The brain's suprachiasmatic nucleus regulates the body's circadian rhythms. The suprachiasmatic nucleus is a minute region of the brain located in the hypothalamus above the optic chiasm, the circadian rhythm is the 24-hour cycle of organisms, related to sunlight and temperature.
The monosaccharides that are produced when sucrose is digested would be glucose and fructose.
Any theory must contain a meaningful concept with new evolution to accept by the scientific community
Stem cells arise from the inner mass of the cell
Signalling factors trigger differentiation in stem cells
Genes that lead to the production of undifferentiated blood cells are activated
Signalling factors cause undifferentiated blood cells to produce red blood cells
Explanation:
Red blood cells are formed in the bone marrow. The precursor to the RBC is stem cell which is undifferentiated and pluripotent. The stem cell gets differentiated to form immature RBCs. Immature RBC then gets divided and becomes mature. Stem cell giving rise to RBC is called Haemoctytoblast. The process of erythropoiesis takes 2 days to form new red blood cells
Answer:
Lysosomes
Explanation:
Lysosomes are membrane bound organelles that contain degradative enzymes. They degrade worn-out cellular parts and may also be used by cells to degrade/destroy invading bacteria or viruses. Hence, since white blood cells are primarily responsible for fighting infections, it is expected that they have a high amount of lysosomes (which they indeed do have in high amount).
