Answer:
Courtney is looking at Prokaryotic Cell.
Explanation:
Ok, when Courtney is observing the science experiment, and finds a cell that includes DNA and has a nucleoid region but does not have nucleus, it is a prokaryotic cell and only the single-celled organisms of the domains Bacteria and Archaea are classified as prokaryotes, where pro means before and kary means nucleus.
Let's explain what is a prokaryotic cell: prokaryotes are unicellular organisms that lack organelles or other internal membrane-bound structures. Therefore, they do not have a nucleus, but, instead, generally have a single chromosome: a piece of circular, double-stranded DNA located in an area of the cell called the nucleoid. And most prokaryotes have a cell wall outside the plasma membrane.
<h2>Cytokinesis in animal cells</h2>
Explanation:
- The force for cytokinesis is generated by kinesin motors on microtubule bundles that form the contractile ring:This statement is false because cytokinesis in animal cells starts with the assembly of contractile ring,contractile band consists of actin and myosin(microfilaments) which catalyse cleavage furrow formation
- As the contractile ring constricts, its thickness increases to keep a constant volume:This statement is false because thickness remains constant
- The midbody forms from bundles of actin and myosin: This statement is false because contractile ring forms bundles of actin and myosin whereas midbody is formed from microtubules
- Local activation of Ran GTPase triggers the assembly and contraction of the contractile ring:This statement is false because local activation of Rho mediates profilin binding to actin and helps in assembly and contraction of contractile ring
The four letter string comes out to be FFFF
Is this a multiple choice question?
The correct answer is D. The sloth gains nor loses anything from this interaction yet the insects have a nice place to hatch their young.
