Human Growth & Development Chapters 1‚ 2‚ & 3 Study Guide Chapter 1 1. What is meant by discontinuous and continuous development? Continuous development is a process of gradually augmenting the same types of skills that were there to begin with. Discontinuous development is a process in which new ways of understanding and responding to the world emerge at specific times. Broken down‚ Continuous means infants/preschoolers respond much like adults do and Discontinuous means they have their own

other groups such as fungi)‚ gametes are called sperm in males and egg cells or ova in females. Since meiosis has halved the number of sets of chromosomes‚ when two gametes fuse during fertilisation‚ the number of sets of chromosomes in the resulting zygote is restored to the original number. Meiotic division occurs in two stages‚ meiosis I and meiosis II‚ dividing the cells once at each stage. Before meiosis begins‚ during S phase of the cell cycle‚ the DNA of each chromosome is replicated‚ so that

The topic of abortion has long since been debated about whether or not it is morally just‚ but‚ now with the progression of science and technology‚ it can be inspected with more fact and less emotion. It has gone on for far too long that those who are pro-choice can let their emotions become apart of their argument. Unfortunately‚ the ability to choose abortion‚ when made legal due to the ruling from Roe v. Wade (History of Abortion‚ n.d.‚ p.1)‚ has been legal for so long it is extremely unlikely

of cells that results in two identical copies of one cell. This makes the ball of cells completely unique genetically. Yes‚ it is true that right after fertilization‚ all that has resulted is a ball of cells. However‚ the ball of cells‚ called the zygote‚ has the full potential to become a fully functioning human being. After all‚ you were just a ball of cells once‚ and look at you now. This is why abortion is morally wrong‚ because the ball of cells that is killed during an early abortion has the

a sexual or asexual process and its subsequent growth and differentiation into a new individual”‚ as stated by the Merriam- Webster English Dictionary. Sexual reproduction is a process whereby the female gamete fuses with the male gamete to form a zygote‚ which potentially develops into genetically different offspring. Essentially this means‚ we combine the genetic information from two individuals of different types or sexes in order to produce a new individual. Asexual reproduction‚ or agamogenesis

IVF‚ induces the ovulation of a woman‚ taking the eggs and joining them with the man’s sperm in a petri dish. After a couple of days the resulting of an embryo occurs‚ which leads to implantation into the woman’s uterus. Zygote intrafallopian tube transfer (ZIFT) and gamete intrafallopian tube (GIFT) are similar to IVF‚ except the sperm and eggs are placed straight into the fallopian tubes. Other technologies are also being used to reproduce children scientifically‚ for instance the freezing of eggs
