Answer:

Pili

Explanation:

The first external structure is the pilus (plural: pili). A pilus is a thin, rigid fiber made of protein that protrudes from the cell surface. The primary function of pili are to attach a bacterial cell to specific surfaces or to other cells. But how does the pilus know exactly what surface to attach to? Along the length of the pilus are adhesin proteins. The word 'adhesin' should remind you of the word 'adhesive' These molecules aid in the attachment of the pilus and are specific to the target surface.

Bordetella pertussis is the bacteria that causes whooping cough. Bordetella has pili coated with adhesins that can identify the mucosal surface of the respiratory tract and will stick to only that surface, allowing it to adhere to and infect those cells.

The use of which material can substitute for copper and reduce copper mine production?
Lesechka [4]

Answer:

Glass

Explanation:

Copper is a good conductor of electricity and this is why it is used in electrical equipment to transmit electrons with the least resistance. Cable conductors are made of copper and used to transmit data. Copper is now being replaced by optic fiber that is made of glass. Instead of using electrons, fiber optic transmits data using photons – which transmits more data rate than copper.

How can nuclei accommodateall of our genetic material<br> (3,000,000,000 base pairs)?
mr_godi [17]

Answer:

By forming chromatin and in the condensed form of chromosomes

Explanation:

The human genome contains around 3 billion base pairs which are located in the nucleus of all cells. In order to accomodate such large genomic information, DNA is maximally supercoiled during mitosis and meiosis processes to form condensed structures called chromosomes. Humans have 23 pairs of chromosomes per somatic cell. The supercoiling process is assisted by a family of proteins called histones, which interact with DNA and regulate its conformation. The complex between DNA and histones within the nucleus is called chromatin. When chromatin is supercoiled it form chromosomes (in eukaryotic cells).
