Pick out an animal which has four chambered stomach _______
- A.
  
  Elephant
- B.
  
  Dolphin
- C.
  
  Deer
- D.
  
  Kangaroo
Correct Answer
C. Deer

Explanation
Deer is the correct answer because it is a ruminant animal that possesses a four-chambered stomach. The four chambers of the deer's stomach allow for a more efficient digestion process, as they enable the deer to regurgitate and re-chew their food multiple times, aiding in the breakdown of tough plant material. This adaptation is necessary for herbivorous animals like deer to extract as many nutrients as possible from their diet.

Mitral valve is found between _________
- A.
  
  Right auricle and right ventricle
- B.
  
  Left auricle and left ventricle
- C.
  
  Right ventricle and pulmonary artery
- D.
  
  Left ventricle and aorta
Correct Answer
B. Left auricle and left ventricle

Explanation
The mitral valve is found between the left auricle and left ventricle. This valve ensures that blood flows in one direction from the left atrium to the left ventricle, preventing any backflow. It consists of two flaps, or leaflets, that open and close synchronously with the heartbeat, allowing blood to pass through when the ventricle contracts and closing to prevent regurgitation when the ventricle relaxes. The correct answer, "Left auricle and left ventricle," accurately identifies the location of the mitral valve in the heart.

Quills are specialized hairs found in certain mammals, like porcupines, that serve as a defense mechanism by detaching easily and embedding into predators.

Explanation
The kidneys play a crucial role in maintaining the chemical composition of blood. They filter out waste products, excess water, and electrolytes from the bloodstream, ensuring that the levels of these substances remain within a normal range. Additionally, the kidneys help regulate the balance of acids and bases in the blood, which is essential for maintaining proper pH levels. Through their filtration and regulatory functions, the kidneys help to maintain the overall chemical balance in the body, making them the master chemists of our body.
