"C. Organisms' characteristics are carried <span> on DNA.</span>" would be the best fit, although this still isn't really the core idea behind natural selection, which is that animals survive based on how "fit" they are for their environment.

Explain the results of light dependent and light independent reactions
IRISSAK [1]

Hope this helps!

In the light-dependent reactions, energy from sunlight is absorbed by chlorophyll and that energy is converted into stored chemical energy. In the light-independent reactions, the chemical energy harvested during the light-dependent reactions drives the assembly of sugar molecules from carbon dioxide.

Is the ocean salty because the land never waves back?
timofeeve [1]
NO, the ocean is salty because it is the place where many of the salt from lakes and rivers leave off in. If this doesn't happen, then there will not be any fresh water, there will only be salty rivers, very salty rivers, not so salty rivers, or so salty to the point you can't even drink it salty water (lol)

When can an acquired mutation be passed from parent to offspring
Vitek1552 [10]
If the mutation takes place in a gamete that ends up forming an embryo, the mutation will be passed on to an offspring. This can also occur if the mutation occurs early in an embryos development, and the cell becomes one of the gamete forming cells, the mutation will be passed on to their offspring.

How many distinct stages must occur between the point when light first encounters chlorophyll and the point at which
Novay_Z [31]

Explanation:

<u>Three.</u>

Photosynthesis produces glucose and O2 from inorganic CO2, light energy and water.  This occurs in distinct steps: 1) light fixation,  2) electron transport and NADPH production 3)  ATP generation, then 4) carbon fixation and carbohydrate production.

6CO2 + 6H20 + (energy) → C6H12O6 + 6O2

Further Explanation:

Photosynthesis is a chemical process, essential to plant and other primary producers producing energy. As oxygen is emitted, energy in the form of glucose molecules is created from light, water, and carbon dioxide. It happens in several complicated stages, photosynthesis is a speed-limited process, depending on several factors including concentration of carbon dioxide, ambient temperature and light intensity; energy is extracted from photons, i.e. light particles, and water is used as a reduction agent. It occurs in the thykaloids, where pigment molecules live like chlorophyll.

Photosynthesis occurs in several complex steps and is a reaction of a small duration, depending on several fa factors including carbon dioxide concentration, ambient temperature and light intensity; the energy is retrieved from photons, I.e. particles of light, and water is used as a reducing agent. Water supplies the chlorophyll in plant cell with replacement electrons for the ones removed from photosystem II.

Additionally,

  • Water (H2O) divided into H+ and OH-by light during photolysis serves as a source of oxygen along with acting as a reduction agent; it reduces the NADP molecule to NADPH by supplying H+ ions and generates molecules of the energy storage molecule ATP through an electron transport chain.
  • This happens in the thykaloids, where pigment molecules reside like chlorophyll.
  • Later, NADP and NADPH are used in dark reactions during the Calvin cycle, where monosaccharides or sugars such as glucose are produced after several molecules have been modified. These store energy in their bonds which in the mitochondria can be released in respiration.
