a. The development of the southeastern part of the United States affected many species of animals, including the red wolves. The red wolves were seen as a species that is not useful and not wanted, and on top of that dangerous. Apart from the fact that the development led to destruction of the habitat of the wolves, so lot of them died out because of loss of habitat, the hunting played an even bigger role. As there were more and more people, and the encounters were becoming more often, and the wolves also had less food and started to attack the domestic animals, the hunters got activated and they almost killed the wolves to extinction, with only 20 individuals left.

b. Before the development of the southeastern apart of the United States, the red wolves were in relatively large number. This also meant that the genetic diversity was much greater among the red wolf population, resulting in healthy, stable, and strong population of this predator. When the situation came that only 20 individuals were left, then the genetic diversity shrinking to a very low level. Those 20 wolves did not had any other choice then to breed between each other, so in only couple of generations the genetic diversity become extremely low. That is very dangerous for a population, as if some of the individuals have some bad mutation or disease carrying with them, they can affect all the rest and the population may die out easily.

c. Apart from the capturing and breeding of the red wolves, the other method to increase their population is to reintroduce them into the areas where they once lived, under condition that it is a protected area. By reintroducing enough individuals so that the population can reproduce in a healthy manner, the red wolves population can easily and quickly reestablish itself in a natural manner, also contributing to restoring the natural order in their former habitat.

If ethyl alcohol contains almost as much energy as the original pyruvic acid, what can you infer about the efficiency of ferment
shusha [124]

Explanation:

Fermentation has a comparatively low efficiency as it produces the same amount of energy, whereas aerobic  respiration produces up to 38 molecules of ATP .

Aerobic respiration in the mitochondria utilizes oxygen for the production of ATP in the Krebs’ or Citric acid cycle via the oxidization of pyruvate( through the process of glycolysis in the cytoplasm).

Within cells, aerobic respiration may not occur due to several factors:

  • - a lack of inorganic, final electron acceptors
  • -incomplete or lack of a complete electron transport system
  • -missing genes for enzymes within the Kreb's cycle

Thus, they utilize other means for the generation of energy in the form of ATP and to replenish NAD+ an oxidized form of NADH, the main electron carrier in glycolysis. Pyruvate is produced in the cytoplasm via glycolysis- it is also used as an electron acceptor in a process called fermentation.

  • Net production of ATP in fermentation: 2 ATP
  • Net production of ATP in aerobic respiration ≈38 ATP

Further Explanation:

overall in aerobic respiration: C6H12O6 (glucose) + 6 O2 → 6 CO2 + 6 H2O + ≈38 ATP

In all eukaryotic cells mitochondria are small cellular organelles bound by membranes, these make most of the chemical energy required for powering the biochemical reactions within the cell. This chemical energy is stored within the molecule ATP which is produced. Respiration in the mitochondria utilizes oxygen for the production of ATP in the Krebs’ or Citric acid cycle via the oxidization of pyruvate( through the process of glycolysis in the cytoplasm).

Oxidative phosphorylation describes a process in which the NADH and FADH2 made in previous steps of respiration process give up electrons in the electron transport chain these are converted it to their previous forms, NADH+ and FAD. Electrons continue to move down the chain the energy they release is used in pumping protons out of the matrix of the mitochondria.

This forms a gradient where there is a differential in the number of protons on either side of the membrane the protons flow or re-enter the matrix through the enzyme ATP synthase, which makes the energy storage molecules of ATP from the reduction of ADP. At the end of the electron transport, three molecules of oxygen accept electrons and protons to form molecules of water...

  • Glycolysis: occurs in the cytoplasm 2 molecules of ATP are used to cleave glucose into 2 pyruvates, 4 ATP and 2 electron carrying NADH molecules. (2 ATP are utilized for a net ATP of 2)
  • The Citric acid or Kreb's cycle: in the mitochondrial matrix- 6 molecules of CO2 are produced by combining oxygen and the carbon within pyruvate, 2 ATP oxygen molecules, 8 NADH and 2 FADH2.
  • The electron transport chain, ETC: in the inner mitochondrial membrane, 34 ATP, electrons combine with H+ split from 10 NADH, 4 FADH2, renewing the number of electron acceptors and 3 oxygen; this forms 6 H2O, 10 NAD+, 4 FAD.

Which protective covering of the brain provides passageways for cerebrospinal fluid (csf) to drain into the superior sagittal si
IceJOKER [234]

The protective covering of the brain that provides passageways for cerebrospinal fluid (CSF) to drain into the superior sagittal sinus is called the arachnoid mater.

 

To add, the arachnoid mater is the middle of three layers that make up the meninges, or membranes, that surround the spinal cord and brain.
