Pyruvate is first converted to acetaldehyde by enzyme pyruvate decarboxylase in the presence of Thiamine pyrophosphate and Mg ++. Carbon-dioxide is released during this reaction.
With sexual reproduction a sperm coming from the male must unite with the female egg. Both are needed for this kind of reproduction, and an offspring CAN'T be formed without both. Unlike asexual reproduction, the offspring of a mammal reproducing sexually is DIFFERENT from both parents, since the offspring is a combination of both the mother and the father.
An easy to remember example I use when thinking about what sexual reproduction is:
the formation of a human child. A mother with her egg and the father with the sperm is BOTH needed. If you think about siblings that come from the same parents (and therefore same gene pool) they are not all exactly identical to each other. Although they may have similar features, they look different and are NOT genetically identical
Therefor for your question the answer is D.
Hope this helped!
Explanation:
Oxygenic photosynthesis is composed of two stages: the light-dependent reactions and the light-independent reactions. The light-independent reactions use the ATP and NADPH from the light-dependent reactions to reduce carbon dioxide and convert the energy to the chemical bond energy in carbohydrates such as glucose.
Answer:
Rr and rr
Explanation:
The genotypes of the parents would be heterozygous red (Rr) and true-breeding white (rr).
<em>Since the allele for the red flower color (R) is dominant over that of the white flower color (r), for a cross to produce both red and white flower color plants, the red parent must be heterozygous (Rr) and the white parent true-breeding (rr). </em>
Rr x rr
Rr Rr rr rr
Rr = red
rr = white
If the red parents is true-breeding
RR x rr
Rr Rr Rr Rr
All their offspring would be red without any white flower color.
Hence, the genotypes of the parent are Rr and rr.
