why is the interaction of the respiratory and circulatory systems necessary for the frog survival please refer to oxygen and carbon dioxide?
In the circulatory system there is the distribution of oxygen to the body and in the respiratory system the gas exchange.
How is the respiratory and circulatory system of amphibians?Amphibians have three structures for breathing:
The lungsThe mucous membranes of the pharynx and mouthand The skin.The lungs are made up of two bags with no internal division. When still in the larval stage, they breathe through gills.
How does the circulatory system of amphibians work?Amphibians have a dual circulation, meaning the blood passes through the heart twice to complete the cycle. The blood reaches the heart, travels towards the lungs, returns to the heart and only then is carried to the body.
Whit this information, we can conclude that In the circulatory system there is the distribution of oxygen to the body and in the respiratory system the gas exchange.

Cellular respiration involves a reaction between glucose and oxygen to form_____
1: carbon dioxide
2: water
3: all of these
4: energy
Answer:
3. All of these
Explanation:
When the reaction of cellular respiration occurs, carbon dioxide and water is created while energy gets released.
Answer:
3: all of these
Explanation:
They actually form ATP, which is essentially energy. Byproducts are water and carbon dioxide. I would say all of these answers are true! Remember though, ATP (energy) is the main product while water and carbon dioxide are byproducts.
What drives plate movement?
A. Convection currents in the mantle.
B. Convection currents in the inner core.
C. Convection currents in the crust.
D. Oceanic currents
Answer: The answer is A, convection currents in the mantle.
Explanation: Plate tectonics move because they are carried along by convection currents in the upper mantle of the planet (the mantle is a slowly flowing layer of rock just below Earth's crust). Hot rock just below the surface rises and when it cools and gets heavy, it sinks again.

In DNA and RNA, what “codes for amino acids”?
combinations of nucleotides
combinations of sugars
combinations of proteins
combinations of strands
Answer:
The correct answer is - combinations of nucleotides
Explanation:
The codes for amino acids are encoded in the DNA and RNA in the form of the trinucleotide codons that contain three base sequences which copied in the complementary bases sequence mRNA and then decoded by the ribosome with help of tRNA to produce the original sequence in amino acid sequence or peptide chain.
This nucleotide is also code in the set of 3 base sequences similarly one amino acid is made up of the triplet code.

The complete question is as follows:
Regarding the General Adaptation Syndrome, a short term response to stress in which glycogen is broken down to glucose is characteristic of the stage. 1) Alarm reaction 2) Stage of resistance 3) Stage of exhaustion
Answer:
The General Adaptation Syndrome or GAS explains the pattern of responses that body experinces in response to prompted by a stressor. There are three phases of this syndrome:-
1. Alarm reaction:
Sympathetic system and Hypothalamopituitary axis activated by the stress result in reaction by body.
2. Stage of resistance:
The hormone that is releases continusoly in this stage by the zona fasciculata layer of adrenal cortex is cortisol to maintain arousal.
3. Stage of exhaustion:
In abscence of enough blood sugar or glucose in the body, the body initiates breakdown of the glycogen (stored sugar in muscles mosty) with the help of hormone known as glucagon to covert it to glucose so that it can be used by the cellular respiration.
You are called to investigate a lake in your home town, where the residents fear that a broken pipe from the local sewage treatment plant has turned the formerly pristine lake eutrophic. You test the water and find very low levels of oxygen. What stage of euthrophication is this lake in?
Answer:
The correct answer is - The decomposers decompose dead algae and plants which take up most of the oxygen.
Explanation:
Eutrophication is taken place when there is a high amount of nutrients, minerals are present in a waterbody which allow algae to grow rapidly and cause depletion of oxygen due to the decomposition of dead organisms. There are the following stages in the eutrophication process:
- rapid growth of Algae and other plants
- due to algal bloom, the sunlight is blocked, and plants and organism start dying.
- The decomposers take up most of the oxygen by decomposition
- The animals start dying without oxygen
Which animal is likely to have the highest basal metabolic rate (oxygen consumption per unit body mass)?
Answer:
Hummingbirds
Explanation:
The animal which is likely to have the highest basal metabolic rate (oxygen consumption per unit body mass) Is the Hummingbird.
The hummingbird have a very small mass when compared to other animals or humans but they perform a lot of activities which is also the main reason why they consume volumes of nectar which is proportional to its size.
