Energy transformation is the process of transfer and conversion of energy from one species to another. None of the above is not an example of energy transformation. Thus, option D is correct.
Energy transformation is the process in an ecosystem that includes the conversion of energy from one level to another in the food chain or the metabolic reactions.
Photosynthetic reactions under the sun, herbivores feeding on producers, and predators feeding on the primary consumers are examples of energy conversion as it is continuously passing the energy to another species in the ecosystem.
Therefore, none of the above is not an example of energy transformation.

Answer:
D. None of the above
Explanation:
Answer and Explanation:
All cells including the gametes contain chromosomes. Each gamete cell after cell division contains 23 chromosomes. After fertilization, the diploid number of chromosomes which is 46 is restored in the zygote.
Meiosis, a type of cell division, has two phases which eventually lead to the formation of four daughter cells with equal number of chromosomes. Gametes are haploid in nature and thus meiosis I involves separation of homologous chromosomes hence the reduction in the chromosome number. Meiosis II involves separation of sister chromatids in the daughter cells resulting in four daughter cells with 23 chromosomes.
Meiosis ensures that chromosoe number does not double with each successive generation as the resulting daughter cells are gametes, two of which must fuse to form a zygote.

Answer:
A bright light close to the plant.
Explanation
Plants grown in bright light had higher rates of apparent photosynthesis per unit leaf area in bright light, and slightly lower rates in dim light than did those of plants grown in dim light. Dark respiration rates were higher in plants grown in bright light than in plants grown in dim light and the decline of photosynthesis with increasing leaf age was faster.
The rate of apparent photosynthesis in bright light of the first leaf to become fully expanded after plants were transferred from bright to dim light was lower than that of plants remaining in bright light. The decline in the rate of photosynthesis of a leaf already fully expanded at the time of transfer was not affected. Transferring from dim to bright light increased the rate of photosynthesis of the next expanded leaf; it also increased the rate of an already fully expanded leaf during the first week in bright light.
The possible blood type of offspring, when a woman with type O and a man who is type AB are expecting a child are A and B.
There are four kinds of blood groups which are A, B, AB, and O, based on the presence of antigens in RBC. Blood groups A and B show co-dominance, while O is recessive.
When a woman with type O blood and a man who is Type AB are expecting a child, the possible blood types are A and B. 50% of the children would have A blood type, and 50% of children would have blood type B, which are heterozygous.
When Parents are both heterozygous for the B blood group, then the possible blood group of offspring would be 75% B blood type (25% are homozygous and 50% are heterozygous) and 25% O blood type.
