Reflection and absorption…depends on the reaction of the wave and the barrier in question. A barrier could cause the wave to bounce right off or it could suck it right in.

The antebrachial region is the forearm. chest area. lower back. area in front of the elbow. bottom of foot.
mylen [45]

The antebrachial region is the forearm.

The antebrachial region is a term used in anatomy to refer to the inner forearm. The forearm refers to the region of the arm which connects the elbow and the wrist.

This region consists of two bones i.e. the ulna (medially) as well as the radius (on the lateral side).

The elbow joint is created by the connection between the trochlea of the humerus and the trochlear notch of the ulna, including the connection between the capitulum of the humerus and the head of the radius.

The medial cutaneous nerve of the forearm, also termed as the medial antebrachial cutaneous nerve, is an offshoot of the medial cord of the brachial plexus.

Can someone please answer 15-17
yan [13]

Answer:

15. D have specific gened activated

16. G cell division is unregulated

17. D providing information to form proteins

Explanation:

15. When an egg is first fertilised, the cells are very flexible. They are sort of like a "blank slate", and can become any type of cell. From these cells, all the cells in the body are created: brain cells, skin cells, blood cells etc. To become all these different types of cells, they keep dividing, slowly branching off and becoming more specific. This process is called differentiation.

They do this because different patterns and combinations genes are activated that turn them in to these different and specific cell types.

16. One of the hallmarks of a cancer cell is unregulated cell division. Oncogenes start as normal genes (called proto-oncogenes) that function in normal processes, such as the cell cycle, inhibiting apoptosis. However, when they become mutated, they can promote the growth and division of cells and prevent their programmed death. This is because they become more active or present in higher amounts following the mutation. This causes such functions in the cell to become deregulated, leading to uncontrolled cell proliferation and the growth of harmful tumour cells.

17. The central dogma of biology states that DNA --> RNA --> protein. The messenger RNA (mRNA) is transcribed from the DNA. It contains a message that is translated by the protein synthesis machinery to form proteins.

This is how all the proteins in the cell are produced, and the information for how to encode them is entirely dependent upon the sequence of the DNA, which is sent as a coded message in the form of RNA, to the protein synthesis machinery. The protein synthesis machinery makes the proteins according to the DNA sequence (as translated from the mRNA).
