Answer:
Any converging lens that has a small focal length (several centimeters) can be used as a magnifying glass. The observed object is placed in front of the magnifying glass so that it is located between the lens and the focus (closer to the focus).
Explanation:
It consists of only one condenser lens of small life (a few centimeters).
The observed object is placed between the magnifying glass and its focus (closer to the focus)
The observer sees an upright and enlarged figure of the object.
In order to like clear video ("sharpen"), the magnifier zooms in or out of the subject.
When the character is most clearly seen, we can find ourselves on a given high species.
For a man with normal eyesight, it is about 25 cm.
Answer:
Proteins are processed and modified in a successive manner to add or remove sugar as they move from cisterna to cisterna.
Explanation:
Golgi apparatus has a flat membrane disk in varies in number in stack, the number can be in between 3 to 20, however six is found in most of them. Cisternae can be separated in four classes cis, medial, trans, and TGN.
Proteins that come from the endoplasmic reticulum in cis type of cisternae after passed through cis to cis and move the protein in order to add or remove sugars to protein.
Thus, the correct answer is - Proteins are processed and modified in a successive manner to add or remove sugar as they move from cisterna to cisterna.

Answer:B6 and B12.
Explanation:
Homocysteine is an amino acid produced from demethylation of methionine.The later is an amino acid needed in the body which must be conserved.
In order to conserve it ,Homocysteine is recycled in a specific pathways which inovles activities of Vitamin B6 and B12
.Therefore deficiency of these vitamins leads to elevated levels of Homocysteine.
HIGH LEVELS OF HOMOCYSTEINE AFFECT THE ENDOTHELIAL CELLS ;LEADING TO ABNORMAL CLOTTING OF BLOOD.THIS INCREASE IN BLOOD VISCOSITY PUT THE HEART AT RISK OF CARDIOVASCULAR DISEASES.
