Organisms, like bacteria or lichen, that can live on bare rock and form soil are called Pioneer species. In primary succession pioneer species like lichen, algae, bacteria , fungi as well as other abiotic factors like water and wind, start to normalize the habitat. This type of successions begins on rock formations, such as mountains or volcanoes, or in a place with no organisms or soil.
The world’s deepest lake is Lake Baikal in Russia. And you’ll find there the <span>Baikal seal, Lake Baikal seal or nerpa.

Answer:
E. HER3, but not HER2 binds to its ligand, causing it heterodimerize with HER2. This activates HER2 tyrosine kinase which creates a GRB2 binding site.
Explanation:
The receptor tyrosine-protein kinase, also known as human epidermal growth factor receptor 3 (HER3), is a transmembrane tyrosine kinase receptor that doesn't have a kinase domain. HER3 binds to the HER2 protein (another receptor tyrosine kinase receptor) to form a heterodimeric complex. Conversely to the HER3 protein, HER2 lacks a ligand-binding domain. The HER2/HER3 complex triggers the activation of the HER2 kinase domain which then autophosphorylates and thus generates a binding site for the Growth factor receptor-bound protein 2 (Grb2).
Adenine, guanine, thymine, cytosine. Thymine matches with adenine and cytosine matches with guanine
