Some aquatic animals possess stinging cells. These cells are called: Hypothocysts. Nematocysts. Psoriacysts. None of the above.

The correct answer is - Nematocycst.

Explanation:

Nematocysts are aquatic animals that contain stinging cells known as cnidocytes. These organisms are members of the phylum Cnidaria. These carry a organelle called cnida or cnidocyst.

An example of such an organism is Jellyfish. Sting cells are specialized neural cells that release extensive Golgi secretion venom that causes a stinging experience to the prey the nematocyst.

succession returns a disturbed

ecosystem to a more stable state. this is also classified into two (2) types:

primary succession and secondary succession. the primary succession arises when

a new land is transformed and a bare rock has been exposed providing an environment

that can be occupied for the first time. while, secondary succession occurs

when a previously occupied environment was disturbed that kills much of all its

community

explanation:

measuring light intensity

light meters can be used to measure light intensity. the meter is held at the soil surface and pointed in the direction of the maximum light intensity, and then the meter is read.

errors can be made when measuring light intensity by accidentally shading the light meter. the reliability of the results can be checked by taking many samples.
