For mitosis, two cells are created, and for meiosis, four cells are produced. So the answer is B. Because in mitosis, the chromosome replicates once and divides once. In meiosis, the chromosome replicates once and divides twice. That's why the cell has half of the chromosomes after meiosis.
The properties of the original elements are completely changed.
For example, in the compound called "iron(II) sulphide", it is composed of iron and sulphur, that are chemically combined together. The element iron is attracted to magnets. Meanwhile, iron(II) sulphide is not attracted to magnets.
Another example is where sulphur has a yellow colour, but iron(II) sulphide has a brownish colour. As we can see, even the physical properties (colours) are completely different.
Therefore, the properties of the original elements are completely changed when they're combined into compounds.
In C4 plants, photosynthesis is compartmentalized into two; light-dependent stage and light independent stage. The light-dependent stage occurs in the mesophyll cells of the leaf. Here, CO2 is fixed into oxaloacetate by PEP carboxylase enzyme. The oxaloacetate is then converted to malate that is then transported to bundle-sheath cells (around the leaf veins). The CO2 is then released from the malate and the gas molecule is subsequently fixed by RuBiSCO like in C3 plants. The biggest advantage of C4 photosytheis is that the wasteful process of photorespiration is greatly reduced.
Plankton they are the base for marine life
Why temperature affects heart rate in ectothermic organisms? If the temperature is within the optimal range for enzyme activity more ATP will be produced and the heart will beat faster due to increased metabolic activity and energy availability.
