Are you asking whether this is true or false?
I don't really like it as a definition, so I would go with "false".
The thing it, its not really the study of differences (although it might include studying some differences) as much as it's a study of the interactions of the organisms and their environment: it does not have to include any differences at all!
Human beings and natural resources are closely interrelate to each other. On the one hand, human resouyrce is quite essentialfothe socio-economic development of a nation and on the other,rapid population growth is theratening the existamce of human life by creatin imbalance between population and natural resources.The view of social scientists is that population with groth rate of one percent needs a growth of natural resources of four percent to maintain the optimum living stander.The mode of utilization of resources should maintain sustainability in the society. Natural resources are very essential to sustain the life of human being.But rapid population growth has inreased the demand of the resources. It has caused the over expioitation of resources.Thus,natural resources are being degraded.Landslid e,soilerosiosn,pollution,flood,climate change,etc.are the mjore problems for the environment degradation.

Man is the consumer and preserver fo the resources.Human being should not misuse the resources.people should consume these resources rationally.Rapid population growth over-exploits the natural resources.So,population growth should be checked.Similarly,human avtivities should be in accordance with carrying capacity of the earth.Long-term vision and effective planning are essential while carrying development works.The relationship between human beings and components of natural resources.
The genetic information found in an offsrping is found in the DNA.
<h2>
answer:</h2>
a heterogeneous mixture
<h2>
explanation:</h2>
A heterogeneous mixture is commonly any mixture that is not uniform in combination - it's a non-uniform mixture of smaller fundamental particles. Using different means, the particles in the mixture can be separated from one another. In a heterogeneous mixture, the elements do not mix completely, and the individual items that form the mixture can be identified. Heterogeneous mixtures can typically be separated back into their original components by chemical or physical means.
D) The Earth was hit by a one or more objects from space 65 million years ago. The iridium layer shows an extraterrestrial cause for the extinction at the Cretaceous Tertiary boundary, discovered by the Alvarez family. The first discovery of this layer was in the Bavarian alps, in Lattengebirge. The Alverez family proposed that the extinction of the dinosaurs was due to a large meteor hitting the Earth at the end of the Cretaceous period, marking the KT boundary with this clay layer which has a high content of iridium. Iridium is not common on Earth, but is common in meteors.
