Which benefits do mangrove trees provide to surrounding coastal wetlands? Check all that apply.

Anon25 [30]

The mangroves trees help in holding the soil in place, they help in absorbing the energy of waves, and they help in filtering water and better the quality of it.

Mangroves are a kind of estuarine or coastal wetland, featured by the existence of salt amended shrubs and trees, which develops beside the coast in subtropical or tropical latitudes all around the world. Several of the mangroves forests can be determined by their dense tangle of prop roots, which make the trees seem to be standing on stilts above the water.

The mangroves safeguard the shorelines from destructing hurricane, storms, winds, and floods. They help in inhibiting erosion by stabilizing the sediments with their tangled root infrastructure. They sustain the clarity and quality of water, trapping the sediments and filtering pollutants arising from land.

Part a - identifying the processes of replication, gene expression, and recombination this activity requires that you correctly

Naddika [18.5K]

I found the exercise on the internet with the images and brief descriptions. Attached is an image of it.

To the DNA replication bin:
-Image of one cell dividing into two cells, and the mother cell has its DNA being unfolded and replicated.
-"DNA -> 2DNA (copying one DNA molecule to make two identical DNA molecules)"

To the gene expression bin:
-Image of only one cell with some arrows within it indicating the gene expression flow: DNA -> mRNA -> protein
-"DNA->mRNA->protein"
-"transcription"
-"translation"

To the recombination bin:
-Image with two cells being one the donor and the other one the recipient. The recipient has DNA with different colours pretending to represent that its DNA has different origins.
-"transformation"
-"conjugation"
-"transduction"
