Both statements about the experiment are observations.
Answer:
The correct answer is option (B) "In pursuing a swerving insect, a beetle alters its course while running and its pauses become more frequent as the chase progresses".
Explanation:
One hypothesis suggest that the tiger beetles stop for a moment when they attack because it can't keep its pace and they have to rest, while the other hypothesis suggest that the tiger beetles could not process the rapidly changing visual information when running. The experiments results would support only the second hypothesis if they show that in pursuing a swerving insect, a beetle alters its course while running and its pauses become more frequent as the chase progresses. If a beetle altering its course have to stop more often than a beetle running straight, it would make sense that it has to stop because is unable to process the changing visual information rapidly enough.
About 97.5% of the earth's water is saltwater and about 2.5% is fresh.
Most living things do not leave fossils behind because we decompose before we are covered by sediments. Fossils are formed when plant or an animal dies and is buried in mud. So this does not tend to happen as often.
PART 1
1. They nurse their young with milk produced by mammary glands.
2. <span>There are international laws and treaties that protect marine mammals.
3. </span><span>Unfortunately, many marine mammals are considered endangered species and there are still threats to most of their populations, such as illegal hunting, pollution, climate change, and habitat loss.
4. T</span><span>hey have adapted to living all or part of their life in the ocean.
5. </span><span>To keep warm in the ocean, most of them depend on a thick layer of blubber (or fat).
6. </span><span>To be able to stay under water for long periods, they store extra oxygen in their muscles and blood.
7. </span><span>They also have more blood than land mammals in proportion to their body sizes, can direct their blood flow to only their vital organs (such as their heart and lungs), and can slow their heartbeat down so they are using less oxygen in a dive.
