The natural extinction rate defines background extinction
<u>Explanation:</u>
Extinction endured primarily control of paleontology. Background extinctions are the continuous importance of common environmental variations, local disasters, or inter species conflict. Background extinction is principally a local appearance. It happens only one or a few species at any time, habitually inside a distinct area.
Ecologists measure that the present-day extinction rate is 1,000 to 10,000 times the background extinction rate between one and five species per year because of deforestation, environment loss, over hunting, pollution, climate modification, and other human activities.
The correct answer is that they help to retain moisture in terrestrial habitats.
Arthropods exoskeletons and mollusk shells both help to retain moisture in the terrestrial habitats.
Arthropod is an invertebrate animal which have an exoskeleton, paired jointed appendages and segmented body. They are characterized by their jointed limbs which are cuticle and are made of chitin.
They are the most species-rich members of all ecological guilds in most environments.
Molluscs are termed as large phylum which is of invertebrate animals. They are the largest marine phylum and they live in terrestrial habitat and freshwater.

Option D blue whale is the correct answer
<span>The answer should be B. The results of a previous experiment are presented as an introduction to a new experiment.
Material that used for </span>presentation of background research should have a credible information. A<span>mazing new drug is described in a television commercial mostly false and it is not backed up by scientific study. Rumor from </span><span>second-hand accounts definitely not credible. A newspaper is not a scientific study and could give false information.</span>
Answer:
a peach is round the Earth is round
to model the Earth layers you can slice the peach and make layers out of it similar to Earth layers
earth has 4 layers so you'll need to slice 4 parts of the peach
