Reproductive & Nervous
Nervous & Endocrine
Circulatory & Respiratory
10
Cell receptors and Antibodies are similar in that
they are made by nerve cells
they function like a lock and key

18
When a pregnant woman smokes or drinks, the embryo is put at risk because the toxins can
enter the embryo when it eats
transfer to the embryo when the blood mixes with mother's
diffuse to the embryo via the placenta
enter the uterus through mother's navel
19

mitosis
recombination
22
Identify the organ labeled X
heart
testis
ovary
pancreas
23
The human immune system fights infection by releasing
antigens
antibiotics
ATP
antibodies
24
One job of the male reproductive system in mammals is to...
transport eggs for fertilization
protect the developing zygote
produce insulin for sexual reproduction
deliver gametes needed for reproduction
25
People with AIDS may become seriously ill from pneumonia because people with AIDS have
inherited risk of pneumonia
hormones that strengthen the infection
an allergy to pneumonia bacteria
difficulty fighting infections
26
