Answer:
Brachial vein.
Explanation:
Veins may be defined as the blood vessels that carries the blood towards the heart. The main function of the vein is to carry the deoxygenated blood into the heart.
Brachial vein is the deep veins that has the name as their arteries occupy. The brachial veins receive their blood from the palmar veins with the interosseous vein. The brachial veins include the ulnar vein, radial vein in upper limb and lower limb consists of popliteal veins.
Thus, the answer is brachial veins.
Answer:Atoms of nonmetals have a tendency to gain or share electrons when they react.
Explanation: Non-metals are elements that gain electron to form negatively charged ions known as anions.
When non-metals react, they either gain/accept electron from a metal atom or share electron with another non-metal atom. When a non-metal accepts an electron from a metal atom, the type of bond formed is called ionic or electrovalent bond. In electrovalent bond, the metal atom transfers its valence electrons to the non-metal atom so that both attain a stable octet or duplet structure.
When a non-metal shares electron with another non-metal atom, the type of bond formed is known as covalent bond. In covalent bond, the two non-metal atoms share a pair of electron, each atom donating one electron to form a pair.
Environmental scientists are using GPS ( It is effective but expensive) aerial monitoring (Quick but not the easiest), RFID tags, (mostly for long-term monitoring) and hidden cameras are used to study polar bear behavior without interruption to their environment.
Answer:
For the eggs to survive and have a chance of hatching, sea turtles must lay their eggs on sandy beaches. As they are developing, the embryos breathe air through a membrane in the eggs, and so they cannot survive if they are continuously covered with water.
