Which is used as evidence for the idea that multicellular organisms evolved from prokaryotes?
Mitochondria and chloroplasts have their own DNA
What is the process by which molecules move from high concentration region to low concentration region without the presence of membrane?
This process is called diffusion. It is the passive movement of particles from high to low concentration, and is against a concentration gradient. Hope this helps!
Do photosynthesis occur in mitochondria?
nope. only in the chloroplast. in that there are two cycles, the light reaction and the Calvin cycle Light reaction light is taken in the plant water from the roots is broken down oxygen is released from the plant leaves ATP and NADPH (a high energy electron carrier) is produced (carries hydrogen) Calvin Cycle CO2 is taken in ATP is used as energy NADPH is used to lower ativiation energy (after the calvin cycle, NADPH become NADP+)
Where can DNA be found other than the nucleus?
DNA (deoxyribonucleic acid) is the 'language' that genes are 'written in'. The DNA in the nucleus composes the genome (complete set of genes) of the organism to which the cell belongs. Thus the human genome is the genome of the DNA within the nucleus of human cells. But DNA, in plants and other photosynthetic eukaryotes, is found composing a completely different genome within the chloroplasts. And in most eukaryotes including animals, plants and fungi, their is also a separate mitochondrial genome composed from DNA in the mitochondria. The theory of endosymbiosis explains the presence of DNA in mitochondria and chloroplasts.
How are plant and animal cells similar?
The plant and animal cells are similar in many ways.There are only a few differences like presence of cell wall, presence of chloroplasts, absence of centrioles in plants. The only thing not similar about the two is a plant cell has a cell wall and chloroplasts. Everything else is the same. Animal cells and plant cells both have a nucleus, Golgi bodies, endoplasmic reticulum, ribosomes, and mitochondria
What concept explains the presence of mitochondria in cell?
The concept that explains the presence of mitochondria in cells is the endosymbiotic theory. Mitochondria in cells derived from the extra embryonic membranes.
What determines where energy production will continue into the mitochondria?
The presence of oxygen. Oxygen is needed for mitochondria
what are some exceptions to the cell theory?
Presence of extra-chromosomal DNA: Mitochondria and chloroplasts
What is contamination?
The unwanted presence of materials containing radioactive atoms on other materials.
Where does pyruvate processing occur?
Pyruvate processing occurs in the matrix of the mitochondria
What are you responsible for when analyzing a hazardous materials incident at the awareness level?
When analyzing a hazardous materials incident at the awareness level you are responsible for recognizing the presence of hazardous materials.
A materials ability to burn in the presence of oxygen?
A material's ability to burn in the presence of oxygen is called flammability.
How photoelectric scanning occurs?
A band of electrons is produced whenever light is shone on a most materials. Therefor, the absence or presence of these electrons can be detected to deduce the absence or presence of the materials.
What is the term for a materials ability to burn in the presence of oxygen?
Flammability
What is a term for a materials ability to burn in the presence of oxygen?
Flammability
Sound does not travel through a vacuum?
No. Sound is transmitted as vibrations, that pass from one group of atoms to the next, thus, it requires the presence of atoms that transport the sound wave.No. Sound is transmitted as vibrations, that pass from one group of atoms to the next, thus, it requires the presence of atoms that transport the sound wave.No. Sound is transmitted as vibrations, that pass from one group of atoms to the next, thus, it requires the presence of atoms that transport the sound wave.No. Sound is transmitted as vibrations, that pass from one group of atoms to the next, thus, it requires the presence of atoms that transport the sound wave.
What effect does the presence of oxygen have on the events that fallow glycolysis?
it helps the electron transport chain
