The answer is C) extrusive igneous. This rock starts as magma, so you know it must be a type of igneous<span> rock. The question tells you that the rock forms when it is cooled by the water, so you know it is formed outside of the Earth's interior, therefore making it extrusive igneous rock.

C. More areas have polluted soil, reducing crop variety.
It literally tells you right there, though.
Plants<span> produce hormones and </span>respond to external stimuli<span>, growing towards sources of water and light, which they need to survive. A tropism is a growth in </span>response<span> to a </span>stimulus<span> and an auxin is a </span>plant<span> hormone produced in the stem tips and roots, which controls the direction of growth.</span>
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.
Lol D. Is correct... just sounds the most scientific don’t you think? But it’s also how nucleotides/ DNA works so yea
