Answer the following question given this paragraph: The nucleus of many cells also contains a central region called the nucleolus . The job of the nucleolus is to build ribosomes. These ribosomes flow out the nuclear pores into the cytoplasm. Ribosomes are organelles that make proteins in the cytoplasm. See the composition of the nucleus pictured below ( Figure below ). Q: The job of the nucleolus is to build what? Choices: - chromosomes - electrons - cells - ribosomes A:
ribosomes
Q: Answer the following question given this paragraph: 28.3 Fetal Development The fetal period lasts from the ninth week of development until birth. During this period, male and female gonads differentiate. The fetal circulatory system becomes much more specialized and efficient than its embryonic counterpart. It includes three shuntsthe ductus venosus, the foramen ovale, and the ductus arteriosusthat enable it to bypass the semifunctional liver and pulmonary circuit until after childbirth. The brain continues to grow and its structures differentiate. Facial features develop, the body elongates, and the skeleton ossifies. In the womb, the developing fetus moves, blinks, practices sucking, and circulates amniotic fluid. The fetus grows from an embryo measuring approximately 3.3 cm (1.3 in) and weighing 7 g (0.25 oz) to an infant measuring approximately 51 cm (20 in) and weighing an average of approximately 3.4 kg (7.5 lbs). Embryonic organ structures that were primitive and nonfunctional develop to the point that the newborn can survive in the outside world. Q: In humans, what period lasts from the ninth week of development until birth? Choices: - third trimester - plasma period - development period - fetal period A:
A: fetal period

Air is taken in through the spiracles , openings on the sides of the abdomen. Q: On insects, what are the openings on the sides of the abdomen that allows respiration to occur? Choices: - gills - wings - chloroplasts - spiracles A:
**Answer**
spiracles
