recessive genotype is genotype ee.

Thus, the correct option is B.

DNA is translated into RNA and RNA is transcribed into proteins


RNA is transcribed into DNA and DNA is translated into proteins


DNA is transcribed into RNA and RNA is translated into proteins.

Answers

Answer:

DNA is transcribed into RNA and RNA is translated into proteins.

Explanation:

The central dogma of biology explains how gene is expressed in living organisms. Genes are segments of DNA that encodes or carry information for useful products called PROTEIN. However, these genes needs to be expressed. Gene expression occurs in two stages viz: transcription and translation.

Transcription is the first process of gene expression involving the synthesis of a RNA molecule from the gene-containing DNA molecule i.e. DNA is transcribed into RNA.

Translation is the second process of gene expression that involves the synthesis of an amino acid sequence from the information contained in the RNA transcript. These amino acid sequence forms the PROTEIN. Hence, RNA is translated into protein, which is responsible for certain phenotypes.
