<span>The mountains were once seas. The land was forced up by tectonic motion when the mountains were formed. The Sahara also used to be a sea and has a valley full of the fossilized remains of an extinct species of whale. It is generally agreed upon that two plates colliding caused the uplift that created the mountainous zone. Same for the Himalayas.</span>

Answer:
B) MALT or mucosa-associated lymphatic tissue
Explanation:
Lymphatic nodules are the secondary lymphatic tissues that lack any surrounding capsule and are present like egg-shaped tissue masses. The lymphatic nodules present in the lining of some organ systems such as gastrointestinal tract, urinary system, and the respiratory airways are called mucosa-associated lymphatic tissue (MALT) as these lymphatic tissues are present in their mucous membranes.
For example, Peyer patches and tonsils. Peyer's patches are the lymphatic nodules present in intestinal wall, and the appendix. Tonsils are the secondary lymphatic tissues present in a ring about pharynx.
Answer:
A. Left ventricle; systemic
Explanation:
The ventricles are located on the posterior end of the heart beneath their corresponding atrium. The right ventricle helps to receives deoxygenated blood from the right atria and pumps it through the pulmonary vein and into pulmonary circulation, then transported into for gas exchange via the lungs.
The left ventricle receives oxygenated blood from the left atria and pumps it through the aorta into systemic circulation in order to supply the tissues of the body with oxygen.
The walls of the ventricles are the thickest and strongest. This is because the amount of work on the left ventricles, which pump blood throughout the body and lungs, is much greater than the pressure generated by the atria to fill the ventricles.
