Answer:

Codominance

Explanation:

This is an example of codominance.

Basically with this type of genetics, both alleles for that trait, in this case feather color, are dominant. This means that both will appear in the phenotype, instead of a dominant phenotype overshadowing a recessive phenotype.

Here, the two dominant alleles are the one that governs white pigment and the one that governs black pigment. Since codominance is occurring, we see a speckled chicken instead of just an entirely white one or an entirely black one.

Hope this helps!

Genetic variety in organisms is created through C) Meiosis. mitosis is a stage of the cell cycle and asexual reproduction occurs between only one parent, so not much variety. Cell fission is a form of asexual reproduction in bacteria, archaea, and other unicellular organisms such as diatoms and protozoans.

Answer: the law of conservation of energy.

This law applies to isolated system and means that the total energy in a given frame of reference is conserved over time. Its not created or destroyed and can only be converted from one form to another.
The conservation of energy can be proven by the Noether theorem.

Answer:

In muscle cell, fermetation produces "lactate and NAD"

In fermentation Pyruvate is reduced and __NADH__ is oxidized.

Explanation:

Muscle cells perform lactic acid fermentation when enough oxygen is not available to support aerobic cellular respiration. The process of glycolysis forms two molecules of pyruvate from one glucose molecule and uses NAD+ as electron acceptor. During lactic acid fermentation, pyruvate is reduced into lactate and NADH serves as an electron donor. The final products are lactate and NAD+. The reaction is catalyzed by lactate dehydrogenase enzyme. The NAD+ produced by fermentation is required to continue the process of glycolysis.
