<u>Answer:</u> A. Tissues
<em>Cells that perform similar functions combine to form tissues.
</em>
<u>Explanation:</u>
Cells are the smallest units in the body of an organism. Based on number of cells in an organism’s body they can be classified as unicellular or <em>multicellular organisms</em>.
It is the group of cells performing similar functions that form a tissue. Group of tissues performing similar function forms an organ. <em>Tissue structure and function may differ in plants and animals. </em>
Animal tissues are classified into four. They are epithelial tissue, connective tissue, nervous tissue and muscle tissue. In plants there are three tissue systems namely the <em>epidermis, vascular tissue and the ground tissue.
</em>
A line of indirect evidence of competition comes from the comparison between closely related species, whose population can be allopatric (geographically separated) or sympatric (geographically superimposed). In some cases, the allopatric populations of these species are morphologically similar and use similar resources. On the other hand, sympatric population, which are supposed to compete for resources, have body structures and use different resources. The displacement of characters is the tendency to have more divergent characteristics in sympatric populations of two species than in allopatric populations of the same two species.
An example of character displacement is the variation in size between populations of galapagos finches. Some of its populations are allopatric ( they live separately) and others are sympatric ( they live together). Peak size distributions they vary according to whether they are sympatric or allopatric. They look more alike when they are allopathic than when they are sympatric. That is, the peak size character moves when species enter competition.
Explanation:
Los síntomas del chancro incluyen una o más ulceras y dolor en los nódulos linfáticos, es decir en el área donde las piernas y el tronco del cuerpo se unen. La úlcera empieza como un granito doloroso que se llena de pus y luego se convierte en una llaga o úlcera.
