A. healthy ecosystem is a value of biodiverity
Answer:
True
Explanation:
Mitochondria is present in almost all the eukaryotes and it contains its own DNA as its genetic material which is double-stranded and circular. The gene located on mitochondrial DNA are inherited only by mothers to their offspring.
As the mitochondrial DNA is transported from the female ovum therefore only mother can transfer the mitochondrial DNA to their children however some theories say that even the paternal mitochondrial gene can be transferred to offspring under some specialized condition.
Therefore it is true that genes located on mitochondrial DNA are usually inherited by mothers in their offsprings.
In plants, photosynthesis, occurring in chloroplasts, is an anabolic (bond-building) process whereby CO2 and H2O combine with the use of light (photon) energy. This yields O2 and sugar (i.e. glucose). This occurs in 2 phases: light-dependent and dark (Calvin cycle) reactions, which both continually recycle ADP/ATP and NADP/NADPH.
The catabolic (bond-breaking) process in plants is cellular respiration, in which glucose is broken down with O2 by glycolysis (cytoplasm only) and mitochondrial reactions (Krebs cycle and E.T.C.) to yield CO2 and H2O. These reactions recycle ADP/ATP and NAD/NADH. The CO2 and water produced by cellular respiration feed into the photosynthetic processes, and in turn, the O2 and glucose resulting from photosynthesis supply the respiratory reactions.
50 chromosomes
A sperm cell is haploid (n) and a zygote is diploid (2n) so 25(2)=50 chromosomes
