Polar bears have large paws so that their body weight spread our over more space on the ice.
Imagine then as snowshoes for a human. They keep you up =).
Hope that helps! =)
Hello there!
Your answer would be lung cancer, chronic bronchitis, emphysema and asthma.
Years of smoking and exposure to air pollutants can contribute to the incidence of lung cancer, chronic bronchitis, emphysema and asthma.
Lung cancer is one of the factors that is caused by smoking and air pollutants. This happens when too much lung cells are being produced in the lungs at once, which causes cancer cells to grow, this would form a tumor in the lung. There are many treatments that could be taken to remove this tumor. This is one of the things that are caused by smoking and air pollutants.
Chronic Bronchitis is another factor that is caused by smoking and air pollutants. This also involves the lungs. Chronic Bronchitis is a disease in the lungs that caused inflammation in them, which is very dangerous to the human body. Growth of mucus, coughing, and etc are symptoms of this. This is another factor that is caused by smoking and air pollutants.
Emphysema is another factor that is caused by smoking and air pollutants. This is a disease that causes the alveoli (a balloon shaped pass way in the raspatory system) to over swell. This mostly causes a shortness of breath to a person. This is another factor that is caused by smoking and air pollutants.
Asthma is another factor that is caused by smoking and air pollutants. This condition is very common to people who have smoked, been around smoke, or has been around places whose air is very polluted. This conditions causes the airways to clog up, which makes it hard to breathe. This is another factor that is caused by smoking and air pollutants.
200J
Explanation:
Given parameters:
Force on boulder = 100N
Distance moved = 2m
Unknown:
Work done = ?
Solution:
Work done on a body is the force applied to move such body in the direction of the force.
Work done = force x distance
Input the parameters in the equation:
Work done = 100 x 2 = 200Nm or 200J
The work done in lifting the boulder is 200J

Answer:
Complementary RNA (cRNA) is a copy of a strand of RNA that will bind to the appropriate region of the original molecule. If the original RNA stand had a base sequence of AUU, for example, the sequence of the cRNA strand would be UAA.
Hope it helps.
have a wonderful day!
