Answer: Option B
Explanation:
Large industries that is dependent on wind energy should be situated at the places where there is a consistent wind.
The areas where the wind is consistent is restricted to some places and due to this there is a limitation for the large industries using wind energy.
There is some localized area where these companies are set up to meet the requirement of wind.
It also requires windmills and other equipment which needs space to set up and so it cannot be just put anywhere to get energy out of it.

Sickle cell anemia is defined as a genetically inherited disorder that causes deformation of red blood cells (RBCs) and inadequate oxygen transport. It is caused by a mutation in the gene that encodes for hemoglobin and leads to formation of a defective protein.
The RBCs transport oxygen to the various parts of body with the help of hemoglobin molecules. Due to defective hemoglobin, blood cells become sticky and rigid, and shape like sickles. The resulting sickle-shaped cells get stuck in blood capillaries that block or slow down blood flow or oxygen transport to the body organs.
Thus, 'sickle cell anemia affects oxygen transport in the body.'
A genetic disorder in which the deformation of red blood cells occurs due to which transportation of oxygen is hindered is called sickle cell anemia.
Further Explanation:
The inherited form of anemia is sickle cell anemia. It is a condition during which the body contains an inadequate amount of red blood cells to fulfill the required supply of oxygen in the body. The normal red blood cells are round and flexible and move with ease through the blood vessels. The defective red blood cells during sickle cell anemia appear like a crescent moon and become sticky and rigid. These defective cells cannot pass the blood vessels and get stuck in between. It may lead to a stoppage and slow down of blood flow, which in turn also obstructs the passage of oxygen throughout the body.
The gene mutation is the cause of the anemia. This gene is responsible for the production of haemoglobin. Haemoglobin is an iron-rich compound which provides the blood with its red color. The red blood cells carry oxygen with the help of hemoglobin, which binds oxygen. Abnormal hemoglobin is produced during sickle cell anemia, which makes the red blood cells rigid and sticky.
These defective genes are passed from parents to the offspring and generate an inheritance pattern, which is called autosomal recessive inheritance. This means both the parents must transfer the defective allele to produce an affected child. If a person inherits a sickle cell gene from only one parent, he/she is a carrier of the disease. This implies that the person can further pass on the gene to his/her progeny.

b. Carbon monoxide and sulfur oxides are common air pollutants.
c. Natural components of air, like carbon dioxide, cannot be considered air pollutants.
d. Primary and secondary pollutants are harmful to human health and the environment.
Answer: c) Natural components of air, like carbon dioxide, cannot be considered air pollutants.
Explanation:
Carbon dioxide plays a role as greenhouse gas. Though living being emit carbon dioxide when they breathe, carbon dioxide is considered as a pollutant when associated with cars, power plants, and other human activities that involve the burning of fossil fuels such as gasoline and natural gas.
B. Transcription can begin as soon as translation has assembled the first few amino acids in the polypeptide.
