Explanation:
The question is incomplete as the diameters of the Willapa Bay urchins were not given.
However, I'll give a general way to solve this problem.
Average is calculated using:
i.e. Sum of all diameters divided by the number of bay urchins.
The diameter of urchins is usually between 6cm to 12cm; So, I will assume the following diameters for 10 urchins.
10cm, 8cm, 10cm, 7cm, 9cm, 10cm, 6cm, 10cm,8cm, 8cm
Using the above data, the average is:
If you want to know how it looks outside of your body then that's when your fingers are wrinkled like if you soak your hands in water or take a long shower or bath that could be when water is entering your cells.
Hope this helps!
The complete statement made by Stephen Hawking is: "though much of its behaviour through out history, has been pretty stupid, and not calculated to aid the survival of the species."
If one looks at our history, there are some events that defy our capacity for logical thinking. One would think that, as we possess this capacity, we would be able to direct our decisions towards the survival of the human species.
However, in many cases greed and the desire for personal gain have taken precedence. One good example was the burning of the great library of Alexandria, one of the most significant libraries in the ancient world. This magnificent collection was lost during the siege of Alexandria, when Julius Caesar set on fire the ships in the harbor.
Another example is the atomic bomb, when science has been used to invent one of the most destructive weapons known to us. Atomic warfare is still a threat that may end all life on Earth.
Furthermore, the greed of some corporations has led to multiple ecological catastrophes that endanger not only other species but our own future as well. One example is the Bhopal gas leak in India, where in 1984, due to poor maintenance, the chemical plant released 30 metric tons of methyl isocyanite into the atmosphere.
Answer:
C. habituation trials continue after the response has disappeared.
Explanation:
habituation involves the complete elimination of a particular response (i.e, zero frequency of occurrence). If the stimulus cintinues to be presented for an additional number of trials, then, although no further changes occur, the response will exhibit lower levels of recovery (e.g, spontaneous recovery is reduced) as if the response would have fallen below a zero frequency.
Answer:
The cell membrane contains pores to allow nutrients to enter and waste to leave the cell. cell membrane is SELECTIVELY PERMEABLE which means that the cell membrane controls what enters and leaves the cell. cell membrane protects all cells.
