Small crystals and found in magma chambers! Hope these are correct!

Explanation:

Answer from: 20shearcorr

Small crystals.

EXPLANATION:

Extrusive igneous rocks are formed when the magma reaches the Earth's surface and most of the extrusive (volcanic) rocks have very small crystals.

The examples of the Extrusive rocks include rhyolite, basalt, obsidian, and andesite.

These rocks emit on the surfaces where they form the small crystals. These rocks are used in building construction and statues.

Igneous rocks are very unique because of their mineral and chemical substances.

Answer from: Quest

you are certainly talking about this picture:

a: is the label of the white square, it is showing the replication fork, formed by helicase (d) ==> so it is the site of dna separation and replication

b: is a new dna brand that is following directly the replication fork, so it is continuous ==> built continuously from 5' to 3

c: dna polymerase cannot replicate dna on its own, it needs the of their proteins, and one of them plays the role of a clamp which fixes the dna with the dna template and increases the processivity of the enzyme. ==> stops polymerase from falling off the template.

d: is the enzyme responsible for forming the replication fork (helicase) ==> unwinds and separates dna into two strands

e: is the delayed strand, it is built in the opposite sense of the helicase, so dna will be built in fragments ==> built fragments from 5' to 3 joins

and finally f: is the enzyme that builds the new dna strand (dna polymerase) ==> adds nucleotides to make a new dna helix.

In german cockroaches, curved wing (cv) is recessive to normal wing (cv+). bill, who is raising cockroaches in his dorm room, finds that the frequency of the gene for curved wings in his cockroach population is 0.6. in his friend joe’s apartment, the frequency of the gene for curved wings is 0.2. one day joe visits bill in his dorm room, and several cockroaches jump out of joe’s hair and join the population in bill’s room. bill estimates that, now, 10% of the cockroaches in his dorm room are individual roaches that jumped out of joe’s hair. what is the new frequency of curved wings among cockroaches in bill’s room? 0.69 0.4 0.5 0.31 0.20
