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.
It is a good advantage because they will immediately know how to survive and take care of themselves. Innate behaviors are behaviors that animals exhibit that they did not learn. For example, baby monkeys and apes (including humans) will grasp things with their feet and/or hands. Nobody has to teach them to do this, they are just born knowing how to do it. It is most definitely an advantage.
Answer:
1. Respiration results in the production of energy and Breathing doesn’t provide energy.
2. Breathing is a biophysical process that involves the exchange of gases through inhalation and exhalation while respiration is a biochemical process to release energy from organic compounds which are then used for performing different physical activities.
Because regular leaves don't conserve water well, the cactus developed these modified leaves to adapt to its extremely dry environment. The spines are better at conserving water and surviving in hot temperatures. Regular leaves provide a large surface area for evaporation of water to occur, the tiny spines do not.
