the process of photosynthesis converts the energy from sunlight into the chemical energy stored in what bonds

Answers

organic molecules e.g(sugar)


Final answer:

The process of photosynthesis converts light energy from the sun into chemical energy, primarily stored in the bonds of glucose. This occurs in two stages, the light-dependent and light-independent reactions, using ATP and NADPH as intermediate energy carriers. The glucose can be further metabolized to drive cellular processes.

Explanation:

The process of photosynthesis converts the energy from sunlight into the chemical energy stored primarily in the bonds of glucose, a simple sugar. This occurs in two main stages: the light-dependent and the light-independent (or dark) reactions. During the light-dependent reactions, energy from sunlight is absorbed by chlorophyll and converted into chemical energy stored in molecules of ATP (adenosine triphosphate) and NADPH (nicotinamide adenine dinucleotide phosphate).

These energy-laden molecules are then used in the light-independent reactions to convert carbon dioxide from the air into glucose. This process resembles 'recharging' the energy in the morning to be spent throughout the day. Ultimately it takes 18 molecules of ATP and 12 molecules of NADPH to synthesize one molecule of glucose, a total of energy equivalent to approximately 54 ATP molecules.

This glucose molecule can be further combined with or converted into other types of sugars. When the sugars are consumed by cells, the glucose is broken down through a series of complex reactions to extract the energy stored within it. This harvested energy is again stored in ATP molecules, which serve as the primary 'energy currency' within cells to perform various essential tasks.

List four different types of evidence that support evolution. Name and explain them.

Answers

Answer:

the explanation is in the answer...

Explanation:

Anatomy. Species may share similar physical features because the feature was present in a common ancestor (homologous structures).

Molecular biology. DNA and the genetic code reflect the shared ancestry of life. DNA comparisons can show how related species are.

Biogeography. The global distribution of organisms and the unique features of island species reflect evolution and geological change.

Fossils. Fossils document the existence of now-extinct past species that are related to present-day species.

Direct observation. We can directly observe small-scale evolution in organisms with short lifecycles (e.g., pesticide-resistant insects).

Describe a similarity and a difference between meiosis and mitosis

Answers

Answer:

The difference between mitosis and meiosis is that....

Mitosis produces two daughter cells with the same number of chromosomes as the parent cell.

Meiosis results in four daughter cells harboring only half of their parent's chromosomes, which underwent recombination.
