Choose the correct statements about meiosis. Enter your response as three consecutive numbers without commas or spaces. (such as 123) 1Meiosis allows organisms to pass on some traits to their offspring.
2Meiosis allows organisms to pass on all of their traits to their offspring.
3Meiosis produces sex cells with the same number of chromosomes as somatic (body) cells.
4Meiosis produces sex cells with half the number of chromosomes of somatic (body) cells.
5If an organism has a useful trait, meiosis ensures that it is passed down to the next generation.
6If an organism has a useful trait, meiosis provides a possibility that it is passed down to the next generation.

answer: substrate concentration. enzymes work best when there is a high enough substrate concentration for the reaction they catalyse.

the dna molecules have a negative charge because of the phosphate groups in their sugar-phosphate backbone, so they start moving through the matrix of the gel towards the positive pole. power is turned on and dna fragments migrate through gel (towards the positive electrode).

explanation:

a = executive branch; b = judicial branch

answer and explanation;

volcanic rocks are igneous rocks which form from lava, molten rock which has been thrust out of a volcano onto the surface of a rocky body such as an asteroid, planet, or dwarf planet.  

plutonic rocks are igneous rocks which form from subterranean chambers of molten rock or magma. plutonic rocks make up the base of continental crust as well as oceanic crust. their slow rate of formation causes them to be coarse grained since there is plenty of time for large crystals to form before the magma solidifies into rock.

the textural difference is that plutonic rocks are more coarse grained than volcanic rocks. plutonic rocks are coarse grained while volcanic are fine grained ; glassey or fragmental. since fine and coarse are adjectives the decision as to whether a rock is fine or coarse grained is generally made on the bases of whether or not the individual crystals can be seen in most if the rock.
