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.

Answer:
a, b, c are correct
Explanation:
Enhancers are DNA sequences that increase the rate of transcription. Enhancers act as binding sites for transcription factors that stimulate the transcription of one or more genes and enhancers stimulate transcription for specific cell type or tissue in a specific manner. The possible reasons for the lack of enhancers in bacteria include.
Enhancers often provide a mechanism for cell-specific transcription of genes, and most bacteria lack differentiated cell types.
Bacterial operons make coordinate regulation of protein synthesis by enhancers unnecessary.
There is little to no intergenic space on bacterial chromosomes, which makes long-range-acting enhancer sequences unnecessary.
Therefore, the correct options are (a), (b), and (c).
"The experimental hypothesis may be that if Asian worms are introduced into a <u>deciduous forest</u>, the soil's nutritional composition will alter. The control group would consist of a region of the forest that has been worm-free in some way. But in order to serve as a control, this forest would experience the same amount of sunshine, heat, and precipitation. In order to determine if Asian worms actually have an impact on the forest ecology, the scientists could then analyze the amounts of nitrogen, phosphorus, and sulfur in the two portions of the forest."
Deciduous forest- A deciduous forest is one that is mostly made up of trees that shed their leaves in the fall.

It depends on the situations. In the first situation, a Yy gene crosses with a Yy gene. 3 out of 4 of the outcomes have a capital Y in them, meaning that they have a dominant yellow allele. The bottom-right box has two lower-case y's, so it will be green. In the second situation, a YY gene crosses with a Yy gene. Here, all 4 out of 4 of the outcomes have at least one capital Y, so they will all be yellow. Hope that helps!
