Answer:
The carbon atom used to build carbohydrate molacules come from carbon dioxide, the gas that animals exhale with each breath. The Calvin cycle is the term of used for the reaction of photosynthesis that use the energy stored by the light dependent the reaction ot form glucose and other carbohydrate molacules.
Answer:
it's a molecule
Explanation:
if it was just hydrogen it would be an atom, but when you add another element it becomes a molecule.
<span>The statement, “fruits develop from ovary walls,”
does not describe the nature of fruits accurately. Fruits are the reproductive
organs of plants just like the flowers and the seeds. They are mature ovaries
of the plants that serve as an important factor in perpetuating its species.
These mature ovaries encapsulate more seeds inside that promote germination.
They are an important source of dietary fibers and nutrients that are body
needs, particularly vitamin c. Through modern technologies fresh fruits can now
be made into jams, juices, and jellies and can be preserved through canning,
picking, and fermentation. </span>
Fossil records provide evidence of natural selection because one can see what species and what type of species (specifically what type of special trait the species had) reproduced and lived for longer.
For example, we have 5 different fossils of the same animal;
1. Lived about 45 years; had long legs that made it run faster - 5 offspring
2. Lived about 8 years; had short and stubby legs, was very slow - 0 offspring
3. Lived about 67 years; had long legs that made it run faster and a good nose - 8 offspring
4. Lived about 40 years; had a good nose and normal legs - 6 offspring
From all of that information you can see that the prefered trait was having longer legs and a good nose survived and reproduced multiple time, you can also see that the organism that had short legs did not survive for long and did not reproduce.
