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.
Surprisingly chocolate actually contains a fair amount of iron. Red meats are known to contain iron, one thing in particular is blood (yes that is sometimes eaten, and it contains a lot of iron). Such organs of animals that are high in iron include the spleen and or marrow.
If you wish to go vegetarian red veggies tend to be high in iron, one in particular are beets (yes, i know, they aren't red until processed)

<em><u>Crude oil, coal, wind and natural gas are all primary energy sources. Electricity is not a primary energy source, it's an energy currency (see electricity as an energy currency for an in depth discussion). Likewise, secondary fuels are also energy currencies and aren't primary energy sources, they must be made.</u></em>
Explanation:
%DV label= 27%
1 cup of cooked collared greens= aprx 266.60 mg of Calcium
Assuming Clara is...
- a teen, her required adequate intake (RAI)= 1300 mg/ day
- an adult, her RAI= 1000 mg/day
For teenaged Clara
∵27 % DV= 270mg
% daily Calcium= 
= 20.8 ≈ 21%
=0.21
<u>21% of her daily calcium needs is in a cup of cooked collard greens.</u>
Calcium is an essential mineral required by the human body, it is involved in cell signalling, muscular function and homeostasis. Along with fats, fiber, vitamin A and C and iron, calcium makes up part of a recommended daily intake target or DV- these are integral to a balanced diet.
