What is the Endangered Species Act? Describe one of its successes and explain some of the current controversies surrounding it.
frutty [35]

Answer:

The Endangered Species Act was formulated in 1973. This Act was made in order to protect the threatened and endangered species of both plants and animals and also to protect the habitats in which these species live.

One of the major success was that there were many species which actually recovered from this act. For example, the population of the Kirtland's warbler increased from 210 to 1415 from 1973 to 2005.

One of the major controversies which arose from this act was that the critics claimed that this act failed to show major recovery of animals. Out of the total 2000 endangered species listed, only 28 species were properly recovered.

Where in the cell does the krebs cycle part of cellular respiration occur ?
neonofarm [45]

Answer:

<u>In the mitochondrial matrix</u>

<u></u>

Explanation:

The mitochondria is an organelle within the cytoplasm of the cell.  It consists of an outer membrane, inner membrane, and matrix containing a gel-like substance. During aerobic respiration in mitochondria, cells break down sugars in the form of glucose into CO_{2} (carbon dioxide) and  H_{2} O (water) to obtain energy in the form of ATP or adenosine triphosphate.

aerobic respiration:

C6H12O6+ 6 O2        →      6 CO2 + 6 H2O + ≅38 ATP

(glucose)   (oxygen)         (carbon dioxide) + (water)

The Kreb's cycle involves several enzymatic reactions, where pyruvate derivatives obtained from glycolysis, are reduced and oxidized to harvest energy as ATP.
