Answer 1

Answer:

Iron is an essential element for blood production. About 70 percent of your body's iron is found in the red blood cells of your blood called hemoglobin and in muscle cells called myoglobin. Hemoglobin is essential for transferring oxygen in your blood from the lungs to the tissues.

Iron deficiency anemia is a common type of anemia — a condition in which blood lacks adequate healthy red blood cells. Red blood cells carry oxygen to the body's tissues. As the name implies, iron deficiency anemia is due to insufficient iron.

Snakes kill animals like rats that damage food crops. As they prevent the destruction of food crops that a farmer grows for his livelihood and hence snakes are farmer's friend.

Snakes do not have external ears and thus, they can't hear like how we hear the sound. ... Snakes have a hearing organ inside their head, which is connected with their jaw bones. This is called a vestigial (undeveloped or immature) organ. Snakes can detect vibration of any sound by this hearing organ.
