When scientists discuss the Sixth Extinction, they are referring to which pattern in the rate of extinction?
Travka [436]

Explanation:

The Holocene extinction, otherwise referred to as the sixth mass extinction or Anthropocene extinction, is an ongoing extinction event of species during the present Holocene epoch (with the more recent time sometimes called Anthropocene) as a result of human activity.[3][4][5] The included extinctions span numerous families of plants[6] and animals, including mammals, birds, reptiles, amphibians, fishes and invertebrates. With widespread degradation of highly biodiverse habitats such as coral reefs and rainforests, as well as other areas, the vast majority of these extinctions are thought to be undocumented, as the species are undiscovered at the time of their extinction, or no one has yet discovered their extinction. The current rate of extinction of species is estimated at 100 to 1,000 times higher than natural background extinction rates.

Organization is one of the characteristics of life. Explain how your observations under the magnifying glass support this idea.
seraphim [82]

Answer:

All living things are made up of cells. Cells are building blocks of life. Cells are the simplest level of organization. The structure of multicellular organisms are made up of many parts that are required for survival of organisms. The level of organization in multicellular organisms includes: cells, tissues, organs and organ system. The organization is necessary for the body of the organisms to function properly as a characteristic feature of living being.

Magnifying glass is a convex lens that is fitted in a microscope can be used to magnify the image of object under observation. A magnifying glass in a microscope can be used to magnify minute cells and small living creatures. All cells aggregate to form tissues. It can be used to see the arrangement of cells in a tissue specimen and small organelles like chloroplast, mitochondria, nucleus and others.

Therefore, observations under the magnifying glass support  the idea of organization is one of the characteristics of life.
