Answer:
A radioactive (unstable) phosphorus isotope is made to replace a nonradioactive isotope of phosphorus in the molecule
Explanation:
Phosphorus has both unstable (radioactive) and stable isotopes. In any compound that contains phosphorus, the phosphorus atom present may be either a stable isotope of phosphorus or an unstable isotope of phosphorus.
However, if the molecule contains a stable nonradioactive isotope of phosphorus, it is possible to convert this isotope in the molecule to the unstable radioactive isotope by carefully carrying out exchange reactions in which the phosphorus isotope replaces the nonradioactive isotope in the molecule.
This is usually done in order to create radioactive tracers which are used to study chemical reactions and biochemical processes.
I believe the blank is "mass."
Answer:
Its gas-filled swim bladder explode.
Explanation:
The gas-filled swim bladder of deep sea fish is explodes when brought to the surface too rapidly because in the deep sea there is high pressure on the gases that is present in its tissue so when the fish is brought to the surface too rapidly, the high pressure is removed and the gases that were compressed in the tissue of the fish in deep sea are releases to expand that causes explode of gas-filled swim bladder. There is very high pressure in the atmosphere when we go deep into the sea which put pressure on the lungs of humans and gas-filled swim bladder of fishes which decrease its volume.
When a person's thyroid malfunctions, they can feel tired,<span> nervous, or their muscles can feel weak. They can experience weight gain or loss; impaired memory; or, if female, it can affect their menstrual cycle.

Answer:
Because Intercalary meristems are found in the the stem part of the sugarcane in whole length.
Explanation:
- As we have studied about meristem regions, that these are the regions found at the nodal areas which are able of cell division and growth. Intercalary meristem are present in the nodes of sugarcane stem which lead to the rapid increase in elongation of stem.
- Intercalary meristem are located at the base of leaves and nodes that leads to the increase in length.
-
On the tip of sugarcane, apical or tip region meristem are found. When the tip region is removed, the presence of intercalary meristems play the role by facilitating the elongation of stems in sugarcane.
