Answer:
The process of creating a metamorphic rock is a chemical change because we are changing one rock into a whole new different type of rock.
Explanation:
Remember a chemical change is changing the core basis of what something is. Common example of a chemical change is burning wood, when you burn wood that wood turns into ash, which means it's no longer wood.
In this case metamorphic rocks are usually formed by intense heat and pressure, which converts the rock into a different type of rock.
To conclude, metamorphic rocks are formed by intense heat and pressure, which converts a rock into a different rock. "The process of creating a metamorphic rock is a chemical change because we are changing one rock into a whole new different type of rock."
Hope this helps.
Explanation:
Xenopus laevis is allotetraploid: it has 2 sets of homologous chromosomes originally from one species and 2 sets of homologous chromosomes originally from another species, making a total of 4 sets of chromosomes. During meiosis, every chromosome has another homologous one with which it can pair, producing viable gametes that have the complete genetic information of the species.
Mules, however, are allodiploid: they have one set of chromosomes from a donkey and another set from a horse, making a total of 2 sets of chromosmes. But those two sets are not homologous, so during meiosis the chromosomes can't pair and the gametes will have errors that make them inviable, making mules sterile
About 20 minutes<span>Sperm can live outside of the body for only about 20 minutes
to an hour, depending on how exposed the semen is to the air and other
environmental factors. To avoid the slightest risk of pregnancy, a woman
should make sure that ejaculated semen doesn't get at all close to her
vagina.</span>
