The largest organ in an earthworm is its skin
Answer:
fire
landslide
avalanche
Explanation:
Fire, landslides, and avalanches are the examples of rapid environmental changes because they are able to destroy or affect the structure of living organism in a particular area. For example, fires can destroy all forms of life within days. A recent event of wildfire in Austria killed more than 1 billion of animals. Similarly, landslides and avalanche are geological calamities that are caused by the movement of a large mass of rock debris or snow moving downhill. The living organisms living there would be killed and this process can diminsh many forms of life (multicellular eukaryotes) rapidly.
On the other hand, (ecological) succession is a very slow process that results into change or disappearance of living organisms or particular species or ecological community in an area. This process can take place over decadaes, thousands or million of years. It can also lead to the species extinction as well.
Answer:
The correct answer to the question, 'which of the following scenarios is representative of how agricultural practice can affect the environment' is A. Option A is chosen because it is the only option that refer to another environment which is different from that of the farm. When fertilizers are washed to nearby ponds as a result of erosion, it causes a lot of negative changes in the pond. For instance, the chemicals in the fertilizer can be poisonous to some of the smaller organisms in the pond, this will result in the death of these organisms. Fertilizer run off can also cause excessive growth of plants such as algae in the pond. This may block out the light necessary for the survival of the organisms in the ponds and may also reduce the amount of oxygen available to the organisms living in the pond.
Explanation:
Answer:
b . chemical weathering
Explanation:
Chemical weathering is not affected the flow of groundwater through an aquifer but affect by the porosity and permeability. The rate of groundwater flow is controlled by two properties of the rock which are porosity and permeability. Porosity is the percentage of void space in a rock while on the other hand, Permeability is the quality of being permeable means able to be penetrated or passed through by a liquid or gas.
Behavioural genetics is the study of the effects of genes as well as well the environment on the behaviour of the individuals. The scientists who study the Behavioural genetics are known as behavioural geneticists.
In this case Dr. Hakim is studying the influence of genes and the environment on the aggression, which is a kind of behaviour. Hence, Dr. Hakim is a behavioural geneticists, and he works in in the field of behavioural genetics.
