Answer:
They do not contain chromosomes. (Ans.C).
Explanation:
Cyanobacteria also known as blue-green algae, they are heterogeneous group of photosynthetic prokaryotic organisms. Like prokaryotes such as bacteria, cyanobacteria lack endoplasmic reticulum, mitochondria, membrane bound nucleus, and Golgi apparatus. Bacteria are simpler than other organisms, and single celled microbes.
Both bacteria and cyanobacteria reproduce through the asexual method either by binary fission in unicellular, multiple fission in colonial form or by spore formation, and fragmentation in filamentous species.
The positively charged particle located at the center of an atom is the proton.
Think <em>p </em> in <em>p</em>roton and <em>p</em>ositive. Neutrons are also located in the nucleus of an atom, but they have a neutral charge (<em>neu</em>tron and <em>neu</em>tral).

Dilated cardiomyopathy is a heart disease which causes the heart chambers to thin and stretch , growing larger. It make it harder for the heart to pump blood to the rest of the body.
Extensive molecular alteration is failing heart at single cell resolution by single nucleus RNA which is nearly 600,000 nuclei in left .It occurs when heart's blood pumping Chambers's chambers enlarge or dilated. It occurs because the heart's walls became thickened , which makes it harder for the heart to pump blood.
when hypertrophy cardiomyopathy , ventricles size remains normal and thickening of the walls may block blood flow out of ventricles. This happen by progressing to dilated cardiomyopathy is rare.

Final speed - Initial speed / time.
50.0 - 20.0 / 5.0
30.0 / 5.0
= 6.0 (km/h)/s
Correct choice is B.
