Answer: 1000 nm
Explanation:
Bacteria are the type of biological cell. They constitute a large domain as they are found every where on the earth.
These are few micrometer in length which means 200-700nm . It depends on the type of the bacterial cell. The bacteria are the first organism that appeared on earth.
They are found in water, on land, desert, hydro thermal vent, snow et cetera. These are variable in shape.
<h2>Evolution of phylogenies </h2>
Explanation:
- The genome of the endosymbiont is all the more firmly identified with individuals from the gathering in which it initially developed, while the nuclear genome of the inundating living being has its own evolutionary trajectory.
- The accumulation of various inheritable attributes after some time which prompted the arrangement of another species
- Nuclear and organellar genes advanced at various rates, clouding developmental connections.
- Some mitochondrial genomes have been decreased definitely in size, losing a large number of the protein genes encoded in creature mtDNA just as a few or all mtDNA-encoded tRNA genes.
- At ∼6 kb in size, the mitochondrial genome of Plasmodium falciparum (human intestinal sickness parasite) and related apicomplexans is the littlest known, harboring just three protein genes, profoundly divided and improved little subunit (SSU) and enormous subunit (LSU) rRNA genes, and no tRNA genes.
- In stamped differentiate, inside land plants, mtDNA has extended generously in size (>200 kb) if not in coding limit, with the biggest known mitochondrial genome right now.
Answer:
Microtubules composed of tubulin protein.
Explanation:
The cytoskeleton is composed of three well defined filamentous structures: microtubules, microfilaments, and intermediate filaments. Each of these filamentous structures is a polymer of proteinic subunits united by weak, not covalent connections.
Microtubules are long hollo cylindric tubes with no ramifications of a diametre near to 25 nanometers. They are constituted by two subunits of tubulin protein which polymerize to form microtubules. These filaments shape the cell and are involved in intracellular transport. Microtubules extend from an organizing center near the nucleus to the cellular surface.
Answer:
25 years
Explanation:
Ossification is the process of bone tissue formation. Osteoblasts are responsible for the process of ossification. It begins when the fetus is three months old and goes on till 25 years of age. Upper limbs get ossified first, followed by lower limbs, sternum and vertebrae.
There are two types of ossification processes. When bone is directly developed using the primitive connective tissue (mesenchyme) it is called as intramembranous ossification, while in endochondral ossification cartilage is used as a precursor.
Answer: Meiosis is a process where a single cell divides twice to produce four cells containing half the original amount of genetic information. These cells are our sex cells – sperm in males, eggs in females. ... These four daughter cells only have half the number of chromosomes? of the parent cell – they are haploid.
