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:
Thymine= 60 ng
Guanine= 20 ng
The complementary base pairing occurs between adenine and thymine and guanine and cytosine bases.
Explanation:
According to the Chargaff rule, a double-helical DNA molecule has an equal number or equal amount of adenine and thymine bases since adenine always pairs with thymine. Similarly, the amount of guanine base is equal to that of the cytosine base.
Chargaff rule is based on the complementary base pairing between purine and pyrimidine bases. According to the given information, the amount of adenine is 60 ng. Therefore, the cell would have 60 ng thymine. Similarly, the amount of the cytosine base in the cell is 20 ng which means that the cell would have 20 ng of guanine base.
Answer:
Watery, sometimes foul-smelling diarrhea that may alternate with soft, greasy stools.
Fatigue or malaise.
Abdominal cramps and bloating.
Gas or flatulence.
Nausea.
Weight loss.
Explanation:
because the parasite is traveling through the intestine(which is a very important body part in you body)
Answer:
I think this might be the answer
Explanation: The answer is the same for every diploid species. It is half the number of chromosomes in somatic (body) cells. The number of cells in gametes (sex cells) is n and the number in somatic cells is 2n. For fruit flies gametes have 4 chromosomes, for mice, 20, for humans 23, for chimpanzees 24.
Hope this helps and stay safe.
Answer/Explanation:
The DNA in all living organisms is made up of 4 bases, adenine, thymine, guanine, cytosine. The RNA replaces thymine with uracil, making 5 types of nucleotide. The number of nucleotide pairs in a genome can range from half a million up to 100,000 million - meaning there are an exponential number of combinations of these 4 bases.
Imagine an organism exists that has only 2 nucleotides (<u><em>this is over 200,000x smaller than even the smallest bacterial genome</em></u>). If we allow any nucleotide at each of the 2 positions, then we have 4x4 (4²) or 16 possible combinations of sequences. For a nucleotide length of 4, the total number of possible combinations are 4⁴ or 256.
Since we are dealing with many millions of nucleotides, there are essentially infinite combinations of nucleotides, giving rise to the variation that produces over 20 million organisms on the planet.
