Answer:
Explanation:
Haemoglobin in the red blood cells which is one of the components of the circulatory medium, the blood, has a great affinity for oxygen hence transports it around the body during circulation. It is the circulatory system that carries both oxygenated and deoxygenated blood around the body, between the lungs and the heart. The circulatory system takes blood with carbon dioxide to the lungs where oxygen that entered into the body through the nostrils will be exchanged with carbon dioxide in the alveoli. Consequently carbon dioxide will go out of the body through the nostrils via the trachea and haemoglobin in the red blood cells in the blood( blood capillaries) will
carry oxygen which is transported around the body.
Answer:
c) The presence of an ephiphyseal line
Explanation:
The options should be:
a) the presence of osteoblasts
b) the presence of osteons
c) The presence of an ephiphyseal line
d) the presence of hyaline cartilage on the ends of the bone
Explanation:
In vertebrates, the epiphyseal line is formed once the bone is completely grown. This occurs inside a plate known as the epiphyseal plate.
From the age of 18 to 21, the bone stops growing and the cartilage inside this plate gets replaced by bone. However, bones can keep growing in width until we are approximately 25 years old.
Therefore, the physical sign that indicates that a bone cannot continue longitudinal growth would be the presence of an ephiphyseal line.
Answer:
Other helpful techniques include planting more drought-resistant strains of corn and wheat; leaving crop residue on the fields to cover the soil; and planting trees to break the wind.
The material that makes up the membrane cell is the phospholipids, cholesterol, proteins, and carbohydrates.
