The spinal cord is the structure that carries messages between the brain and other parts of the body.
Answer: A - Rods are more numerous than cones
Explanation: Rods are found everywhere in the retina except the fovea (a tiny pocket in the retina where just about all of the cones are located).
B. The macula lutea is another word for fovea, no rods are found there.
C. Rods are utilized in low-light conditions and are not <em>sensitive</em> to wavelengths of light.
D. Cones are responsible for perceiving color and not rods.
E. The main function of the rods is to help us see in low-light conditions (scotopic vision), so this answer would be incorrect.
Answer:It is easier to remove electrons and produce CO2 from compounds with three or more carbon atoms than from a two-carbon compound such as acetyl CoA.
Explanation:Like the conversion of pyruvate to acetyl CoA, the citric acid cycle takes place in the matrix of the mitochondria. Almost all of the enzymes of the citric acid cycle are soluble, with the single exception of the enzyme succinate dehydrogenase, which is embedded in the inner membrane of the mitochondrion. Unlike glycolysis, the citric acid cycle is a closed loop: the last part of the pathway regenerates the compound used in the first step. The eight steps of the cycle are a series of redox, dehydration, hydration, and decarboxylation reactions that produce two carbon dioxide molecules, one GTP/ATP, and reduced forms of NADH and FADH2. This is considered an aerobic pathway because the NADH and FADH2 produced must transfer their electrons to the next pathway in the system, which will use oxygen.
Answer: a) codon b) anticodon
Explanation:
The process of protein formation in a cell is called Translation.
Translation process begin when tRNA enters ribosome. tRNA consist of three nucleotides called anticodon that matches with the codon present in the mRNA. Anticodon in tRNA binds with a specific codon present in mRNA and so results in the addition of amino acids to produce protein chain.
Hence, tRNA matches with the codon on the mRNA, it brings in the corresponsing anticodon to begin forming the protein.
