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.
Answer:
E, A, B, D, C
Explanation:
Leukocytes are cells that are found in the blood stream and they help identify foreign materials and fight against them, they are also called white blood cells.
The process that is given in the question looks like this when the steps are put in the right order;
E, cytokines are secreted where needed and they signal certain cells according to the action that needs to be taken.
A, endothelial cells which are located on the surface of the blood vessels produce selectins.
B, selectins which are proteins that are made up of single chain and help with the cell adhesion with other molecules, carbohydrates in the example.
D, leukocytes roll along the walls of the blood vessel.
C, and lastly leukocytes crawl out of the vessel into the adjacent tissue.
I hope this answer helps.
A single genetic locus that controls more than one trait is said to be pleiotropic
When an organism reproduces they pass on their genetic information in the DNA to their<span> offspring.
