Cytoplasm is the thick fluid solution that fills each cell and is enclosed by the cell membrane. It is made up mostly of water, salts, and proteins.
The cells within your own body, and within plants contain cytoplasm. So two real life examples of cytoplasm would be the fluid in your own cells, and the fluid inside the cells of a tree.
Answer:
A.)are ectothermic organisms with variable body temperatures.
Explanation:
Invertebrates animal are animals that lack a backbone, Land invertebrates include insects,spiders, centipedes ,coelenterate, an arthropod, mollusc and the rest.
Ectotherms are also called called cold-blooded animal because their bl body temperature regulation is dependendent on external sources, such as sunlight or a heated rock surface. Some of the examples of ectotherms are fishes, amphibians, invertebratesand reptiles. The aquatic ectotherms body temperature is usually compare closely to the temperature of the surrounding water
Ectothermic species that lives in temperate regions usually experience rapid and potentially stressful changes in body temperature simply because of weather changes even among amphibians there is variation in their temperature
It is believed that naturally occurring periods of temperature variation negatively impact amphibian health.
Mutalism, commensalism, and parasitism
The correct option are as follows:
cholera is a bacterial infection of the small intestine.
vaccination provides protection against cholera.
the cholera vaccine is made up of a weakened form of the bacteria that causes cholera.
the vaccine will stimulate production and elicit an immune response.
- If the infection occurs again, the body will produce an even greater attack on the bacteria because of acquired immunity.
- By injecting a heat-killed, weakened organism or its component (antigen) into the body, vaccination aids in the development of immunity. Memory cells and antibodies are produced as a result.
- Memory cells aid in the development of immunological memory, which helps the immune system to respond to microorganisms that the body has previously encountered with greater strength and efficiency during a secondary immune response.
- Memory B cells and memory T cells aid in the development of immunological memory.
