Explanation:
The primary motor cortex has projections for the entire human body map, or homunculus. Axons from the primary motor cortex project from the frontal lobe to the spinal cord.
Answer:cell wall
Explanation: bacteria are prokaryotes,they do not have membrane bound molecules.they are surrounded by rigid cell wall that gives them their shape.bacteria do not posses nuclear membrane.prokaryotes are either archaea or bacteria.
Bacteria have cell walls which are made up of peptidoglycan.peptidoglycan consists of polysaccharides interconnected with muramic acids.the sugar polymer is cross-linked by amino acids.this peptidoglycan gives the bacteria cell structure and shape.pennincillin Is an antibiotics that works by affecting the structure of the peptidoglycan,there by allowing water into the bacteria cell. This causes the bacteria to burst and die,there by reducing it's population
Answer:
Explanation:
Yes. Animals and humans have instincts. Every creature does. Most of the time offspring are born in populations that are thriving so their young and their genes can be passed on.
The nephron forms the basic functional unit of the kidney and comprises of various parts as shown in the picture.
Urine is formed by the process of ultrafiltration, and collected in the proximal tubule, from where it passes to the loop of Henle, the distal tubule and the collecting ducts, undergoing the processes of reabsorption and secretion to form the urine that is ultimately passed out. The concentration of urine so formed is governed by the water and elecrolyte balance of the body, and the required concentration is achieved by the processes mentioned above in the nephron
