Blood pumps through arteries due to contraction of the arterial walls but flows more freely through veins because there is littl

Excitable cells like those found in muscle tissue are expected to be present in higher quantities in arteries than in veins.

<h3>What are Excitable cells?</h3>

Excitable cells are defined as those cells that are capable of generating electrical impulses when stimulated. Example of such cells include:

Neurons,

muscle cells( smooth, skeletal and cardiac)

Endocrine cells.

The artery is made up of higher amount of smooth muscles than the veins therefore, excitable cells like those found in muscle tissue are expected to be present in higher quantities in arteries than in veins.

Bacterial conjugation

lord [1]

Answer:

Yes, these are correct.

Explanation:

Bacterial conjugation is the bacterial counterpart of sexual reproduction. Also known as horizontal gene transfer, it involves the transfer of genetic material from one F+ or Hfr bacterium to another F+ or F- bacterium.
The F or fertility factor is a crucial component of the bacterial plasmid and it accounts for the development of sex pili which are important for conjugation. An F+ cells contains the F-factor incorporated into its plasmid, whereas an F- cell lacks the F-factor and therefore cannot participate in conjugation.
Conjugation between an F+ and F- cell can result in the transfer of the F-factor to the F- bacterium.
An Hfr bacterium contains F-factor incorporated into its circular genome.
