RBC stands for Red Blood Cells. They are also called erythrocytes. They are circular, biconcave, disc-shaped and non -nucleated cells. They are formed in red bone marrows and destroyed in the spleen. Their lifespan is very short that is 4 months.

RBC contains an iron pigment called haemoglobin that carries oxygen from place to place in the form of oxyhemoglobin. When haemoglobin is exposed to oxygen, it turns red. So the blood is red in colour. If RBC is less in blood then, a person is suffering from anaemia , as there is not enough haemoglobin to transport oxygen.

Which of the following statements CANNOT be attributed to the spread of modern agriculture?
posledela

The correct answers are: II and IV.


''Single-family farms are making higher profits'' and ''mechanized farms require a larger labor force than traditional farms'' are the two statements that are not true about the modern day agriculture.

Single-family farms are not making higher profits, thy are in fact making much less profit, and especially in the developed countries this type of farms are systematically brought to minimum and are on the verge to stop existing.

Mechanized farms do not require larger labor force, totally opposite, they require much less labor force. The whole point of the mechanization is to lower the requirements for labor force and increase the speed and efficiency of the work, so this made it possible that much fewer people to be able to do much more work with the help of the mechanization.
