Answer:
Higher oxygen levels means animals can grow larger and still maintain the supply of oxygen to their muscles. Falkowski and colleagues calculated fluctuations in the atmosphere's oxygen levels from cores of deep-sea rocks dating back 205 million years.
1. contracts 2. increase 3. move apart 4. density 5. cool down 6. decrease 7. move closer sorry if there not correct
Answer:
The correct answer will be option-D
Explanation:
The evolution of vascular tissues in plants from non-vascular plants was an adaptive feature to survive in the terrestrial environment. The group of plants in which vascular tissues evolved and developed is the Pteridophytes which contained stellar organization of the vascular bundles.
The pteridophytes exhibited xylem and phloem which allows the rapid uptake of the water and nutrients from the soil which allowed the growth of the plant and since plants got enough water and nutrients from the soil, they adapted to grow tall so that they can maximize the output of photosynthesis in bright sunshine.
Thus, option-D is the correct answer.
The broadest group in the modern classification system of living organisms is the domain.
<h3>What are systems of classification?</h3>
Classification systems are forms of group and collecting information so that they may be reached with other data.
The type of category system used will depend on what the data are planned to measure. Some datasets may use multiple classification systems.
Thus, the domain is the broadest group in the modern classification system.
