spider has no tail and has no stinger
<u>Answer:</u>
<em>The minerals that are formed </em><em>deep beneath the earth surface</em><em> comes to the earth's surface by following two ways.</em>
<u>Explanation:</u>
It can come out in the form of volcano or lava and once cooled will form an igneous rock. It can also come out due to the movement of tectonic plates and can for metamorphic rock.
Basalt and granite are the commonly found minerals. The mineral crystals mostly form rocks. The lava on the surface sometimes gets cool so quickly that it fails to crystallise some minerals.
Physical biological and chemical
Answer:
Helicase
Explanation:
The DNA double helix is unzipped by the enzyme *HELICASE*. The enzyme breaks the hydrogen bond between the bases thereby causing the strands of the double helicase to unzip. The action of the helicase enzyme uses energy from ATP. The unzipping of the double helix does not occur in a swift move. One end of the DNA molecule with 5'-3' is opened up showing the antiparallel single strands. The end that is opened is termed INITIATION SITE of replication. The opening look like someone standing with legs wide open. The wide opening is called REPLICATION FORK. The single strands of the fork are usually unstable but their stability is maintained by the DNA-binding-proteins. Having opened the double helix, the replication would then continue in the 5'-3' direction of one of the two antiparallel single strands.
Answer: none
Explanation:
If we have that the color characteristic is regulated by the dominant gene R, by crossing two blue flowers with the recessive gene r, no violet flower will be obtained, since the rule of incomplete dominance describes that phenotypes can be obtained intermediates of homozygous parents, however in the case, we only have 2 parents with the same recessive conditions, which do not contribute to generate the violet, to produce one of the parents should have a gene that expresses the color red
