What is the origin of etiology of asthma

Answers

Asthma is a chronic disease of the lung that has been increasing at an alarming rate in industrialized countries around the world over the last few decades. Although considerable progress has been made in our understanding of the underlying pathogenesis of the disease, the exact causes of the increasing prevalence are unknown. Studies suggest that most asthma develops in early childhood and that environmental factors present early in life may be crucial in the development of disease. One potential explanation for the recent epidemic referred to as the "hygiene hypothesis" postulates that factors that have resulted in a reduction in exposure to microbial products and/or infections in the western world may be contributing to this rise in disease prevalence. As early life influences are known to play an important role in establishment of asthma, studies have focused on the interface between mother and child that occurs during gestation and through breastfeeding. In this regard, the body of evidence regarding the relationship between breastfeeding and asthma indicates benefit but with the potential for risk. While providing population-level protection from infections and atopy in infancy and early childhood, breastfeeding might also pose an increased risk of atopic asthma among children with asthmatic mothers.

In a year, a population of lions had four births, two deaths from disease, one natural death, five emigrations, and five immigrations. In the same year, a population of zebras had five births, three deaths, four emigrations, and one immigration. Which best explains the data?

Answers

The statement, which best explain the data is this: THE ZEBRAS HAVE A LOWER POPULATION GROWTH RATE THAN THE LIONS.

From the data given in the question, the population growth rate for lions and zebra can be calculated. The formula for calculating population growth rate is: Population growth rate = [Number of birth - Number of death] + [Number of immigration + Number of emigration]

For lions, we have: Population growth rate = [4 - 3] + [5 - 5] = 1 + 0 = + 1

For zebras, we have: Population growth = [5 - 3] + [1 - 4] = 2 + [-3] = 2 - 3 = - 1.

From the calculation above we can see that, the lions have a higher population growth rate than the zebras.

Answer:

Zebras have a lower population

Which individuals in the pedigree are identified and labeled carriers for red-green color blindness?

Answers

Do you have the pedigree to share? Red green color blindness is an x linked trait, which means that it is found on the X chromosome. X linked traits are often recessive, and this is why they usually show up in males, such as the case of red green colorblindness. A male has only one copy of the X chromosome, so if a recessive x linked trait is present, he does not have the option of the dominant version of the trait to show up. A recessive X linked trait can present itself in a female, but since she has two X chromosomes, she would need to have two copies of the recessive trait for it to present itself. This is why color blindness is less common, but still possible in females. I hope this helps you with your pedigree.

Explain the relationship between adaptation natural selection and evolution
