A safety symbol is a sign or symbol on an object to show whether it can affect our bodies negatively. this is also a warning sign to people in the laboratories
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.
Answer:
Physarum first grows as single-celled amoebae, but the amoebae fuse, and the organism loses its 'cellular' makeup. As the organism continues to grow, nuclei divide without cell division. The resulting bag of nuclei is called a 'coenocyte' or 'plasmodium'.

Answer:
Dehydration is a concern since dehydration can lead to severe complications, such as seizures, swelling of the brain, kidney failure, shock, coma and even death. Signs and symptoms of dehydration include: Headache. Dizziness or lightheadedness.
Explanation:
Answer:
Cleavage and Fracture
Explanation:
Cleavage is the way a mineral breaks. Many minerals break along flat planes, or cleavages—some in only one direction (like mica), others in two directions (like feldspar), and some in three directions (like calcite) or more (like fluorite). Some minerals, like quartz, have no cleavage. Cleavage is a profound property that results from a mineral's molecular structure, and cleavage is present even when the mineral doesn't form good crystals. Cleavage can also be described as perfect, good or poor.
