Why is primary production and animal life concentrated at the surface in pelagic regions of the open-ocean?

Photosynthesising primary producers require sunlight. Therefore, in the ocean, phytoplankton would be concentrated within the surface layers of the ocean where the sunlight penetrates. Phytoplankton support a wide range of marine life: zooplankton feed on phytoplankton, which in turn support fish and so on.

Answer:

Collagen genes.

Explanation:

Phylogenetics helps to study the evolutionary relationship among the different group of organisms. The different characteristics like DNA sequences, mitochondria sequences can be used for the construction of phylogeny tree.

Collagen genes can be used to study the evolutionary relationship as mammals contains nearly 30% of total protein. The collagen gene shows the most of the conserved sequences among the different group of organisms and shows the most recent evolved characters in vertebrates.

Thus, the correct answer is collagen genes.

The stomata you view on the surface of the leaves are used in gas exchange and the guard cells regulate this exchange. What do y
beks73 [17]

Answer:

They will collapse and shut off the stomatal pore

Explanation:

The guard cells are regulated by the presence of water. When water is present, they become turgid and open up the stomatal pore and when water is inadequate, they become flaccid, collapse and close up the stomatal pore as a result.

<em>If the leaf is left under the microscope for too long, there will be loss of water by evapotranspiration and the guard cell will become flaccid and collapse as a result and the stomatal pore will become closed.</em>
