Fades into outer space
No clear upper boundary
Not all scientists agree that it is part of atmosphere
The phrases above are describing <u>B) exosphere layer of our atmosphere</u>
Explanation:
- The exosphere is the uppermost region of Earth's atmosphere as it gradually fades into the vacuum of space.
- Air in the exosphere is extremely thin - in many ways it is almost the same as the airless void of outer space.
- The exosphere is perfect for placing satellites as there is very little friction and they are able to orbit fairly easily without being disrupted. Most of the molecules that exist in the exosphere end up being pulled back into earth's lower atmospheric levels by gravity.
- The air in the exosphere is very thin, and is made up mostly of helium, and hydrogen.
- Traces of other gases such as atomic oxygen and carbon dioxide can also be found. The upper level of the exosphere is the farthest point from earth that is still affected by earth's gravity.
- The exosphere is an important atmospheric layer as it functions as a transition zone between the earth's atmosphere and outer space
- It is the layer in which we can find artificial satellites that carry out constant studies of the earth and outer space. It also acts as a transit zone towards outer space.
Meiosis.
Meisois is is the reproduction of the sex cells (sperm and egg), while mitosis is between a regular cell. Another difference is that Meiosis splits into 4 cells, while mitosis splits into 2.
Hope this helps!
Answer:
Tetanospasmin toxin; Pulmonary embolism
Explanation:
Clostridium tetani produce a toxin called tetanospasmin. Tetanospasmin is the strong neurotoxin that blocks the motor neurons that control the muscles. Which results in stiffness of muscles.
Tetanus toxin ca cause blockage of lung artery (pulmonary embolism) and thus can cause death by:
- Stopping your breathing
- Pneumonia
- Cardiac arrest
Its electrons relese and it dies. or another way to say it is that it burns.
