The more energy needed, the higher the melting point or boiling point . As metals are giant lattice structures, the number of electrostatic forces to be broken is extremely large, and so metals have high melting and boiling points.
i would go with true.
Answer:
Fasting can definitely raise blood glucose. This is due to the effect of insulin falling and the rising counter-regulatory hormones including increased sympathetic tone, noradrenaline, cortisol and growth hormone, in addition to glucagon. These all have the effect of pushing glucose from liver storage into the blood. This is normal. If you are not eating, you want to use some stored glucose. The question is this – if you are not eating, and your blood glucose went up, where did that glucose come from? It can only have come from your own body (liver). So, it’s a natural phenomenon, and the fasting now allows your body to use some of the glucose for energy.
Pepsin is one of three principal protein-degrading enzymes in the
digestive system, the other two being chymotrypsin and trypsin. During
the process of digestion, these enzymes collaborate to break down
dietary proteins to their components, i.e., peptides and amino acids.
Answer:
Genetics is a branch of science that deals with the study of genes, their sequence, function, variation, and heredity.
Increasing understanding of genetics help in making new fields of health care, for example,
- Gene therapy helps in treating various genetic diseases such as cystic fibrosis et cetera.
- Molecular genetics help in the development of more precise methods for diagnosis such as ELISA.
- Pedigree analysis and karyotypes help in early detection of possible hereditary diseases.
- DNA fingerprinting helps in detecting criminal suspects, paternity test, identification of dead organism et cetera.
