Answer:
Option D, Gastric Juices
Explanation:
The second line of defense is a non specific defense mechanism in which no specific individual is targeted but all invaders are killed in general way. Some common mode of second line of defense are - Phagocytic cells (white blood cells), inflammatory responses, macrophage system etc. The second line of defense comes into action when the invader has surpassed the first line of defense which include either physical barrier like skin, mucous membrane, hair, cilia etc. or chemical barriers like gastric juices, saliva, Hyaluronic acid etc.
Hence, gastric juice does not belong to second line of defense.
Thus, option D is correct.

Scientists often experiment with Brassica plants because they have a relatively short growth period, and they may represent model organisms for genetic studies.
<h3>Why use the Brassica plants in genetic studies?</h3>
Brassica plants are considered model organisms in genetic studies because they have a short period of growth (around 30 days), which allows the analysis of a high number of generations in less time.
Moreover, the genome of Brassica plants contains 24 Gigabases (24 billion nucleotide bases), which is a high number to be considered a model organism in genetic studies.
In conclusion, scientists often experiment with Brassica plants because they have a relatively short growth period, and they may represent model organisms for genetic studies.

An Rh negative individual does not contain anti Rh antibodies. Rh- antibodies only develop in cases of pregnancy, miscarriage or a blood transfusion like if you have Rh-negative blood you got AB blood. The Rh-antibodies then work to attack the foreign substance, the RBCs. In the fetus, loss of RBCs means the rise of bilburin and could eventually lead to brain damage and also have low muscle tone.
