The transfer of genes during bacterial conjugation involves the pili.

<h3>Pili</h3>

Bacterial pili (singular: pilus) are special outgrowths on the surface of some bacterial cells that act as conjugal tubes during the process of transferring genes from one cell, the donor, to another, the recipient.

The pili extend from the donor to the recipient and then form channels through which genes are transferred.

Hydras and jellyfish both live in a freshwater lake that is slowly being acidified by the runoff from a chemical plant built ups
Pavlova-9 [17]

Answer:

Jellyfish

Explanation:

  • The mode of reproduction that is used by hydra to produce offsprings is asexual whereas the jellyfish is capable of reproducing sexually.
  • When an organism reproduces asexually then the rate at which the offspring are produced is faster, however, there is a lack of genetic diversity as the offsprings are produced from a single parent.
  • However, in case of sexual reproduction there is more variation and hence in case of a changing environment such as acidification of a lake by a runoff, there is a better chance of jellyfish to survive as it reproduced by sexual reproduction and thus has the ability to give rise to an offspring which will carry the trait to be more resistant.

Through the process of simple diffusion, materials move across a cell membrane
Leviafan [203]

Answer:

The correct answer is A from an area of higher concentration to an area of lower concentration

Explanation:

Diffusion is one of the most important membrane transport process which helps in the transport of small molecules and gases across the plasma membrane from higher concentration region to the region of low concentration until the concentration of the transported molecule becomes equal at both sides.

    As the molecule move along the concentration gradient no external energy is needed to carry out simple diffusion.
