Which mutation causes either the inclusion of an extra chromosome in offspring or the deletion of an entire chromosome?

Answers

The answer to the question stated above is non-disjunction.

Non-disjunction causes either the inclusion of an extra chromosome in offspring or the deletion of an entire chromosome. Non disjunction during either meiosis I or meiosis II creates gametes that will generate trisomies if fertilized.

The answer is Nondisjunction

Explain why meiosis cannot happen without mitosis.

Answers

The mechanism is straightforward: in Metaphase one of Meiosis, chromosomes line up in two lines, with homologous across from each other, which allows them to interact by crossing over. In Metaphase of Mitosis, the chromosomes are all lined up single file, so the homologous chromosomes cannot interact.

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.

A student poses the question: How does the presence of dissolved salt affect the freezing point of water? To answer this question, the student set up two conditions. In the first condition, the student added salt to water in a container and referred to this condition as the variable. In the second condition, the student did not add any salt to water in a second container and referred to this condition as the control. The student took both containers and attempted to freeze the water at various temperatures to assess the freezing point. Would this be a valid experiment? A. Yes, because there is more than one variable. B. Yes, because there is one variable and a control C. No, because there is not more than one variable D. No because there is only one variable and a control
