The correct answer is fire extinguisher.
Before someone starts to fuel a boat there should be fire extinguisher.
When a person is fueling the fuel might overfill and spill the fuel into engine or to passenger compartment and this can increase the risk of fire explosion and if spilling fuel to the water will harm the marine environment that is why a person should have fire extinguisher when fueling.
Some precautions which are taken when refueling are,
1. Refueling should be done on daylight when artificial light is not needed.
2. When refueling a person should not smoke.
3. Portable tank should be refueled in the tank and not in the boat.
Answer and Explanation:
A jaw might provide you much information about its function and about the animal´s adaptations to different scenarios. These structures are very useful in characterizing a group as a new species. Of course, there are many other factors to consider as well.
When you are working with the mandibles of different known species and the mandible of a new species, and you need to get information about the species behavior, such as its diet, you need to compare all the pieces involved in the feeding act. This is,
- Teeth. Teeth are the most evolved pieces in animals, and thus, provide important information about species. They are very important in taxonomic identification and phylogeny. Animals might be homodont or heterodont, which means that all teeth are equal, or there are different kinds of teeth with different functions. According to the diet, teeth vary in shape, and thus you can find herbivore teeth, carnivore teeth, omnivore teeth. The number of teeth might also vary according to the feeding strategy and the diet of the animal.
- Processes. The shape of the mandible is another very important component. The sizes of processes might provide information about muscular development, and through this knowledge, you can assume the importance of the mandible while feeding, and the strategies used to feed according to their diet. Animals might develop different muscles that are more or less useful while feeding on different prey. Processes are the insertion point of these muscles, so according to their size, you might estimate the muscle mass, and thus, the muscle use.
- Length. The mandibular length of many species is correlated with their prey and feeding strategy. By meassuring the ramus you might also infer the diet.
So, in any case, if you have many jaws belonging to different known species and you also know what is the principal diet of these species, then all you need to do is to compare the teeth, processes, and sizes of your new species with the ones of the known species. By comparing all these structures you will have strong evidence of your species diet.
The cell is the specialized smallest unit which forms tissues and eventually organ system and a full organism explains the statement.
Explanation:
Cell is the basic structural and functional unit of life. All life originates from the cells and group of cells.
Cell has a full equipped machinery which is capable of growth and performing independent function. The specialized cell arising from the zygote by totipotency will direct the formation of tissues which will club to form specialized organs followed by a full organism.
The specialised cell as nephrons in kidney, gametes in sex organs, neuron in brain, cardiac cells in heart, fundic cells in stomach, udder cells in mammary gland, rods and cone cells in eyes etc.
Baby born with full-grown specialized organs will have growth by the process of mitosis in the cells which will ensure growth and repair of the cells and eventually the organs and the organisms. Cells of various organs communicate via cell signalling and are in unison in performance.
It can be concluded that two single cells give rise to full organism in which all the organs are working in unision as a system.
