The Suns energy enters the food chain, but the food is energy itself for the predators etc.
Hope this helps
Answer:The contrast of the difference between what is called "microevolution", and "macroevolution".
Microevolution concerns the transformation of traits in a population of a given species.
Macroevolution concerns evolution above the species level: it includes the diversification of high level taxa, (mass) extinctions, origin and diversification of clades, etc.
Speciation – the arising of new species, and the main processes likely to produce it stands at the boundary between those evolutions.
Notably, when people of the term "evolution" they typically think of macroevolution (think of Darwin's focus on species their origins and transformation).
Darwin's focused on species their origins and transformation.
Darwin on evolution proposed natural selection as the mechanism of evolution
- Note these important points he outlined:
• Individuals do not evolve: populations evolve
• Natural selection can amplify or diminish only heritable traits; acquired characteristics cannot be passed on to offspring
• Evolution is not goal directed and does not lead to perfection; favorable traits vary as environments change.
Explanation:
A. If the optimum temperature for a cell's functions is exceeded, chemical reactions slow down as enzymes and other proteins begin to denature (change shape due to increased vibration of the atoms in the molecules that make up the proteins).
The types of amino acid r groups will line the channel protein interior would be non-polar.
On the interior side of the system, there are non-polar amino acids that can form bonds with the hydrophobic tails of phospholipids inside cell membrane structures. By using the phenomenon of passive diffusion, they perform the fundamental task of moving materials across the membrane. The amino acid glycine contains an R group, as is the case. Valine, methionine, and alanine are a few of the non-polar amino acids, as are others.
Amino groups are more prevalent than carboxylic groups in polar amino acids with a positive charge. A more basic amino acid then results. On the "R" group of these amino acids, there is a positive charge. Lysine, arginine, and histidine are some examples of compounds that fall under this category.

The answer is a. duplicate its genetic information, this happens in the S phase of interphase. You're welcome, want more info on cytology, just ask.
