Answer:
flexion - depression
extension - elevation
adduction - medial rotation
abduction - lateral rotation
Explanation:
Flexion is the process of bending an arm or leg. It occurs as a result of the contraction of the muscles. Depression is a downward movement. Hence, flexion refers to the depression of an arm or leg.
Extension is the process of stretching the body parts. Elevation is an upward movement. Hence, extension refers to the elevation of body parts.
Adduction is the movement of a limb or other part of the body towards the midline or another part of the body. The movement of the limb towards the midline of the body is known as medial rotation.
Abduction is the movement of a limb or other part of the body away from the midline of the body. The movement of the limb away from the midline of the body is known as lateral rotation.
Answer:
pH is really a measure of the relative amount of free hydrogen and hydroxyl ions in the water. Water that has more free hydrogen ions is acidic, whereas water that has more free hydroxyl ions is basic. Since pH can be affected by chemicals in the water, pH is an important indicator of water that is changing chemically.
Answer:
Gap junction is a connecting channel in animal cell while plasmodesmata is connecting channel in plant cell.
Explanation:
Both Gap junction and plasmodesmata are form of connecting channel found in cell but Gap junction is found in animal cells while plasmodesmata is found in plant cell.
The structure of gap junction comprises of hemicahnnes (connexons). These hemichannels are made up of endoplasmic reticulum of cells that are later relocated by the Golgi apparatus to the cell membrane thereby forming transmembrane proteins named connexins. While Plasmodesmata are cylindrical in shape and lined with plasma membrane. There are narrow tubes known as desmotubules which are made up of smooth endoplasmic reticulum
There are three types of gap junction while there are several forms of plasmodesmata
The earliest homidid that belonged to the same genus as modern humans was probably homo habilis.
Habilis means <em>able, </em>so he was able to do certain things that modern humans can as well.
