Igneous rocks are formed by hot melted magma coming from the Earth's core that crystalizes when gets in contact with air. They can be either intrusive or extrusive. B) <em>Large mineral crystals.</em>
<h3>
What is the igneous rock?</h3>
These rocks come straight from the interior of the Earth.
A liquid mass of silicate composition comes from the Earth's core. This melted mass comes at an extremely high temperature.
Magma begins to cool and solidify during its ascent to the Earth's surface. It solidifies and crystallizes into igneous rock following the magnetic field orientation.
Thre are two types of igneous rocks
• plutonic rocks ⇒ in areas close to the terrestrial crust ⇒ intrusive
• volcanic rocks ⇒ on the surface ⇒ extrusive
According to this description, the correct option is B. <em>Large mineral </em><em>crystals</em><em>.</em>

Answer:
Explanation:
The acid is becoming less acidic. Similarly, when an alkali is diluted with water the concentration of OH - ions decreases. This causes the pH of the alkali to fall towards 7, making the solution less alkaline as more water is added.
Answer:
<h2>e) 3/4
</h2>
Explanation:
As given;
Black (B) is dominant over red (b), so B is dominant over b.
Solid (S) is dominant over spotted color(s), so S is dominant over s.
Offspring of BBss and bbss individuals are:
Gametes of parent BBss are Bs, Bs and gamete of bbss are bs, bs
offspring are : all Bbss
Cross between these offspring is; Bbss×Bbss
Gametes of parent Bbss are: Bs and bs as given that the genes are linked.
Bs, bs × Bb, bs
Offspring are = BBss, Bbss, Bbss, bbss
Black spotted (B_ss) = 3/4
Answer:
I think B)
Explanation:
What your asking isn't that clear but if you said 'producers' is a kind of plant that creates their own food and the process is called photosynthesis.
But at the same time your question says "this plant take in oxygen and release carbon dioxide during just like animals and other living things" Im not sure that plants are the ones to take in oxygen and release carbon dioxide so....
I'm sorry if this didn't answer your question.
Yes, it does, but not the way people think. it doesn't gain it from the weight of all the people. the earth takes mass from elsewhere, as our population continues to grow.
