Wetlands are important ecosystems for many reasons. Select all that apply.
vazorg [7]

A, B, & D.

Wetlands DO NOT increase the rate of extinction of mammals by creating a loss of habitat. Wetlands rather form a habitat for many organisms creating a rich microcosm of an ecosystem.

Explanation:

Wetlands are land areas that are seasonally or permanently submerged in water. They include marshlands, estuaries, deltas, swamps, floodplains, and etcetera.  The plants within wetlands, such as mangrove slow down water runoff hence allowing settling down of, sediments and pollutants hence ‘cleaning’ the water.

Due to this fact that wetlands slow water movement, these ecosystems are significant in reducing flooding by ‘storing’ flood water and releasing it slowly hence acting like flood controls.

The arrangement of homeotic genes along chromosomes of vertebrate and invertebrate animals corresponds to the expression pattern
Keith_Richards [23]

The arrangement of homeotic genes along chromosomes of vertebrate and invertebrate animals corresponds to the expression pattern of the genes along the anterior-posterior axis of the developing embryo.

<h3>What are homeotic genes?</h3>
  • Homeotic genes are a group of body pattern forming genes which control the development along the anterior- posterior axis of the developing embryo.
  • These encode transcription factors which control and specify the genes involved in body patterning. These provide identity to the segments during embryo formation.
  • Genes located in the 5’ end act on posterior side whereas the genes on 3’ end act on anterior region.
  • Homeotic genes are evolutionary conserved and control body specification, patterning and differentiation.
  • The loss of function of any of the gene changes the body pattern and affects the development.
