Explanation:
midway Atoll is a critical habitat in the central Pacific Ocean which includes breeding habitat for 17 seabird species. A number of native species rely on the island, which is now home to 67–70% of the world's Laysan albatross population, and 34–39% of the global population of black-footed albatross.
Answer:
Mechanical digestion involves physically breaking down food substances into smaller particles to more efficiently undergo chemical digestion. The role of chemical digestion is to further degrade the molecular structure of the ingested compounds by digestive enzymes into a form that is absorbable into the bloodstream.
The "small animals diversify quickly" is true about life on Earth at this time.
<u>Option: D</u>
<u>Explanation:</u>
The appearance of the Cenozoic period took place with the vanishing of the dinosaurs, this scenario is nearly 65 million years earlier, which is continued till today. This era has been splited into two periods of time named as the Tertiary and the Quaternary. There were inevitably number of vacant spaces on Planet where animals could survive after the dinosaurs' absence.
Immediately after their extinction, several vacant areas have been studied in nature where animals could flourish. At the start of the Cenozoic the mammals which were small, mouse resembling animals getting scattered rapidly and also diversified quickly in nature, their size also started increasing. Massive elephants and rhinos, sabre-tooth cats and lions, horses and deers quickly got populated in Earth's plains and forests.
