Your brain and spinal cord are surrounded by a clear, colorless fluid called cerebrospinal fluid (CSF). The cerebral spinal fluid's primary role is washing the brain of metabolic waste. So, the answer is c.
The fluid that circulates between two of the meninges, the thin tissue layers that cover and protect the brain and spinal cord, as well as inside and around the empty regions of the brain and spinal cord.
The choroid plexus, a type of brain tissue, produces cerebrospinal fluid in the ventricles, or hollow regions, of the brain. also known as CSF.
CSF also serves the following functions: protecting the brain by acting as a cushion surrounding it to prevent damage, controlling the pressure inside the skull, nutrient delivery to the brain, getting rid of waste in the brain.
Therefore, the primary role of cerebral spinal fluid is to wash the brain of metabolic waste. Thus, option (c) is correct.

why are protons (h ) pumped across the inner mitochondrial membrane? answer they are the waste products of cellular respiration. their movement back across the membrane generates atp. they are pumped across the membrane so that they can get to the other side. i am unsure it is the step that makes the citric acid cycle work as a cycle. i don't know yet
Protons are pumped across the inner mitochondrial membrane because a retention gradient develops between the inter mitochondrial space.
In cellular respiration, the proton pump uses energy to transport protons from the mitochondrial matrix to the inter-membrane space. It is an active pump that generates a concentration gradient of protons across The mitochondrial membrane is inward because there are more protons outside the matrix than inside. During electron transport, energy is used to pump hydrogen ions through the mitochondrial inner membrane, from the matrix to the space intermembrane. A chemiosmotic gradient causes hydrogen ions to flow back through the mitochondrial membrane into the matrix, via ATP synthase, producing ATP.

what is the complementary dna sequence for the dna strand shown in the figure below?
The complementary DNA sequence for the DNA strand shown in the figure below is 5-''TAACGTCATGG-3''.
Nucleotide: DNA nucleotides are deoxyribose sugars with phosphate groups and one of four nitrogen bases.
Adenine (A), Thymine (T), Cytosine (C), Guanine (G)
Complementary Sequence: Because DNA consists of two strands, each DNA sequence also possesses a counterpart sequence that runs in parallel. In the complementary sequence, the nucleotides Adenine (A) and Thymine (T) are always coupled together, while Cytosine (C) is often paired with Guanine (G).
As the given strand is 3''ATTGCAGTACC3'" the complementary strand will be 5-''TAACGTCATGG-3''.
The missing figure is attached.
