Answer:
Mutation
Explanation:
Mutation creates new genetic variation in a gene pool. It is how all new alleles first arise.
The sense that is most closely related to Balance would have to be touch because you have to be touching the ground to actually have balance

Answer:
<em>The best inferential explanation is that the heavy metal concentration was gotten from the build up of small amounts of heavy metal in the birds, gotten from consuming fishes from a heavy-metal -polluted water body.</em>
<em></em>
Explanation:
If a sample of fish-eating bird species is found to contain such a large concentration of heavy metal, then the primary source of the heavy metal concentration in their body will be from their food source. Fish-eating birds are in most cases, solely dependent on fish for their food. Most of them do not eat any other food apart from fish, so the problem can be pin-pointed to the fishes they consume. <em>The best inferential explanation is that the heavy metal concentration was gotten from the build up of small amounts of heavy metal in the birds, that is gotten from ingesting fishes that have ingested heavy metals in them. This can be as a result of the pollution of water bodies like streams, lakes and seas from heavy-metal-containing industrial wastes. </em>

C
Explanation:
The illustration shows carbon dioxide moving from the atmosphere to the plant. This can only occur through the process of photosynthesis because the process utilizes carbon dioxide and sunlight energy to make glucose (hence storing the carbon in the plant). Plants are major carbon sinks and play a significant role in mitigating global warming by reducing the accumulation of carbon dioxide as a greenhouse gas in the atmosphere

C
Explanation:
Overfishing reduces marine populations because the activity reduces a species' population too drastically to very low levels such as the individuals left are not adequate enough to repopulate the species leading to a spiraling effect of reduced population size and growth leading towards extinction. It is important that Ben ensure that fishing for the shrimp does not reduce the population below this critical point where re-population of the shrimp may become impossible.

A
Explanation:
Logging will enure the current generation benefits from the current natural resources, in this case, the tree. Planting of at least a tree for every downed tree ensures that the young tree will grow and mature and will be utilized by upcoming generations. This ensures a sustainable cycle with each generation benefiting from the natural resources (trees). The other choices are not as sustainable.

Explanation:
When an oceanic plate is pushed under a continental plate, it sinks into the hot mantle.
Water is forced out of the subducted plate and seeps into the mantle above.
The water lowers the melting point of the hot mantle, which then liquefies to form magma.
