Which of the following statements about bird respiration is FALSE?

Biology
1 answer:
zheka24 [161]3 years ago
7 0

Answer:D

Explanation: The pulmonary air sacs of birds only permit a unidirectional flow of air through the lungs. Unidirectional flow means that air is inhale and exhale through one trachea alternatively. This means the bird lungs only receive largely fresh air which has a high oxygen content during inhalation and do not receive fresh during exhalation. While air flow bidirectional in mammals.

According to the simulation, _______ helps predators to survive by allowing them to sneak up on their prey. a. camouflage b. mim
SIZIF [17.4K]

Answer: a.Camouflage

Simulation is a deception in the characteristics of the organism which favors it's survival in the environment. Camouflage is a kind of simulation, in which the organism adapt the color or shape according to the surrounding environment in order to remain undetected by a prey and a predator. For example, chameleon is a reptile, which can change it's color according to the surrounding environment. It changes it's color to green in grass and remains brown in the tree bark in order to eat insects and remain undetected from prey and predator population.

Therefore, According to the simulation, camouflage helps predators to survive by allowing them to sneak up on their prey.

There is an error in the above model.
ollegr [7]

ATP hydrolysis is the lysis of the molecule mediated by water. It releases a phosphate group and energy. It is a reversible reaction. <em>(a) Reversible ATP hydrolysis. (b) added energy on the left and released energy on the right.</em>

   

------------------------

ATP is a significant molecule involved in many of the cellular metabolic routes. <em>These metabolic processes can either form it or break it.</em>

ATP provides energy to many different functions in the organism.

ATP means<em> adenosine tri-phosphate</em>. It is composed of adenosine (an <em>adenine plus a ribose</em>), and three phosphate groups.

<u><em>Note</em></u><em>: you can also find adenosine Diphosphate (two phosphates) and adenosine monophosphate (one phosphate).</em>

Oxygens from the phosphate groups only have a single bond to phosphate (there are no hydrogen bonds).

These single bonds, known as <em>phophoanhydrid bonds</em>, have a negative charge and tend to repel each other, making the molecule unstable.

So phosphate groups repel each other, and a considerable amount of energy is applied to keep them united. So phophoanhydrid bonds are high energetic bonds.

The forces that keep the phosphate groups together accumulate potential energy.  

If these bonds are broken, part of this potential energy would be released.

When talking about breaking the molecule, we are referring to ATP hydrolysis. And the released energy is used in different cellular processes that require energy.

ATP Hydrolysis is the molecule lysis mediated by a water molecule.

                      ATP  +  H₂O   ⇄   ADP  +  Pi  +  Energy

​

Pi is the released inorganic phosphate group.

This is a reversible reaction, meaning that the ADP can go back to ATP.

                 ADP  +  Pi  +  Energy   ⇄   ATP  +  H₂O

<em> (a) What is this a model of?</em>

  • This model represents the reversible ATP hydrolysis.

  • In the superior part of the image, we can see an ATP molecule composed of adenine, ribose, and three phosphate groups. The yellow star behind represents the accumulated energy.

  • When ATP hydrolysis, it loses a phosphate group and part of the energy that was keeping this group in the molecule.

  • An ADP is composed after hydrolysis. We can see this molecule in the inferior area of the image.

  • ADP molecule is composed of adenine, ribose, and two phosphate groups.

  • Because hydrolysis is a reversible process, by adding a new phosphate inorganic group and energy, we can get a new ATP.

<em>(b) Explain how you would change the model to make it correct? </em>

  • What is wrong with this model is that instead of showing released energy during the hydrolysis process, it shows energy added to the reaction.

  • In the same way, instead of showing added energy to the reversible reaction, it shows released energy.

Added energy and released energy must be changed.

  • Added energy should be on the left
  • Released energy should be on the right
