vodomira [7]

Answer:

b. Some carbon dioxide will move from chamber A to chamber B.

Explanation:

The two chambers are separated from each other by a separator that exhibits the properties of the cell membrane. It means that the separator film is semi-permeable in nature. The concentration of CO2 in the chamber A is 80%. This is relatively higher than its concentration in chamber B (20%). The concentration gradient will drive the passive diffusion of some of the CO2 from chamber A to chamber B so that the concentration becomes equal in both the chambers.

Why do scientists often take more than one representative sample
adell [148]

A representative sample is a reflection of the characteristics of the certain group ( population) as a whole. Sample size is the number of representative samples (individual pieces of data) used to calculate a set of statistics. The greater this number the better the determination of the average values of their data. Having greater number of samples also avoids errors from testing a small number of possibly atypical samples.

Describe the functions of bone. In what ways does bone<br> participate in homeostasis?
densk [106]

Answer:

Functions of the bones in the human body:

Support, protection, movement, mineral homeostasis

Explanation:

- Support: the bones provide a rigid support frame for muscles and soft tissues.

- Protection: the bones form several cavities that protect the internal organs from possible trauma. For example, the skull protects the brain against blows, and the rib cage, formed by ribs and sternum protects the lungs and heart.

- Movement: thanks to the muscles that are inserted into the bones through the tendons and their synchronized contraction, movement occurs.

- Mineral homeostasis: the bone tissue stores a series of minerals, especially calcium and phosphorus, necessary for muscle contraction and many other functions. When necessary, the bone releases these minerals in the blood that distributes them to other parts of the body.
