A technician uses an ultrasound to examine a fetus. She observes that the fetus is covered in a fine, downy hair, and that a uterus has formed. She
tells the mother that she is carrying a 15 week old fetus. Why is the
technician wrong?*

A. fine, downy hair does not appear until the 26th week of pregnancy

B. a uterus forms in the fetus in the 9th week of pregnancy

C. both of these features form between weeks 19 and 20 of a pregnancy

D. both of these features form between weeks 15 and 16 of a pregnancy

i dont think this is the place to ask this.

maybe uh, try talking with someone you know or like about this.

life can be tough.

the aorta is the large artery leaving the heart branches into smaller arteries, which eventually branch into capillaries.the arteries carry oxygen and nutrients away from your heart, to your body's tissues. the capillaries are small, thin blood vessels that connect the arteries and the veins. the statement that arteries carry oxygen-rich blood to capillaries is true. veins on the other hand are blood vessels that take oxygen-poor blood back to the heart.
