Scientists studying climate change have found that the effect of global warming is not only a higher planetary temperature, but also a universal change in seasons, specifically earlier springs and later autumns. Though some argue that this is an advantage because it presents a longer summer growing season, others fear that too many animal species will be unable to adapt and will become extinct. Which of the following is the best piece of evidence to support the conclusion that a longer growing season will hasten the extinction of some animal species?A. Squirrel and chipmunk species are unable either to consume or to store all the nuts and berries produced during a longer growing season. B. Fungus species typically produce spores only once a year and are unable to produce enough spores to release spores again before the end of a longer growing season. C. Butterfly species that respond quickly to changes in temperature hatch caterpillars and undergo metamorphosis into butterflies earlier, flying away before bird species that feed exclusively on them have hatched their young. D. Salmon species that rely on changes in temperature to signal the start of annual migrations leave their freshwater birthplaces earlier, before they have fed sufficiently on freshwater insects to reduce their number.\E. Reptile species that hibernate during winter months must emerge from hibernation sooner and spend a longer time searching for food before mating in mid-summer.

this protocol provides a detailed procedure for total protein extraction for western blot analysis from achieved samples following trizol isolation of rna.

metamorphism is the change of minerals or geologic texture (distinct arrangement of minerals) in pre-existing rocks (protoliths), without the protolith melting into liquid magma (a solid-state change). the change occurs primarily due to heat, pressure, and the introduction of chemically active fluids. i hoped i !

i wish i could with all of them i can barley see the first one so here's the answer to the first one b

1. amino acid refers to the fundamental building block of proteins, comprising of an amino group and a carboxyl group.

2. catalyst refers to any substance, which increases the rate of chemical reaction without being used up in the reaction.

3. a complex molecule containing he genetic code is dna or deoxyribonucleic acid.

4. an enzyme refers to a molecule of protein, which is unique in accelerating up a particular chemical reaction in the biological systems.

5. nucleic acid refers to an sequence of sugars, phosphates, and nitrogenous bases, for example, dna and rna.

6. a protein refers to a large, composite organic molecule comprising of a huge number of amino acids associated together with the of peptide bonds.

7. rna refers to a nucleic acid that takes part in the production of proteins.

8. substrate refers to a compound, which takes part in a chemical reaction, and is chemically modified by the reaction.
