During digestion, where is digested food absorbed into the blood stream?
pancreas |
|
stomach |
|
small intestine |
|
large intestine |
The small intestine is where most digestion takes place. As food travels along the small intestine it gets broken down completely by enzymes secreted from the walls. These enzymes are produced in the small intestine as well as in the pancreas and liver. After the enzymes break down the food, the resulting substances are then absorbed into the blood via capillaries in the small intestine walls.
A dominant trait will be expressed when paired with:
a recessive trait |
|
a dominant trait |
|
a gene |
|
a chromosome |
The traits represented by genes are inherited independently of each other (one from the male and one from the female gamete) and a trait can be dominant or recessive. A dominant trait will be expressed when paired with a recessive trait while two copies of a recessive trait (one from each parent) must be present for the recessive trait to be expressed.
Tough fibrous cords of connective tissue that connect muscles to the skeleton are called:
tendons |
|
ligaments |
|
vertebra |
|
cartilage |
Tough fibrous cords of connective tissue called tendons connect muscles to the skeleton while another type of connective tissue called ligaments connect bones to other bones at joints (elbow, knee, fingers, spinal column).

|
all of these |
|
expressed |
|

The traits represented by genes are inherited independently of each other (one from the male and one from the female gamete) and a trait can be dominant or recessive.
