Ftsz is a bacterial cytoskeletal protein that forms a contractile ring involved in binary fission. its function is analogous to the cleavage furrow of eukaryotic animal cells the cell plate of eukaryotic plant cells the mitotic spindle of eukaryotic cells the microtubule-organizing center of eukaryotic cells

Option A, the cleavage furrow of eukaryotic animal cells

Explanation:

FtsZ stands for  "Filamenting temperature-sensitive mutant Z". The role of Ftsz is very essential during the period of cell division. While a cell starts dividing, it is the first protein to reach to the site of cell division and performs the task of aquiring proteins that are essential for producing new cell wall. Mostly, bacteria's divide by  formation of an FtsZ ring  also known as Z-ring.

Hence, option A is correct.

corona the outer atmosphere of the sun, temp. may reach 2,000,000 c

chromosphere middle layer of the sun's atmosphere

photosphere visible surface of the sun

convection zone layer of the sun which energy travels by convection from the radiative zone to the photosphere

radiative zone layer of the sun which energy is transferred away from the core by radiation

core very dense center of the sun

nuclear fusion process by which tow or more low-mass atomic nuclei fuse to form another, heavier nucleus.

radiation when energy is transferred as electromagnetic waves

convection the process in which heat is transferred by the circulation or movement of matter

differential rotation the way the sun rotates, rotating faster at its equator than at higher latitudes

sunspots dark areas that form on the surface of the sun

solar flare an explosive release of energy that can extend outward

prominences huge loops of cool gas that extend outward from the photosphere

not sure but try c two haploid cells
