The iron-rich minerals present in the magma align themselves with the already existing magnetic field of the Earth. When the magma starts to cool down, the iron rich minerals are the first to solidify first. The magnetic field of the Earth align these minerals as the needle of the compass. The alignment of these iron-minerals is fixed once the magma is solidified completely.
Hence, the given blanks can be filled with 'iron and solidify'. respectively.
According to the research, angiotensin II (A) stimulates constriction of the glomerular inlet in response to a drop in overall blood pressure.
<h3>What is angiotensin II?</h3>
It is a potent vasoconstrictor derived from the effect of angiotensin converting enzyme on angiotensin I.
It acts directly on the arterioles and by stimulating the secretion of aldosterone; for example, it increases extracellular volume and peripheral vascular resistance.
Therefore, we can conclude that according to the research, angiotensin II (A) stimulates constriction of the glomerular inlet in response to a drop in overall blood pressure.

Answer:
Both statements are true
Explanation:
Many small tree saplings are competing for sunlight on the forest floor because tree saplings in forest floors are often deprived of adequate light as a result of the shade created by bigger trees in the forest. <em>Hence, the saplings jostle for light in order to effectively carry out light-requiring physiological activities such as photosynthesis and chlorophyll synthesis.</em>
The West Nile virus a virus that <em>generally affects the central nervous systems of birds - the primary host. It is transmitted from one bird to another through contact and by a vector - the mosquito</em>. The virus is also capable of being contracted by humans where it causes fatal neurological disorders.
