Cell Y.
Answer: Option C.
<u>Explanation:</u>
Prokaryotic cells are the cells that do not possess a true nucleus. They do not even possess a membrane bound organelles. Organisms with in the domains bacteria and Archaea have prokaryotic cells. The other forms of life are the eukaryotic.
It is a unicellular organism. The word prokaryotic comes from a Greek word. The prokaryotic cells have a cell membrane or a plasma membrane which acts like a protective shield. Along with this, they also have a rigid cell wall which acts like further support and protection.
Explanation:
This situation is called an incomplete dominance. A great example of this is when a plant with red flowers is paired with a plant with white flowers and the seeds give plants with pink flowers

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).
