Answer:

The correct answer is the last option, that is, multigene families are similar or identical genes, whose evolution took place by gene duplication.

Explanation:

A member of a family of the associated proteins encrypted by an array of identical genes is known as a multigene family. It is considered that the origination of the multigene families has resulted due to the variation and duplication of a single ancestral gene.  

The multigene families make the assembly of the proteins comparatively quickly, as it assists in the simultaneous transcription of various genes at distinct locations.

Do Different cell types also have special duties, like building skin or bone, pumping out hormones, or making anti-bodies.
Schach [20]

Answer:

Yes, different cell types also have special duties, like building skin or bone, pumping out hormones, or making anti-bodies.

Explanation:

Cell is the basis structural and functional unit of a living organism. The body of a human is composed of trillions of cells that are organized in around 200 types of cells.

<u>A tissue is simply a group of specific kind of cell that have  a specific role.</u>

  • For example: The nervous system contains cells called neurons that have ability to transmit message from one place to another and allow us to respond to any environmental stimuli, such as heat, cold, danger etc.
  • Skin cell is composed of cells that have a role in protecting the body against the attack of harmful microbes. They also protect have role in building new skin cells and adding the protection to our body.
  • Blood cells have a role in providing us immunity (for example white blood cells) therefore, make us better able to protect ourselves from danger of diseases.
  • Muscle cells help us in moving our organs as well as allowing the whole movement from one place to another.

Thus we see that different types of cells have special functions and all these different cells coordinate with each other to make an organized and functioning body of a living organism.

Which gas is used by plants for photosynthesis and released by all living things during respiration?
Tju [1.3M]
During photosynthesis, plants take in carbon dioxide (CO2) and water (H2O) from the air and soil. Within the plant cell, the water is oxidized, meaning it loses electrons, while the carbon dioxide is reduced, meaning it gains electrons. This transforms the water into oxygen and the carbon dioxide into glucose
