Answer:
1.Toad
2.Newt
3.Salamander
In addition to the frog, the other organisms that are classified as modern amphibians are toads and salamanders. Therefore, the correct option is A.
What are modern amphibians?Modern amphibians are a class of cold-blooded vertebrates that spend part of their life cycle in water and part on land. They are united under the taxon Lissamphibia. They are divided into three clades which are Urodela, Anura and Apoda. In addition to frogs, the other two groups of modern amphibians are toads and salamanders.
Snakes and lizards are reptiles, which are a different class of cold-blooded vertebrates. Opossums and koalas are marsupials, which are warm-blooded mammals, and sharks and skates are fish, which are cold-blooded vertebrates but are not classified as amphibians. Therefore, the correct option is A.

The results suggest the optimum temperature for the enzyme is between which two values?
A 15 °C and 35 °C B
35 °C and 45 °C C
35 °C and 55 °C D
45 °C and 55°C
Answer:D
Explanation:
The optimum temperature for the enzyme is between 45 °C and 55°C. Therefore, option (D) is correct.
What is an optimum temperature for enzyme?Most enzymes perform best at a temperature of around 98.6 degrees Fahrenheit (37 degrees Celsius). Additionally, some enzymes function well both at low and high temperatures. For instance, while animals in desert climates have enzymes adapted to higher temperatures, those in the Arctic have them adapted to lower optimal temperatures.
The reaction rate will accelerate as more hydrogen peroxide is added to the mixture because more substrate molecules can interact with the enzyme and produce more product as a result. As you increase the amount of H2O2 in your reaction, more foam is generated in your cup as a result.

compared to parasympathetic ganglia, sympathetic ganglia are __________.
Compared to parasympathetic ganglia, sympathetic ganglia are autonomic ganglia of the sympathetic nervous system that prepare the body for emergency situations, such as: defense or flight reactions to a dangerous situation.
In the parasympathetic ganglia, the axons of neurons are characterized by being very long and reach the very structure of the target organ before making contact with the second neuron.On the other hand, these ganglia activate the parasympathetic system that has to do with energy recovery situations such as: activating digestive secretions, reducing blood flow to the brain, which causes drowsiness.In the sympathetic ganglia, axons originate from neurons located in the lateral horns of the spinal cord and exit through the anterior roots of the spinal nerves, along with those of the motor neurons.These ganglia activate the sympathetic system that prepares the body for dangerous situations causing: increased heart rate, blood pressure, respiratory rate, etc.Therefore, we can conclude that compared to parasympathetic ganglia, sympathetic ganglia are autonomic ganglia of the sympathetic nervous system that prepare the body for emergency situations.

oxygen
Hemoglobin contains magnesium that gives the blood the red color when
exposed to oxygen
Hemoglobin contains iron that gives the blood the red color when exposed to
oxygen
Answer:
it contains iron that gives it the red color when exposed to oxygen
Human blood-red and not blue because Hemoglobin contains iron that gives the blood the red color when exposed to oxygen. The correct option is c.
What is hemoglobin?Hemoglobin is a red color pigment that is present in the blood. It contains a heme group that carries oxygen into the body and carries carbon dioxide outside the blood. It is red and in some animals, it is blue because of copper.
Hemoglobin is made up of four protein chains that each bind an additional ring-shaped chemical structure called heme. Our red blood cells are red because of the heme groups in hemoglobin. In turn, our blood is red because of the millions of red blood cells that it contains.
Therefore, the correct option is c. Hemoglobin contains iron that gives the blood a red color when exposed to oxygen.
