The correct answer iare A. All organisms have had one common ancestor in the past, and C. Gorillas share an extinct ancestor with bonobos.
Explanation
The image shows an evolutionary tree that resulted in species such as the chimpanzee, orangutan, gorilla, bonobo, and humans. This tree shows nodes, which are the points shown on it. These nodes represent an extinct species as a common ancestor of the species of the next node that are connected to it. Therefore, the correct answers are A. All organisms have a common ancestor in the past, this statement is true because all the species shown in the tree are the result of different divisions of a first species that lived 13 million years ago. The second correct statement is C. Gorillas share an extinct ancestor with bonobos. Because in the graph it can be seen that 6 million years ago there was a node/species that is the common ancestor of the gorilla and the bonobo.
Answer: A). Flatworms
The illustration shows planaria which is a free living organism. It has flat shape and simple structure. This animal belongs to group of Flatworms. The flatworms do not have well developed respiratory and circulatory systems, these are simple organisms which derive the oxygen and nutrients by diffusion.
So that they can adapt to the situations that surround them in their environments.<span />
This is the day to day problem of a medical microbiology laboratory: the "tube containing a liquid nutrient medium" in the real world could, for example, represent blood culture bottles (aerobic or anaerobic). The basic process is as follows: a loop is first flamed to ensure sterility and then used to transfer a small portion of bacterial-laden liquid media to the agar medium by streaking it across the surface of a sterile petri dish. The dish is then covered, inverted, and placed in an appropriate incubator. When colonies begin to form on the surface of the agar plate, individual colonies can be taken up using the sterile loop for analysis or further propagation. The assumption is that a single colony represents growth from a single bacterium.
