Notes:
Cinnamon is obtained from the inner bark of cinnamon trees. Specifically, the bark is peeled off during the rainy season when it is still moist and flexible. After being removed, the bark is processed and dried to produce the spice we recognize as cinnamon.

Notes:
Rhizobium Found in roots of legumes, like Peas, grams, Pulses etc, where it fixes atmospheric nitrogen as ammonia, which is then converted into useful amino acid.

Notes:
Epinephrine which is also known as adrenaline, is a medication and hormone. It is used to treat a number of conditions, including cardiac arrest, anaphylaxis, , asthma, and superficial bleeding.

Notes:
Each adrenal gland is located on the top of each kidney (forming a hat-like structure on the top of the kidneys). Each adrenal gland has two parts viz. outer cortical portion and inner adrenal cortex. Further, there is a central part called adrenal medulla.

Notes:
Bombay Blood Group is an extremely rare ABO group, called so because it was first discovered among some people in Bombay. Their red cells lack ABH antigens and their sera contain anti-A and anti-B and anti-H. The anti-H would not be detected in the ABO group but would be detectable in pretransfusion tests. People who have Bombay phenotype can donate to any member of the ABO blood group system (unless some other blood factor gene, such as Rhesus, is incompatible), but they cannot receive any member of the ABO blood group system`s blood (which always contains one or more of A and B and H antigens), but only from other people who have Bombay phenotype

Notes:
First option is the correct answer
Symbiotic relationships are a special type of interaction between species. Sometimes beneficial, sometimes harmful, these relationships are essential to many organisms and ecosystems. Mutualism is when both  organisms involved are benefitted.  

Notes:
Apomixis is reproduction where only one parent passes genes to the offspring. Apomictically produced offspring are genetically identical to the parent (clones). The method is most seen in plants, especially flowering plants. Brambles (blackberry) are apomictic. Some authorities give “reproduction by special tissues without fertilisation”, or “asexual formation of a seed from the maternal tissues of the ovule, avoiding meiosis and fertilization, leading to embryo development”. (Wikipedia Simple)

Notes:
The primary route in which the body eliminates substances is through the kidneys. The main function of the kidney is the excretion of body wastes and harmful chemicals into the urine.

Notes:
A noncommunicable disease (NCD) is a medical condition or disease that is by definition non-infectious and non-transmissible among people. Eg. Cancer which is also called malignancy, is an abnormal growth of cells.

Notes:
Test tube baby is a term that refers to a child that is conceived outside the women’s body by a scientific process known as In-Vitro fertilization or IVF treatment. This entire process is done in a laboratory. In this process the eggs are taken from the mother’s ovary and fertilised by the sperms from the father.
Then the fertilized eggs are cultured for two to six days and allowed to be divided two to four times inside a test tube, thus the name test tube baby. These eggs are then implanted back into the uterus of a mother where it can develop normally. This is done with the sole intention for establishing and ensuring a successful pregnancy.
