Answer: amylopectin and glycogen have the same kind of linkages, but glycogen has a higher frequency of αα-1,6'-glycosidic linkages
Explanation:
Amylopectin is one of the two main fraction of starch. It has several repeating units of glucose molecules linked by α-1, 4-glucosidic linkage, but has many side chains attached to the basic chain by α-1, 6-glucosidic linkages
Glycogen, as well, is a branched polysaccharide and resembles amylopectin very much in structure, but glycogen has more glucose residues per molecule and about one-half times as many branching points.

Protons and neutrons are energy particles found in the nucleus of atoms.
Explanation:
The forces that hold the protons and neutrons together in the nucleus are called strong nuclear forces. These forces are attractive over short distances and repulsive over long distances. This is why protons that are positively charged are held together in the nucleus despite their repulsive tendencies. However, as the nucleus gets larger because of the larger number of protons and neutrons in the nucleus, the distance with which the string nuclear forces are attractive is surpassed.
The binding energy in the nucleus will, therefore, be surpassed by the repulsive forces of strong nuclear forces over long distances causing the atomic nucleus to lose some neutrons.

Answer:
True
Explanation:
A muscle tissue get shortened only when the sarcomere changes structurally. Myosin form cross bridges with the actin as they head towards the thick filament. Myosin then pulls the thin filaments and shortens the sarcomeres thereby shortening the skeletal muscles. This process continues till the active sites on actin remain exposed and there is ample availability of calcium ion and ATP.
Hence, the given statement is true
Halley — the traditional pronunciation of the name usually rhymes with valley — was born Nov. 8, 1656, in Haggerston, Shoreditch, London, England. His father was a prosperous soapmaker and property owner. Halley was tutored privately at home before entering St. Paul's School, where he excelled in mathematics and astronomy.
Halley entered Queen's College, Oxford, in 1673, when he was 17 years old. He brought with him a fine collection of astronomical instruments purchased by his father. While still an undergrad, he became a protégée of John Flamsteed, the Astronomer Royal. Halley made important observations at Oxford, including an occultation of Mars by the moon, and published papers on the solar system and on suns
