Canaliculi structure of

vovangra [49]

Bone canaliculi are microscopic canals between the lacunae of ossified bone. The radiating processes of the osteocytes (called filopodia) project into these canals. These cytoplasmic processes are joined together by gap junctions. ... In cartilage, the lacunae and hence, the chondrocytes, are isolated from each other.

Question 4

Juliette [100K]

Answer:

In eukaryotes, thousands of chemical reactions are able to take place in separate compartments called organelles.

Explanation:

Organelles are specific cellular structures that are the means of compartmentalizing the various functions that occur within cells.

Examples of organelles and their functions are:

- Nucleus: contains DNA and in it occur the replication of this molecule and its transcription into RNA.

- Rough endoplasmic reticulum: protein synthesis and conjugation of these molecules occurs.

- Mitochondrion: houses all oxidative phosphorylation reactions and the electron transport chain for ATP synthesis to occur.

The organelles are then the structures that allow the development of the multiple functions that a cell has.

The other options are not correct because:

Bacteria is a prokaryotic organism.
Prokaryote refers to simple organisms that lack organelles.
Proteins are biomolecules that allow the structure and function of living beings.

A bacteria culture starts with 200 bacteria and in 1 hour contains 400 bacteria. How many hours does it take to reach 2000 bacte

RSB [31]

Answer:

At 0hr it was 200 bacteria

At 1 hr it doubled and was 400

Means: at every 1 hr the population of the bacteria doubles

400 bacteria = 1hr

2000 bacteria = X

X = 2000 × 1 / 400

X = 5 hrs
