Answer:
The features of prokaryotes include circular DNA molecules and small ribosomes.
Explanation:
Prokaryotes are organisms having only one cell (unicellular). In their cells, an organized nucleus is absent along with other membrane-bound organelles. Examples include bacteria and archaea. The prokaryotic cell mainly consists of the plasma membrane, cytoplasm, DNA and ribosomes. Some prokaryotes have special structures such as flagella, pili, fimbriae, etc. Flagella help in the locomotion and pili or fimbriae are used for the attachment to host cells and other surfaces.
Their cells contain large quantities of genetic material (DNA and RNA). A single, large circular strand of DNA is found in the central part of the cell (nucleoid) and contains most of the genes. The ribosomes found in prokaryotes are smaller in size. A large number of ribosomes are present inside a prokaryotic cell. The shape and composition of ribosomes are slightly different than those in eukaryotic cells.
There are four nitrogenous bases that makes DNA. These are A, T, G and C. If a DNA strand has eight pairs of nitrogenous bases, the eight bases can be
1. AA GG TT CC
2. GC GG AT CG
3. AT TA GG GC
4. GA AG GC GG
Like this, there can be 65,536 different sequences with ATCG.
Since we have 4 nitrogenous bases, pairing will make 4 X 4 = 16 combinations. If we have to make 8 pairs of bases, the number of possible sequences would be 4 to the power 8.
Answer: THERE WILL BE 65,536 DIFFERENT SEQUENCES OF 8 BASES.
Volcanic eruptions cause magma to rise through cracks or weaknesses in the Earth's crust and when the pressure is released magma explodes causing a volcanic explosion. Hope this helps! :)
Answer:
Answer: The correct option is C) It produces ATP.
Photosynthesis is the process by which green plants prepare their own food using CO₂ and H₂O in the presence of sunlight. It is primarily divided into light reaction and dark reaction.
The light reaction takes place in the thylakoid membranes of the chloroplast. In this reaction, energy from sunlight is captured by the chlorophyll pigment via a series of chemical reactions. This results in the formation of two high energy chemical compounds, which are ATP and NADPH.
These compounds are further used in the dark reaction for the synthesis of food ( which is glucose).
Thus, it produces ATP is true for the light reaction of photosynthesis.
