DNA or deoxyribonucleic acid is macromolecule composed of nucleotides (nitrogen nucleobase, deoxyribose sugar and phosphate group) which carries genetic information (instructions). Instructions within DNA are for development, growth, reproduction and many other functional roles of an organism.
All of the cells within an organism contain the same genome (full set of DNA-chromosomes). When cells begin the process of differentiation (cells become specified) their genome stays the same, but the gene expression is different (different genes are on or off).
Answer:
The correct answer is: we would lack the energy we need to function.
Explanation:
Glucose is a type of sugar that gives us energy. When we eat something that contains glucose, our body releases insulin, a hormone from our pancreas, which absorbs the excess glucose in the blood and stabilizes sugar levels. When insulin is released, it travels through the bloodstream to the body's cell. After that, the cells convert glucose into energy to use right then or store it for later use.
In other words, if our bodies could not metabolize glucose we would be hungry and exhausted because we would not get enough of the other nutrients (like proteins and fibers) to sustain our energy.
Answer:
Erythrocytes, or red blood cells, are by far the predominant cell type in the blood smear. They appear as biconcave discs of uniform shape and size (7.2 microns) that lack organelles and granules. Red blood cells have a characteristic pink appearance due to their high content of haemoglobin.
Answer:
a process by which molecules of a solvent tend to pass through a semipermeable membrane from a less concentrated solution into a more concentrated one, thus equalizing the concentrations on each side of the membrane.
