Answer:
True
Explanation:
Neurotransmission is modulated by the dopamine transporter. Dopamine transporter leads to activation of protein kinase which in turn reduces the uptake of dopamine. Due to this, the Vmax reduces and the affinity of transporter remains unchanged.
However, in the presence of cocaine activity of dopamine transporter is inhibited as cocaine and dopamine-binding sites are more or less similar to each other. Dopamine stops blocks the dopamine transporter and reduces the uptake of dopamine. This leads to constant Vmax but reduced affinity of transporter
Hence, the given statement is true
Vitamin B12 is mostly found in animal-based food.
Vitamin C is found in abundant in plant-based food.
Explanation:
Vitamin B12 also called cyanocobalamin is obtained only from animal-based foods like fish, meat, egg and dairy fruits. Vitamin B-12 is helpful in the maintenance of nerve cells and blood cells. It is required to prevent certain types of anaemia, also an integral part of DNA formation.
Vitamin B12 is a fat-soluble vitamin. Vitamin B1 is found in animals because animals like cows store the vitamin from their gut bacteria and eventually passed to the ones consuming them.
Vitamin C is a water-soluble vitamin found in mainly citrus fruits. These are required for the formation of skin, tendons, collagen and cartilage. It is also helpful in maintenance of bones and teeth. It helps in the repair of skin.
Vitamin C is produced in plant cells by biochemical pathways because it needs them as coenzyme and oxidants for their growth.

Answer:
Compact and spongy bone
Explanation: Compact and spongy bone develops directly from sheets of mesenchymal (undifferentiated) connective tissue. The flat bones of the face, most of the cranial bones, and the clavicles (collarbones) are formed via intramembranous ossification.
