Which sequence of events best explains the interaction between the components of the Arctic ecosystem feedback loop
nikitadnepr [17]

The sequential events in the Arctic ecosystem feedback loop are: Global temperature increases → permafrost thickness decreases → methane increases → global temperature increases. It is harmful to the Earth.

The Arctic ecosystem is a feedback loop because the warmer the temperatures, the less sea ice (permafrost) is observed.

The Arctic ecosystem feedback loop is a dangerous phenomenon because it accelerates global warming.

Permafrost refers to ice ground that remains completely frozen (0°C) for at least two (2) or more years straight.

Why might a phylogeny based only on molecular data show a different pattern of relationships than a phylogeny of the same taxa b
Kitty [74]

A phylogeny of the same taxa based only on morphological traits:

Some highly conserved genetic sequences can result in unrelated species appearing closely related in a molecular phylogeny, and not reflect the same pattern as the morphologic phylogeny.

Gene sequence changes may not result in morphological changes.

Gene sequences always provide more data than morphological traits.

Morphological analyses always provide more data because each morphological trait is the result of the expression of many genes.

The molecular data may be based on the analysis of introns, which aren't expressed and don't contribute to the evolutionary history of a group of taxa.

Why is molecular data more accurate?

Phylogenetic trees reconstructed from molecular sequences are often considered more reliable than those reconstructed from morphological characters, in part because convergent evolution, which confounds phylogenetic reconstruction, is believed to be rarer for molecular sequences than for morphologies

olga55 [171]

Answer:

d. RNA polymerase II.

Explanation:

The main enzyme responsible for RNA synthesis is RNA polymerase, which <em>catalyzes the polymerization of 5'-triphosphate ribonucleosides (NTP) </em>directed by a DNA mold.

Eukaryotic cells contain <u>three types of nuclear RNA polymerases</u> that transcribe different types of genes. Protein-encoding genes are transcribed by RNA polymerase II to give mRNA.

Contrast the three categories of materials and their relationship to transmitted light, making sure to include at least two exam
Ann [662]

Answer:

Transparent, translucent, and opaque.

Explanation:

Transparent, translucent, and opaque are the three categories of materials that has a relation with transmitted light. Transparent objects are those from which the light passes through e.g plastic, water etc while on the other hand, translucent objects are those from which some of the light pass through e.g sunglasses and wax paper etc and opaque objects are those from which no light can pass through their body e.g wood and metal etc.
