Chapter 1.1, Problem 1TY

In vitro fertilization (IVF) is a common assistive reproductive technology for couples who are struggling to conceive naturally; however, the success rate of IVF is, at best, about 55%. Researchers seeking to improve the success of IVF need to observe the interaction between sperm and eggs in order to better understand the factors that favour fertilization. Obviously, larger sperm and eggs would be easier to observe, even with the aid of microscopy. On this basis, which of the following vertebrate groups might be a good model for studying IVF because they are likely contain species with large sperm and eggs? Group of answer choices a) fish b) amphibians c) reptiles d) birds e) mammals

What is the positive ways that inherited factors are indispensable in determining the appearance of an individual

Suppose you are a carrier of fragile X syndrome and want to have children. Would you choose pregnancy, adoption, or surrogacy? If you became pregnant, would you opt for prenatal diagnosis? Explain your decisions.

Develop an original chart AND/OR diagram that will illustrate how prenatal development is influenced by environmental AND/OR genetic factors.

The lifespan perspective on development assumes that     development is static, stable, and entirely predictable.     events that occur during infancy and early childhood have the strongest impact on the life course.      development is affected by a blend of biological, psychological, and social forces.      after adulthood, little development occurs.

How to interpret what the positive & negative result means

State five characteristics of human development from a life – span perspective and their implications to child care, education and parenting. “Growth is an evidence of life“or“Development is an evidence of life”.What does it mean? What does it imply to a person’s development? If your approach to human development is traditional are the characteristics of human development from a life-span perspective acceptable? Explain your answer

Four factors are considered when determining a person’s biological sex: 1) chromosomes, 2) hormones, 3) primary sex characteristics that are features essential for sexual reproduction (internal reproductive structures and external genitalia), and 4) secondary sex characteristics, features that typically appear during puberty and are different between the sexes, but are not directly involved in reproduction (for example, females typically have enlarged breasts and widened hips; and males typically have increased facial and body hair, increased muscle mass, and a larger Adam’s apple). Given that the top male athletes outcompete the top female athletes by about 10% in most sports, provide a justification for how each of these four factors is or is not likely to contribute to performance differences between sexes.
