Explain why the cane toad was a failure as a biological control method in Australia.
Answer:
The cane toad was a failure as a biological control method in Australia because:
-The cane toad eats many native species and often out-competes native species for food and breeding sites, leading to the decline of natives.
-Breeding habits made the cane toads a very invasive species.
Explanation:
A rare form of mineral that is usually very clear and brightly colored
An uncommon and clear splendidly hued mineral is known as a gemstone. The variety frequently results from minor components inside the mineral.
Models incorporate emeralds (green from chromium) and amethysts (purple from iron). Gemstones, similar to precious stones and emeralds, are exceptionally valued for their lucidity and energetic varieties, which result from explicit minor components inside the minerals. For instance, emeralds get their green tone from limited quantities of chromium, while amethysts are purple because of the presence of iron. Notwithstanding, variety alone can be questionable for distinguishing proof in light of the fact that numerous minerals can show a large number of varieties in view of their pollutions.Complete question as follows:
A rare form of mineral that is usually very clear and brightly colored is known what ?
What is most likely to result immediately after a rainforest in Brazil is clear cut
Answer:
The immediate effect of destruction of rainforest in Brazil is the global warming.
Explanation:
The brazil rainforest is present near the amazon basin and most of the amazon rain forest extends in Brazil. The Brazil rainforest as part of the Amazon rainforest provides oxygen to the earth. This acts as the lungs of the earth.
It is the home of many plant and animal species. It has two-thirds of the world's plant species. The world's 20 % oxygen comes from these forests.
If the forest will clear, then the amount of carbon dioxide gas increases. It leads to global warming and air pollution. Because carbon dioxide is a greenhouse gas and it increases the temperature of the earth. This is the immediate impact of the destruction of the brazil rainforest.
The forest is destroyed every day for various purposes such as excessive fishing, grazing of animals, and building of dams. Due to the destruction of the forest, many animals lose their habitat, which results in an ecological imbalance.

The tropopause is _____.
Going upward from the surface, it is the point where air ceases to cool with height, and becomes almost completely dry. More formally, the tropopause is the region of the atmosphere where the environmental lapse rate changes from positive, as it behaves in the troposphere, to the stratospheric negative one. Following is the exact definition used by the World Meteorological Organization:
The boundary between the troposphere and the stratosphere, where an abrupt change in lapse rate usually occurs. It is defined as the lowest level at which the lapse rate decreases to 2 °C/km or less, provided that the average lapse rate between this level and all higher levels within 2 km does not exceed 2 °C/km.[1] for example

B.both occur in the mitochondria and result in producing more ATP.
C.both are anaerobic and occur inside the mitochondria.
D. both occur in the cytoplasm and result in producing more ATP.
Both the processes takes place in mitochondria and result in producing more ATP. The correct option is B.
What is mitochondria?Mitochondria are bilayer cell organelles that produce the majority of the chemical energy required to power the cell's biochemical reactions (mitochondrion, singular).
The mitochondrial energy is stored in a small molecule known as adenosine triphosphate (ATP).
Mitochondria convert chemical energy from food in the cell to energy usable by the host cell by using oxygen available within the cell.
The process is known as oxidative phosphorylation, and it occurs within mitochondria.
The Krebs cycle and electron transport chain processes occur in mitochondria and result in the production of more ATP.
In turn, ATP serves as the primary energy source for the majority of biochemical and physiological processes, including growth, movement, and homeostasis.
Thus, the correct option is B.

conversion of glucose units into starch
conversion of fructose and glucose units to form sucrose
conversion of cellulose into glucose units
The question discusses the biochemical processes of the conversion of glucose into starch, fructose and glucose into sucrose, and cellulose into glucose.
Explanation:The processes described involve the conversion of different types of sugar units. Firstly, the conversion of glucose units into starch occurs in plants as a means to store excess glucose produced during photosynthesis. This involves linking glucose molecules together to form a polysaccharide starch. Secondly, the conversion of fructose and glucose units to form sucrose is another common biochemical process. Sucrose is a disaccharide made by combining a glucose unit and a fructose unit. Lastly, the conversion of cellulose into glucose units represents the breakdown process where organisms, especially those living in the gut of animals, can convert cellulose back into glucose for their energy needs.

Hans Selye called the body's response to stress:
Hans Selye called the body's response to stress the general adaptation syndrome (GAS). It consists of three stages: the alarm stage, resistance stage, and exhaustion stage.
Explanation:Biology - High SchoolHans Selye called the body's response to stress the general adaptation syndrome (GAS). The GAS consists of three stages: the alarm stage, the resistance stage, and the exhaustion stage.
In the alarm stage, the body perceives a stressor and activates the fight-or-flight response. This leads to the release of stress hormones, increased heart rate, and heightened senses.
In the resistance stage, the body attempts to cope with the ongoing stress. It adapts to the stressor and tries to maintain physiological balance. However, the body remains on high alert and may experience symptoms of chronic stress.
In the exhaustion stage, prolonged exposure to stress overwhelms the body's resources. Physical and mental exhaustion may occur, increasing the risk of illness and disease.
