Answer: More than 99 percent of all organisms that have ever lived on Earth are extinct. As new species evolve to fit ever changing ecological niches, older species fade away. But the rate of extinction is far from constant. At least a handful of times in the last 500 million years, 75 to more than 90 percent of all species on Earth have disappeared in a geological blink of an eye in catastrophes we call mass extinctions.
Though mass extinctions are deadly events, they open up the planet for new forms of life to emerge. The most studied mass extinction, which marked the boundary between the Cretaceous and Paleogene periods about 66 million years ago, killed off the nonavian dinosaurs and made room for mammals and birds to rapidly diversify
Explanation:
Meiosis is beneficial as it produces gametes that are genetically different to the parent cell, and when the gametes combine the offspring produced is made from combination of genes from both mother and father. The offspring is genetically unique, there is no other organism on the Earth with the exact same DNA sequences on their chromosomes.
Answer:
D. Fungi
Explanation:
Fungi does not contain the green pigment chlorophyll and therefore are incapable of photosynthesis.
Answer:
D) products, such as cans and glass bottles
Explanation:
Minerals are naturally occurring inorganic solid substances that have more or less chemical composition and characteristic physical properties. Minerals are used for many purposes. Minerals (such as aluminum and boron) are used by industries to produce products such as cans and glass bottles. Minerals are also used in the construction/ building of houses and other buildings. Limestone, shale and gypsum are used to produce cement. Minerals such as diamond, pearls, and ruby are also used to make jewelry such as rings but an industrial society would MOST LIKELY use minerals to make products such as cans.
