PLEASE HELP WILL MARK BRAINLIESTMitosis occurs in a series of tightly regulated stages. Disruption of any of these stages can hinder chromosomal transmission during mitosis. Suppose that vinblastine, a chemotherapeutic medication that specifically targets and
disrupts microtubules, is applied to a cell culture undergoing mitosis.
Which of the following best explains how this medication will affect the transmission of chromosomes to daughter
cells?
The daughter cells will remain genetically identical to their parents because microtubules are only involved in
degradation of the nucleus during prophase.
The daughter cells will not be genetically identical. Microtubules are involved only in alignment of chromosomes
at the midline during metaphase and separation during anaphase.
The daughter cells will not be genetically identical because microtubules are only required for a process in which
homologous chromosomes exchange genetic information during prometaphase.
The daughter cells will not be genetically identical because microtubules are involved in the formation of the
spindle apparatus during prophase, attachment to the kinetochore during prometaphase, alignment of
chromosomes at the midline during metaphase, and separation during anaphase.

phaneritic textures in which phaner means visible so phaneritic textures are standard of impertinent volcanic rocks. these rocks crystallized gradually under the surface of earth. when the magma cools deliberately then the ores have chance to develop and produce long crystals.

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.

you know they are heterozygous for a trait because they have it as jj or jj.
