Answer: <span>A) Slow to repopulate
------
Genetic variation is an advantage of sexual reproduction. It increases survival and the ability to adapt in a species. Species with genetic variation can respond better to environment changes, since the genetic variability allows some to be immune to disease or adapt better to a change, and live to reproduce.
Slow to repopulate is a disadvantage because the species cannot recover quickly after a large disaster. It also means they cannot adapt as quickly to an environmental change.</span>
Poaching refers to the illegal hunting of wild animals in violation of the laws which regulate hunting of wild animals. Over utilization refers to the exploitation of an animal to the point of extinction. Poaching activities include hunting and killing wild animals without licence, using illegal weapons to kill animals, killing animal out of season, etc. All these activities can lead to drastic reduction in the population of animal specie to the extent that the animals become extinct. A good example of an over utilized animal specie is passenger pigeon.
Pathogens can exist in blood and then can be passed the transfusions
Answer:
Protein
Explanation
Ribosome and Rough E.R are organelles in the cell.
E.R are extensive membranes (which are continuous with the nuclear membrane) that exist as flattened compartment in the cytoplasm.These compartment form sacs in the cytoplasm. The sacs are interconnected with one another to form a complete system called the reticulum.
Based on structure two types of E.R exists -the Smooth E.R and the Rough Endoplasmic reticulum.The later is called rough because of Ribosomes attached to its outer membrane. the smooth lacks ribosomes attachment on its outer membrane. Ribosomes are the site of Protein synthesis in the cell.
They are small in number and are made up of RNA and protein.Generally the protein synthesised in the Ribosomes,are moved into the sacs in the R.E.R,where they are modified.They are eventually budded off in vesicles which form the Golgi bodies
