Structure A is the mitochondria
Answer:
receptor-mediated endocytosis
Explanation:
- A selective mechanism that is responsible for endocytosis and transcytosis of the small amounts of materials that are present in the extracellular fluid is known as receptor-mediated endocytosis.
- The various molecules that can be taken up by this process include hormones, metabolites, proteins as well as certain viruses.
- This process is also known as clathrin-mediated endocytosis.
- In this process, the receptors that are present on the surface of the proteins are captured by a molecule which is the target site for the protein and internalized by membrane internalization (endocytosis).
- The vesicle formed by endocytosis is a clathrin coated vesicle.
Answer:
fish and tetrapods are both vertebrates that have a backbone with a spinal cord. fish lived before tetrapods because their fossils are in rocks over 500 million years old.

True there are temperate rainforests in Oregon, and other places
Answer:
UUU and UUC
Explanation:
Information that encodes certain functional products called PROTEIN are present in the DNA molecule. However, the information needs to be expressed via the processes of transcription and translation. Transcription is the synthesis of a mRNA using a DNA template.
The mRNA then undergoes translation, where it is read in a group of three nucleotides called CODON. Each CODON specifies a particular amino acid. Due to the degenerate nature of the genetic code, more than one codon can specify one amino acid.
Hence, in the case of phenylalanine amino acid, codons UUU and UUC both specify it. This means that whenever UUU and UUC are read during translation, a phenylalanine is added to the peptide chain.
