Answer:
Definetly global warming, the biggest problem we have on our planet
Explanation:
Answer: D) More runoff water is created, and less is returned to the atmosphere.
Explanation:
The deforestation is a phenomena of clear cut and removal of forests from the land so as to obtain the forest land for construction of houses, or for using wood for furniture industry. The forests are the main contributors to the water cycle. The transpirated water from the forests accumulates in the atmosphere which when condense results in rain. Also, the rain water will be again absorbed by these forests.
The deforested land will be prone to flood and surface runoff in the absence of trees. This water is of deteriorating quality does not contribute the water cycle as compared to forested land.
Answer: A sugar-phosphate backbone (alternating grey-dark grey) joins together nucleotides in a DNA sequence. The sugar-phosphate backbone forms the structural framework of nucleic acids, including DNA and RNA. This backbone is composed of alternating sugar and phosphate groups, and defines directionality of the molecule.
Explanation:
The release of toxins such as heavy metals into the water bodies has been deeply frowned at .This is because toxins usually have a negative effect on aquatic species. The negative effects include:
- Developmental dysfunction
- Gender imbalances
Toxins also gives rise to developmental dysfunction in the animals . The toxins ensures that there is a shortage by interfering/reacting with the nutrient needed for the growth of these organisms.
The issue of gender imbalance is also true as some toxins causes water bodies to be warmer which favors the presence of female aquatic species such as reef fish.
Toxins causes aquatic bodies to be short of oxygen supply as the elements or compounds released vie for oxygen with the animals which may lead to less reproduction rates and death in severe occasions.
