Reason: Adenine pairs with thymine and guanine pairs with cytosine. Just do the opposite paired letter of the DNA strand
Answer:
they attach to the bones.
Answer:
C) They are compressed during inhalation.
Explanation:
Birds breathe through rigid lungs that are located in the animal's thoracic region. The trachea of birds divides into bronchi that branch inside the lungs into very thin tubes called parabronchials or parabroncholes, which are irrigated by blood capillaries that allow gas exchange.
In birds there are no pulmonary alveoli (as in mammals), but air capillaries that depart from the parabroncholes. Oxygen gas passes from these capillaries to the blood capillaries, thus causing gas exchange.
In the lower portion of the bird's trachea, before branching the bronchi, we can find the syringe, a bag-like structure that has vocal cords responsible for the birds' scream and song. Most of the time, the sound emitted by birds serves to attract the mate, mark territory and prevent birds of the same species against some predator or other danger.
Answer:
A
Explanation:
We can't see the graph, but I think I found the worksheet online, and so the graph is attached.
The answer cannot be B, as we are looking at a graph of pH, not temperatures. Therefore, we cannot draw this conclusion
The answer cannot be C, as pepsin is a digestive enzyme, and it works best at pH of around 2.
The answer cannot be D, because we can see that arginase and salivary amylase work at pH 7 and above, which is not acidic
The answer is A, because the lines for each enzyme are different, each peaking at a different pH. These peaks represent their optimum temperatures, and the hills of the peak represent the range in which they can work
