Answer:
The expansion of water upon freezing is vital to life on Earth. It is what causes ice to be less dense as a solid than as a liquid. This means that ice floats in liquid water. ... Water freezes when its molecules are no longer moving around enough to break their hydrogen bonds.
Explanation:
the factors are light intensity, carbon dioxide concentration and temperature. So you know which one is.
Answer:
a) b + i = d + e
b) b + i < d + e
c) b + i > d + e
Explanation:
Data provided in the question:
b = birth
d = deaths
i = immigration
e = emigration
Now,
a) a population in equilibrium
this means increase in population is equal to decrease in population
i.e
b + i = d + e
b) b) a declining population
this means increase in population is less than decrease in population
i.e
b + i < d + e
c) an increasing population
this means increase in population is increase in decrease in population
i.e
b + i > d + e
<u>Answer:</u>
In ecology, catastrophes permanently alter the physical structure of the existing environment.
<u>Explanation:</u>
- The ecological disturbances include flood, strom, plague, fires, earthquakes, tsunami, volcanic eruptions, climatic change and impact of humans on the environment like deforestation ,nuclear testing etc.
- These factors can have a visible impact on the structure of the earth and permanently alter the environment.
- The visible effects of these disturbances are global warming, extinction of selective species, change in the course of rivers, submergence of coastal areas, sudden movement of the tectonic plates and formation of sudden cracks on the earth's crust.
The graph shows the ages of the women who have breast cancer, which range from ages 40 to 50. So it shows that this type of disease is most commonly diagnosed in women of these ages. Apparently, women are more prone to getting breast cancer the older they are. This is because as you get older, you lose some of your strength to fight these carcinomas so the risk of mutation grows higher as well.
Hope this helps!
