<span>Firstly, producers get their energy energy from the sun through photosynthesis, creating or producing nutrients in the plant. A herbivore consumer can then eat it getting it's nutrients so, consumers rely on producers for their food but decomposers rely on a carnivore or omnivore (consumer) to eat some species of a consumer. The decomposer, lets say a earth worm eats and consumes the rest of the animal breaking it down to it's core nutrients. So I guess you could say decomposers rely on carnivores/omnivores to kill each other and herbivores, and herbivores/omnivores rely on producers for nutrients to eat</span>
In molecular biology, DNA replication is the biological process of producing two identical replicas of DNA from one original DNA molecule. This process occurs in all living organisms and is the basis for biological inheritance. DNA is made up of a double helix of two complementary strands. During replication, these strands are separated. Each strand of the original DNA molecule then serves as a template for the production of its counterpart, a process referred to as semiconservative replication. Cellular proofreading and error-checking mechanisms ensure near perfect fidelity for DNA replication.[1][2]
In a cell, DNA replication begins at specific locations, or origins of replication, in the genome.[3] Unwinding of DNA at the origin and synthesis of new strands results in replication forks growing bi-directionally from the origin. A number of proteins are associated with the replication fork to help in the initiation and continuation of DNA synthesis. Most prominently, DNA polymerasesynthesizes the new strands by adding nucleotides that complement each (template) strand. DNA replication occurs during the S-stage of interphase.
DNA replication can also be performed in vitro (artificially, outside a cell). DNA polymerases isolated from cells and artificial DNA primers can be used to initiate DNA synthesis at known sequences in a template DNA molecule. The polymerase chain reaction (PCR), a common laboratory technique, cyclically applies such artificial synthesis to amplify a specific target DNA fragment from a pool of DNA.
Answer:
density = Mass/volume
therefore, d= 13/5 = 2.6g/cm3
Explanation:
please change subject of your question next time, this is maths or phy not biology :-)
Answer:
a) A beaker filled with 1 liter of deionized water? - water will flow into the bag so its volume will increase. The solution is <u>hypotonic</u>
b) A beaker filled with 1 liter of 10% sucrose solution? - water will flow out of the bag so its volume will reduce. The solution is <u>hypertonic</u>
c) A beaker filled with 1 liter of 2% sucrose solution - the volume of water in the bag will stay the same as the two solutions are in equilibrium. The solution is <u>isotonic</u>
Explanation:
Water moves by osmosis through a semi-permeable membrane. Osmosis describes the simple diffusion of water molecules.
Water molecules will move from a high concentration to a low concentration.
- If the bag of 2% sucrose solution is placed in a beaker of deionized water, the concentration of water in the deionized water is in the beaker higher than in the bag (because the water in the bag contains 2% sucrose). Therefore, the water in the beaker will move from a high concentration outside the bag to a lower concentration inside the bag
- If the bag of 2% sucrose solution is placed in a beaker of 10% sucrose solution, the concentration of water in the bag is higher than in the beaker (because there is more sucrose in the beaker). Therefore, the water in the bag will move from a higher concentration inside the bag to a lower concentration outside the bag.
- When the concentration of water is equal, the movment of water molecules reaches an equilibrium and there will be no change in the volume of water in the bag
