<h3><u>Answer;</u></h3>

Evolutionary patterns observed in the fossil record are consistent with evolutionary processes occurring today.

<h3><u>Explanation;</u></h3>

Three spine stickleback is a model organisms for studies in evolution because; Stickleback fish are small and have short generation times. These two characteristics make them easy to keep in a lab and useful for conducting genetic studies, since researchers can follow several generations of fish in a relatively short time.
Also, stickleback fish populations occur throughout the Northern Hemisphere in a wide range of environments, so researchers can compare different populations and study how they have changed over time in response to different environmental pressures.

ioda

Answer:

Birds can keep themselves warn without any external heat source which is not the case with reptiles and amphibians

Explanation:

Birds are able to generate heat means they are endothermic. They generate heat through various metabolic processes. They have air pockets beneath their feathers to insulate their bodies during cold temperatures. Feathers which are modified reptilian scales help birds to streamline their exterior body and structure feathers in a way that it insulates the body.

Some autoimmune disorders are thought to be caused by _________, which occurs when an infectious agent is composed of antigens w

EastWind [94]

Answer: adaptive immune response

Explanation:

Autoimmune disorders are caused by different microoorganism and drug which manipulates the immune system in a way that immune system become unable to recognise between self antigen and foreign antigen. In that case immune system treats foreign antigen as self antigen which cause systemic or organ specific damage.

The exact cause of autoimmune disorders is unknown and hence it is thought that it is caused by adaptive immune response which builds against self antigens and causes damage to the cells.

Hence, some autoimmune disorders are thought to be caused by adaptive immune response.
