Answer:
Rare species of plants can be cloned so they don't go extinct. To do this, stem cells are taken from the <u>meristems</u> of the plant.
Explanation:
Stem cells can be described as cells which are undifferentiated and have a capability to divide into specialized cells. In plants, the stem cells are located in the meristems of the plant. Out of these cells, all the specialized tissues and organs form in a plant.
Cloning is a method to produce identical copies of a gene or an entire organisms. The method of cloning is now being used widely to make organisms that are at the verge of extinction.
The photosynthesis takes place in the <span>chloroplasts, which are just found in plant cells. This is probably the name that those green organelles have.

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.
The particles vibrate but they are tight together so they don’t move past each other
