Baby: The First Nine Months

   1) When does the baby: (a) begin to move (b) open it eyes (c) begin to kick its mother so that she    notices?
   (a)The baby begins to move at 10 weeks (b) the baby begins to open its eyes at 26 weeks (c) the mother begins to feel the baby's kicks at 18 weeks

   3) Babies which are born early are kept warm in incubators. Why?
       Babies premature need to be kept warm because there mechanism to maintain body temperature is still not functioning and they can't maintain proper body temperature, so they need an incubator

       Girls need to be given the injection before they reach puberty because if given during puberty it is not effective.

6.4 Growing Up: Non-Human Animals

   2) How does: (a) frog embryo get the oxygen it needs? (b) a human embryo get the oxygen it needs?
       (a) Frog embryos get their oxygen through the egg (b) A human embryo gets its oxygen through the blood pumped into its body through the umbilical cord
   3) (a) What is the yolk's job in the egg? (b) As the chicken grows, the egg's yolk gets smaller. Why?
       (a) The job of the yolk is to provide food for the growing embryo (b) The yolk gets smaller for two reasons; to make space for the chick, and because the chick has been feeding on it

Dissection of a Flower

Today we dissected a flower to see if we could find and photograph the different parts of the reproductive system, as this would help us visualize and understand how this system worked.

Here we see the female reproductive part, the pistil, and the different parts of it

Here we can see the inside of the ovary, although it it isn't very clear here, this is where the eggs should be

Here we see the male part of the flower, the stamen, where the pollen is produced

here we see the petal, which is a superficial part of the flower that is supposed to attract insects
