Evolutionary theory focuses on the long term adaptation of the species over more generations. Every species has 2 long-standing biologically based drives: survival and reproduction. Other answers are not biologically based drives for every species.
Answer:
A ) survival and reproduction.
Answer:
As this ratio of land and man was given by demographer Thomas Malthus who said population on grew in an arithmetic and earth production in a geometric fashion.
Explanation:
- The population or the production capacity of the earth will double and increase as long as it's kept stable i.e no interference from the outside world or human world. Even when there are lower birth and population is still decreasing the earth still will produce less as comparatively due to the slow growth of resources.
- This population may increase due to the number of medical aid facilities provided or may increase due to the population reaches its maturity and gets fixed or stabilized.
- Population and growth in resource distribution are always linked to the demographic changes in the population distribution around the world. \
- As the country of Africa has large scale childbirth and is next after Asia in terms of the population even after several years when its population stabilizes there still going to be pressure on the natural resources as these are finite in numbers.
Answer:
Ecosystem, community, species, population
Explanation:
The correct answer is option C, that is, physical weathering.
The weathering resulting due to the influences of changing temperatures on a rock, making the rock to split apart is known as physical weathering. There are two main kinds of physical weathering, that is, exfoliation and freeze-thaw.
Physical weathering takes place mainly in the locations, where few plants grow and little formation of soil occurs, like hot deserts and mountain regions. It takes place either via repeated freezing and melting of water or via contraction and expansion of the rocks surface layer, which is baked by the sun.
