Answer the following question given this paragraph: Within seconds of birth, the umbilical cord is cut. Without this connection to the placenta, the baby can't exchange gases, so carbon dioxide quickly builds up in the baby's blood. This stimulates the baby's brain to trigger breathing, and the newborn takes her first breath. Q: What structure connects the fetus to the placenta, allowing the exchange of gases? A:
OPTIONS:
- sediment cord
- skin cord
- belly button
- umbilical cord
umbilical cord

OPTIONS:
- movement
- freshness
- consciousness
- homeostasis

Answer: homeostasis

Question: Answer the following question given this paragraph: Q: All three axes are established before the zygote begins to undergo what? A:
OPTIONS:
- cloning
- birth
- twinning
- cleavage
Answer: cleavage

input with options: Answer the following question given this paragraph: The placenta is a spongy structure. It consists of membranes and blood vessels from both mother and embryo (see Figure below ). The placenta passes oxygen, nutrients, and other useful substances from the mother to the fetus. It also passes carbon dioxide and other wastes from the fetus to the mother. The placenta lets blood from the fetus and mother exchange substances without actually mixing. Thus, it protects the fetus from being attacked by the mother's immune system as a "foreign parasite. ". Q: Designed to exchange materials, what spongy structure consists of membranes and blood vessels from both mother and embryo? A:
OPTIONS:
- endometrium
- uterus
- umbilicus
- placenta
output: placenta

Q: Answer the following question given this paragraph: In sexually reproducing organisms, parents pass a copy of each type of chromosome to their offspring by producing gametes. When gametes are fertilized and form offspring, each has a unique combination of chromosomes and genes from both parents. The inherited gene combination determines the characteristics of the offspring. Q: In sexually reproducing organisms, parents pass a copy of each type of what to their offspring by producing gametes? A:

OPTIONS:
- molecule
- genome
- phenotype
- chromosome

A: chromosome

Answer the following question given this paragraph: At some time in the past, a variation probably came from a mutation. A mutation is a random change in an organism's genes ( Figure below ). Mutations are natural. Some are harmful, but many are neutral. If a mutation is harmful, the organism may not live to reproduce. If the mutation is beneficial, that organism may have a better chance to survive. An organism that survives is likely to have offspring. If it does, it may pass the mutation on to its offspring. The offspring may be more likely to survive. Q: What is a random change in an organism's genes? A:
OPTIONS:
- meiosis
- infection
- accumulation
- mutation
