According to the activation-synthesis theory of dreaming, the source of a dream is neuronal firing in the lower brain stem. It is also known as the medulla oblongata or just medulla. It is essential in processes like blood pressure and heart rate. Also, it is responsible in a number of reflexes in the body or the involuntary actions like coughing, sneezing and vomiting. It is said to contain cells that would turn REM on and off. From recent research, it is the part of the brain that is the origin of the electrical impulses where dreams are results. It is connected to other parts of the brain which controls memory, movement, hearing and vision.
The question is incomplete as it does not have the option which are:
- primates A and B are more closely related to each other than either is to primate C.
- all three primates appeared on Earth at about the same time.
- either primate A or primate B must be a direct ancestor of primate C.
- primate C must have been the ancestor of both primate A and primate B.
Answer:
Primates A and B are more closely related to each other than either is to primate C.
Explanation:
In the given question, on the basis of the given information, it can be predicted that the Primate A and B are more closely related to C as the DNA sequences of these two primates are almost similar. The similarity of the sequence suggests that these primates have descended or diverged from a common ancestor.
The DNA sequence of C is different from both A and B which shows that both A and B are different from the C.
Thus, the selected option is the correct answer.
The rock found in the riverbed that is smooth is from the result of weathering of water in the river and erosion. The rock deep underground was most likely a product of erosion. The dirt and ground above it were eroded and displaced there to cover the rock.
Answer:
The word are semipermeable membrane; partially-permeable membrane; differentially-permeable membrane.
It allows the passage of only certain types of molecules through diffusion and occasionally by facilitated diffusion.
