. The members of theautosome pairs are truly homologous; that is, each member of a pair contains a full complement of the same gene.The sex chromosomes, on the other hand, do not constitute a homologous pair.
Claim: Earth's atmospheric CO2 levels were measured over the past 1000 years and correlated with average world temperatures. The data demostrate that Earth's temperature did not change during the period CO2 levels were steady. But the past 100 years show a dramatic rise in CO2 levels, with a corresponding rise in world temperatures. The CO2 rise can be traced back to the start of the industrial revolution, when machines began doing much of the work. These machine burn fossil fuels and the increased CO2 levels have led to a dramatic rise in world temperatures. The data clearly show the importance of reducing fossil fuel useage, as well as other CO2 emitters. A world of incresing temperatures will lead to greater natural disasters, such as storms, flooding, hurricanes, and drought - all of which upset the ecological balance of the planet.
Answer:
Explanation:
Gravity:
It is the force by which the elements of matter pulls together.
Explanation:
The gravity is depend upon the mass of matter. The more mass of object the more will be the gravitational force.
The earth is most heavier than all other matter that's why all matter pulls towards the earth.
For example;
when we walk on the earth, it pull us. Our mass is less as compared to the earth that's why we fall back on the earth instead of moving upward because our pull is negligible because of greater difference in masses. The earth mass is very high.
The gravitational force is inversely proportional to the square distance of interacting objects.
As the two objects are more distance apart from each other the less will be the gravitational force.
