Answer:
Explanation:These studies generally explore how insights gained from traditional unidimensional biodiversity research differ from those derived when multidimensional approaches are taken
Answer:
The ability to reproduce on land without needing external water. (Ans. A)
Explanation:
Internal fertilization is defined as the process where, sperm is fertilizing the egg within the female reproductive tract. Internal fertilization helping in to protects the fertilized embryo from harsh environment, predation, and they are able to reproduce on land without any need of external water, which results as higher survival rates.
This fertilization includes 3 main methods for fertilization:
1) Oviparity: In this fertilization eggs are placed outside the female body and nourishment of embryo comes from the yolk which is a part of the egg.
2) Ovoviparity: In this process eggs held within female and nourishment is comes from the yolk.
3) Viviparity: In this process development of embryo occurs within female followed by live birth and nourishment is received directly from the mother with the help of placenta.
In internal fertilization, fertilized eggs are protecting from dehydration on land this is the advantage of this method of fertilization.
Answer:
Prions are infectious agents which are responsible for neurodegenerative diseases in animals. Prions cause the refolding of the alpha helical and coil forms of protein structure into beta sheets.
Explanation:
The alpha sheets and coil structures assume <u>helical structures</u> and therefore would give different physiological properties to protein. When they are converted into beta sheets, which are <em>flat and parallel</em>, the structure and function of the protein get altered.
The cellular form of the protein is sensitive to proteases whereas the misfolded protein is <em>not affected</em> by proteases. The misfolded form perpetuates itself by causing the newly synthesized normal form of protein to become <u>degenerate</u>.
<em>Kuru</em> was the first disease caused by prion in humans.,
