<h2>The difference between a chemical reaction and a nuclear reaction is that a nuclear reaction releases more energy per gram and appears to
violate the law of conservation of mass.</h2>
Explanation:
- Both chemical and nuclear reactions undergoes energy changes.
- In nuclear reactions, the energy changes are massive and measurable compared to a chemical reaction where the changes are not detectable.
- During a nuclear reaction, the total mass of the products is not equal to the total mass of the reactants and hence violates the law of conservation of mass.
- Like in a nuclear fusion reaction between hydrogen nuclei to form helium nuclei, the total product mass is not equal to that of reactants since some mass is converted to nuclear energy.
- However, during chemical reactions, the law of conservation of mass is not violated.
Answer:
All angiosperms produce flowers, reproductive structures that are formed from four whorls of modified leaves. Most flowers have showy petals to attract pollinators, bribing insects and other animals with nectar, to get them to carry the male gametophyte through the air to another flower.
Answer;
-The first antibody is specific for the primary amino acid sequence of TT, whereas the second is specific for conformational determinants.
Explanation;
-Antigen-antibody reaction, is a specific chemical interaction between antibodies produced by B cells of the white blood cells and antigens during immune reaction.The specificity of the binding is due to specific chemical constitution of each antibody.
-The amino acid sequence in the tips of the "Y" varies greatly among different antibodies. This variable region, composed of 110-130 amino acids, give the antibody its specificity for binding antigen. The variable region includes the ends of the light and heavy chains.
