T cells. When HIV arrives in the lymph nodes – around 24 to 48 hours after exposure – they activate other immune cells, such as CD4 t-cells, HIV's primary target.
<h2><u>Answer:</u></h2>
The recreation center is adjoining the Colorado River, 4 miles (6 km) north of Moab, Utah. In excess of 2,000 common sandstone curves are situated in the recreation center, including the notable Delicate Arch, just as an assortment of one of a kind land assets and developments.
A characteristic curve, regular scaffold, or (less usually) shake curve is a characteristic shake development where a curve has framed with an opening underneath. Regular curves ordinarily shape where inland bluffs, waterfront precipices, blades or stacks are liable to disintegration from the ocean, streams or enduring (subaerial forms).

Answer:
E2F transcription factors
Explanation:
The E2F transcription factors (TFs) encode intracellular factors associated with the control of the cell cycle. E2F are TFs that bind to promoter consensus sequences in order to activate transcription. These TFs control the expression of target genes involved in cell proliferation including, among others, genes for DNA replication and mitotic activation. Moreover, the E2F proteins also may act as a link between cell fate and the cell cycle. The retinoblastoma (Rb) is a protein that modulates the activity of the E2F family of TFs, and it has been shown that the Rb/E2F pathway is a key molecular mechanism associated with cell proliferation.
weathering takes it away
erosion builds up
Deposition is the geological process in which sediments, soil and rocks are added to a land form or land mass. Wind, ice, water, and gravity transport previously weathered surface material, which, at the loss of enough kinetic energy in the fluid, is deposited, building up layers of sediment.
the answer is deposition HOPE THIS HELPS
