???? what is you talking about
Answer:
True
Explanation:
<em>The life cycles of sexually producing organisms generally involve alternation between the haploid and diploid generations.</em>
<u>Sexual reproduction involves the fusion of gametes - fertilization. The gametes are haploid (n) and are usually formed by the reductional division (meiosis) of diploid (2n) sex cells. </u>
Haploid gametes represent the haploid stage of the life cycles of sexually reproducing organisms. During fertilization, the male and female gametes fuse together to form a diploid zygote. The zygote then continues to divide equationally (mitosis) and differentiates to give rise to a baby and eventually to either male or female adult organism.
Answer: Option A.
Electrons,carbon and energy.
Explanation:
Chemorganoheterotrophs are organisms that uses organic substrates to produce carbon needed for their growth and development. They derive their energy from oxidation and reduction of organic substances. The use the reduced carbon produced by autrotophs as as source of electrons, carbon and energy. Example is fungi that uses carbon as electron donor and source for carbon and energy.
