Answer:
The correct option is E: Limulus - Book Lungs
Explanation:
The structure of a book lung is made so as to maximize the efficiency of gaseous exchange in arachnids. An externally located structure, book gills, aids in this process. Limulus are horseshoe crabs that still makes use of book gills. Its a marine creature (an arthopod, to be specific) that has 5 pairs of book gills on its body.
Answer:
In eukaryotes, recombination during meiosis is facilitated by chromosomal crossover. The crossover process leads to offspring having different combinations of genes from those of their parents, and can occasionally produce new chimeric alleles. The shuffling of genes brought about by genetic recombination produces increased genetic variation.

Answer:
receptor-mediated endocytosis
Explanation:
- A selective mechanism that is responsible for endocytosis and transcytosis of the small amounts of materials that are present in the extracellular fluid is known as receptor-mediated endocytosis.
- The various molecules that can be taken up by this process include hormones, metabolites, proteins as well as certain viruses.
- This process is also known as clathrin-mediated endocytosis.
- In this process, the receptors that are present on the surface of the proteins are captured by a molecule which is the target site for the protein and internalized by membrane internalization (endocytosis).
- The vesicle formed by endocytosis is a clathrin coated vesicle.

Drinking alcohol and using drugs are common means used by the people to escape from self awareness. One cannot be conscious after drinking alcohol or taking drugs.
If someone does not wants to face the reality and live in his virtual world then he should drink alcohol and take drugs.
