Explanation:
The brainstem is the posterior part of the brain that connects the cerebrum with the spinal cord. The brainstem can be divided into three parts: midbrain (i.e., mesencephalon), the pons (i.e., metencephalon), and the medulla oblongata (i.e., myelencephalon). The mesencephalon is a region of the brain composed of the tectum and tegmentum, which play fundamental roles in motor movement, auditory and visual processing. The corpora quadrigemina is found at the tectum region of the midbrain. The diencephalon is a small part of the brain located above the brainstem (between cerebral hemispheres); which contains the thalamus, hypothalamus, subthalamus, and epithalamus. In turn, the epithalamus is composed of the habenular nuclei, pineal gland, and the stria medullaris thalami. The cerebral aqueduct is a narrow channel (approx. 15 mm) in which the cerebrospinal fluid flows between the third ventricle and the fourth ventricle. The medulla oblongata is a long stem-like structure located in the brainstem of the brain, just in the place where the brainstem connects the brain to the spinal cord. The choroid plexus is a complex network of capillaries located at the cerebral ventricles of the brain, which serve to produce cerebrospinal fluid through ependymal cells that line the ventricles of the brain. The cerebellum is a major structure of the hindbrain and consists of the cerebellar cortex and a core of white matter having the cerebellar nuclei.
The function of each protein molecule depends on its shape, which in turn is determined by the protein specific sequence of AMINO ACIDS.
Proteins are a type of macro molecules that are made from amino acids, each protein is a long chain of different amino acids. There are twenty different amino acids in existence. Protein carry out several crucial functions in the cells of living organisms. The specific functions which a protein carries out is determined by its shape and the three dimensional structure of the protein. The shape of the protein depend on the type of amino acids that made up the protein. <span />
Photosynthesis breaks down glucose and release carbon dioxide
The answer is the second statement.
Quanitative refers to numbers. The only statement that contains a numerical information is "the tree was 20 years old when it was cut down".
The other statements only contain qualitative information.
