Answer:
a.Many mitochondrial genes resemble proteobacteria genes, while the genes in the chloroplast resemble genes found in some photosynthetic bacteria.
c.Mitochondria and chloroplasts both have their own circular DNA and 70S ribosomes that are similar to those found in bacteria.
d.Mitochondria and chloroplasts replicate by a process similar to mitosis.
Explanation:
Endosymbiotic theory states that mitochondria and chloroplast which are organelles of eukaryotic cells were once independently living micro-organisms but with due course of time eukaryotic cells engulfed them and they become an integral part of these eukaryotic cells.
The resemblance between mitochondrial genes with those of proteobacteria and chloroplast genes with photosynthetic bacteria strongly support endosymbiotic theory. Apart from this, the presence of their own DNA that too circular just like prokaryotic microbes and 70 S ribosomes also support this theory. Also just like prokaryotic cells, before cell division mitochondria and chloroplasts undergo replication by means of a process known as binary fission.
A nucleus. Hope this helps.
<span>The deposition of heavy sediment can significantly diminish the water quality and aquatic habitat. The sentiment in the water can reduce the sunlight that reaches the floor of the waterway, affecting animal and plant life. For example, photosynthesis may be less effective due to the decreased sunlight and the gills of fish may get clogged from the sediment.</span>
Hey You!
I believe the correct answer to your question is: Endangered Species. (Also called threatened species).
I Really Hope This Helped You, Good Luck With Your Studies! =)
Genetic change in the reproductive cells of the body (ovule or sperm) that is incorporated into the DNA of each cell in the body of the descendants. Hereditary mutations are transmitted from parents to children. It is also called germline mutation.
