This is a volume of space that is empty of matter. Example: Sound cannot travel here.
aleksandr82 [10.1K]

Answer:

Vacuum

Explanation:

A vacuum is usually defined as a space in which there is an absence of matter. It can also be said that there is an extremely low amount of pressure due to which the particles present in it are not affected by any type of process that occurs in space. The value of pressure is lower than the value of normal atmospheric pressure.

For example, sound cannot travel in space because there is no medium such as water and air through which the sound waves can propagate.

A wildlife biologist is investigating a sudden increase in the death rate
Ann [662]

Answer:

circulatory and respiratory

Explanation:

The body system of Birds possesses a higher arrangement of organs to perform a particular function. The organs form a system which includes the organs and associated structures.

When the biologist observed the shortage of the dissolved oxygen and increase in the level of dissolved carbon dioxide, this could be the result of the failure of the circulatory system which supplies these gases on the body and the associated respiratory system which helps in the exchange of these gases with the atmosphere.

Thus, circulatory and respiratory is the correct answer.
