Answer:
Both plant and animal cells have a nucleus, where DNA replication takes place. Both plant and animal cells have cell walls, which provide support for the cell. Both plant and animal cells have a large central vacuole, which stores enzymes, nutrients, and waste for the cell.
Explanation:
Protease is used to digest proteins
The statement that best summarizes Darwin's theory of natural selection is D. Organisms best suited to their environment will survive and reproduce. This is becasue let's say some giraffes have short necks and some long necks and their food is leaves on high trees then the long necked giraffes will survive over short necked giraffes because short necked giraffes can't reach for their food and eventually there will be only long necked giraffes left and they will reproduce with other long necked giraffes and make long necked giraffes.
Answer:
We breathe because oxygen is needed to burn the fuel [sugars and fatty acids] in our cells to produce energy.) What happens in the process of respiration? (Oxygen is brought into the lungs via breathing, where it is transported by red blood cells to the entire body to be used to produce energy.
In human body, a joint is defined as a location where two or more bones meet and connect. The range of motion of joints refers to the measurement of the maximum distance and direction a particular joint can move. Most joints are connected in such a way that they allow movements in specific directions only.
The quantity of movement through a normal range for each joint is measured in degrees using an instrument called goniometer. Scientists had established standard range of motion values for most joints.
For ankle joint, downward movement of the joint, which is called plantar flexion ranges from zero to 50 degrees while the movement upward, which is called dorsiflexion ranges from zero to 20 degrees.
